DISSERTATION ABSTRACT Bus Routes in Urban Corridm, Peter Gregory Furth, Department of Civil Engineering, Northeastern University, 360 Huntington Avenue, Boston, MA 02115 (Dissertation in the Department of Civil Engineering, MassachusettsInstitute of Technology, Cambridge,MA 02139). Designing
Bus service in urban corridors is typically provided with conventional local routes. Four different routing strategies are explored and shown to be potentially more efficientthan conventional local service in corridors with moderate to high demand. These strategies are deadheading some buses in the light direction; local zonal service, which is a system of local routes of different lengths, each having its own boarding zone inbound and alightingzone outbound; local zonal service and express zonal service together; and offering direct service (local and/or express) to more than one downtown terminal. The network of streets in a corridor that have bus service is assumed to be either a simple trunk or a tree.
A model of a bus route is developed, based upon which algorithms for finding optimal and near-optimal routing configurationsand service frequencies for each routing strategy are developed. The objective is to minimize a sum of operator and passenger costs, the demand pattern is general, the service and operating constraints are realistic, and the data requirements are modest.A closedform solutionis found for the problemof scheduling a route in which some runs deadhead. The zonal service algorithmsare dynamic programs. Case stpdies of corridors in Boston and Minneapolis demonstrate the value of these routing strategies and planning methods. In a high demand corridor, a routing configurationwas found that reduces operating cost by 2% relative to conventional local service. In moderate and high demand corridors in which some of these strategiesare already implementedbut without the aid of optimalplanningmethods,configurationswere found that required from 9 to 14%fewer vehicles than the existing configuration.
SPECIAL FEATURE The Centre de Recherche sur les Transports (Center for Transportation Research) of the University of Montreal is a University-wide facility designed to promote research in transportation throughout the departments and Schools of the University. Established in 1972,it is currently headed by Jean-Marc Rousseau. The team of faculty associates and researchers include,amongothers, Michael Florian, Marc Gaudry, Marc Los and Robert Chapleau. The Centre does not have teaching responsibilities but occasionally organizes international and local symposia,ad hoc trainingsessions and seminarsfor profes’sionals. Recent publicationsfrom the Centre are listed below. The complete list, as well as the publicationsthemselves, are availableby writingto the Librarian,at PO Box 6128, Station “A”, University of Montreal, Quebec, Canada H3C 3J7.
