Effect of Walkability on Users Choice of “Walking” the Last Mile to Transit Stations: A Case of Delhi Metro

Abstract

There is growing recognition of the importance of Last Mile Connectivity (LMC) to mass transit systems. In the context of Delhi, albeit a shift can be seen in the provisioning of LMC, and despite previous studies indicating that more than 50% of metro rail users walk to and/or from metro stations, yet the seriousness with which pedestrian environment is woven into transit planning is lacking. The paper is based on an empirical study conducted by the author, of approximately 800 samples of metro users surveyed across seven stations of Delhi Metro, representing different station typologies, ridership and locational contexts. The paper focuses on the “walk” choice of users across a variety of factors related to their socio-economic strata, trip characteristics and station context. A parallel study is conducted to audit the pedestrian environment within one kilometre distance around each station. The paper further attempts to investigate whether pedestrian environment affects user choice of opting for “walk” as the last mile choice. It also ranks the performance of the case stations in terms of various attributes of walkability. In conclusion, the paper contends that overall walkability environment offered to transit commuters is crucial in the share of walk trips for last mile commute and the distance commuters are willing to walk. It recommends that walking as LMC choice needs to be promoted through enhanced user experience in absence of which a significant amount of last mile travel will happen through unsustainable mechanised modes.
