Summary on Grant Application Form |
|
This project aims to develop a new algorithms approach to road traffic assignment which, by directly estimating differences, will be able to more accurately estimate the impact of (relatively) small traffic schemes or changes in the demand pattern. Traditionally this problem is approached by comparing the outputs of two independent traffic assignments to with scheme and without scheme networks. Very often the effect of the scheme can be effectively masked by the noise .The algorithms will be based on route flows as opposed to link flows which in turn 0offers substantial secondary benefits in terms of enhanced analysis facilities and reduced computational time for a wide range of applications. Prototype version of route-based algorithms have been developed and tested as part of MSc and PhD research and have confirmed the feasibility of the approach and its potential benefits; for example, they can provide much improved rates of convergence.
