Transit service, System availability, Service coverage


Over the last few years, transportation policies have aimed to shift transport demand from private car to transit systems. To achieve this objective, supplied transit services must be available to as many users as possible. Access to transit stops is an important factor. This research focuses on defining the service coverage area of a transit service, which is the area within walking distance of a transit stop, using a methodology suggested by the Transportation Research Board. The aim of this research is to calculate service coverage area for a transit system operating in the urban area of an Italian city. The results showed that street connectivity factor, grade factor and population factor have great influence on the determination of service coverage area, whereas pedestrian crossing factor does not impact service coverage area. However, grade factor was calibrated for American cities and does not fit the case of European and Italian cities, which have different topographical characteristics.
