| Abstract: | This paper analyzes the operational characteristics of vehicles on exclusive left-turn lane of signalized intersection with two phases and presents three left-turn modes of vehicles and influencing factors.Using probability theory,the paper develops three probability equations of realizing left-turn and respective applicable conditions.The calculation approach is also brought forward.The paper discusses how to determine the distribution of arrival of left-turn vehicles and the parameter estimation methods.Weibull distribution is recommended as headway distribution of through vehicles and figure method is to be adopted to get the parameters. |
