It has been suggested that speed limiters will have the most impact on vehicle speeds and hence road safety in general. Whilst it is technically feasible to develop a functional speed control system, it may be more difficult to design a system that drivers actually wish to use. It is essential...

This paper reports on key findings from a collaborative study whose objective was to produce an up-to-date guidance manual on the factors affecting the demand for public transport for use by public transport operators and planning authorities, and for academics and other researchers. Whilst a...

This paper reports research on the valuations of public transport time relative to car travel time and on the valuations of the walk time, wait time and service headway associated with public transport use. The results are derived from a meta-analysis of a very large data set of British...

The Department of Transport's recently launched National Cycling Strategy has the aim of doubling the number of cycle trips by 2002 with a further doubling by 2012. The Royal Commission on Environmental Pollution recommended a quadrupling of cycle trips to 10% of all journeys by 2005. Given the...

The evolution of the concept of social exclusion is briefly reviewed, with particular reference to recent papers published in Transport Policy. Two main issues have emerged, namely the difficulties in defining the concept and, more importantly, difficulties in operationalising the concept....

Twenty-one sources of error and bias in the appraisal of transport projects are identified. These relate to objectives, definitions, data, models and evaluation conventions. Objectives may be unclear, incompletely specified or inconsistent with appraisal criteria. Definitions of study areas and...

Option values and non-use values are well-known concepts in environmental economics, but so far there been few attempts to apply the concepts to the transportation field. This paper therefore firstly reviews empirical studies on transport option and non-use values, and secondly examines the...
