Intersection phase time distribution method based on pass demand balance
A technology of passing time and phase time, applied in the direction of traffic signal control, etc., can solve the problems of not meeting the overall optimization requirements of intersection signal distribution, ignoring non-critical traffic flow and cross-phase traffic flow requirements, etc., to improve the overall traffic efficiency, The effect of rational distribution scheme of signal phase time and optimized transit time at intersections

Embodiment
[0025] An intersection adopts a three-phase signal control method for six traffic flows, in which traffic flow 1 gets the right of way in phase 1 and phase 2, traffic flow 2 gets the right of way in phase 1, traffic flow 3 and traffic flow 4 get the right of way in phase 2, and traffic flow 5 The right of way is obtained in phase 3 and phase 1, and the traffic flow 6 obtains the right of way in phase 3. The corresponding relationship between the signal phase and the traffic flow is as follows figure 2 shown. It is known that the signal period length C=120s, and the shortest transit time required for traffic flow 1, 2, 3, 4, 5, and 6 is t min1 =58s,t min2 = 12s, t min3 = 36s, t min4 = 30s, t min5 =72s,t min6 = 48s.
[0026] Such as figure 1 As shown, this embodiment includes the following implementation steps:
[0027] Step 1 (first round): List all traffic flow combinations whose total duration is known and transit time is to be allocated.
[0028] In the first round...
