摘要

In order to relieve traffic congestion and accidents caused by vehicles merging into main road from ramp, the important influence factors of merging behavior were analyzed firstly. Then, traffic conditions under different traffic volume of ramp and main road and different length of acceleration lane were simulated by Vissim. According to security and efficiency evaluation measured by conflict intensity and average delay, reasonable acceleration lane length was selected under certain traffic condition. Finally, the simulation model was compared with several other common models. Researches indicated that the model conformed to the actual situation.
