从拥挤的落客车道获得更高的出租车流出量:基于模拟的政策研究

Achieving higher taxi outflows from a congested drop-off lane: a simulation-based policy study

摘要:

我们研究了出租车和其他共享乘车服务在机场和铁路终点站下车的特殊车道。禁止车辆在车道内超车。因此,在繁忙期间,他们必须以先进先出的方式排队等候。乘客通常只在到达客运大楼入口附近的落客区后才下车。然而,当等待时间变长时,一些车辆在期望区域之前将其顾客卸载。选取华东某训练站作为案例研究。现时,该处的先进先出落客线由警察管理,他们容许的士分批驶入落客线。由于航站楼附近的路边空间经常被闲置,因此观察到的效率低下。这是真实的,即使补充批次的出租车被释放到车道上,努力填补这些空间。先进先出落客通道的微观模拟模型是在内部开发的,并精心校准到研究现场测量的数据。仿真实验表明,取消先进先出车道的现行出租车分流策略可以使出租车流出量增加26%以上。进一步的实验表明,甚至更大的收益可以实现的出租车,但要求他们放电时,被迫下游队列停止一个规定的距离提前所需的落客区的顾客。预计进一步的收益,要求领导出租车在每一批只有在行驶规定的距离超出所需的位置后,释放其乘客。实际影响进行了讨论,在目前的繁荣共享乘车服务。

英文摘要:

We examine special lanes used by taxis and other shared-ride services to drop-off patrons at airport and rail terminals. Vehicles are prohibited from overtaking each other within the lane. They must therefore wait in a first-in-first-out queue during busy periods. Patrons are often discharged from vehicles only upon reaching a desired drop-off area near the terminal entrance. When wait times grow long, however, some vehicles discharge their patrons in advance of that desired area. A train station in Eastern China is selected as a case study. Its FIFO drop-off lane is presently managed by policemen who allow taxis to enter the lane in batched fashion. Inefficiencies are observed because curb space near the terminal often goes unused. This is true even when supplemental batches of taxis are released into the lane in efforts to fill those spaces. A microscopic simulation model of a FIFO drop-off lane is developed in-house, and is painstakingly calibrated to data measured at the study site. Simulation experiments indicate that rescinding the FIFO lane's present batching strategy can increase taxi outflow by more than 26 percent. Further experiments show that even greater gains can be achieved by batching taxis, but requiring them to discharge patrons when forced by downstream queues to stop a prescribed distance in advance of a desired drop-off area. Further gains were predicted by requiring the lead taxi in each batch to discharge its patron only after travelling a prescribed distance beyond a desired location. Practical implications are discussed in light of the present boom in shared-ride services.
