[0140] In the weaving area shown in the figure, A-C flow rate=5200pcu / h, A-D flow rate=390pcu / h, B-C flow rate=780pcu / h, B-D flow rate=130pcu / h; free flow velocity=120km / h h; length of interweaving section L=300m.
[0141] Now adopt the method in the present invention for the weaving area, according to the goal of maximizing the theoretical traffic capacity of the weaving area, carry out the calculation of lane function division in the weaving area, and compare the traffic capacity and service level with the traditional weaving area control method.
[0142] Step 1: Determine traffic operation parameters in the weaving area:
[0143] It is known that L=300m, N=4, V=120km / h
[0144] Step 2: Calculate traffic flow rate:
[0145] The total interleaving flow rate Q in the interleaving segment w =Q BC +Q AD =780+390=1170pcu / h
[0146] The total non-interleaved flow rate Q in the interleaved segment nw =Q AC +Q BD =5200+130=5330pcu / h
[0147] Total traffic flow rate Q=Q w ...
