Research on number of lane at toll stations of freeway mainline

In order to improve the traffic capacity of highway and toll station service levels, based on a survey of traffic parameters, taking queuing theory and statistical methods as the foundation, the paper obtains a reasonable service time and capacity at entrances and exits of toll station. And combined with energy-saving environmental protection and economic indicators, the paper determines a reasonable number of toll station import and export channels, which ensures the patency of the entire highway, and provides a scientific basis for the construction and management of highway intersection.
