Example one
The embodiment provides a wisdom urban traffic management and control system, as shown in figure 1, including two liang of intercommunications' vehicle terminal, traffic management platform and navigation planning platform, the vehicle terminal includes emergent vehicle terminal and ordinary vehicle terminal, the vehicle terminal indicates the vehicle-mounted terminal of installing on the vehicle, and emergent vehicle terminal indicates the vehicle-mounted terminal of installing on emergent vehicle, and ordinary vehicle terminal indicates the vehicle-mounted terminal of installing on ordinary vehicle. The navigation planning platform can be a high-grade map, a Baidu map, an Tencent map and the like.
The emergency vehicle terminal is used for sending an emergency navigation request to the navigation planning platform;
the navigation planning platform is used for planning a path according to the emergency navigation request and feeding back the planned emergency navigation route to the emergency vehicle terminal;
the emergency vehicle terminal is used for generating an emergency passing request according to the emergency navigation route and sending the generated emergency passing request to the traffic management platform;
the traffic management platform is used for generating emergency information and sending the emergency information to a common vehicle terminal on an emergency navigation route after receiving an emergency traffic request, reminding the common vehicle to give way for the emergency vehicle, and also generating a traffic light control scheme and controlling the indication state of a traffic light according to the traffic light control scheme, so that the traffic distance of the emergency vehicle and the traffic flow on the emergency navigation route are reduced.
In this embodiment, the emergency navigation request includes a geographic location of the vehicle, a destination, an emergency sign, and the like. In the emergency vehicle of the embodiment, for example, an ambulance, a rescue vehicle, or the like, which is loaded with emergency personnel, the vehicle can obtain the emergency sign after registering as the emergency vehicle on the traffic management platform.
After receiving the emergency navigation request, the navigation planning platform plans a path according to the emergency navigation request, and specifically includes:
analyzing the emergency navigation request to obtain the geographic position, the destination and the emergency mark of the vehicle;
determining the vehicle as an emergency vehicle according to the emergency sign;
after the emergency vehicle is determined, inquiring the corresponding destination geographic position according to the destination;
inquiring a one-way road between two positions according to the geographic position of the vehicle and the geographic position of a destination, and temporarily setting the one-way road as a two-way road;
and planning paths according to the geographic position of the vehicle, the geographic position of the destination and all double-way roads between the two positions, and selecting the optimal path as an emergency navigation route of the emergency vehicle.
For example, when an ambulance with a license plate number of 'YuxXX' returns to a hospital, an emergency navigation request is sent to the navigation planning platform due to traffic congestion. And after receiving the emergency navigation request, the navigation planning platform analyzes the request so as to obtain the analyzed geographic position, destination and emergency sign of the vehicle. And determining the 'YuxXX' vehicle as an emergency vehicle by the navigation planning platform through the emergency mark, and then planning the path in the emergency state. For many urban traffic, most roads are two-way roads, and few roads are one-way roads, because of the existence of one-way roads, vehicles need to detour from one place to another, thereby increasing the running time of vehicles (for example, when a is a one-way road from a to B, vehicles only need to pass through one road from a to B, but B to a, because the vehicles can not return from the original route, the vehicles need to pass through four roads, so that the vehicles need to take more time from B to a). Therefore, when the path is planned, the single-lane between the geographic position of the vehicle and the geographic position of the destination is temporarily set as the double-lane, so that the planned emergency navigation route is guaranteed to be the shortest route between the emergency vehicle and the destination.
And after receiving the emergency navigation route fed back by the navigation planning platform, the emergency vehicle generates an emergency passing request and sends the emergency passing request to the traffic management platform. And the traffic management platform analyzes the application passing request after receiving the application passing request so as to obtain the geographic position, the destination, the emergency sign and the emergency navigation route of the vehicle. After the request is analyzed, the traffic management platform determines that the vehicle is an emergency vehicle according to the emergency sign, and then reduces the traffic flow on the emergency navigation route mainly from two aspects.
On the one hand, generating emergency information and sending the emergency information to a common vehicle terminal on an emergency navigation route specifically comprises:
determining a geographical search range according to the emergency navigation route;
determining a common vehicle running in the geographic search range through position matching;
and sending the vehicle geographic position, the emergency navigation route and the emergency reminding information to a common vehicle terminal.
In this embodiment, after the traffic management platform sends the emergency information to the ordinary vehicle that is driving on the emergency navigation route, the driver of the ordinary vehicle can see the position, the emergency navigation route and the emergency reminding information of the current emergency vehicle through the vehicle-mounted terminal. Therefore, the driver can actively drive the vehicle away from the emergency navigation route to give way for the emergency vehicle. The active way giving depends on the initiative of a driver and is an uncontrollable factor, so the traffic management platform also reduces the traffic flow on the emergency navigation route by another measure.
And on the other hand, generating a traffic light control scheme and controlling the indication state of the traffic light according to the traffic light control scheme. The traffic light control scheme of the embodiment mainly comprises a first scheme and a second scheme, wherein the traffic light on the emergency navigation route is controlled according to the two specific schemes, so that emergency vehicles can pass through the emergency navigation route quickly.
Scheme one, according to vehicle geographical position and emergent navigation route control single-lane's traffic light, make the traffic light reversal indication of single-lane, specifically include:
identifying and judging whether a single-way lane change mark exists on the emergency navigation route;
if yes, calculating the relative distance between the vehicle geographic position and the geographic position of the one-way road intersection corresponding to the one-way road diversion sign;
judging whether the relative distance is smaller than a set distance;
and if the current time is less than the preset time, controlling the indicating state of a traffic light at the intersection of the one-way road to indicate that the emergency vehicle temporarily runs reversely on the one-way road.
In this embodiment, when the navigation planning platform performs path planning, if a single-lane re-routing is performed, the emergency navigation route has a single-lane re-routing sign, and if the single-lane re-routing is not performed, the emergency navigation route does not have the single-lane re-routing sign. The single-lane change sign is a sign for temporarily changing the direction of a single lane in order to allow emergency vehicles to pass through the sign quickly.
After the traffic management platform identifies that the single-lane re-routing sign exists on the emergency navigation route, distance calculation is carried out, the relative distance between the emergency vehicle and the single-lane intersection is calculated, and after the relative distance is smaller than a set distance (such as 100 meters, 200 meters and the like), the indicating state of the traffic light at the single-lane intersection is that the vehicle can pass in the reverse direction, so that the emergency vehicle is prevented from detouring, and the emergency vehicle can pass quickly. After the emergency vehicle passes through, the traffic light at the one-way intersection is restored to a normal indicating state. For example, a to B are one-way lanes, under normal conditions, traffic lights indicate that a vehicle may travel from a to B through a one-way lane; the emergency vehicle needs to go from B to A at the moment, and in the emergency state, in order to avoid the emergency vehicle to detour and reduce the passing time of the emergency vehicle, the traffic light indicates that the vehicle can go backwards from B to A through a one-way road.
According to the second scheme, the traffic lights are controlled according to the geographic position of the vehicle, the emergency navigation route and the traffic jam level, and the ordinary vehicle is prevented from entering the emergency navigation route, and the method specifically comprises the following steps:
determining a current control road section according to the geographical position of the vehicle and the emergency navigation route;
obtaining a traffic jam grade according to the traffic flow of the current control road section;
if the traffic jam level is slightly jammed, controlling the indicating state of a traffic light of the nearest intersection on the emergency navigation route, and preventing a common vehicle at the intersection from driving into the emergency navigation route;
if the traffic jam level is general jam, controlling the indication states of traffic lights of two nearest intersections on the emergency navigation route, and preventing common vehicles at the two intersections from driving into the emergency navigation route;
if the traffic jam level is comparatively jammed, controlling the indication states of traffic lights of three nearest intersections on the emergency navigation route, and preventing common vehicles at the three intersections from driving into the emergency navigation route;
and if the traffic jam level is serious jam, controlling the indicating states of traffic lights of the four nearest intersections on the emergency navigation route, and preventing the common vehicles at the four intersections from driving into the emergency navigation route.
According to the scheme, the traffic light is used for preventing the ordinary vehicle from entering the emergency navigation route, so that the traffic flow on the emergency navigation route is reduced. And determining the number of controlled intersections according to the traffic jam condition, wherein the more the traffic jam is serious, the more the number of controlled intersections is, and the traffic jam is not caused, so that the control is not performed. For example, the emergency vehicle 'yuxxxx' has a first intersection in front of 300, a second intersection in front of 700 m, a third intersection in front of 1100 m and a fourth intersection in front of 1500 m, the current control road section is 1500 m in front of the emergency vehicle, and the congestion condition of the road section is determined according to the traffic flow of 1500 m; if the emergency vehicle is slightly congested, controlling a traffic light at a first intersection in front of the emergency vehicle to prevent the common vehicle at the first intersection from entering the emergency navigation lane from other lanes; if the traffic lights are congested, controlling the traffic lights of the first intersection and the second intersection to prevent the common vehicles at the two intersections from entering the emergency navigation lane from other lanes; if the traffic congestion is relatively high, controlling traffic lights of the first intersection, the second intersection and the third intersection to prevent common vehicles at the three intersections from entering the emergency navigation lane from other lanes; and if the congestion is serious, controlling the common vehicles at the first intersection, the second intersection, the third intersection and the fourth intersection to drive into the emergency navigation lane from other lanes. Therefore, the more congested the traffic, the wider the control range is, and the traffic congestion situation on the emergency navigation route is relieved.
In conclusion, according to the embodiment, emergency route planning and traffic light control can be performed according to the vehicle geographic position and the destination of the emergency vehicle, so that traffic jam is reduced, the running time of the emergency vehicle is shortened, and people in a critical state are timely rescued or treated; in the embodiment, the temporary emergency reverse driving lane changing is carried out on the one-way lane, so that the lane detouring of the emergency vehicle when the emergency vehicle meets the one-way lane is avoided, and the driving time of the emergency vehicle is saved; according to the embodiment, the traffic light control range is adapted according to the traffic jam condition, so that the control on the traffic jam is optimized, the common vehicle is prevented from entering the emergency navigation route, and the traffic flow on the emergency navigation route is reduced.
Example two
The embodiment provides a smart city traffic control method, which is suitable for the smart city traffic control system of the first embodiment, as shown in fig. 2, and includes the following steps:
s1, the emergency vehicle terminal sends the emergency navigation request to the navigation planning platform;
s2, the navigation planning platform plans a path according to the emergency navigation request and feeds back the planned emergency navigation route to the emergency vehicle terminal;
s3, the emergency vehicle terminal generates an emergency passing request according to the emergency navigation route and sends the generated emergency passing request to the traffic management platform;
and S4, after receiving the emergency passing request, the traffic management platform generates emergency information and sends the emergency information to a common vehicle terminal on the emergency navigation route, so that the common vehicle is reminded to give way for the emergency vehicle, and a traffic light control scheme is generated and the indication state of the traffic light is controlled according to the traffic light control scheme, so that the passing distance of the emergency vehicle and the traffic flow on the emergency navigation route are reduced.
In this embodiment, the emergency navigation request includes a geographic location of the vehicle, a destination, an emergency sign, and the like. In the emergency vehicle of the embodiment, for example, an ambulance, a rescue vehicle, or the like, which is loaded with emergency personnel, the vehicle can obtain the emergency sign after registering as the emergency vehicle on the traffic management platform.
After receiving the emergency navigation request, the navigation planning platform plans a path according to the emergency navigation request, and specifically includes:
analyzing the emergency navigation request to obtain the geographic position, the destination and the emergency mark of the vehicle;
determining the vehicle as an emergency vehicle according to the emergency sign;
after the emergency vehicle is determined, inquiring the corresponding destination geographic position according to the destination;
inquiring a one-way road between two positions according to the geographic position of the vehicle and the geographic position of a destination, and temporarily setting the one-way road as a two-way road;
and planning paths according to the geographic position of the vehicle, the geographic position of the destination and all double-way roads between the two positions, and selecting the optimal path as an emergency navigation route of the emergency vehicle.
For example, when an ambulance with a license plate number of 'YuxXX' returns to a hospital, an emergency navigation request is sent to the navigation planning platform due to traffic congestion. And after receiving the emergency navigation request, the navigation planning platform analyzes the request so as to obtain the analyzed geographic position, destination and emergency sign of the vehicle. And determining the 'YuxXX' vehicle as an emergency vehicle by the navigation planning platform through the emergency mark, and then planning the path in the emergency state. For many urban traffic, most roads are two-way roads, and few roads are one-way roads, because of the existence of one-way roads, vehicles need to detour from one place to another, thereby increasing the running time of vehicles (for example, when a is a one-way road from a to B, vehicles only need to pass through one road from a to B, but B to a, because the vehicles can not return from the original route, the vehicles need to pass through four roads, so that the vehicles need to take more time from B to a). Therefore, when the path is planned, the single-lane between the geographic position of the vehicle and the geographic position of the destination is temporarily set as the double-lane, so that the planned emergency navigation route is guaranteed to be the shortest route between the emergency vehicle and the destination.
And after receiving the emergency navigation route fed back by the navigation planning platform, the emergency vehicle generates an emergency passing request and sends the emergency passing request to the traffic management platform. And the traffic management platform analyzes the application passing request after receiving the application passing request so as to obtain the geographic position, the destination, the emergency sign and the emergency navigation route of the vehicle. After the request is analyzed, the traffic management platform determines that the vehicle is an emergency vehicle according to the emergency sign, and then reduces the traffic flow on the emergency navigation route mainly from two aspects.
On the one hand, generating emergency information and sending the emergency information to a common vehicle terminal on an emergency navigation route specifically comprises:
determining a geographical search range according to the emergency navigation route;
determining a common vehicle running in the geographic search range through position matching;
and sending the vehicle geographic position, the emergency navigation route and the emergency reminding information to a common vehicle terminal.
In this embodiment, after the traffic management platform sends the emergency information to the ordinary vehicle that is driving on the emergency navigation route, the driver of the ordinary vehicle can see the position, the emergency navigation route and the emergency reminding information of the current emergency vehicle through the vehicle-mounted terminal. Therefore, the driver can actively drive the vehicle away from the emergency navigation route to give way for the emergency vehicle. The active way giving depends on the initiative of a driver and is an uncontrollable factor, so the traffic management platform also reduces the traffic flow on the emergency navigation route by another measure.
And on the other hand, generating a traffic light control scheme and controlling the indication state of the traffic light according to the traffic light control scheme. The traffic light control scheme of the embodiment mainly comprises a first scheme and a second scheme, wherein the traffic light on the emergency navigation route is controlled according to the two specific schemes, so that emergency vehicles can pass through the emergency navigation route quickly.
Scheme one, according to vehicle geographical position and emergent navigation route control single-lane's traffic light, make the traffic light reversal indication of single-lane, specifically include:
identifying and judging whether a single-way lane change mark exists on the emergency navigation route;
if yes, calculating the relative distance between the vehicle geographic position and the geographic position of the one-way road intersection corresponding to the one-way road diversion sign;
judging whether the relative distance is smaller than a set distance;
and if the current time is less than the preset time, controlling the indicating state of a traffic light at the intersection of the one-way road to indicate that the emergency vehicle temporarily runs reversely on the one-way road.
In this embodiment, when the navigation planning platform performs path planning, if a single-lane re-routing is performed, the emergency navigation route has a single-lane re-routing sign, and if the single-lane re-routing is not performed, the emergency navigation route does not have the single-lane re-routing sign. The single-lane change sign is a sign for temporarily changing the direction of a single lane in order to allow emergency vehicles to pass through the sign quickly.
After the traffic management platform identifies that the single-lane re-routing sign exists on the emergency navigation route, distance calculation is carried out, the relative distance between the emergency vehicle and the single-lane intersection is calculated, and after the relative distance is smaller than a set distance (such as 100 meters, 200 meters and the like), the indicating state of the traffic light at the single-lane intersection is that the vehicle can pass in the reverse direction, so that the emergency vehicle is prevented from detouring, and the emergency vehicle can pass quickly. After the emergency vehicle passes through, the traffic light at the one-way intersection is restored to a normal indicating state. For example, a to B are one-way lanes, under normal conditions, traffic lights indicate that a vehicle may travel from a to B through a one-way lane; the emergency vehicle needs to go from B to A at the moment, and in the emergency state, in order to avoid the emergency vehicle to detour and reduce the passing time of the emergency vehicle, the traffic light indicates that the vehicle can go backwards from B to A through a one-way road.
According to the second scheme, the traffic lights are controlled according to the geographic position of the vehicle, the emergency navigation route and the traffic jam level, and the ordinary vehicle is prevented from entering the emergency navigation route, and the method specifically comprises the following steps:
determining a current control road section according to the geographical position of the vehicle and the emergency navigation route;
obtaining a traffic jam grade according to the traffic flow of the current control road section;
if the traffic jam level is slightly jammed, controlling the indicating state of a traffic light of the nearest intersection on the emergency navigation route, and preventing a common vehicle at the intersection from driving into the emergency navigation route;
if the traffic jam level is general jam, controlling the indication states of traffic lights of two nearest intersections on the emergency navigation route, and preventing common vehicles at the two intersections from driving into the emergency navigation route;
if the traffic jam level is comparatively jammed, controlling the indication states of traffic lights of three nearest intersections on the emergency navigation route, and preventing common vehicles at the three intersections from driving into the emergency navigation route;
and if the traffic jam level is serious jam, controlling the indicating states of traffic lights of the four nearest intersections on the emergency navigation route, and preventing the common vehicles at the four intersections from driving into the emergency navigation route.
According to the scheme, the traffic light is used for preventing the ordinary vehicle from entering the emergency navigation route, so that the traffic flow on the emergency navigation route is reduced. And determining the number of controlled intersections according to the traffic jam condition, wherein the more the traffic jam is serious, the more the number of controlled intersections is, and the traffic jam is not caused, so that the control is not performed. For example, the emergency vehicle 'yuxxxx' has a first intersection in front of 300, a second intersection in front of 700 m, a third intersection in front of 1100 m and a fourth intersection in front of 1500 m, the current control road section is 1500 m in front of the emergency vehicle, and the congestion condition of the road section is determined according to the traffic flow of 1500 m; if the emergency vehicle is slightly congested, controlling a traffic light at a first intersection in front of the emergency vehicle to prevent the common vehicle at the first intersection from entering the emergency navigation lane from other lanes; if the traffic lights are congested, controlling the traffic lights of the first intersection and the second intersection to prevent the common vehicles at the two intersections from entering the emergency navigation lane from other lanes; if the traffic congestion is relatively high, controlling traffic lights of the first intersection, the second intersection and the third intersection to prevent common vehicles at the three intersections from entering the emergency navigation lane from other lanes; and if the congestion is serious, controlling the common vehicles at the first intersection, the second intersection, the third intersection and the fourth intersection to drive into the emergency navigation lane from other lanes. Therefore, the more congested the traffic, the wider the control range is, and the traffic congestion situation on the emergency navigation route is relieved.
In conclusion, according to the embodiment, emergency route planning and traffic light control can be performed according to the vehicle geographic position and the destination of the emergency vehicle, so that traffic jam is reduced, the running time of the emergency vehicle is shortened, and people in a critical state are timely rescued or treated; in the embodiment, the temporary emergency reverse driving lane changing is carried out on the one-way lane, so that the lane detouring of the emergency vehicle when the emergency vehicle meets the one-way lane is avoided, and the driving time of the emergency vehicle is saved; according to the embodiment, the traffic light control range is adapted according to the traffic jam condition, so that the control on the traffic jam is optimized, the common vehicle is prevented from entering the emergency navigation route, and the traffic flow on the emergency navigation route is reduced.
