基于出租车OD数据的居民活动强度时空特征研究
Spatial and temporal patterns of residents activity intensity based on taxi OD data
摘要
Abstract
This article intends to explore the spatial and temporal patterns of resident activities using GPS data of 500 taxis in Fuzhou city.Based on the analyst of spatial and temporal distribution of pick up and drop off positions of passengers,namely origin-destination (OD) points,we first divide the whole city area into 623 research units based on street crosses,and explore the spatial and temporal patterns of activity intensity for each unit by 6 periods.Further,we investigate spatial and temporal patterns of the passenger NFR(net flow ratio) that provides an new insight to residents activities pattern.The study shows that the pattern of resident activities is more obvious during the night especially after 21:00 PM than that in daytime,and the overall activity intensity reaches the maximum value of the day during this period.Besides,the distinction of activities between inside and outside the core area is more obvious at night,and there are characteristics of agglomeration for activities of the residents in the core area.The taxi activity intensities for overall area has a stable change during daylight,with an less obvious discipline of spatial distribution.During the morning rush hour,most units have an minim taxi activity intensities value and residents in these areas have greater tendency to flow out.关键词
