Abstract:

The high-occupancy lane is an important traffic management plan that encourages carpooling, and thus achieves the ultimate goal of alleviating traffic congestion and improving traffic efficiency. This paper establishes a traffic system based on high-occupancy lanes, adding the impact of multi-class commuters with respect to additional carpooling cost and the urban rail transit mode. The mathematical programming model corresponding to the user equilibrium state and the system optimum state of the system is given, and the existence of the two states is proved. A numerical example is designed, and a comparison of user equilibrium state and system optimal state is carried out in the example. The results show that the traffic management department can significantly reduce the commute cost of commuters with low additional carpooling costs by developing a reasonable management plan. In other words, the management plan can improve traffic efficiency in the short term, while encouraging commuters to choose a lifestyle that is easy to carpool in the medium and long term to reduce the additional carpooling cost. In addition, by analyzing the length of the high- occupancy lane, it is found that the longer the length of the highoccupancy lane, the more significant the effect of the management scheme.
