The research results show that the implementation of reversible lane significantly increases the inbound and outbound traffic volume as well as travel speed in peak hour of Zizhu Yuan Road, and the utilization of a single lane tends to be equilibrated as traffic volume increased. The traffic volume of main parallel roads around Zizhu Yuan Road keeps almost unchanged in peak hour, which might be explained that reversible lane causes traffic flow redistribution within a greater range of road network and reaches a new equilibrium state.
