摘要
为弥补传统可达性动态反映不同位置上可利用时间限制的可达时空表现能力的不足,提出了一种基于时间地理的位置相关时空可达性表达方法,该方法以时间地理框架为基础,集成个人的活动需求,实现了面向个人的可达性表达,提高了时空可达性分析的实用价值和应用水平。
Location-specific space-time accessibility based on time geography framework is proposed, which has the ability of reflecting the relative accessibility between specific location and the whole region, and incorporating the constraint of available activity time of point of interest. This approach has implemented the personalized representation of accessibility by integrating the activity requirements, such as total activity time, available activity time and interesting activity opportunities. The method is helpful for individuals to explore their space-time accessibility for further activity decisions.
