Or, it relates to a traffic flow control and traffic safety provision system and method that determines traffic safety, provides accident prevention warnings and guidance, and provides compensation for the contribution of the user's route selection according to the route guidance service to alleviate traffic congestion.

Blockchain technology is a technology that records and stores transactions made over network communications in a reliable and safe way. Blockchain network is a system in a distributed environment that enables the exchange of digitized assets or transactions, and the history of electronic transaction details generated in a peer-to-peer (P2P) network using a shared ledger. Record. Blockchain networks use a decentralized or decentralized consensus mechanism. In particular, all validating nodes on the network approve (or disapprove) the transaction by executing the same (or agreed upon) consensus algorithm on the same transaction. Since the blockchain P2P network uses such a decentralized structure and consensus algorithm, forgery and alteration of transaction details by a third party is virtually impossible, and the reliability and transparency of transaction details can be guaranteed.

Meanwhile, an Intelligent Transport System (ITS) is being introduced to promote efficient road traffic and driver safety and convenience. The technology used in ITS is an advanced traffic management system (ATMS) that analyzes traffic conditions in real time by detecting traffic information such as vehicle characteristics and speed on the road, route selection, estimated travel time, congestion and bottlenecks. ATIS (Advanced Traveler Information System) that provides information such as sections to the driver, sensors and control devices for traffic conditions and obstacle recognition on vehicles are attached to automate driving, and intelligent transportation facilities are installed on the road. It includes the Advanced Vehicle and Highway System (AVHS), which is installed to improve traffic accident prevention and road traffic.

In such ITS, roadside units (RSUs) are installed around roads to detect road conditions and traffic congestion. These devices provide basic data that enables the ITS to operate an efficient traffic system by detecting road conditions, ambient temperature and atmospheric conditions, traffic congestion, and the like using sensors and communication devices.

On the other hand, based on the collected information, the vehicle user identifies his/her current location through a Global Positioning System (GPS) satellite and/or a nearby communication facility, and then displays the location of the vehicle on a digital map.

It is intended to provide a traffic flow control and route guidance system and method that can provide safety information.

Existing services do not provide a means for smoothing the overall traffic flow by resolving such traffic congestion when there are traffic congestion or congested sections. In addition, in the existing navigation route guidance service, even if the user selects an alternative route or a detour route with smooth traffic flow, there is a problem in that it is difficult to motivate the user to select an alternative route because compensation or benefits are not provided to the user.

In addition, the existing service has a problem that the protection and anonymity of personal information generated from users or vehicles are not secured. Therefore, there is a need to provide a system that can control the overall traffic flow smoothly by inducing alternative route selection by overcoming the problems of the existing navigation route guidance service and providing compensation according to the route while protecting users' personal information. have.

In the above-described embodiments, it has been described that the database can be built inside the third node 230 and/or the network 250, but is not limited thereto, and the third node 230 and the third node 230 and the /Or may exist separately outside the network 250. In addition, the database may receive and store traffic-related data periodically or aperiodically from at least one of the third node 230 and the traffic flow control server 260 through a network.

The third node 230 or the traffic flow control server 260 may analyze the traffic condition based on the read traffic related data. For example, the traffic related data may include image data representing road conditions collected by the sensor 340. In this case, the third node 230 may analyze the corresponding image data to determine whether ice is present on the surface of the road. If the third node 230 determines that the current road surface is icing, it may generate a traffic safety message indicating that the road is unsafe and transmit it to the first node 210.

In another example, the traffic flow control server 260 may analyze various traffic conditions, such as predicting a driving time of a vehicle, a dangerous driving section, an accident point, and an accident-prone area. In addition, a desirable action that the vehicle can take in response to the analyzed traffic situation may be determined and provided to the first node 210. In addition, when the first node 210 performs at least one of the recommended predetermined actions, the traffic flow control server 260 may pay the corresponding compensation to the first node 210. The traffic flow control server 260 determines and recommends desirable actions that a vehicle can take in response to traffic safety.

In some embodiments, when a vehicle driver sets a destination, a real-time traffic-related database is analyzed to recommend the shortest route, the shortest time required route, and an alternative route, and for a process of providing compensation according to route selection, FIG. 5 It will be described in detail with reference to.

In some embodiments, the third node 230 may also generate a block including data on the analyzed traffic condition, that is, traffic safety, and data on a desired behavior corresponding thereto. The third node 230 may perform encryption to protect personal information among traffic-related data and store it in an internal storage device (eg, a database), and store the hash value of the encrypted personal information to the first node 210 Can be transferred to.

The first node 210 may display traffic related information and/or predetermined traffic information received from the third node 230 or the traffic flow control server 260 on the display 330. The traffic information displayed on the display 330 may include traffic safety information determined according to a road condition, traffic safety information determined based on information collected from another first node 210, and the like.

5 is a flowchart of a route guidance method according to an embodiment of the present disclosure.

The route guidance method 500 may be initiated with a step (S510) of receiving a destination by a user terminal or a vehicle from a driver. The user terminal or vehicle may be, for example, the vehicle 130 or the user terminal 140 shown in FIGS. 1 to 6. In an embodiment, the user terminal 140 may receive a request for an optimal route and an alternative route for a user's destination, and store input information included in the request for an optimum route and an alternative route in a storage device for each destination. Here, the request for an optimal route and an alternative route may include at least one of information indicating a current location of the user terminal (or vehicle), a GPS signal, and a state of the vehicle. For example, when a user inputs a specific address or location using the user terminal 140 and requests an optimal route and an alternative route, the communication unit 320 may provide a specific address of the user's destination (for example, a city name). , Street name, building name, lot number) may be transmitted to the first node 210.

Upon receiving the request for the optimal route and the alternative route of the destination, the user terminal may transmit the destination and vehicle identification information to the first node (S520). Here, the vehicle identification information is information capable of uniquely identifying the vehicle, and may be any one of, for example, a vehicle number, a driver's name, a phone number, an email address, etc., but is not limited thereto. In one embodiment, referring to FIGS. 1 to 4, the first node 210 may correspond to the roadside device 150, and the first node 210 is installed at a fixed position on the roadside to allow traffic from the vehicle. Related data may be collected, and the collected traffic related data may be provided to the traffic flow control node 260, which is a computing device of a related institution or service institution that may be utilized for traffic flow control and/or route guidance.

In an embodiment, the user terminal may transmit a transaction including vehicle identification information and/or destination self-information to the first node 210. Alternatively, the user terminal may encrypt vehicle identification information and/or destination with a public key and store it in the storage device 350, and transmit a transaction including the hash value of the encrypted information to the first node 210. . In this case, since the user terminal stores and maintains the vehicle identification information and/or the encrypted data of the destination in the storage device 350, it is possible to maintain the security of personal information related to this data, whereas the existence of such personal information Since the first node 210 is recorded in the blockchain network that is stored and maintained, the reliability of this data can also be proved.

After that, the first node may generate a block including the vehicle identification information and the destination (S530). In an embodiment, referring to FIG. 4, the first node 210 may store blocks for recording transactions of traffic related data, and a transaction including traffic related data is provided to the first node 210 or When created, the data is recorded as a block in the blockchain 350. The blockchain 240 generates and stores traffic-related data (or encrypted data) or a transaction including the hash value of the traffic-related data as a block, and the generated block is connected by referring to the hash value of the previous block. The block chain 240 created and maintained in this way may be duplicated and stored in nodes such as the first node 210, the second node 220, and the traffic flow control node 260. In this step, the first node 210 may generate a block including identification information of the vehicle and a destination. Alternatively, the first node 210 may generate a block including identification information of the vehicle and an encrypted hash value of the destination.

In the next step (S540), the traffic flow control node analyzes the traffic congestion based on the traffic-related data of the block chain. In one embodiment, referring to FIGS. 1 to 6, the user terminal 140 and/or vehicle 130 collect various types of traffic-related data in real time while driving on the road, or collect various types of information from the ITS. You can collect it and create a transaction that includes that information. In this case, the first node 210, the position and speed of the vehicle, which is data necessary for determining the optimal route and/or the alternative route, information about the surrounding condition of the vehicle (for example, an image representing the road condition around the vehicle or Traffic related data such as sound information, temperature or weather information, etc.) may be collected through the vehicle 140 and/or the user terminal 150 of a driver driving the vehicle. The first node 210 may generate a block for a transaction including the collected traffic-related data and record it in the block chain 240. When creating a new block, the first node 210 may generate a block for a transaction including the traffic-related data itself, but to protect personal information, the first node 210 may generate a block for a transaction including the traffic-related data itself. You can also create a block for it. In this case, the user terminal or the first node may store encrypted information of traffic-related data in a separate storage device.

In addition, the traffic flow control node may analyze traffic congestion by referring to traffic-related data included in blocks of the block chain recorded by the first node. In an embodiment, when the blocks recorded in the block chain 240 contain traffic-related data itself, the traffic flow control node may analyze the traffic congestion level based on the data. In an alternative embodiment, the traffic flow control node may request traffic-related data from the user terminal or the first node by referring to the encryption hash value of traffic-related data included in blocks recorded in the block chain 240. The user terminal or the first node that receives the request for traffic related data from the traffic flow control node, after verifying the request, retrieves the encrypted traffic related data from the storage device and decrypts the corresponding data with a private key. The user terminal or the first node transmits the decoded traffic related data to the traffic flow control node. The traffic flow control node may analyze traffic congestion based on traffic-related data received from the user terminal or the first node. The traffic flow control node may determine the degree of traffic congestion based on the traffic-related data using the number of vehicles running on the predetermined route, the average moving speed of the running vehicles, and the like.

As described above, the traffic flow control node installs a system capable of detecting traffic information such as characteristics and speed of a vehicle on the road in place of or in addition to the traffic-related data collected by the user terminal to monitor the traffic situation in real time. Automated driving using ATMS system that analyzes and manages, ATIS system that quickly and accurately provides drivers with various traffic information using various communication methods, public traffic information and management system, various high-performance sensors installed in vehicles and roads, and intelligent communication facilities And traffic-related data can be collected through Intelligent Transportation Systems (ITS), including AVHS, which prevents accidents. The traffic flow control node can analyze traffic congestion by using this traffic-related data.

Based on the analyzed traffic congestion level and/or destination, the traffic flow control node may determine route information including an optimal route and/or an alternative route and transmit it to the user terminal (S550). In the present disclosure, the "optimal route" may mean the shortest distance route from the departure point of the vehicle to the destination. Therefore, when the driver of the vehicle selects the "optimal route", when the traffic congestion on the route is not high, it is possible to reach the destination from the starting point using the shortest time or the lowest fuel. On the other hand, the "alternative route" may mean a route having a longer expected driving time or a driving distance than an optimal route among several candidate routes from a vehicle's departure point to a destination, but having a lower traffic congestion. Therefore, when the driver of the vehicle selects the “alternative route”, it may contribute to lowering the overall traffic congestion level than when selecting the optimal route. In one embodiment, the user terminal 140 and/or the vehicle 130 transmits an optimal route and/or an alternative route received from the traffic flow control node 260 through the communication unit 310 to the user terminal 140 and/or It may be output to a navigation device built into the vehicle 130.

When the user selects one of an optimal route and an alternative route output to the user terminal 140 or the navigation device of the vehicle 130, the user terminal 140 or the vehicle 130 receives the selected input and receives the selected input and receives the selected input. 310) may be transmitted to the traffic flow control node 260.

Thereafter, when it is determined by the traffic flow control node 260 that the selection input indicates the selection of one or more alternative routes, a compensation may be paid to the user terminal (S560). When the user's route selection input is an alternative route, the user selects an alternative route that takes more time/cost than the optimal route to help smooth the overall traffic flow, so the traffic flow control node 260 corresponds to Users can be rewarded for contributing to traffic flow control. In one embodiment, the reward paid to the user may be in the form of cryptocurrency recorded and maintained in the blockchain 240 by mining of nodes 210, 220, 230?. In another embodiment, the compensation paid to the user may be in the form of an electronic voucher paid by a government agency or service provider related to the traffic flow control node 240.

6 is an exemplary diagram of a route proposal method and a method of providing compensation according to route selection according to the present disclosure. As illustrated, the vehicle 130 may start driving on a “planned route” based on traffic information and route guidance information provided from the traffic flow control server 110. For example, the driver of the vehicle 130 may start driving on a predetermined route selected from an optimal route and an alternative route provided from the traffic flow control server 110. While traveling on a predetermined route, the vehicle 130 or the user terminal 140 may collect traffic-related data and transmit it to the surrounding roadside apparatus 150. The roadside apparatus 150 may generate a block based on the received traffic-related data and record it in the block chain.

Meanwhile, the traffic flow control server 110 analyzes traffic-related data of blocks recorded in the block chain, generates new optimal route guidance information based on the analysis result, and transmits it to the vehicle 130 or the user terminal 140. I can. In this way, according to the route guidance information updated based on the current traffic-related data in real time, the driver of the vehicle 130 may select and use an alternative route or a detour route that deviates from the predetermined route again.

In one embodiment, the vehicle 130, for example, recognizes that traffic congestion increases on the currently scheduled route, or if the route needs to be changed for other reasons, the route deviating from the existing route (ie, “change route It can be changed to "). In this case, the vehicle 130 may provide traffic-related data to the roadside apparatus 150 on the change route. The roadside apparatus 150 may generate a block based on the traffic-related data received from the vehicle 130 and record it in the block chain.

The traffic flow control server 110 can determine whether there is a change in the traffic flow of the scheduled route by analyzing the traffic-related data of the blocks recorded in the block chain, and the vehicle 130 deviates from the existing scheduled route and uses the changed route. have. For example, the traffic flow control server 110 may measure a change in traffic flow or a change in traffic congestion based on the average moving speed of vehicles on a predetermined route, the number of vehicles running, and the like. If it is determined that the traffic congestion of the scheduled route is reduced due to the use of the change route of the vehicle 130 and contributes to solving the traffic congestion, the traffic flow control server 110 changes the route to the vehicle 130 or its user. It can provide rewards for actions.

In one embodiment of the present disclosure, the traffic flow control server 110 analyzes the traffic-related data of blocks recorded in the block chain, so that the vehicle 130 deviates from the existing scheduled path and uses the change path to determine the change path. It is also possible to further determine whether there is a change in traffic flow. For example, the traffic flow control server 110 may measure a change in traffic flow or a change in traffic congestion based on an average moving speed of vehicles on a predetermined route and a change route, the number of vehicles running, and the like. If it is determined that the use of the change route of the vehicle 130 contributes to the overall reduction of the traffic congestion of the scheduled route and the change route, the traffic flow control server 110 provides the vehicle 130 or its user to the route change action. You can provide a reward for it.

It can be output and provided to the user. Here, the analyzed result may be accident prevention or traffic safety information such as a vehicle deceleration in response to a congested section, but is not limited thereto.

According to some embodiments, the recommendation actions 730 corresponding to the analysis result may be arranged and provided according to a preset ranking or importance. For example, recommended actions of'driving along a recommended route' may be listed as the first priority. A reward that can be obtained when performing the recommendation action may also be paid differently according to the priority or importance of the recommendation action performed by the first node. In the present disclosure, the analysis result and recommendation action 730 are not limited to the examples described above, and various analysis results and various recommendation actions according to each analysis result may be provided.

The user may input a selection of a recommended action provided through a user interface (eg, a touch display, a keyboard, a mouse, a touch pen or a stylus, a microphone, a motion recognition sensor, etc.). In an embodiment, in order to input the selection of the recommendation action, the first node 710 may configure a screen of a preset interface through which the selection can be input and provide the screen to the user through the display 720. As shown in FIG. 7B, the user may input the selection of the recommended action by checking the check box 732 of the recommended action item (for example, driving along the recommended route) to be selected.

After the user of the vehicle inputs the selection of the recommendation action 730, if the action corresponding to the input is performed, the third node may provide a reward corresponding thereto. As described above, the reward value for the recommendation action 730 may be determined in a predetermined manner. For example, the reward according to the recommendation action 730 may be determined according to the importance and ranking of the predetermined recommendation actions. Reward may also be paid from the third node according to a preset method. Here, the reward may be recorded and paid on the blockchain in the form of cryptocurrency, or may be paid in the form of electronic money (or electronic voucher) provided by another institution.

As shown, the reward corresponding to the'driving along the recommended route', which is the first priority in the list of recommended actions 730, is predetermined as '100 coins', and the reward corresponding to the second priority'speed deceleration' is '50. It can be decided to be paid after being decided larger than the coin'in. The reward obtained by performing the recommendation action 730 may be provided through the display 720 of the first node 710. In an embodiment, the acquired reward may be visually displayed on the screen of the display 720. For example, the gauges 740 and 742 for compensation are provided on the screen of the display 720, so that the user can visually check the compensation obtained so far. Here, the gauges 740 and 742 may increase in proportion to the acquired compensation, and represent the accumulated amount of compensation acquired by the user according to the behavior in response to traffic safety up to the present time. For example, due to the reward obtained by performing the recommendation action by the user, the gauge 742 shown in FIG. 7(b) may be displayed as an increase compared to the gauge 740 shown in FIG. 7(a). have.

As described above, the traffic safety providing system of the present disclosure may analyze a traffic-related situation based on the traffic-related data collected from the first node 710 and recommend a predetermined action appropriate for the situation. In addition, when the first node 710 or the vehicle performs a recommended act, it is possible to induce a recommended act that can contribute to traffic safety by paying compensation for it, thereby maintaining a smooth traffic flow and driving the road. The safety and convenience of the driving driver can be promoted.

In one embodiment, when the first node 710 achieves a preset goal, the first node 710 may receive an additional reward from the third node. Specifically, when the compensation received from the third node is accumulated and has a value equal to or greater than the preset target value 750, the third node may pay the additional compensation 760 based on the accumulated compensation value. Here, the accumulated compensation value is a block by which the third node checks the compensation value information of the previous first node by referring to blocks of the block chain based on the identification information of the first node, and adds additional compensation to the confirmed compensation value. Write to the chain so that it can be served to the first node.

Whether the cumulative value of the compensation acquired by the first node has achieved the target value 750 is as shown in FIG. 7(c), for example, a full gauge displayed on the display 720 ( 746). In this case, the third node may additionally provide a reward 760 corresponding to achieving the target value, such as'coin bonus 5%' and'experience value added 3%', based on a predetermined method or rule.

In an embodiment, the analysis result and recommendation behavior by the third node may be provided in the form of a game for fostering pets. As shown in Fig. 7(c), when the gauge 746 is full to 100%, a young animal (eg, a chick) corresponding to the current level through level up is a mature animal corresponding to the next level ( For example, it can grow as a chicken), and with the level-up reward 760, the third node can provide additional rewards such as'coin bonus 5%' and'experience value additional 3%'. In this way, by providing the analysis result and recommended behavior by the third node in the form of a game, it is possible to give motivation and interest to the user to actively perform the behavior that can contribute to traffic safety.
