Study on the Impact of Subway on Bike-Sharing in Suburbs

As Chinese cities continue to expand, the number of people moving to the suburbs has trended upwards. However, many of them work in downtown, and most suburban residents prefer driving as their daily commute mode due to patchy transportation. This paper studies whether the travel mode of residents changed after the operation of the subway in the suburbs by using 2 years bike-sharing usage data in Wujiang District. It explores the question by comparing the heatmaps of 2 years' bike-sharing usage drawn by ArcGIS and analyzing the socio-demographics associated with Bike+ Rail (B + R) tendency through an ordinal regression. The result shows that there was a sharp shift in bike-sharing usage since the advent of subway, and B + R was chosen as the new commuting mode by more residents. The attributes that facilitating B + R mode use are increasing age, being male, and longer commute distances.
