摘要
共享单车在“低碳交通”的背景之下应运而生,给人们的出行带来了极大的便捷,同时,在共享单车的使用和管理过程中也存在一些问题,例如共享单车的投放不均衡等。本研究以北京市核心区为研究区,利用空间大数据分析等方法,对共享单车出行的时间序列和空间特征进行了分析,结果表明:(1)从共享单车出行的时间特征来看,一是从工作日的共享单车日均出行量远远大于休息日的日均出行量,工作日的日均出行量为623257辆,休息日的日均出行量为245039辆;二是工作日和休息日的共享单车出行高峰时段均为上午8点—9点以及下午的17点—18点;三是共享单车的出行时长主要集中在10 min以内,30 min以上的占比较少;(2)从共享单车出行的空间特征来看,一是北京市核心区工作日共享单车的出行呈现出“大聚集,小分散”的特点,且早高峰与晚高峰共享单车出行的空间流动趋势恰好相反,休息日呈现出“早分散,晚集聚”的特点。
Bike-sharing emerges in the context of"low-carbon transportation"and brings great convenience to people's short-distance travel.However,while sharing-bike has a huge positive impact on cities,there are also some problems,such as unbalanced distribution of bike-sharing and congestions caused by shared bikes on the side road and sidewalk.This study conducted a time and spatial analysis of bike-sharing in Dongcheng and Xicheng District of Beijing.Results gained from the research were summarized in aspects of time feature and spatial feature respectively(1)The average daily travel volume of shared bikes on working days,623,257,was much greater than that on the weekend,245,039;Moreover,the volume of shared bikes on weekdays and on the weekend reached peak from 8 am to 9 am and from 17 pm to 18 pm.In addition,the majority of the duration of riding was less than 10 minutes while 30 minutes or above riding occupies a small portion.(2)The shared bikes on weekdays were highly clustered around certain hotspots and the spatial flow of shared bike traffic on weekdays during morning rush-hour was opposite of that during evening rush-hour.On another hand,activities of the shared bike on the weekend occur in a scattered pattern in the morning while they were highly clustered in the evening.
