摘要:

群体互动行为在人类社会生活中不可或缺,群体互动时空可达性旨在研究群体的时空条件下共同开展活动的自由度,长期以来一直受到地理学、交通学、规划学、行为学等不同领域的广泛关注。为弥补已有可达性方法对于活动开放时间及个人活动需求考虑的不足,本文拓展了时间地理学核心概念,基于群体互动时空路径与群体互动时空棱柱,进行群体互动时空可达性表达,并以活动地点兴趣度、互动时长可行度、活动地点吸引度、出行时间衰减度为评价因子,构建群体互动时空可达性评价模型,并以北京市为实验区验证了模型的有效性。该模型可为聚会活动地点推荐、移动社交网络、个人智能交通出行等应用提供一种有效的方案。

Abstract:

Human activities and interactions in space and time are essential in people's daily life. The study of space-time accessibility based on group interactions, concerning the freedom of group member behaviors, has attracted considerable research interests in many research fields, including geography, transportation, planning, and behavioral science. However, most existing accessibility evaluation methods are lack of considerations of the opening hours of facilities, for example the open hour from 9:00 am-9:00 pm, and individual preferences such as personal taste of food. In this paper, by extending individual space-time path and individual space-time prism, which are the key concepts of Hägerstrand's time geography, we proposed the group interactive space-time path and the group interactive space-time prism to represent interactions among people in space and time. Then we build a space-time accessibility evaluation model for group interactions by taking into account both the opening hours of facilities and the individual preferences. In particular, this accessibility evaluation model involves four evaluation factors, including group preference, minimum interaction time, facility attractiveness and travel time decay. Finally, we testify this model with a case study of group accessibility regarding to food service facilities in Beijing, China. The evaluated values of accessibility to food service facilities are graded and the top ones can be used for recommendations. For example, when people want to host a party at a restaurant, they may request that the flavor offered by this restaurant should satisfy every group member, the restaurant is open during the preferable time, and its location is not far away from this group of people. The experiment result shows that this model may provide good references to many applications such as group activity location recommendations, mobile social networks and individual travel-activity guide.
