Abstract: A public transit system in a city that serves a variety of passenger travel needs is the backbone of that urban territory. This research explores the optimal modal transition and integration, i.e. the most cost effective arrangement of public transit systems on an urban corridor, significantly improves the level of customer service, reduces capital and operating costs and energy use in planning perspective. The transit systems considered in this study for a given public transit corridor are: Regular bus, Bus rapid transit (BRT) and busway, collectively called rapid bus, and light rail transit (LRT) systems. This research focuses on a mathematical model along with a case study in the southeast in City of Calgary with several potential approaches that a transit agency can pursue to develop and evaluate the transition and integration of public transit strategies for a transit corridor with all line haul modes being fed by a feeder bus system. The transit mode options are designed to be chosen for each individual passenger from eight different scenarios in a given time horizon, i.e. the length of time, predefined for city planning: 2006, 2019, 2029, 2039, and 2076. With a given ridership level, the natural growth of passenger demand over the time horizons and the attracted new ridership demand after the implementation of a new mode are determined based on least cost deterministic mode choice behaviour of passengers. Passenger mode switching is iteratively determined based on total passenger cost by the minimization of the number of transfers, waiting time, access distance, and in-vehicle travel time for the revised ridership. The characteristics (speed, capacity) and operating parameters (dwell times, the number of stations/stops, stop spacings, schedule, headways and fleet size), and operating costs (including capital and maintenance costs) of bus and rail transit modes are also estimated and compared. The public transit systems at the optimal transition and integration point minimize the sum of total passenger costs and operating costs with more effectiveness and efficiency and range from regular bus to multimodal urban transit systems as transitions occur along the corridor over time.
