Urban Road User Charging Online Knowledge Base

What Are The Research Gaps?

In conclusion, it is worth considering briefly the gaps in knowledge relating to the economic impacts of urban road user charging.

We have already stated in this chapter that there is a distinct lack of empirical data. As a result the community lacks the substantive evidence base of experience and case studies of existing schemes needed to enable decision makers to assess the economic impacts of road user charging, particularly in smaller cities. This will only change as more schemes become operational and more data is collected. Particular emphasis should be given to the differential effects by sector of the economy and size of firm.

Whilst it is recognised that there is a “compelling link between the transport system and economic prosperity, with new transport connections enabling new economic relationships to be forged” (Eddington, 2006), little is known about the relationship between productivity and transport policy. This is an area of interest in which more research is required.

It is generally thought that users who place a higher value on time, such as the freight industry, should benefit from urban road user charging. However this argument is based primarily on theory and limited practical evidence. There is little knowledge regarding the impact of congestion charging on just-in-time inventory systems and this is a topic that needs a considerable amount of further research.
