Dr Adrian Davis has been key to providing evidence to influence the work of many projects in Bristol including Cycling City and the Local Sustainable Transport Fund.
Please note that as of August 2019 Dr Adrian Davis is no longer producing Essential Evidence summaries for Bristol City Council, so no new ones will be uploaded to Travelwest. Dr Adrian continues to produce these for the Transport Research Institute at Edinburgh Napier University, where you can access his latest Essential Evidence.

Top line: Politics is a key determinant of transport policy. Attempts at evidence-based transport policy are often thwarted by ideological stances at odds with environmental sustainability, and focused on road building rather than on access for all.
Top line: The evidence for positive impacts in increasing physical activity is greatest for town and city-wide interventions. All studies addressing whole town or city-wide interventions showed increased levels of cycling and walking compared to controls.
Top line: The findings indicated that the sign-only 20mph intervention was successful in lowering vehicle speeds. Policy makers are encouraged to implement a careful monitoring of the effects of 20mph speed limit interventions on vehicle speeds in order to enable a meaningful evaluation of potential public health benefits.
Top line: Increasing levels of traffic policing reduces the number of road accidents and traffic violations.
Top line: In an urban area, 41% of short car trips (up to 69% when including escort, large-retail shopping and ‘as passenger’ car trips) could realistically be shifted to active travel.
Top line: City-wide sustainable travel interventions in three English towns led to increases in cycling and walking, sustained five year post project, while car use declined.
