specific Embodiment approach 1
[0026] Specific implementation mode one: a kind of ground traffic organization optimization method applicable to the separated three-level interchange of the present embodiment The specific process is as follows:
[0027] Step 1: Assume that the north-south direction is taken as the direction of the underpass tunnel, and the east-west direction is taken as the direction of the overpass; the signal controls the operation rules of each entrance lane and the vehicles on the bypass waiting lane; the specific process is:
[0028] For the east-west entrance road, pre-signal lights are set before the U-turn lane under the overpass. The pre-signal lights include east-west straight ahead pre-signal lights, east-west left turn pre-signal lights, and east-west exit roads are equipped with north-south straight second stage signal lights before the U-turn lane;
[0029] When the north-south straight traffic signal light (the first phase of north-south straight traffic signal light) is on, t...
specific Embodiment approach 2
[0044] Specific implementation mode two: the difference between this implementation mode and specific implementation mode one is that in the third step of the complaint, the length G of the north-south straight line to be transferred area is determined according to step one, step two and the actual situation of the road, and the specific process is as follows:
[0045] The height of the U-turn lane under the overpass bridge is greater than or equal to 4.5m, and the length G of the north-south straight line waiting area should satisfy ① and ②, as shown in Figure (1).
[0046] The length G of the north-south straight waiting area should be determined in conjunction with the actual road conditions of the specific intersection, but it should be satisfied that during peak hours, if the north-south straight vehicles are in an unsaturated state, the straight waiting vehicles arriving within one signal cycle can all be within Stop and wait in the waiting area; if the north-south straig...
specific Embodiment approach 3
[0051] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the safe stopping distance Lc of the queuing vehicles is 8m.
[0052] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.
