Description
Technical field
The present invention relates to signal control of intersection technical fields, in particular to using intersection number as the letter of target
Number timing method.
Background technique
According to statistics, national 38 key city bus traffic share rate average out to 21% in 2014, wherein Beijing, Shanghai
Equal big cities are more than 30%.And bicycle (including electric bicycle) trip accounts about 30%, shares the hair of bicycle in recent years
Exhibition is that short distance trip provides convenience, and the share rate of bicycle is risen in Urban Traffic.In addition green is advocated plus city
The ratio of trip, the construction for reinforcing walking block, pedestrian's trip is also gradually increased.However urban road signal is controlled and is handed over
For prong, the delay of walking, non-motor vehicle trip and transit trip is larger, by taking bus as an example, although many roads
Road is provided with bus special lane, but the speed of service of bus is not improved how many, is largely because intersection
Caused by message Controlled drug-release.
More to the method for Intersection Signal Timing in the world, there are commonly beauty in China's signal timing dial method at present
HCM method, the TRRL method of Britain (also referred to as Webster method), the ARRB method of Australia, China of state《Urban road design criterion》
Method, stop line method, conflict point method of recommendation etc., all these signal control methods are all with vehicle pass-through rate maximum or vehicle
The minimum optimization aim of delay, calculates the signal period, lets pass the time in the green light for distributing each phase according to vehicle flowrate, for
Pedestrian also only considers to show that the time can satisfy pedestrian's street crossing requirement in green light.
For it is this only by vehicle be consider object signal timing dial in a manner of the drawbacks of, patent CN105551266B is (a kind of
Control the calculation method of the flow of the people threshold value of traffic signaling equipment) propose that one kind extracts whole image shared by pedestrian by video image
The method that occupied area determines pedestrian's clearance threshold value, this mode are also qualitative consideration pedestrian stream amount problem, when pedestrian is super
Pedestrian direction is considered when crossing certain threshold value；Patent CN101799987A (a kind of self-adapting type intelligent traffic light and its control method)
Signal suitable for pedestrian crossing controls, and is to be become according to vehicle holding areas and the density of pedestrian holding areas to signal lamp
It changes, is only applicable to stream of people's control of peak time.
It is therefore proposed that a kind of signal timing dial method centered on person by intersection, with from the traffic of " with Che Weiben "
Signal control theory switchs to the traffic signalization theory of " people-oriented ".
Summary of the invention
In view of the above drawbacks of the prior art, the present invention is provided using intersection number as the signal timing dial side of target

The weight of traveler current number P1, P2, P3 are set as K1, K2, K3 by step 1.6), can use K1=0.2, K2 here
=0.3, K3=0.5；Can further will using different Vehicle emission person Pt31, Pt32, Pt33 ..., Pt3n weight is set as
K31,K32,K33…K3n；
Step 1.7) calculates relative transit total number of persons P, P=K1 × P1+K2 × P2+K3 × P3 or P=K1 of the phase
×P1+K2×P2+K3×(K31×Pt31+K32×Pt32+K33×Pt33+…+K3n×Pt3n)；
Step 2) calculates the relative transit total number of persons that other phases pass through intersection, with step 1.1) -1.7)；
The relative transit total number of persons that step 3) according to step 1), 2) calculates distributes thing, North and South direction green light shows the time,
Original signal timing method is optimized, lights signal lamp by this scheme.
In certain embodiments, nationality is obtained by pedestrian detection module, non-motor vehicle detection module and motor vehicle detecting module
Intersection pedestrian's situation, non-motor-car situation and motor vehicle situation data obtained are instant data, or pass through traffic tune
Look into or intersection historical data obtain historical data.
As shown in figure 3, in certain embodiments, in step 1.3), automobile-carried number by vehicle-mounted detector acquisition,
Vehicle on-board number is obtained by the smart phone mode of video detector or vehicle-mounted people, and vehicle-mounted number is passed through into channel radio
News are transmitted to integrative design intersection device or Signal control Center.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
