Abstract
The invention relates to the field of traffic management, in particular to a vehicle flow splitting method and system in an alert-situation disposing system. According to the vehicle flow splitting system, signals of traffic green lights and display of a guide screen can be managed, traffic jams can be managed in a cooperation mode, traffic road surface conditions can be detected in real time, feedback can be carried out in real time, the management hysteresis can be avoided, the alert-situation disposing efficiency of the traffic management department can be improved, and the traffic jams caused by traffic incidents can be avoided or relieved. The vehicle flow splitting method and system have the advantages that before road surface polices are dispatched to reach related intersections and related road sections to carry out dispersion, the system rapidly judges whether traffic flow splitting is carried out or not according to the number of lanes occupied when alert situations occur, a flow splitting strategy is automatically formulated and issued, the traffic jams caused by the traffic incidents are accordingly avoided or relieved, the alert-situation disposing speed is increased, and the commanding and dispatching efficiency is improved.
Description
Technical field
The present invention relates to field of traffic control, relate in particular to vehicle shunting method and system thereof in a kind of alert disposal system.
Background technology
Along with the development of urban construction, urban transportation can not be expanded accordingly, in the time there is larger traffic hazard, is easy to cause traffic jam.Traffic hazard (or other traffic events) occurring at present, generally all first disposed by road surface police strength, only in the time there is traffic congestion, just carry out traffic diverging and signal controlling, there is hysteresis quality in this way.As while there is the landslide of rainy day heavy showers, road, traffic hazard, initiate emergency plan is generally understood by public security traffic control department, discharging police strength goes to corresponding location to get rid of the danger, but due to hysteresis quality, road information real-time reason not in place, the police strength such as often cause to arrive dangerous situation local time, be faced with severe smooth traffic pressure, need to carry out long traffic dispersion and signal controlling, simultaneously cannot carry out comprehensive information reception and registration to vehicle afterwards.For this reason, need to consider how can as early as possible traffic hazard (or other traffic events) be estimated the impact of traffic, and judge whether accordingly to carry out vehicle shunting and how to carry out vehicle shunting, thereby avoid or alleviate therefore the traffic congestion producing.
Summary of the invention
The present invention overcomes above-mentioned weak point, and object is to provide a kind of vehicle shunting method in alert disposal system, promotes vehicle supervision department and disposes the efficiency of alert, avoids or alleviates the traffic congestion causing because of traffic events.
Another object of the present invention is to provide the vehicle shunting system in a kind of alert disposal system, this system can regulate the traffic green light signals when induced screen show, matching management traffic congestion, detects in real time traffic situation and feeds back in real time, avoids the hysteresis of management.

Below in conjunction with Fig. 3, method of the present invention is done to further explaination.
Suppose that following is known conditions:
1, all roads are two-way, Four-Lane Road, i.e. Wei Liang track, each section; At present the vehicle flowrate in all horizontal tracks (East and West direction) be 100 cars/minute;
2, longitudinally the vehicle flowrate in track (north-south) be 105 cars/minute;
3, when vehicle flowrate reach 120 cars/minute time, can cause congestion in road, shunt threshold values and be 120 cars/minute;
4, Wei San road <H now, there is traffic hazard apart from 50 meters of of crossing H point in C> section, has taken left lane.
First calculate alert section <H, vehicle flowrate=105*2=210 of C> car/minute, due to traffic hazard occurring, take a track, 210 cars of this road-section average vehicle flowrate/minute, reach shunting threshold values 120 cars/minute, per minute at least needs to shunt 90 cars, at alert section <H, H place, C> starting point crossing takes the measure of shunting as follows:
1) stop-light is set, forbids that vehicle sails <H into, C> section left lane;
2) shorten craspedodrome signal split, control the vehicle number that sails alert section into;
3) induced screen is issued induction information " traffic hazard occurs, 50 meters, front, can detour from Weier Road He Wei tetra-tunnels ".
Alert section <H, a left side of C> meets section <H, G> and the right side meet section <H, the maximal value that I> can shunt be 2=40 car of (120-100) */minute, be alert section <H, C> starting point crossing H can shunt 40*2=80 car/minute, also need to be from its forerunner section <M, 10 cars of H> shunting/minute, for this reason, need to be at its forerunner section <M, the starting point crossing M of H> takes following shunting measure:
1) shorten craspedodrome signal split, control the vehicle that sails this section into;
2) induced screen is issued induction information " traffic hazard occurs H place, crossing, can import and detour from both sides ".
Due to forerunner's road <M, H> starting point crossing M maximum can shunt 80 cars/minute vehicle flowrate, therefore need to be to its forerunner section <R, M> shunts.
The left adjacent section <G in alert section, B> accept average vehicle flow=(105*2+40)/2=125 the car of shunting after vehicle flowrate/minute, exceed shunting threshold values 120 cars/minute, therefore need vehicle flowrate to be diverted to its left adjacent section <F, A>.
At left adjacent section <G, the G place, starting point crossing of B> takes following shunting measure:
1) extend left green light signals ratio, control it and sail the vehicle in this section into;
2) induced screen is issued induction information " traffic hazard occurs Wei San road, right side, can detour from left side Weiyi Road ".
Need to be at section <G, the left adjacent section <F of B>, the vehicle flowrate of A> shunting be 2=10 car of (125-120) */minute, and the maximum vehicle flowrate that this section can be shunted be 2=30 car of (120-105) */minute, therefore do not need section <F, A> shunts again.
The right adjacent section <I in alert section, D> accept average vehicle flow=(105*2+40)/2=125 car recklessly of shunting vehicle flowrate/minute, exceed shunting threshold values 120 cars/minute, therefore need its right adjacent section <J of vehicle flowrate runner, E>.
At right adjacent section <I, the I place, starting point crossing of D> takes following shunting measure:
1) extend left green light signals ratio, control it and sail the vehicle in this section into;
2) induced screen is issued induction information " traffic hazard occurs Wei San road, left side, can detour from Woof five road, right side ".
Need to be at section <I, the left adjacent section <J of D>, the vehicle flowrate of E> shunting be 2=10 car of (125-120) */minute, and the maximum vehicle flowrate that this section can be shunted be 2=30 car of (120-105) */minute, therefore do not need section <J, E> shunts again.
By the demonstration of continuous shunting, signal lamp control, induced screen, vehicle flowrate is constantly segmented, before sending section, the relevant crossing of police strength arrival, road surface to be dredged, determine whether rapidly and carry out traffic diverging, and automatically realize the formulation of distributing strategy and issue, avoid or alleviate the traffic congestion causing because of traffic events, alleviate road surface police strength personnel's pressure, improve the speed of dealing with emergencies and dangerous situations, improve command scheduling efficiency.
Described in above, be specific embodiments of the invention and the know-why used, if the change of doing according to conception of the present invention, when its function producing does not exceed spiritual that instructions and accompanying drawing contain yet, must belong to protection scope of the present invention.
