In order to more clearly describe the features of the embodiments, detailed descriptions of matters known to those of ordinary skill in the art to which the following embodiments belong will be omitted. Moreover, in the drawings, portions irrelevant to the description of the embodiments are omitted, and like reference numerals are given to like portions throughout the specification.
Throughout the specification, when it is described that one component is "connected" to another component, it includes not only the case of "directly connected" but also the case of "connected with another component interposed therebetween". Also, when it is described that one component "includes" another component, it is meant that other components may be included, not excluded, unless otherwise specified.
First, the meanings of terms commonly used in this specification are defined.
"traffic related data" is a broad concept including various data that may affect traffic, such as traffic regulations, traffic conditions (e.g., the number and speed of vehicles traveling on a road, etc.), road conditions (e.g., road conditions such as whether or not the vehicle is frozen or under construction, etc.), weather conditions, and the like. The traffic-related data may also include identification information and location information of devices that facilitate the collection and provision of the traffic-related data.
The "traffic safety information" is information that helps to maintain traffic safety, and is information indicating, for example, a road congestion due to a large number of vehicles, a poor road surface condition, an accident occurring ahead, an ongoing construction ahead, or a road section with a high number of accidents ahead. The user driving the vehicle confirms the traffic safety information and drives the vehicle appropriately according to the information, so that an accident can be prevented.
The "vehicle running information" may include, as various data related to the running of the vehicle, for example, an instantaneous speed, an acceleration, an engine Revolution Per Minute (RPM), whether or not a brake is operated, a position of the vehicle, a tire air pressure, a temperature, a load weight measurement value, a remaining fuel amount, a driving date, a driving time, a driving distance, and the like, of the vehicle collected at a predetermined cycle.
An "On-Board Unit (OBU)" as a device capable of performing computation and communication provided in a vehicle refers to a device that processes and computes data collected by a sensor (e.g., a laser radar sensor) of the vehicle, or communicates with an external device. In the embodiments described in this specification, the in-vehicle apparatus communicates with a roadside apparatus described later, so that traffic-related data collected by a sensor of a vehicle can be transmitted to the roadside apparatus or traffic safety information can be received from the roadside apparatus.
A "Roadside apparatus (RSU)" is an apparatus provided at a Roadside to communicate with an in-vehicle apparatus. In the embodiments disclosed in the present specification, the roadside apparatus may be provided independently at the roadside at predetermined intervals, or may be provided in existing infrastructure such as street lamps or signal lamps. Additionally, in embodiments disclosed in the present specification, a roadside apparatus may include a processor and a memory to perform a node (node) role of a blockchain network. In addition, in the embodiments disclosed in the present specification, the roadside apparatus may also have various types of apparatuses (e.g., a camera, a position measurement sensor, an acoustic sensor, etc.) capable of collecting traffic-related data.
For terms not described above, meanings thereof will be described below as necessary.
Fig. 1 is a diagram illustrating a blockchain-based traffic management system according to an embodiment. Referring to fig. 1, a block chain based traffic management system according to an embodiment may include a network 10, a roadside apparatus 20, a Variable Message Sign (VMS) 30, a vehicle 40, a user terminal 50, and a server 100. In addition, although not shown in fig. 1, according to other embodiments, the blockchain-based traffic management system may also include various types of traffic infrastructure.
The network 10 is configured to enable wired/wireless communication between a plurality of roadside apparatuses 20, which are apparatuses constituting a block chain network, and a user terminal 50, and a plurality of servers 100.
As described above, the roadside apparatus 20 is provided at a roadside to communicate with an in-vehicle apparatus provided in the vehicle 40, and may operate as a node of a block chain network for storing traffic-related data. In particular, the roadside apparatus 20 may receive traffic-related data from an in-vehicle apparatus or a user terminal 50 provided in the vehicle 40, or may directly collect traffic-related data by a sensor or the like provided in the roadside apparatus. The roadside apparatus 20 may also transmit the received or collected traffic-related data to the server 100 through the network 10. In addition, the roadside apparatus 20 may also receive traffic safety information from the server 100 and transmit it to an in-vehicle apparatus or a user terminal 50 provided in the vehicle 40.
The variable information board 30 is configured to display traffic-related data or traffic safety information, and according to an embodiment, a part of the plurality of roadside devices 20 may be further connected to the variable information board 30. The roadside apparatus 20 connected to the variable information panel 30 may also display traffic-related data or traffic safety information on the display screen of the variable information panel 30.
The vehicle 40 may be provided with an onboard device that may pre-store or directly measure or receive traffic related data (e.g., license plate number, vehicle identification number, vehicle speed, vehicle location, etc.) associated with the vehicle from the vehicle 40. For example, the vehicle 40 may be provided with sensors such as a camera, an infrared sensor, a radar (radar), and a LiDAR (LiDAR), and traffic-related data collected by these sensors may be transmitted to the on-board device.
According to one embodiment, the vehicle 40 may also include a digital tachograph (DTG, below). The DTG may collect the vehicle travel information as described above in real time. The DTG may directly store the collected vehicle travel information or transmit the vehicle travel information to an external device such as an in-vehicle device. The DTG may be configured as a device separate from the in-vehicle apparatus, but may also be implemented as a single device by integrating the DTG with the in-vehicle apparatus.
The in-vehicle apparatus may transmit traffic-related data or vehicle travel information stored in advance or received from the vehicle 40 to the roadside apparatus 20. Hereinafter, for convenience, the work performed by the in-vehicle device provided to the vehicle 40 will also be described as being performed by the vehicle 40.
The user terminal 50 refers to a terminal held by a user who drives the vehicle 40. The user terminal 50 may collect traffic-related data directly and transmit it to the roadside apparatus 20, or transmit it to the server 100 through the network 10. In addition, the user may confirm the traffic safety information through the user terminal 50 or receive a reward for the user's vehicle 40 traveling, and for this, the roadside apparatus 20 or the network 10 may transmit the traffic safety information or the reward to the user terminal 50. In this case, the provided reward is a cryptocurrency mined from at least one of the plurality of nodes constituting the blockchain network or an electronic certificate provided by another organization. An application for collecting traffic-related data and transmitting it to the outside, or receiving traffic safety information or rewards from the outside may be provided at the user terminal 50. In addition, the user terminal 50 directly collects vehicle travel information and thus may also function as a DTG.
In the block chain based traffic management system according to an embodiment, various types of traffic-related data may be collected using at least one of the roadside apparatus 20, the vehicle 40, and the user terminal 50.
An example of collecting traffic-related data using at least one of the roadside apparatus 20, the vehicle 40, and the user terminal 50 will be described in detail below. For example, at least one of the above devices captures an image of the surroundings of a road with a camera held by the device, and analyzes the captured image, thereby making it possible to grasp the number of vehicles on the road, the state of the road surface, and the like. In addition, at least one of the above-described devices can grasp the distance to the front and rear vehicles by using a sensor (e.g., radar or lidar) held for measuring the distance. In addition, at least one of the above devices can grasp weather conditions such as heavy fog, rain, and snow by using a sensor held by the device.
The collected traffic-related data may be stored in a blockchain network that may include at least a portion of the plurality of roadside devices 20, the plurality of user terminals 50, and the server 100. The roadside apparatuses 20, the user terminals 50, and the server 100 may each operate as nodes (nodes) constituting a block chain network, wherein some of the nodes may operate as verification nodes (validation nodes) for performing verification when storing data. The traffic related data are dispersedly stored in a plurality of nodes after being verified by the verification nodes, and the dispersedly stored data are connected with each other through hash values (hash values), so that the reliability of the data can be ensured.
As described above, the traffic-related data may also include identification information and location information of the device from which it was collected. That is, the traffic-related data may include personal information of a user's name, phone number, location of the user, and the like, and thus the user may not want the traffic-related data to be dispersedly stored in the external device.
To solve such a problem, according to an embodiment, traffic-related data is encrypted and stored in the user terminal 50, and only a hash value of the encrypted data may be stored in the blockchain network. If necessary, the roadside apparatus 20 or the server 100 refers to the hash value stored in the block and requests data from the user terminal 50. In response to such a request, the user terminal 50 decodes the stored encrypted data using the private key, and then transmits the decoded data to the roadside apparatus 20 or the server 100. Alternatively, the user terminal 50 transmits the encrypted data and the private key to the roadside apparatus 20 or the server 100, and the roadside apparatus 20 or the server 100 may decode the encrypted data using the received private key. In this way, not only can the reliability of the data stored in the user terminal 50 be ensured, but also sensitive personal information can be prevented from leaking to the outside.
The vehicle 40 and the user terminal 50 provide traffic-related data to the system so that rewards may be received from the server 100. Thus, the user may be motivated to provide traffic related data.
The manner in which traffic-related data is stored in the blockchain network is briefly described below. Fig. 2 is a diagram illustrating a structure of a block for storing traffic-related data and the like according to an embodiment.
The block chain network can be distributed and stored with digitalized information, and each block (block) as a basic unit constituting the block chain network is composed of a block header (header) and a block body (body).
Referring to fig. 2, traffic-related data is stored in a block body of a block. In addition to the traffic-related data, the block body of the block may store vehicle travel information, traffic safety information, or the like.
The block header of a block stores a hash value for a previous block and a hash value for the corresponding block. The hash value for the corresponding block refers to a hash value obtained by converting data included in a block body of the corresponding block using a predetermined hash function (hash function). The hash value for the corresponding tile is stored as a "hash value for the previous tile" at the tile header of the next tile so that the tiles can be connected to each other. In addition, the block header of the block may store a version (version) or a random number (nonce) value, which relates to a general block chain technique, and thus a detailed description thereof will be omitted.
The blocks generated in this way are stored in a distributed manner in nodes constituting a block chain network, and the hash value for a specific block is stored in the block header of the corresponding block and the block header of the next block at the same time, so that the reliability between the data stored in a distributed manner can be ensured.

Hereinafter, operations performed in the block chain based traffic management system according to an embodiment will be described separately according to embodiments.
1. Embodiments for storing vehicle travel information in a blockchain network and providing rewards based on vehicle travel information
According to one embodiment, a blockchain-based traffic management system may collect vehicle travel information and store the vehicle travel information to a blockchain network, and provide a reward to a user based on the stored vehicle travel information.
In the present embodiment, the DTG provided in the vehicle 40 may be included in a user terminal 50 in a broad sense, and the user terminal 50 such as a smartphone may be configured to perform the operation of the conventional DTG. Therefore, in the following description of the present embodiment, the description is made on the premise that "the user terminal 50" includes the DTG.
The user terminal 50 collects vehicle travel information, generates a block including the vehicle travel information (hereinafter, referred to as a "travel information block"), and stores it in the blockchain network. At this point, the server 100 facilitates generating the tiles, receiving and storing the generated tiles to the blockchain network.
The user terminal 50 may periodically collect vehicle driving information, which may include, in addition to the above information, impact event information generated when a vehicle collision is detected, abnormal event information generated when a vehicle has a fault, dangerous driving event information generated when an overspeed, a sudden start, a sudden stop, and the like.
The user terminal 50 or the server 100 extracts data of an accident-prone area, a safe driving area by time period, a driver characteristic, etc. by analyzing the vehicle travel information, and can use the extracted data to evaluate and reward safe driving of the vehicle 40.
According to an embodiment, in order for the user terminal 50 to generate the driving information tile, the server 100 may transmit tile generation permission information (e.g., a registration key) to the user terminal 50, and each of the user terminals 50 may generate and transmit unique tile generation permission information. The server 100 may manage information on the user terminal 50 that generates the tile using the tile generation permission information.
The user terminal 50 may encrypt the vehicle travel information using the tile generation permission information received from the server 100 and generate a driving information tile. In this way, by encrypting, transmitting, and storing the vehicle travel information, forgery or falsification of the information can be prevented.
The driving information block may include a hash value for each of the block number, the vehicle travel information, and the block generation permission information of the corresponding block, and may include a hash value for a previous block and a hash value for the corresponding block. The process of hashing the corresponding chunk is as follows: that is, the hash value obtained by using the hash value included in the corresponding block (hash value for each of the previous block, the block number, the vehicle travel information, and the block generation permission information) as an input of the hash function is the hash value for the corresponding block. At this time, "block number" is a value indicating a block generated for the next time by the corresponding block. Since each driving information block includes a hash value for the previous block, all blocks are connected in a blockchain, whereby forgery or falsification of information can be effectively prevented.
The user terminal 50 may convert and encrypt the vehicle travel information, the block generation permission information, and each driving information block into a hash value using a hash function. At this time, the user terminal 50 uses "Secure Hash Algorithm 1 (SHA 1)" which is a Hash function with a relatively small amount of calculation, so that the present embodiment can be smoothly executed even in a mobile terminal with a relatively low operation capability.
The user terminal 50 may configure the hash value converted from the vehicle travel information, the block generation permission information, and the block number in a Merkle tree (Merkle tree) form, so that the hash value for the current block may be generated. In detail, the user terminal 50 first obtains hash values (leaf data) corresponding to each of the vehicle travel information, the block generation permission information, and the block number, and connects the obtained hash values and the hash value for the previous block two by two to obtain a new hash value (parent data for the leaf data). The user terminal 50 repeats the above process until the hash values cannot be paired two by two, i.e., until only one hash value remains and the last hash value (the root of the mercker tree) can be stored to the block header of the block. At this time, the root of the merkel tree becomes a hash value for the current chunk, and can be used when generating the next chunk. The hash value for the current block is associated with all information included in the block and can therefore be used in determining whether the information is counterfeit or tampered.
When generating the hash value corresponding to the tile generation permission information, the user terminal 50 may generate the hash value using random information into which the seed information is converted from the server 100. At this time, the seed information may be an inherent identifier assigned to the user terminal 50 by the server 100, and the user terminal 50 converts the seed information an arbitrary number of times corresponding to the number of block numbers of the driving information blocks to be generated, so that random information may be generated. At this time, it is assumed that random information having the same value is always generated when specific seed information is arbitrarily converted a specific number of times. According to the assumption, for example, random information generated by arbitrarily converting the seed information "100" twice is always "45".
The user terminal 50 may generate a hash value corresponding to the chunk generation permission information using the chunk generation permission information and the random information. By using random information in generating the hash value in this manner, security is improved, and the possibility of forgery or falsification of information can be prevented.
The user terminal 50 may transmit the generated driving information block to the server 100 through the network 10. Upon receiving the tile generation permission information from the server 100, the user terminal 50 may be able to generate the driving information tile even in a state of being disconnected from the network 10 or the server 100. After reconnecting with the server 100, the user terminal 50 may transmit the tile generated in the unconnected state to the server 100.
According to an embodiment, the user terminal 50 may generate bonus information based on the vehicle travel information included in each driving information block and transmit it to the server 100. At this time, "bonus information" refers to information of the kind and number of bonus awards provided to the user driving the vehicle 40. For example, the user terminal 50 analyzes the vehicle travel information, grasps the number of times of speeding, the number of times of sudden start or sudden stop, and whether or not the vehicle collides, and calculates a safe driving index by comprehensively considering these, and generates bonus information based on the calculated safe driving index. For example, the server 100 may send the user terminal 50 encrypted money or electronic certificates, etc. as the award. As such, by providing a reward for safe driving, the user can be induced to drive the vehicle 40 safely.
In the above embodiment, the user terminal 50 generates the driving information block and the bonus information, but the invention is not limited thereto, and the server 100 may generate the driving information block and the bonus information. That is, the server 100 receives the vehicle travel information from the user terminal 50, and may generate the driving information block using the block generation permission information for the user terminal 50. In addition, the server 100 may also generate bonus information based on the vehicle travel information received from the user terminal 50 or included in the directly generated driving information block.
According to an embodiment, the user may input vehicle travel information or additional information related thereto through the input/output part 52 of the user terminal 50, for example, when the impact event information is generated, the user may input information on a specific reason or situation for occurrence of a vehicle collision through a touch screen or the like, and the thus input information may be transmitted to the server 100.
According to an embodiment, the user terminal 50 may set the collection periods of the information according to the types of the information included in the vehicle travel information, respectively. For example, the user terminal 50 may measure and collect the accumulated travel distance every day, or may measure and collect the speed of the vehicle in units of one second.
According to an embodiment, the server 100 may determine whether the driving information block received from the user terminal 50 is forged or falsified. In detail, the server 100 generates a hash value for a current tile by combining tile generation permission information, a tile number, and seed information corresponding to the user terminal 50 that transmitted the corresponding driving information tile, and may determine whether the tile is forged or tampered based on the generated hash value.
Fig. 4 to 6 are flowcharts for explaining an embodiment in which the blockchain-based traffic management system stores vehicle travel information to a blockchain network and provides a bonus based on the vehicle travel information according to an embodiment.
Referring to fig. 4, in step 401, vehicle travel information is collected by the user terminal 50. In step 402, the user terminal 50 receives tile generation permission information from the server 100. In step 403, the user terminal 50 generates a driving information block using the received block generation permission information and vehicle travel information and stores the driving information block in the blockchain network.
Fig. 5 shows the detailed steps included in step 403 of fig. 4. Referring to fig. 5, the user terminal 50 converts the seed information received from the server 100 into random information in step 501. In step 502, the user terminal 50 generates a hash value corresponding to the chunk generation permission information using the chunk generation permission information and the random information. In step 503, the user terminal 50 generates a hash value corresponding to the vehicle travel information and the block number, and generates a driving information block using the generated hash value.
Fig. 6 shows the steps performed after step 403 of fig. 4. Referring to fig. 6, the user terminal 50 calculates a safe driving index based on the vehicle travel information included in the driving information block. In step 602, the user terminal 50 generates bonus information based on the calculated safe driving index and transmits it to the server 100. In step 603, the server 100 provides the user terminal with the bonus according to the bonus information.
On the other hand, although the detailed process of storing the vehicle travel information in the blockchain network is described in the present embodiment, it may be implemented in a similar process when storing traffic-related data or traffic safety information in the blockchain network in addition thereto.
According to the present embodiment, by storing the vehicle travel information to the blockchain network, it is possible to prevent the user or the like from arbitrarily forging or tampering the vehicle travel information. In addition, according to the present embodiment, it is possible to determine whether the user drives safely based on the vehicle travel information, and provide a reward to the user according to the determination result, so that the user can be encouraged to drive safely.
2. Embodiment for generating traffic safety information based on traffic-related data, determining traffic safety behavior corresponding to the traffic safety information, and guiding the traffic safety behavior
The blockchain-based traffic management system according to an embodiment may also generate traffic safety information based on traffic-related data stored in the blockchain network, determine appropriate behavior from the generated traffic safety information to maintain traffic safety, and guide a user. In addition, the block chain based traffic management system according to an embodiment may also pay the user a corresponding reward when the user performs an appropriate action to maintain traffic safety.
The roadside apparatus 20 or the server 100 may generate traffic safety information based on traffic-related data recorded in the blockchain network by analyzing road conditions around the vehicle 40 or conditions around the roadside apparatus 20. For example, the traffic safety information may include contents of congestion on the road ahead, contents of presence of a risk factor (e.g., construction section) on the road ahead, contents of fogging on the road ahead, and the like. The roadside apparatus 20 or the server 100 may generate traffic safety information by analyzing an image taken of a road or analyzing the position and speed of a vehicle.
In addition, the roadside apparatus 20 or the server 100 may determine an appropriate behavior for maintaining traffic safety (hereinafter, referred to as "traffic safety behavior") from the traffic safety information. For example, when the traffic safety information includes the content of congestion on a road ahead, the roadside apparatus 20 or the server 100 may determine "entering a detour road" or "vehicle deceleration" as the traffic safety behavior. Alternatively, for example, when the traffic safety information includes the content of the presence of the risk factor on the road ahead, the roadside apparatus 20 or the server 100 may determine "entering a detour road", "changing a lane", or "decelerating a vehicle" as the traffic safety behavior. Alternatively, for example, when the traffic safety information includes the content of the front road fogging, the roadside apparatus 20 or the server 100 may determine "vehicle deceleration" as the traffic safety behavior. The traffic safety behavior thus generated may also be stored to the blockchain network.
Traffic safety behavior may also be determined individually per user. For example, when the driving experience of the user driving a specific vehicle 40 is small or old, the roadside apparatus 20 or the server 100 may determine "driving into a detour road" as a traffic safety behavior when there is a sharp turn ahead of the corresponding vehicle 40. To this end, the traffic-related data may also include information related to the user identity of each user's age, driving experience, and the like.
The roadside apparatus 20 or the server 100 may also consider the position of the roadside apparatus 20 that contributes to collecting and storing traffic-related data when determining traffic safety information and traffic safety behavior from the traffic-related data. For this reason, when storing the traffic-related data in the blockchain network, the roadside devices 20 may also store the position information of the roadside devices 20 together.
A specific example of the roadside apparatus 20 or the server 100 determining the traffic safety behavior will be described below with reference to fig. 7. Fig. 7 is a diagram for explaining a process in which the block chain based traffic management system determines traffic safety behaviors based on traffic-related data according to an embodiment.
Referring to fig. 7, construction is underway on the road ahead of the vehicle 40. The roadside apparatus 20 around the area where construction is underway collects images of roads photographed by cameras as traffic-related data, whereby the roadside apparatus 20 or the server 100 can generate traffic safety information having contents where danger factors exist on the roads.
The roadside apparatus 20 or the server 100 may determine "driving onto the detour" as the traffic safety behavior based on the traffic safety information described above. At this time, the roadside apparatus 20 or the server 100 may receive information on the destination and the predetermined route of the vehicle 40 from the user terminal 50, thereby determining a detour route and guiding the user. For example, when receiving information that the predetermined route of the vehicle 40 is route a, the roadside apparatus 20 or the server 100 guides a detour route to a destination through route B, and may display the contents of the detour route at the user terminal 50.
At this time, the roadside apparatus 20 or the server 100 may select an object guiding traffic safety information and traffic safety behavior based on the identification information and the location information of the user terminal 50 or the vehicle 40 included in the traffic-related data. For example, when the position of the construction section is determined based on the position information of the roadside apparatus 20 photographing the road under construction and it is determined that the vehicle 40 approaches the corresponding construction section through the position information of the user terminal 50 or the vehicle 40, the corresponding vehicle 40 is selected as an object that needs to guide traffic safety information and traffic safety behavior related to the construction section.
The roadside apparatus 20 or the server 100 may determine traffic safety information and traffic safety behavior corresponding to a specific user terminal 50 or vehicle based on the identification information and the location information of the user terminal 50 or the vehicle 40 included in the traffic-related data. For example, the roadside apparatus 20 or the server 100 may determine traffic safety information for roads within a prescribed distance from the user terminal 50 or the vehicle 40 and traffic safety behaviors corresponding thereto as corresponding to the respective user terminal 50 or the vehicle 40. The roadside apparatus 20 or the server 100 may transmit the traffic safety information and the traffic safety behavior thus generated to the user terminal 50, and the user may confirm the traffic safety information and the traffic safety behavior displayed through the input/output unit 52 of the user terminal 50.
Alternatively, the roadside apparatus 20 or the server 100 may determine traffic safety information and traffic safety behavior determined from traffic-related data collected by a specific roadside apparatus 20 as corresponding to the corresponding roadside apparatus 20 and guide it to the user terminal 50 or the vehicle 40 within a prescribed distance from the corresponding roadside apparatus 20.
In the case where it is determined that the vehicle 40 performs the traffic safety action corresponding thereto, the roadside apparatus 20 or the server 100 may pay a reward to the corresponding vehicle 40 or the user terminal 50 corresponding to the corresponding vehicle 40.
Alternatively, when it is determined that the vehicle 40 within a prescribed distance from a specific roadside apparatus 20 performs a traffic safety action corresponding to the corresponding roadside apparatus 20, the roadside apparatus 20 or the server 100 may pay a reward to the corresponding vehicle 40 or the user terminal 50 corresponding to the corresponding vehicle 40.
Referring to fig. 7, when the vehicle 40 detours the path B according to the traffic safety behavior, the roadside apparatus 20 or the server 100 may pay a reward to the user terminal 50 or the vehicle 40. At this time, the roadside apparatus 20 or the server 100 may determine that the vehicle 40 enters the route B based on the position information of the user terminal 50 or the vehicle 40. Alternatively, if the roadside apparatus 20 around the route B communicates with the user terminal 50 or the vehicle 40, the roadside apparatus 20 or the server 100 may determine that the vehicle 40 has entered the route B.
When the roadside apparatus 20 is connected to the variable information panel 30, traffic safety information and traffic safety behavior corresponding to the roadside apparatus 20 can be displayed through the variable information panel 30.
It has been described above that the traffic safety information and the traffic safety behavior can be displayed through the input/output section 52 of the user terminal 50. At this time, in order to arouse the interest of the user and increase the participation, the user terminal 50 may provide a game to implement traffic safety behavior as a task. In this regard, description will be made with reference to fig. 8.
Fig. 8 is a diagram illustrating a UI screen displaying traffic safety information and traffic safety behavior through a user terminal in a block chain-based traffic management system according to an embodiment.
Referring to fig. 8, a1 st-1 st area 811 of a first screen 810 displays traffic safety information indicating that a road ahead is under construction. The 1 st-2 nd area 812 of the first screen 810 displays the target meters that are increased each time the user performs a traffic safety action.
The 2 nd-1 st area 821 of the second screen 820 displays the traffic guidance behavior determined by the roadside apparatus 20 or the server 100. As shown in fig. 8, a plurality of traffic guidance behaviors may be simultaneously displayed, and at this time, a plurality of traffic guidance behaviors may be sequentially displayed in a preferred order. The preferred order between the plurality of traffic guidance behaviors may be determined according to a preset reference or an algorithm. The user may select any one of the plurality of traffic guidance behaviors displayed in the 2 nd-1 st area 821 to drive the vehicle 40 in such a manner that the selected traffic guidance behavior is executed.
As described above, the game is configured in the following manner: that is, the target meters displayed in the 1 st-2 nd area 812 may be cumulatively increased when the user performs traffic safety activities, and the grade is upgraded when the target meters are full. According to one embodiment, the pet may grow when the target meter is full during the game. In FIG. 8, since the target meter displayed in the 3 rd-2 nd area 832 of the third screen 830 is full, the 3 rd-1 st area 831 may simultaneously display the promotion and the graphic indicating the growth of the pet. In addition, when the user fills the target meter, the roadside apparatus 20 or the server 100 may pay the user a bonus award, and the 3 rd-1 st region 831 is displayed with contents prompting the bonus award.
Fig. 9 is a flow diagram for illustrating an embodiment of a blockchain based traffic management system determining traffic safety behavior and providing rewards, in accordance with an embodiment.
Referring to fig. 9, in step 901, the user terminal 50 collects traffic-related data and transmits it to the roadside apparatus 20. In step 902, the roadside apparatus 20 stores the received traffic-related data to the blockchain network together with the location information of the roadside apparatus 20. In step 903, the server 100 determines traffic safety information and traffic safety behaviors corresponding thereto based on the traffic-related data stored in the blockchain network and the location information of the roadside devices. In step 904, the server 100 transmits the traffic safety information and the traffic safety behavior to the user terminal 50. In step 905, the server 100 provides the user terminal 50 with the reward according to the behavior of the vehicle 40 corresponding to the user terminal 50.
As described in the present embodiment, the roadside apparatus 20 or the server 100 determines the traffic safety information and the traffic safety behavior based on the traffic-related data stored in the block chain network and guides the user, so that the user can easily grasp the dangerous situation and know an appropriate countermeasure corresponding thereto. In addition, when the user performs a traffic safety behavior, the roadside apparatus 20 or the server 100 transmits a reward corresponding thereto, so that the user can be induced to drive the vehicle in a preferred direction.
3. Embodiments for recommending routes that avoid traffic congestion based on traffic-related data and providing rewards when a user selects a recommended route
The block chain-based traffic management system according to an embodiment provides a recommended route for avoiding traffic congestion based on traffic-related data stored in a block chain network according to a destination recommended route input by a user, and may provide a reward corresponding to when the user drives a vehicle according to the recommended route. The present embodiment will be described below with reference to fig. 10 to 12.
Fig. 10 and 11 are flowcharts for explaining a method of recommending a route and providing a reward according to route selection by a blockchain-based traffic management system according to an embodiment.
Referring to fig. 10, when the user terminal 50 receives destination information from a user, the user terminal 50 transmits the received destination information to the roadside apparatus 20 together with identification information (e.g., a license plate number, a user name, a phone number, etc.) of the user terminal 50 or the vehicle 40 in step 1001.
In step 1002, the roadside apparatus 20 matches the received destination information and identification information and stores the same in the blockchain network. As described above, the blockchain network may also store traffic-related data collected by at least one of the user terminal 50, the vehicle 40, and the roadside apparatus 20.
According to another embodiment, the user terminal 50 encrypts the identification information and stores the encrypted identification information in the storage unit 54 of the user terminal 50 in step 1001, transmits only the hash value for the encrypted information to the roadside apparatus 20, and the roadside apparatus 20 stores the received hash value in the blockchain network in step 1002. In this way, the identification information including the personal information is securely stored in the user terminal, and the identification information can be certified to be stored in the user terminal by the hash value stored in the tile, so that the reliability of the identification information can be secured.
In step 1003, the server 100 may determine a plurality of candidate routes based on the destination information stored in the blockchain network and the vehicle position corresponding to the identification information matching the destination information.
In step 1004, the server 100 may calculate a traffic congestion degree for each candidate route based on the traffic-related data stored in the blockchain network. In this case, the traffic congestion degree is a value indicating traffic congestion information. The server 100 may calculate the traffic congestion degree according to a predetermined algorithm based on the number of vehicles traveling on each candidate route and the average speed.
In step 1005, the server 100 selects the candidate route with the lowest traffic congestion degree as the recommended route, and transmits the selected recommended route to the user terminal 50 together with at least one other candidate route.
In step 1006, when the user selects the recommended path through the user terminal 50, the server 100 provides the user terminal 50 or the vehicle 40 with an award.
Since the user selects the recommended route provided by the server 100 is considered to contribute to the reduction of the traffic congestion degree, a reward is provided. For example, in step 1005, although there is a route having the shortest distance between the departure point and the destination or a route having the shortest time required to reach the destination among the candidate routes transmitted to the user terminal 50 together with the recommended route, if the user selects the recommended route, it is considered that the user is willing to accept the fuel loss fee or time, and also contributes to reducing the degree of traffic congestion of the road, so the server 100 transmits an incentive corresponding thereto.
When the user leaves the recommended route after selecting the recommended route and driving the vehicle 40, the user terminal 50 requests the server 100 to guide the new recommended route, and the server 100 may determine the new recommended route and transmit it to the user terminal 50. At this time, the server 100 may determine a new recommended path by reflecting traffic-related data additionally collected during the movement of the vehicle 40 from the initial departure point to the current location. The present embodiment will be described below with reference to fig. 11.
Referring to fig. 11, when the vehicle 40, which the user selects the recommended route and drives, leaves the recommended route in step 1101, the user terminal 50 may request the recommended route while transmitting the position information of the vehicle 40 to the server 100. At this time, whether the vehicle 40 leaves the recommended route may be determined by comparing the position measured by the GPS function of the user terminal 50 with the recommended route, or may be determined by comparing the position of the roadside apparatus 20 communicating with the user terminal 50 or the vehicle 40 with the recommended route.
In step 1102, the server 100 determines a plurality of candidate routes based on the destination information corresponding to the user terminal 50 and the current position of the vehicle 40 stored in the blockchain network.
In step 1103, the server 100 calculates a traffic congestion degree for each of the plurality of candidate routes. At this time, the server 100 may calculate the traffic congestion degree in consideration of traffic-related data additionally collected during the movement of the vehicle 40 from the initial departure point to the current position.
In step 1104, the server 100 selects a candidate route with the lowest traffic congestion degree as a recommended route and transmits the recommended route to the user terminal 50 together with other candidate routes.
In step 1105, when the user selects the recommended path through the user terminal 50, the server 100 pays an award to the user terminal 50.
Fig. 12 is a diagram illustrating a state in which a recommended route in consideration of a traffic congestion degree is displayed on a user terminal by the block chain-based traffic management system according to an embodiment.
Referring to fig. 12, two paths 1210 and 1220 are displayed on a screen 1200 displayed by the user terminal 50. It is assumed that the first path 1210 is a recommended path determined in consideration of traffic congestion degree, and the second path 1220 is a shortest distance path. That is, assuming that the second route 1220 has a large number of vehicles and is congested, the first route 1210 has the lowest congestion degree among a plurality of routes from the departure point to the destination.
From the user's standpoint, selecting the second path 1220 can save fuel cost, or save moving time, as compared to the case of selecting the first path 1210. However, if the user prefers to accept these losses and also selects the first path 1210 to help prevent traffic congestion, the server 100 may pay a reward to the user terminal 50.
