【摘要】：为了研究公共自行车系统中自行车供给和自行车位置分布的距离效应对出行者借车行为的影响程度,选取华盛顿哥伦比亚特区的Capital Bikeshare公共自行车系统的高频数据,建立了出行者离散选择模型来最大化目标区域内人口的随机效用。其中,自行车供给效应包括借车时自行车供给边际效应、还车时车位可得性效应,距离效应包括单个车站距离效应、车站间距离效应。采用内外嵌套迭代算法对参数进行了求解。结果表明:出行者到自行车点步行距离每减少10%,系统中出借行为会增加2.9%;车站间最近距离每减少10%,出借行为会增加1%;在不增加车位情况下,增加自行车供给不会对出借行为造成明显影响;而车位供给每增加10%,出借行为会增加2.3%。
[Abstract]:In order to study the influence of distance effect of bicycle supply and bicycle location distribution on the behavior of travelers in public bicycle system, the high frequency data of Capital Bikeshare public bicycle system in Washington, D.C., were selected. A traveler's discrete selection model is established to maximize the random utility of the population in the target area. The effect of bicycle supply includes the marginal effect of bicycle supply when the car is borrowed, the availability effect of parking space when returning the car, the distance effect including the distance effect of single station and the effect of distance between stations. The inner and outer nested iterative algorithm is used to solve the parameters. The results show that with the distance of walking to the bicycle point decreasing by 10, the lending behavior of the system will increase by 2.9%, the nearest distance between stations will decrease by 10, and the lending behavior will increase by 1%. Without increasing the parking space, the increase of bicycle supply will not have a significant impact on the lending behavior, while the increase of parking space supply will increase the lending behavior by 2.3% for every 10% increase in parking space supply.
