After entering the era of the city car, the car will be all over the streets, the kind of hope that a few large road projects to address the idea of ??the citys traffic congestion, apparently outdated. Only a few lines from the eyes to the face, that is to look to improve the capacity of the entire road network in all the roads up, trying to make all of the citys road network have become fast road. The research fieldwork Tianjin typical vehicle stop line at the intersection of imported road loss to start time for the green signal from the inlet channel to the vehicle start time start time span, considering the time period, imports of road lanes, different models mixing ratio, conditions and other factors affecting pedestrian crossing, the maximum loss statistics vehicle start time, minimum, average, typical intersection vehicle description Tianjin distribution losses start time. Combined with the loss of time to consider starting the vehicle, re-adjust and optimize the signal timing plan, the corresponding traffic simulation in traffic simulation software Vissim to travel time, queue length, number of stops, such as for the evaluation of indicators to assess the loss factors to consider vehicle start the pros and co
