为了使停车费率策略更加有效地实现停车资源与道路资源的均衡利用,根据效用理论与非集计模型,建立停车选择行为模型,确定停车费率等变量与选择概率及停车流量的函数关系.在此基础上,建立以出行者总停车选择效用最大化为目标的浮动式停车计费模型,将停车场利用率均衡与道路饱和度均衡作为约束,采用序列二次规划方法进行求解,并通过算例验证了模型的可行性与有效性.研究结果表明:浮动式停车费率可实现路网流量分配均衡和停车场利用率均衡,相比于固定费率可提高138%的停车社会效益,且浮动式停车费率对停车系统的调控作用优于道路系统.%In order to make parking pricing strategy more effective in utilized equilibrium of parking resources and road resources, based on utility theory and disaggregate model, parking choice behavior model was set up,and the functional relationship between parking fee and parking flow was calculated. On this basis, the maximum parking choice utility was taken as decision target, the equilibrium of the parking occupancy rate and the road saturation were taken as constraints, and the optimization model of floating parking fee was set up. The optimization model was accomplished by sequential quadratic programming method, and the feasibility and validity of the model was verified by an example. The findings obtained from this study are as following: floating parking fee can actualize traffic assignment equilibrium and parking occupancy rate equilibrium,and the parking social benefits can be increased by 138%,compared to the fixed parking price strategy. The regulation effect of floating parking fee on parking system is better than that of the road system.
