摘要
与机动车数量激增类似,泊位短缺也是导致城市交通拥堵主要问题之一,在不增加车位的情况下提高泊车位利用率也是解决交通拥堵的一种方法。针对城市“泊车难”和部分泊车场利用率较低的问题,考虑了用户的偏好特征,研究了一种具有用户偏好的泊车位共享策略。考虑存在三种不同的泊车方式,在中央商务区(CBD)等待泊车、共享私人泊位、共享公共泊位,运用累积前景理论分析用户的泊车成本,发现用户在不同情形下的选择存在差异。平台通过对关键路径法修改,采用了偏好分组法进行分配。算例对偏好分组的结果与采用关键路径法的分配结果进行了比较,结果表明,基于偏好分组法的分配满足了更多的用户需求,平台收益更高,为管理者提供决策参考。
The shortage of parking spaces is one of the main problems leading to urban traffic congestion as well as the surge in the number of motor vehicles.Improving the utilization of parking spaces without increasing the number of park-ing spaces is one of the effective ways to alleviate the traffic congestion.A shared parking strategy based on users’prefer-ence is proposed to solve the problem of“parking difficulty”and low utilization ratio of some parking slots.Three differ-ent parking modes are considered:waiting parkingmodein CBD,sharing private parking and sharing public parking,the cumulative prospect theory is used to analyze the cruise cost of users,it is found that the choice of users in different situa-tions is different.The preference grouping method are adopted for allocation by modifying the critical path method,the results of the preference grouping are compared with those of the critical path method,which shows that the distribution based on preference grouping method makes the platform more profitable,satisfies more users’demands,which provides reference for the management of parking spaces.
