| Abstract: | With the close road network including seven signalized intersections linked by four main roads in Nanning,the capital of Guangxi as an optimized object,the Paper preliminarily proposes a minimum signal timing scheme of vehicle delay by means of R.Kimber saturation flow calculation method and F.Webster crossroad signal timing theory.It also adopts genetic algorithms to optimize the signal timing scheme.Finally it conducts a traffic simulation with VISSIM and verifies the variation of service level index,thus to test the optimization scheme. |
