According to the present invention, in a simulation system that implements a realistic road environment and traffic volume, traffic problems such as traffic congestion and collision between vehicles are not simulated together, thereby preventing the user's activity from being restricted, thereby further increasing interest in the simulation system. The present invention relates to a traffic simulation system and method that can cause a lot of traffic.

As today's well-known PC (Personal Computer) is widely used and the field of computer graphics (CG) is further developed, simulation is being widely used to model and perform a virtual phenomenon or event in reality. Simulation not only saves time and money, but also allows you to perform virtual tests (experiments) that you can't do in real life, and it's also used in games of various genres.

As such, the most important thing in a simulation system as a means of learning, as well as means of learning, indirect experience, and academic research is realism above all. Therefore, in the simulation system, the overall parameter values and rules are similar to reality, and by applying CG techniques such as rendering, a more realistic feeling can be obtained.

However, for simulation systems that control road environment information and traffic volumes (parameter figures) that are similar to reality, and vehicles that drive through traffic controls (rules) that are similar to reality, traffic congestion and collisions between vehicles due to realistic parameters and rules Realistic problems such as and the like are simulated together, resulting in problems such as limited user activity and reduced interest.

Accordingly, in a simulation system that realizes a road environment and traffic volume similar to the reality, there is a demand for a technology that continuously induces user interest by maximizing realism while preventing traffic problems such as traffic jams and collisions between vehicles.

The present invention has been made to solve the above problems, in the simulation system that implements the road environment and the traffic volume similar to the reality, the traffic problems such as traffic congestion, collision between vehicles is not simulated together, the user's activity limit And a traffic simulation system and method that prevents a decrease in interest.

In addition, an object of the present invention is to provide a traffic volume simulation system and method that facilitates the search and acquisition of information on the traffic volume distribution and traffic congestion area in the real world.

In addition, the present invention provides a traffic volume simulation system and method that makes it easy to grasp the distribution changes of the traffic volume and congestion situation expected when the road environment information and signaling system is modified in reality, thereby increasing the efficiency of the traffic policy change. It aims to provide.

In addition, an object of the present invention is to provide a traffic volume simulation system and method that enables traffic-related learning more efficiently, such as road driving practice simulation.

In order to achieve the object of the present invention as described above, the traffic simulation system according to the present invention, the traffic allowance calculation means for calculating the traffic allowance for each road section, using the number of lanes and the prescribed speed extracted from a predetermined database And proper traffic calculating means for calculating proper traffic traffic for each of the road sections based on the calculated traffic allowance, and a moving route of the vehicle to drive the road sections while maintaining the calculated proper traffic traffic. And determining route means for causing the vehicle to be simulated with the determined movement route.

In addition, the traffic simulation method according to an aspect of the present invention, using the number of lanes and the prescribed speed extracted from a predetermined database, calculating the traffic allowance for each road section, and based on the calculated traffic allowance, Calculating a suitable traffic traffic for each of the road sections, and determining a moving route of the vehicle to drive the road sections while maintaining the calculated appropriate traffic traffic, such that the vehicle is simulated with the determined moving route. It includes a step.

Hereinafter, a traffic simulation system and method according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a traffic simulation system according to an embodiment of the present invention.

The traffic simulation system 100 may be composed of a traffic allowance calculation means 120, a proper traffic calculation means 130, and a route construction means 140.

The traffic allowance calculating unit 120 calculates a traffic allowance for each road section by using the number of lanes and the prescribed speed extracted from the predetermined database 110. That is, the traffic allowance calculation unit 120 serves to calculate a traffic allowance capable of dispersing traffic in optimal conditions for each road section provided for the simulation.

In order to calculate the traffic allowance, the database 110 maintains information on the number of lanes, the prescribed speed, and the like for each road section, and the traffic allowance calculation unit 120 provides information on a specific road section from the database 110. Then, the traffic allowance in each road section is calculated by various methods using these information.

For example, when the information about the width and length of the vehicle and the holding distance between the vehicles is set in advance, the traffic allowance calculating unit 120 may be allowed maximum when the vehicle is stopped in the first lane of each road section. Calculate the number of vehicles present. Thereafter, the traffic allowance calculation unit 120 compares the calculated number of vehicles with the number of vehicles in the number of lanes extracted from the database 110 and, in addition, the number of vehicles in each road section traveling at the specified speed in the lanes. By calculating the traffic allowance for each road segment can be calculated.

As described above, the database 110 stores information on road sections on which the vehicle runs in the traffic simulation system 100 of the present invention, in particular, the number of lanes of each road section, and prescribed speed information to be kept in each road section. Save it.

The database 110 may further include information about the traveling vehicle under control of the traffic simulation system 100, for example, the width and length of the vehicle, the determined movement route of the vehicle, the driving state of the vehicle, and the current position of the vehicle. It may further include information and the like. That is, the database 110 may serve as a storage of values used in the calculation of the movement route calculation of the vehicle, the calculation of the expected movement route of the external vehicle, the calculation of the distance between the movement routes of the vehicle, etc. by maintaining such information.

As illustrated in FIG. 1, the database 110 may be installed in a server (or external storage) connected to a communication network to transmit road environment information and vehicle information to the traffic simulation system 100 at a request or at regular intervals. It may be installed in a form that is further included in the traffic simulation system 100 of the present invention.

The appropriate traffic calculating means 130 calculates the appropriate traffic traffic for each of the road sections based on the traffic allowance calculated by the traffic allowance calculating means 120.

That is, the proper traffic calculating means 130 calculates the appropriate traffic traffic so as to have as much traffic as possible within the range that each road section can accommodate by utilizing network flow logic. The network flow logic may relate to maximizing the flow (flow) that can go from any vertex to any other vertex within a range that does not cause backflow beyond the capacity that a given edge can accommodate.

In addition, the appropriate traffic calculating means 130 may calculate the appropriate traffic traffic corresponding to the state of each of the road sections based on the traffic allowance calculated by the traffic allowance calculating means 120.

The route construction means 140 determines the movement route of the vehicle to drive the road sections while maintaining the calculated appropriate traffic traffic in the appropriate traffic calculation means 130, thereby allowing the vehicle to be simulated with the determined movement route. . That is, the route construction means 140 plays a role in configuring the movement route of the vehicle such that the traffic volume in each of the road sections is distributed within the calculated appropriate traffic traffic.

In this case, in the traffic simulation system 100 according to the present invention, each road section may be composed of at least one of an intersection section, a comparison lane section, or an alley section, and the route constructing unit 140 includes the intersection section and the comparison. By alternately repeating the lane section n times, a plurality of consecutive straight lines may be combined to determine the movement route of the vehicle.

2 is a view for explaining an example of configuring a moving route of the vehicle in the traffic simulation system according to an embodiment of the present invention.

In FIG. 2, reference numerals 220, 230, 240, 250 denote intersection sections, and reference numerals 201, 202, 203, 204, 205, Reference numerals 206, 207, 208, 209, 210, 211, and 212 may refer to a comparison lane. The traffic simulation system 100 of the present invention moves to a vehicle 260 to be simulated by using traffic allowances and appropriate traffic traffic of each road section 200 similar to the reality consisting of the intersection section and the comparative lane section. Route 270 can be determined.

The vehicle 260 of FIG. 2 travels along the initially determined movement route unless the state of the road sections 200, for example, the number of lanes, the prescribed speed, etc., is reset, and thus the traffic simulation system 100 of the present invention. In FIG. 3, a vehicle 260 driving along the movement route 270 may be recognized as a simulation vehicle.

On the other hand, there may be a vehicle traveling a road section without a predetermined movement route, and the traffic simulation system 100 of the present invention may further include a route determination means 150 to identify such a vehicle.

That is, the route determining means 150 determines whether there is a movement route determined for each vehicle. As a result of the determination by the route determining means 150, when there is no moving route, the route configuring means 140 recognizes the vehicle as an external vehicle.

The external vehicle of the present invention is operated by a general user (for example, a game player) or an external server connected to the traffic simulation system 100 of the present invention, and the above-described simulation vehicle (the traffic simulation system 100 of the present invention). In contrast to a vehicle in which a movement route is determined), the vehicle may refer to a vehicle in which an accurate movement route cannot be determined.

For such an external vehicle, the route constructing unit 140 may determine an optimal expected movement route using at least one of a current position, a moving direction, or a moving speed recognized as the external vehicle. At this time, by predicting that the external vehicle will travel the determined movement route, the traffic simulation system 100 of the present invention induces a smooth traffic volume by adjusting the simulation vehicle.

In addition, under the control of the route determining means 150, the route configuration means 140 updates the determined estimated movement route at regular time intervals, thereby increasing the accuracy of the expected movement route of the external vehicle and interacting with the simulation vehicle. Makes this possible.

In addition, the traffic simulation system 100 of the present invention may add a function for preventing a collision between the vehicles being simulated, and further include a collision estimation means 160 to prevent such a collision of the vehicle. Can be.

That is, the collision predicting means 160 may determine whether a collision between the vehicles is expected by using the determined distance between the movement routes of the respective vehicles.

The collision estimating means 160 configures the movement route of each simulation vehicle as a series of line segments of the two-dimensional plane analysis geometry, and then calculates the distance between the movement routes by an analysis geometry method to consider the width, length, and direction of the vehicle. For example, collisions between simulated vehicles can be expected. In addition, the collision estimation means 160 may predict the collision between the simulated vehicle and the external vehicle by calculating the distance between the moving route and the point in the plane analysis geometry by the method of the analysis geometry and considering the width, the length, and the direction of the vehicle. have.

As a result of the determination by the collision predicting means 160, when a collision between the vehicles is expected, the route configuration means 140 changes the movement route of the vehicle (simulation vehicle) or prevents the vehicle from colliding with the vehicle. The vehicle is set to at least one of a pause state, a deceleration state, and an acceleration state to prevent collision between vehicles.

For example, when a collision is anticipated according to the determination of the collision predicting means 160, the route construction means 140 pauses a vehicle traveling far away in the distance from the expected collision position after a predetermined distance, and from the expected collision position. The collision between the vehicles can be prevented by continuously driving a vehicle traveling near a distance or by temporarily accelerating driving. As another example, when a collision is anticipated according to the determination of the collision predicting means 160, the route configuration means 140 may determine the determined movement route or the expected movement route of the vehicles expected to collide in consideration of the traffic allowance and the appropriate traffic traffic. You can also reconfigure.

The collision avoidance method may be selected or randomly determined by the route configuration means 140 under the control of the collision prediction means 160 in consideration of each situation in which collision between vehicles is expected. have.

In addition, the traffic simulation system 100 of the present invention may add a function for stopping all vehicles being simulated around the intersection in case of emergency, and all red time setting means 170 for preventing the entry of such vehicles at the intersection. ) May be further included.

That is, the all red time setting means 170 serves to prohibit entry of the vehicle into the intersection section and to set a predetermined time for continuing the vehicles that have already entered the intersection section.

At intersections, traffic in different directions tends to be congested. To solve this problem, the all-red time setting means 170 sets an all-red time that prohibits entry of the intersection section of vehicles in all directions as a rule for eliminating traffic congestion in the intersection section. That is, the all-red time setting means 170 prevents the further entry of the vehicle to the intersection section during the set all-red time, and induces traffic congestion in the intersection section to be resolved by continuing only the vehicles that have already entered.

3 is a view for explaining all-red time setting means for solving the traffic congestion in the intersection section in the traffic simulation system according to an embodiment of the present invention.

As shown in the figure, when traffic congestion occurs in the intersection section 300 in which the vehicle can travel in the E↔W direction and the S↔N direction, the all red time setting means 170 may set a predetermined time. .

Under the control of the all red time setting means 170, the route construction means 140 is configured to enter the intersection section 300 during the set all red time, in which the vehicle 301 and 302 in the E → W direction, W → Vehicles 311 and 312 in the S direction, vehicles 317 and 318 in the S → N direction, and vehicles 315 and 316 in the N → S direction can be temporarily stopped. At the same time, the route constructing unit 140 is configured to move the vehicles 305, 306, 307, and 308 that have already entered the intersection section 300 out of the intersection section 300, 303, 304, 309, 310, 313, 314, 319, and 320 are driven along the moving direction in each road section, thereby inducing traffic congestion in the intersection section 300 to be eliminated.

4 is a flowchart illustrating a procedure of a traffic simulation method according to an embodiment of the present invention.

First, the traffic volume simulation system 100 extracts road segment information such as the number of lanes and a prescribed speed from a predetermined database through the traffic allowance calculating unit 120 in step S410, and the road segment information in step S420. Calculate the traffic allowance for each road segment using.

In addition, the traffic simulation system 100 uses information on each road section, such as the number of lanes and a prescribed speed, received or retrieved from the database 110 according to the operation of the traffic allowance calculation unit 120, and information on a vehicle driving. The traffic allowance in each road segment can be calculated in various ways. For example, the traffic allowance calculation unit 120 is the maximum number of vehicles that can be allowed when the vehicle is stationary in the first lane of each road section when the width and length of the vehicle and the maintenance distance between the vehicles are given in advance. Can be calculated. Therefore, from the calculated number of vehicles, the number of vehicles in the number of lanes extracted from the predetermined database 110 can be calculated, and also, the number of vehicles in each road section traveling at the specified speed, that is, the road section The traffic allowance for each can be calculated.

The database 110 includes information on road sections on which the vehicle travels in the traffic simulation system 100, in particular, the number of lanes of each road section, and prescribed speed information to be observed in each road section. In addition, the database 110, the control of the traffic simulation system 100, the information about the traveling vehicle, for example, the width and length of the vehicle, the determined movement route of the vehicle, the driving state of the vehicle and the vehicle The current location information may be included, and the database 110 may also serve as a storage of values used in the calculation of a moving route of the vehicle, an expected moving route of an external vehicle, or a distance between the moving routes of the vehicles. do.

The database 110 may be installed in a server (or external storage) connected to a communication network, and transmit road environment information and vehicle information to the traffic simulation system 100 when requested or at regular intervals. The simulation system 100 may be further included and installed.

Next, the traffic simulation system 100 calculates appropriate traffic traffic for each of the road sections based on the traffic allowance calculated through the appropriate traffic calculating means 120 in step S430.

In other words, the appropriate traffic calculating means 130 is a network flow logic that maximizes the flow (flow) that can go from one vertex to another within a range that does not cause backflow exceeding the capacity that some edges can accommodate By utilizing, the appropriate traffic traffic can be calculated based on the traffic allowance so that each road segment has as much traffic as possible within an acceptable range.

In step S440, by determining the movement route of the vehicle to drive the road sections while maintaining the calculated appropriate traffic traffic, the vehicle is simulated with the determined movement route.

The route constructing unit 140 may configure a movement route of the vehicle such that the traffic amount in each of the road sections is distributed within the calculated appropriate traffic traffic.

In this case, in the traffic simulation system 100 according to the present invention, each road section may be composed of at least one of an intersection section, a comparison lane section, or an alley section, and the route constructing unit 140 includes the intersection section and the By alternately repeating the section of the comparison lane n times, a plurality of consecutive straight lines may be combined to determine the movement route of the vehicle, as shown in FIG. 2.

5 is a flowchart illustrating a procedure of a method for determining an expected movement route of an external vehicle in a traffic simulation system according to an embodiment of the present invention.

The traffic simulation system 100 may determine whether there is a movement route of the vehicle driving through the route determining means 150 in step S510.

As a result of the determination in step S510, when there is no moving route of the vehicle being driven, the route configuring means 140 may recognize the vehicle as an external vehicle under the control of the route determining means 150. (S520).

The external vehicle of the present invention is operated by a general user (for example, a game player) or an external server connected to the traffic simulation system 100 of the present invention, and unlike the simulation vehicle, an accurate movement route cannot be determined. It can be a vehicle.

In operation S530, the route configuring means 140 may determine the expected movement route using at least one of the recognized current position, the movement direction, or the movement speed of the recognized external vehicle under the control of the route determination means 150. .

The traffic simulation system 100 of the present invention can simulate a smooth traffic volume by adjusting the simulation vehicle while the external vehicle travels the expected movement route.

After a predetermined time has elapsed (S540), it is determined whether the information on the external vehicle (current position, movement direction or moving speed of the external vehicle) used to determine the expected movement route is changed (S550). In this case, the route configuring means 140 may update the determined expected movement route under the control of the route determining means 150 (S560).

Alternatively, when a predetermined time elapses (S540), the route configuring means 140 may update the determined expected movement route regardless of whether information on the external vehicle is changed (S560).

If the predetermined time has not elapsed in step S540, the information on the external vehicle has not changed in step S550, or the update of the expected movement route is completed in step S560, the route configuring means. 140 moves back to step S540 and waits for a predetermined time to elapse.

6 is a flowchart illustrating a procedure of a method for preventing a collision between vehicles in a traffic simulation system according to an embodiment of the present invention.

The collision estimation means 160 of the traffic simulation system 100 may calculate the distance between the movement routes of the vehicle in step S610.

In operation S620, the collision estimation unit 160 may determine whether a collision between the vehicles is expected using the calculated distance between the movement routes of the vehicles.

When the collision predicting means 160 predicts a collision between simulation vehicles, the collision prediction means 160 configures a movement route of each of the simulation vehicles as a series of line segments of a two-dimensional plane analysis geometry, and then calculates the distance between the movement routes by an analysis geometry method. The collision can be estimated by considering the width, length, and direction of the cross section. In addition, when the collision prediction means 160 anticipates a collision between the simulation vehicle and the external vehicle, the distance and the length and the direction of the vehicle are calculated by calculating the distance between the moving route and the point in the plane analysis geometry by the analysis geometry method. Consideration can be given to the collision.

As a result of the determination in step S620, when the calculated distance between the moving routes of the vehicle gradually decreases and a collision between the vehicles is expected, the route constructing unit 140 performs the control under the control of the collision predicting means 160. The movement route of the vehicle may be changed (S630), or the driving state of the vehicle may be changed to a state such as pause, acceleration, or deceleration (S640).

For example, under the control of the collision estimating means 160, the route construction means 140 pauses a vehicle traveling far away in distance from the expected collision position after a certain distance, and closes in distance from the expected collision position. The collision between the vehicles can be prevented by continuously driving the vehicle or by temporarily accelerating the vehicle. Alternatively, according to the control of the collision predicting means 160, the collision predicting means 160 may reconstruct the determined movement route or the expected movement route of the vehicles expected to collide in consideration of the traffic allowance and the appropriate traffic traffic.

The collision avoidance method is selected by the route construction means 140 under the control of the collision prediction means 160 in the least effective manner in consideration of each situation in which collision between vehicles is expected, or randomly. Can be determined.

It is determined whether the collision between the vehicles is prevented by the step (S630, S640) (S650), repeating the step (S630, S640) until the collision is prevented, it is determined that the collision is prevented in the step (S650), or If a collision is not anticipated in step S620, the process moves to steps S610 and S620, calculates a distance between the movement routes of the vehicle, and then determines whether a collision is expected again.

7 is a flowchart illustrating a procedure of a traffic congestion cancellation method in a traffic simulation system according to an embodiment of the present invention.

The all-red time setting means 170 of the traffic volume simulation system 100 may determine whether vehicles traveling each road section are congested in step S710.

If it is determined in step S710 that no traffic congestion has occurred, wait until it occurs, and if it is determined that traffic congestion has occurred, it is determined whether the location where the traffic congestion has occurred is an intersection section in step S720. do.

When the traffic congestion occurs in the intersection section as a result of the determination in step S720, the all red time setting means 170 prohibits the entry of the vehicle into the intersection section for a predetermined time and simultaneously keeps the vehicle that has already entered. (S730).

Referring to FIG. 3, when a traffic jam occurs in an intersection section 300 in which a vehicle can travel in an E↔W direction and a S↔N direction, a predetermined time is set by the all red time setting means 170. In response to the control of the all red time setting means 170, the route configuring means 140 may move the vehicle 301 and 302 in the E → W direction to enter the intersection section 300 during the set all red time. , The vehicle 311, 312 in the W → E direction, the vehicles 317, 318 in the S → N direction, and the vehicles 315, 316 in the N → S direction are paused and at the same time within the intersection section 300. Vehicles 305, 306, 307, and 308 that have already entered, along with vehicles 303, 304, 309, 310, 313, 314, 319, and 320 that have left the intersection section 300, are moving in each road section. By continuing the driving according to, traffic congestion in the intersection section 300 can be eliminated.

It is determined whether the predetermined time set by the all-red time setting means 170 has elapsed (S750), and if the predetermined time has not yet elapsed, the process moves to step S720 and congestion at the intersection section. If all of the predetermined time has elapsed, it is determined whether the traffic congestion has been resolved.

If it is determined in step S720 that the traffic is not congested at the intersection section, the route configuration means 140 changes the movement route of the vehicles causing the traffic congestion or pauses the driving state of the vehicles, Change to a state such as acceleration or deceleration (S710), go to step S710 to determine whether the traffic congestion has been resolved.
