Project: Modelling Peak Spreading & Trip Retiming - Phase 2

Reference: H051B

Last update: 19/11/2003 15:11:03

Objectives

There is increasing evidence that peak spreading and retiming are important responses to congestion. In the SACTRA report on Trunk Roads and the Generation of Traffic, it was suggested that existing techniques for modelling these effects are limited and poorly developed.
A literature review of previous work and an assessment of possible future work and the key issues most in need of examination and development has led to a second phase designed to find sound practical techniques for peak spreading and trip retiming.

It is expected that software will be developed that is suitable for use with current traffic assignment packages, and case study applications will be implemented.

Description

This research intends to look at practical ways tomodel peak-spreading and trip retiming. There is increasing evidence that peak spreading and retiming are important responses to congestion. In the SACTRA report on Trunk Roads and the Generation of Traffic, it was suggested that existing techniques for modelling these effects are limited and poorly developed.

Summary of results

  1. The project succceeded in developing operational methods for time period choice, that combined early and late cheduling with network based traffic assigment.
