【Abstract】:In view of the design issue of the entrance and exit of the main line of the passenger-freight separation road, the paper starts from the characteristics of the opening length of the entrance and exit, analyzes the relationship between the behavior of vehicles changing lanes and the opening length,proposes a model for determining the shortest length of entrance and exit openings by considering the corresponding characteristics and variables. And the paper uses engineering mathematics software to verify the results, gives the recommended value of the shortest opening of the entrance and exit at a certain driving speed.

【Key words】:road traffic; separation of passenger and freight; traffic safety; opening length design
