Paper presented at the 31st Annual Southern African Transport Conference 9-12 July 2012 "Getting Southern Africa to Work", CSIR International Convention Centre, Pretoria, South Africa.
Transportation Demand Management (TDM, also called Mobility Management) is a general term for strategies that result in more efficient use of transportation resources. Voluntary TDM measures, such as the introduction of flexi time, ride sharing etc, if implemented and followed, should spread peak traffic over a longer period and improve the levels of service and reduce the negative impact of private vehicle travel on the environment. This paper analyses the potential benefits of the introduction of Voluntary TDM measures on a specific commuter route (Cape Road) in Port Elizabeth. The potential benefits were analysed in terms of time savings, cost savings, energy efficiency effects and a reduction in CO2 emissions. Microscopic modelling of specific work journeys on this route was carried out, comparing peak travel with off peak travel.
