[069] How Node-place Index Affects Pedestrian Movements
Keywords:Pedestrian movement index, Transit-Oriented Development, Node-place index, walkability, GPS Data
Transit-Oriented Development (TOD) aims to encourage people to walk and use public transit instead of automobiles. Walkability is a key factor when evaluating metro station areas under the TOD concept because pedestrian access between a transit node and its surrounding area is important. The node-place model has been widely employed to evaluate the metro station area. It is essential to investigate the relationship between the node-place index and pedestrian movements in metro station areas for successful TOD development. This study develops the pedestrian movement indexes (PMIs) based on GPS data and clarifies how the node-place indexes affect pedestrian movement within metro station areas. The major findings are as follows. Three PMIs (count, distance, and time) explain different aspects of pedestrian movement. Node-place indexes have significant effects on PMIs, and the effects vary according to PMIs. First, high density and well-connected streets increase the number of visitors and their stay time but decrease the distance due to proximity and connectivity between facilities. Second, the high frequency of railways and buses shows a negative relationship with time due to the short waiting time. Lastly, public and commercial land-use attract many visitors. Our findings indicate that the appropriate spatial design varies according to policy objectives.
