BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent transportation system (ITS), and more particularly to an intelligent transportation system based on road reservation, which can reduce costs by providing various advantages to users to reserve roads for use by the user. It is about.

In recent years, due to the increase in population and the absolute increase in traffic volume, it is difficult to move smoothly and maintain traffic conditions simply by increasing the amount of roads.

Accordingly, an intelligent transportation system has been proposed as a method for optimizing road use by using and combining road and vehicles with advanced information and communication technology to realize safe, comfortable and efficient traffic. Such an intelligent traffic system includes a vehicle navigation system (CNS) including heading, direction, map information, and voice commands, a command function in the vehicle navigation system, vehicle location, and logging. The vehicle tracking system (AVLS), and the current intelligent transportation system (ITS) including automatic vehicle information determination in the vehicle navigation system, have been evolved.

Today's intelligent transportation systems include Advanced Traffic Management System (ATMS), Advanced Travel Formation System (ATIS), Advanced Vehicle and Highway System (AVHS), Advanced Public Transportation. It offers five services: Advanced Public Transportation System (APTS) and Commercial Vehicle Operation (CVO).

Hereinafter, the present invention will be described in detail with reference to the drawings.

First, the conceptual part of this invention is demonstrated. TECHNICAL FIELD The present invention relates to an intelligent transportation system, and in particular, a method and system for using the Internet and wireless communication technology in an intelligent transportation system (hereinafter, ITS based on road reservation) in order to reduce the high cost of building an intelligent transportation system. (Called a system) will be described.

The present invention provides a method for efficient road management by predicting / adjusting the traffic volume for each road time by reserving roads to be directly driven by drivers using roads. In addition, drivers who have reserved a road for their driving and actually used the reserved road accumulate corresponding points in proportion to the length of use of the road and the communication fee required for reservation, and provide various benefits using this point. . Further, in order to induce the driver's active cooperation, the more detailed the waypoint between the starting point and the destination is provided, the more the means for issuing the number of electronic lottery tickets is provided. It also points to the number of times a driver has visited a traffic control center to book a road use or provide information about an accident that may be disrupting road traffic, offsetting penalties imposed for violations of road traffic laws. It also provides services.

1 shows a schematic diagram of an ITS system based on road reservations according to the present invention.

The driver connects to an ITS system center (hereinafter referred to as ITS system 100) based on a road reservation according to the present invention and reserves a road to use. The methods of reserving roads or providing information on accidents that cause road disruptions can be broadly divided into how to use the Internet, how to use a telephone or ARS service, and how to use mobile communication terminals (PCS phones, CNS terminals, etc.). There is a way to use it.

When the driver reserves a road for the driver to use one of the above methods, the ITS system center 100 processes this data to provide the driver with possible routes and optimal routes, road reservation status, and estimated time required. .

When it is time for the driver to use the actual road, or when the driver transmits a signal to the ITS system center 100 to notify the start of the road through the mobile communication terminal (cell phone, PCS phone) or the CNS terminal, the ITS system center 100 The driver's position tracking unit 600 commands the driver's position. In addition, the driver location tracking unit 600 tracks the movement route of the vehicle to determine whether the reserved road is used.

As a result, when the driver used road reservations and reserved roads. As a reward for this, points and electronic lottery tickets are provided according to the driver's performance. This point varies in proportion to the length of the road used by the driver and the communication fee used, and the number of electronic lotteries depends on the number of waypoint inputs. These points and the electronic lottery ticket are provided in correspondence with the ID to be connected, and the electronic lottery ticket is transmitted to an e-mail registered when the driver receives the ID from the ITS center.

In addition, the points received by each driver is converted into cash and paid to the driver through a PCS, a cellular phone, and a smart card terminal, and can be used anywhere in a group or a place supporting the service according to the present invention.

2 is a diagram illustrating a configuration of an ITS system center 100 according to the present invention.

The ITS system center 100 includes a road reservation unit 200, an ID management unit 300, a point management unit 400, an electronic lottery management unit 500, a driver location tracking unit 600, a database 701, 702, and an email interface. 800, a smart card interface 900, and a CNS / wireless network interface 1000.

The road reservation unit 200 is a part that processes and manages all data related to road reservation. The road reservation unit 200 includes a possible route calculation module 201, an optimal route selection module 202, and a route display module 203.

The possible route calculation module 201 calculates a possible route based on the starting point, the destination, and the waypoint entered by the driver. Possible route calculations are performed based on the point and link data stored in the database 701. The point and link data may be used by converting the GIS data. Each point becomes one node on the road shown on the electronic map, and the link is the smallest path on the road from one point to another. The more granular the point and link information is, the more accurate the route, or more possible routes can be calculated. In this case, the calculated possible path data is transmitted to the optimum path selection module 202.

The optimal path selection module 202 calculates the time required for each of the possible paths based on the link state data for each link stored in the database 710 to select the optimal path. The road condition data for each link is composed of each link and time zones that affect the reservation status of each link, whether there is an accident and road construction, and the speed of the road. It will automatically search for the best possible route available. Searching for the best route in the best route selection module 202 means searching for a route that can reach the destination in the shortest time, and considers that the route can be the shortest distance in the road condition. In certain cases, it is possible to build a database in which a driver can select a stable road in consideration of a case where a driver moves a special patient.

The route display module 203 extracts display data to be transmitted to the client based on the data. That is, the map data screen and various data to be provided to the driver are extracted from the database 710 by the map 710 for the route and the point designated by the possible route calculation module 201 and the optimal route selection module 202, and are transmitted to the client. In particular, the route display module 203 modifies the data format to suit the medium from which the driver obtains road information at the time of reservation or actual driving. That is, if the driver uses the CNS terminal, the format is supported by the CNS terminal, if the driver is using the PCS terminal, the format is represented by the character through the PCS terminal, or if the driver is used by the PC application format. Simultaneously change the role.

The ID manager 300 performs an ID registration procedure when a new driver first accesses the system, and stores / manages / updates the driver's ID.

The point manager 400 calculates the length of the road to be used by the driver based on the point and link data based on the starting point, waypoint, and destination information input by the driver and stores it as points for each driver. These points are stored for each driver, and are temporarily stored when the driver makes a reservation, and the points are directly added only when the road is used in a state reserved by the driver.

The points earned in this way can be used to receive various beneficial benefits from the inventors and service operators. For example, when converting cumulative points to replace highway tolls with cash stored in IDs, offsetting penalties and cumulative points for violations of traffic laws, exempting some penalties, or paying car taxes or car insurance premiums. There may be benefits and convenience to the driver in various forms, such as using part of it or paying part of it when paying for parking in a public parking lot. In this case, the points obtained by the driver are stored as an amount available for the driver's ID using a wireless communication terminal or a smart card terminal, and the driver may enjoy various benefits using this at any time. The wireless communication terminal and the smart card interface 900 determine contents to be recorded in the smart card, and when the payment is actually requested by the wireless communication terminal and the smart card terminal, the wireless communication terminal and the smart card interface 900 transmits points and points converted in points of the driver's ID. It is an interface for wireless communication with a wireless communication terminal or a smart card terminal. In the present invention, it is collectively referred to as an interface including both a software configuration and a hardware configuration.

The electronic lottery management unit 500 determines the number of electronic lottery tickets based on the number of stops entered by the driver and stores the number of electronic lotteries once for each driver, and then the electronic lottery ticket is registered by the driver only when the driver uses the road as reserved. Is sent. Thus, when the electronic lottery ticket sent by the driver's e-mail is won, the winning information is automatically received and the prize money is automatically converted into cash and deposited into the driver's account number. The e-mail interface 800 functions to calculate an e-mail address first input by the driver from ID data and send an electronic lottery ticket to the e-mail.

The driver location tracking unit 600 is a means for monitoring whether the driver has moved the road as reserved. There are a number of implementation methods for implementing the subsystem of the driver and the means for monitoring the movement path of the vehicle. For example, a CNS terminal or a PCS phone with GPS support can be used. They all have something in common to support the GPS system. In other words, it has the function of finding the location of the terminal through the GPS system and transmitting it to the central center. The location of the terminal transmitted to the central center is transmitted and received through the CNS / wireless network interface 1000.

The CNS / Wireless network interface 1000 is a terminal through a wireless communication network with the ITS system center 100 according to the present invention when the driver reserves a road, informs the actual use of the road, or detects the location of the driver. Interface for communication with (CNS terminal or PCS terminal). The interface in the present invention refers to all software / hardware components for communication and information transmission and reception between the ITS system center 100 and the wireless communication network according to the present invention.

3 is a flowchart illustrating a road reservation process according to the present invention.

The driver connects to the ITS system center 100 according to the present invention, and inputs a departure point, an arrival point, a stopover point, and a departure time at which the driver starts (steps 301 to 306).

As a first method of making a reservation, a procedure in which a driver accesses the ITS system center 100 via the Internet using a PC and reserves a road will be described.

When accessing the web site, enter the user's ID before connecting. If the driver does not have an assigned ID, register a new ID. If you receive an ID, be sure to include your e-mail address and your mobile phone number in the driver's history.

When the driver accesses the site, a road reservation screen is provided, which is roughly divided into two areas: a map screen and a text area for entering a starting point, an arrival point, a stopover, and a departure time. The driver may select and input a point of each region provided in the road reservation screen in the text area, or input the correct point by clicking the map screen.

The first time you enter a point in the text area, you can select it in a top-down manner. In other words, if the driver selects the city at which the driver is located, the city / county of the city is provided as text in the sub category, and if the city / count is selected, the city / surface of the city / country is provided as the text as the sub-category do. Then, finally, the corresponding road or point is provided as text. When the user clicks on this point, it is input to each of a starting point, a destination, and a waypoint.

Secondly, when each point is selected on the map screen, when the corresponding point is selected while reducing and enlarging the map screen, a starting point, an arrival point, and a waypoint are registered. At this time, the map data can be linked with the currently built GIS system and can be serviced through an independent DB displaying only roads. In particular, in the case of interworking with the GIS system, the map shown on the screen of the user may provide the same environment as the actual road.

In this case, if the driver inputs a waypoint in detail, an electronic lottery ticket is provided for each additional waypoint in order to provide an advantage as the entry point is entered. That is, when the driver provides five waypoints, five electronic lotteries are delivered to the user. Of course, such an electronic lottery is made after confirming that the road actually reserved by the driver is used.

As a second method of making a reservation, the driver reserves a road through a wired or wireless telephone. In this case, the driver connects to the ITS system center 100 according to the present invention through a voice telephone. When the ITS system center 100 is accessed through a voice telephone, the reception person directly inputs the information spoken by the driver through the Internet. Of course, in this case, all the information is input through the dialogue between the driver and the reception representative. In this case, points are temporarily accumulated according to the communication time used by the driver, and when it is determined that the road actually used is reserved, the points are actually added to the driver's ID.

A third method of making a reservation is a method of making a road reservation through a wireless communication terminal. Examples of wireless communication terminals include CNS terminals and PCS terminals.

In the case of a PCS terminal, the service is provided by a PCS service provider. If the road reservation function is selected on the screen of the terminal, the road reservation can be made through communication with the PCS server. In this case, it is possible to make a reservation by the letter-type top-down method in the case of a PC as a current character.

In the case of the CNS terminal, when the button of the road reservation is pressed, the map information is displayed, and the reservation is made in the same manner as in the PC.

Next, the server receives the data and processes the data (steps 307-308).

When the driver clicks the button of reservation completion on the client's web page, the driver's ID, starting point, destination, waypoint and departure time are data and transmitted to the server. Each component in the server then processes this data.

The possible route calculation module 201 calculates a possible route based on the starting point, the destination, and the waypoint entered by the driver, and transmits the possible route to the optimal route selection module 202. Then, the optimal route selection module 202 calculates the required time of each of the possible routes based on the road condition data for each link and selects the optimal route. The road status DB for each route stores elements that affect the reservation status for each route, whether there is an accident and road construction, and the road speed for each route, and based on these data, the optimal route selection module 202 can use the driver. It will automatically search for the best possible route.

Then, the path display module 203 extracts the display data to be transmitted to the client based on the data, converts the display format to match the request terminal, and transmits the display data to the client.

On the screen of the client, the possible route, the optimum route, the estimated time, etc. are displayed along with the map data, and the main road status information is also displayed. The user can arbitrarily select among these possible paths and optimal paths. When the user selects the final route, the data is sent to the server to make a road reservation (step 309).

At this time, if the means for the driver to access the ITS system center is a wired or wireless telephone, the method further includes accumulating communication charges as points (steps 310 to 313).

4 illustrates a procedure of the ITS system according to the present invention for determining whether a reserved driver actually used a road, and a procedure for an advantage granted to the driver in actual use.

Steps 401 to 405 described in FIG. 4 have been sufficiently described in the description of FIG. 3, and thus description thereof will be omitted.

The driver location tracking unit 600 is a means for monitoring whether the driver has moved the road as reserved. There are a number of implementation methods for implementing the subsystem of the driver and the means for monitoring the movement path of the vehicle.

First, a car navigation system (CNS) terminal is an example. The CNS terminal has a built-in GPS receiver to determine the location of the vehicle in real time, and transmit the location of the vehicle to the CNS control center through a wireless antenna. The driver's position tracking unit 600 of the ITS system center 100 according to the present invention receives and processes the data, thereby accurately determining the position of the driver's vehicle.

Another method is to use a personal mobile communication (PCS) terminal, which is used by most drivers. Currently, since mobile phone operators are providing location information checking services using PCS terminals, the mobile phone operators can easily identify a user's location by interworking with these services and the user location tracking unit according to the present invention.

In addition, it is also possible to implement this by using TRS or by adding wireless communication technology to PDA and HPC.

In either case, these examples are intended to pinpoint the location of the driver and the vehicle, and can be anything if only the location of the driver and the vehicle can be pinpointed.

After extracting the ID of the road reservation user for each time zone, the driver location tracking unit 600 according to the present invention first determines whether a time reserved by a specific driver of a specific road is reached (step 406), but the driver does not have a reservation time. It is determined whether a road use start signal has been sent (step 407). As a result of this determination, when the driver's reservation time is reached or when the driver sends a road use start signal, the position of the driver and the vehicle is monitored.

The way for the road reservation system to notify the road reservation system 100 of the road use is a method using a CNS terminal capable of supporting the road reservation function and the road driving function according to the present invention, and using a wireless communication terminal (PCS phone). There may be a way to notify the person in charge of the reception center directly. At this time, the positions of the CNS terminal and the PCS phone can be automatically determined (steps 408 and 409).

In this case, it is determined whether the determined position of the driver or the vehicle is a starting point reserved by the driver, or a possible route and an optimal route (step 410).

At this time, if the driver is neither on the starting point nor on the route, the driver assumes that the reserved road has not been used and cancels the electronic lottery release and the temporary accumulation point (step 414).

If it is on the route, the ITS system center 100 recalculates the possible route and the optimum route in consideration of the change in the road environment due to the difference between the reservation time and the actual use time. At this time, if the rerouted route matches the route at the time of reservation, it is displayed as it is, but if it does not match, information is transmitted to each terminal so that the driver can see it (step 411). In the case of the PCS terminal, a voice service or a text message service may be used, and in the case of the CNS terminal, the changed route may be directly displayed on the terminal screen.

If the driver continues to monitor the driver's location and the driver's location becomes the same as the destination, it is determined that the driver has arrived at the reserved destination (step 412), and the user is given the points and the electronic lottery given to the driver at the time of the road reservation, and the jackpot as a bonus. (Step 413). In this step, the time for monitoring the position of the driver may vary according to various circumstances for each time zone according to the road condition. In other words, the monitoring cycle can be increased at a time when the road condition changes rapidly, and at a time when the road condition changes slowly.

Although the ITS system 100 according to the present invention has been described by way of example, the above embodiment merely provides means that can be implemented and should not be construed as limiting the scope of the present invention. The scope of rights according to the invention should be defined by the claims below.

According to the ITS system according to the present invention, by directly booking the road to be used by the driver using the Internet and wireless communication network, the astronomical hardware cost used to build the ITS system can be significantly reduced, and the efficiency of road use can be improved. It has the advantage of being able to.

According to the ITS system according to the present invention, it is possible to reduce the cost of building an intelligent transportation system by reducing various hardware devices existing under the advanced traffic management system by pre-booking road use.
