Abstract When the direction of traffic flow is asymmetric and the road capacity is insufficient, the two-way traffic capacity of the road can adapt to traffic demand dynamically through changing the direction of the lane, which can ease traffic congestion. This paper proposes the implement conditions of variable lanes for road section and verifies that the intersections connected with variable lanes can deal with the increased traffic successfully. Meanwhile, a bi-level programming model was established. The upper-level is the integrated optimization of lane allocating and the lower-level represents a network equilibrium mode, which predicts the drivers’ reaction to any given lane allocation. Then, a heuristic solution algorithm is proposed to solve the bi-level programming model. The numerical test results show that the algorithm increases the capacity of the road network significantly and the two-way traffic is more balanced.

1 Introduction With the accelerated process of urbanization in China, the large and medium-sized cities are facing more and more transport problems. In order to alleviate traffic congestion, some domestic and abroad cities attempted to use the reversible lane technology to improve the operational status of the transportation system. Q.

Reversible lane is a method to increase traffic flow without adding additional roads or lanes. That is, when the two-way traffic flow distribution is not balanced in a road network, a lane direction will be changed temporarily to relieve the congestion problem as shown in Fig. 1. Brian Laurence introduced reversible lane application in the United States and pointed out that the United States also lacks available operating reversible lane design standards and implementation basis (see [1, 2]). In most cases, a fixed time period reversible lane control was taken based on road sections of the history of the survey data. Zhang introduced to use the bi-level programming model chaos optimization approach to seek the optimization method of the reversible lane in the road network [3]. Sheu studied the reversible lane in alleviating temporary road congestion caused by traffic accidents and other aspects of the application. A certain time-varying variable lane embodiment and forecasting vehicle traffic behavior, stochastic systems modeling method was proposed and the results can provide decision support for traffi
