While the sustainable transportation system is considered as a global agenda (SDG 11), improvement of the public transportation system has a mandate. A successful public transport system relies on efficient first/last mile connectivity which in turn impacts transit ridership. In the context of access to transit, walking is considered as the most environment-friendly feeder option. Globally, the researchers and policy makers have adopted a thumb rule of 400 m. walking distance to access transit stops (especially bus) and 800 m. for train stations. But, in developing country like India, the thumb rule is yet to be confirmed. To determine the walking distance to transit stops in Indian scenario is challenging as it exhibits competitiveness with paratransit modes, as well as, a wide spread of aspects like constraint physical setting, socio-economic characteristics and travel nature of the commuters. This study aims to investigate the aspects walking distance traversed by the commuters toward transit stops and the factors responsible for this. It provides an insight to the distances covered vis-a-vis distance (400 m) as considered commonly. The study incorporates two-phase method—(a) A user-survey to explore the relation among the walking distance with socio-economic (age, income, occupation, vehicle ownership) and travel parameters (trip purpose and trip frequency) considering the physical setting of the zone as constant and (b) Determination of levels of bus stops within the study area based on a derived method of connectivity and explore the variability of catchment distances of walking. North Dum Dum Municipality, an Urban Local Body (ULB), adjacent to Kolkata City, has been considered as the study area, where feeder walking distances have been surveyed on two major transit roads. The study reveals that an average 700 m walking distance toward the nearest bus stop is common in the study area while the relational aspects are stronger when the distance is more than 400 m. The study also reveals that travel characteristics, and not the socio-economic characters, play a major role in determining access distance. The levels of bus stops in terms of connectivity also show significant variability of walking distance to access the bus stops.
