深圳市出租车服务能力时空分析

Spatial and Temporal Analysis of Taxi Service Ability in Shenzhen City

以深圳市浮动车数据、行政区划和土地利用数据为基础,针对出租车载客状态的变化行为,提出出租车覆盖量、寻客效率指标,分析出租车服务能力的时空分异规律,同时对出租车服务能力与土地利用类型进行了相关性分析,结论如下：城市出租车服务能力具有明显的时变特征和空间分布差异;各行政区的出租车服务能力随时间变化浮动较大,在中午和晚上下班高峰期,服务能力相对较弱;出租车服务能力有明显的空间分布差异,受到土地利用分布的影响较大;出租车服务能力与商服用地有较强的正相关性,与工矿仓储用地有较强的负相关性。

On the basis of floating car data,zoning and land use data in Shenzhen,aimed at the taxi service state change behaviour,this paper proposes two indexes—taxi coverage and finding passenger efficiency and makes spatial and temporal analysis of taxi service ability and correlation analysis of taxi service ability and land use type.A conclusion is drawn that city＇s taxi service ability has strong spatial and temporal difference,each zone＇s taxi service ability changes a lot over time and it is relatively weak at noon and in the evening rush hour;taxi service ability has a strong positive correlation with business service land and has a strong negative correlation with the industrial warehouse space.
