With nearly one million registrations at present, three-wheelers are the second-most popular vehicles on Sri Lankan roads, in terms of vehicle number. Promoting three-wheeler based taxi sharing could be one way of increasing high-occupancy vehicles on roads to cater to the existing trip purposes of road users while disincentivising the introduction of still-more three-wheelers to the existing fleet. A short corridor of 1.4km length between the University of Moratuwa (UOM) and Katubadde junction in Sri Lanka was considered as the case location for this research as shown in Figure1. Available modes of travel for users in this corridor are bus, car and three-wheeler (TW). During morning and evening peak times, the share of road users from UOM is considerable. Students of UOM being a population of nearly 8,000 account for a larger share (90%) of all commuters. In the case of the corridor concerned, bus and TW are the most common modes of transport among students. The research objectives were to identify: (1) barriers in implementing ridesharing, (2) suitable approach to initiate taxi share and (3) realistic design parameters for ridesharing for decision makers.
