The invention discloses a physical traffic accessibility evaluation method, which comprises the following steps of: dividing a research area into an evaluation area S and a peripheral area W, and dividing into a plurality of cells; determining the number and the number of cells included in the evaluation area S and the peripheral area W; determining a weight coefficient of the cell; determining a physical transportation mode and threshold time T of the road duration; determining a travel distance r; selecting one small area in the evaluation area S as a circle center to generate a travel circle; counting the number of cells and the number of the cells contained in the trip circle; according to the path network information and the average speed corresponding to the physical transportation mode, calculating the number of cells which can be reached through the shortest path within the threshold time T and the number of the cells; and calculating to obtain the reachability index of the cell serving as the circle center. According to the physical traffic accessibility assessment method, researchers can be helped to comprehensively and consistently assess, compare or research the physical traffic accessibility or convenience degree of different areas.
本发明公开了一种体力交通可达性的评估方法,该评估方法包括:将研究区域分为评估区S和外围区W,并划分出多个小区;确定评估区S和外围区W包含的小区数和小区编号;确定小区的权重系数;确定体力交通方式及路途时长的阈值时间T;确定出行距离r;选取评估区S内的一个小区作为圆心生成出行圈;统计出行圈包含的小区数和小区编号;根据路径网络信息以及体力交通方式对应的平均速度,计算在阈值时间T内通过最短路径可到达的小区数和小区编号;计算得出作为圆心的小区的可达性指标。本发明的体力交通可达性的评估方法,能够帮助研究人员全面、一致地对不同区域的体力交通可达性或者说便捷程度进行评估、对比或研究。
