Merging Model of Vehicle on Freeway Acceleration Lane

In order to work out merging regulation of ramp vehicles,video tape recorder and other observation device were used to investigate the merging characteristics data in many provinces and cities of China.Based on a lot of analysis and disposal for investigated characteristics data of freeway merging areas,the merging model and the travel distance model of ramp vehicles on acceleration lane without merging into is set up with differential method.This model explains the investigated results and it is significant to guide the engineering practice in the planning,design,management and control of freeway.
