    No 185: The effectiveness of a 20mph speed limit intervention on vehicle speeds in Bristol

    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.

    No. 177: Knowledge Translation for evidence-informed road safety

    There are significant future road safety gains to be made by more effective use of Knowledge Translation & Exchange (KTE) through improved policy and practice.

    No. 175 Traffic Safety Culture

    Traffic safety culture change requires both transformative actions at societal cultural levels and at the organisational level. Individuals and organisations over time will expect the traffic safety system organisations to expand their efforts to improve safety because the goal of zero fatalities has become embedded into the group culture.

    No 171: Visual looming & child pedestrian safety

    Children may not be able to detect vehicles approaching at speeds in excess of 20 mph. This creates a risk of injudicious road crossing in urban settings when traffic speeds are higher than 20 mph. The risk is exacerbated because vehicles moving faster than this speed are more likely to result in pedestrian fatalities.

    No 170: Urban cycle use, Safety in Numbers, and speed limits

    In the absence of cycle paths segregated from motorised traffic in urban areas the priority measure is to reduce the speed limit to 30km/h (20mph). In addition to built environment changes, including lower speed limits, Safety in Numbers also reduces injury risk as cycle use increases along a road link or at junctions.

    No. 169: Mobile phone use while driving

    Using a hands-free mobile phone is no safer than using a hand-held mobile phone. Both increase crash risk fourfold, but under-reporting at crash scenes of mobile phone use hampers analysis and future prevention efforts.
