What are the benefits of investing in Travel Demand Management initiatives? Can these benefits be compared with the benefits of investing in new major roading projects? This paper sets out the steps taken to develop an answer to this question: defining low, medium and high levels of TDM; developing tools to model TDM investments alongside roading and PT; evaluating the results of this modelling for four scenarios: maximum spending on roads; committed TDM & PT projects only, mix of roading and PT improvements with low TDM, mix of roading and PT improvements with medium TDM, mix of roading and PT improvements with high TDM. Some conclusions are then presented which interpret the results of this modelling. (a) For the covering entry of this conference, please see ITRD abstract no. E213716.
