【Abstract】 A combined strategy, flexible working arrangement(FWA) and time-dependent parking charges(TPC), is proposed to alleviate traffic congestion. The departure patterns and optimal parking charges are investigated with the combined strategy. A bi-level programming model is established to optimize the parking charges dynamically constrained to the dynamic user equilibrium. A gradient descent algorithm based on a sensitivity analysis is developed to solve the bi-level problem. The multi-user departure patterns and the optimal dynamic parking charges under different flexible user scales are demonstrated by a simulation approach. The results show that there are obvious staggered departures between flexible and non-flexible users. There is significant interacting effects between the two strategies, which yields better effects on congestion alleviation than implementing a single one separately. This study is expected to provide a new solution method for the traffic management optimization.更多还原
