Summary on Grant Application Form
The programme of work comprises interlocking elements whose relative importance would evolve in response to the emerging findings. At the core are a gravity model of demand and a timetable-planning process. The principle tasks are thus to develop the model, to use its geographically specific output as input to a timetable, and to assess the effectiveness of that timetable in meeting forecast demand. The sequence would be iterated for various strategies and for different solutions to timeabling problems. This element will be complemented by a purpose-designed survey which would focus on the access-stage, on mode-choice and hence diversion factors, and on stated-preference tests of attitudes towards regular timetables.Most timetables are necessarily a compromise between the needs of separate flows of traffic. The intention is to build the ideal timetable by introducing successive tranches of flows or stations to the network in a priority determined by the modelled forecasts of potential demand with a perfect service. At each step the provisional timetable would be fed back to the model in order to calculate what proportion of the potential could be realised. The analysis will be so conducted as to separate what would be achieved through a better ordering of services (and particularly by regularisation) from what would flow from a programme of capital investments.
