Abstract:Taking Wangjiang Road in Hefei as an example, based on the measured data, a micro traffic model is constructed through the micro simulation software VISSIM. An evaluation system is proposed by taking the maximum queue length and delay as the node evaluation index, the road section operation speed as the section evaluation index and the average operation speed of the road network as the road network evaluation index. The impact of setting the bus lane on the traffic operation is quantitatively evaluated from the levels of the node, the road section and the road network so as to provide the reference for urban decision-makers.
