The invention discloses a grid reachability calculation method and system considering a closed operation relation and transfer duration, and relates to the technical field of urban traffic, first, source, road system, water system and research range data participating in grid reachability calculation are collected, and data preprocessing work is carried out; secondly, dividing a road network participating in grid reachability calculation into a blocked road system and a non-blocked road system; then, blocking area treatment is carried out on the blocked road system, and outward circulation opening treatment is carried out on the blocked road system; and meanwhile, through conversion of time and operation speed, simulation of transfer time of an external circulation port needing transfer time consumption is realized. And finally, generating a grid cost layer, and calculating the reachability of the grid. According to the method, multiple technical problems such as operation characteristic simulation of a closed road system, conversion simulation of relatively long station transfer time and how to avoid calculation of multiple transfer time in the multi-station operation process of the high-speed rail are solved.

    本发明公开了一种考虑封闭运行关系和换乘时长的栅格可达性计算方法、系统,涉及城市交通技术领域,首先,收集参与栅格可达性计算的源、道路系统、水系和研究范围数据,并进行数据预处理工作。其次,将参与栅格可达性计算的道路网络分为:封闭道路系统和非封闭道路系统。再,对封闭道路系统进行阻断区处理,并对封闭道路系统进行对外流通口处理。同时,通过时间和运行速度的转换,实现对需要换乘时间消耗的对外流通口的换乘时长模拟。最后,生成栅格成本图层,计算栅格可达性。本发明实现了对封闭式道路系统运行特征模拟,较长的站点换乘时间的换算模拟,以及高铁在多站点运行过程中如何避免计算多次换乘时间等诸多技术难题。
