The West Midlands Passenger Transport Executive commissioned Martin and Voorhees Associates (MVA) and Volvo Transportation Systems to carry out a study of the bus system in Coventry using the computer-aided network planning techniques developed by Volvo Transportation Systems. The study was the first in Britain to use these techniques. The objectives of the study were not only to develop a more cost-effective bus network for Coventry, but also to enable WMPTE to obtain direct experience of planning techniques with a view to including them in the PTE's continuing programme of network reviews and area reshaping studies throughout the West Midlands. Phase 1 consisted of the evaluation of the existing Coventry bus network. The principal elements of phase 1 were: (I) the collection and analysis of data on existing travel by public transport in Coventry; (II) representing the existing public transport system (the "base network") on the computer; (III) loading ("assigning") the passenger trips on to the computer representation of the base network using the passenger assignment and network evaluation program - the route network analysis or rna; (IV) analysing the performance of the base network using the data provided by the rna on passenger loadings, the standard of travel, costs and revenue, together with various manual analyses. An important element of phase 1 was to demonstrate that the rna could reproduce accurately the loadings on the present network. Phase 2 consisted of the development and evaluation of various network options for Coventry and the preparation and otpimisation of a recommended plan. Two approaches to network design were used in the study. The first consisted of the manual generation of two alternative networks. The design of these networks was guided by the evaluation of the base network, together with the local knowledge of pte officers. The second approach involved the generation of a route network by the computer. A computer designed network has the advantage of being unconstrained by the existing route network or even the existing pattern of demand, and may thus include ideas that may be overlooked by the operator. The principal input data for the computer designed network (cdn) programs are: (I) zonal land use parameters (population, employment etc) which are used to generate a `desire' travel pattern; (II) details of the road network suitable for bus operations, and (III) lists of permitted terminal points for buses. The manually designed and computer designed networks were then evaluated using the rna. The final stage consisted of the development of the plan using computerised optimisation techniques. Alternative policy options were examined including the level of costs and revenues, and the size of the bus fleet. Discussions are currently taking place with a view to the implementation of the preferred network. (TRRL)
