Cost–Benefit Analysis and Evolutionary Computing

This book systematically addresses the issue of interdependence between road projects in a network, when prioritising and scheduling road expansion and maintenance. The book presents substantial applications for both rural and urban projects and to the optimization of maintenance. The authors confirm the extreme sensitivity to project timing but also show that solutions with almost equal net present values may have dissimilar work schedules. One of these may be selected on environmental or other grounds without losing road user benefits. They go on to explore and demonstrate the issues associated with the integration of evolutionary computing techniques, transport modelling and cost–benefit analysis to achieve an optimal road investment timetable.
