TRAFFIC CENTRE LOCATION-ALLOCATION DECISIONS

This paper describes a computationally feasible methodology for optimising an urban transit system. This methodology, known as BUBLS (BUs Barn Location System), is currently used in capital projects planning. It is applied to a case study of the use of BC Transit, a large Canadian urban transit system. BUBLS uses a mixed integer programming model, to minimise costs for the appropriate number, location, and size of transit centres (depots, bus barns, or bus garages). This approach considers the existing configuration of bus routes, and a set of existing and candidate transit centre locations. Relevant costs include: (1) travel costs; (2) capital costs; and (3) operation costs. The methodology was tested on the Vancouver Regional Transit System of BC Transit, covering about 1800 sq km, and having over 650 diesel buses, 250 trolleybuses, light rail rapid transit (SkyTrain), and a ferry system (SeaBus). The locations of five new transit centres, additional to the five existing centres, were calculated. The final model had over 12,000 continuous assignment variables.
