Public transportation is often viewed as a means to address congestion in urban areas. However, it also serves another equally important societal function: providing mobility to those who lack access to alternative modes of transportation. Traditionally, public transit networks contain fixed bus routes and predetermined bus stations. Such systems are often found unaffordable and even inaccessible in areas and/or time periods with low travel demand. This talk focuses on alternative “structured” flexible-route transit systems, in which each bus is allowed to travel across a predetermined area to serve passengers, while these bus service areas collectively form a hybrid “grand” structure that resembles hub-and-spoke and grid networks. We analyze the agency and user cost components of this proposed system in idealized square cities and seek the optimum network layout, service area of each bus, and bus headway, to minimize the total system cost. They compare the performance of the proposed transit system with that of comparable systems (e.g. fixed-route transit network and taxi service), and show how each system is advantageous under certain passenger demand levels. It is found out that under low-to-moderate demand levels, the proposed flexible-route system has the lowest system cost. At the end of the talk, some ongoing extensions of the proposed transit system will be briefly discussed.
