Appendix D: Gaps in the evidence

PHIAC identified a number of gaps in the evidence relating to the interventions under examination, based on an assessment of the evidence. These gaps are set out below.

  1. There is a lack of evidence on the effectiveness and cost effectiveness of woonerven, home zones and quiet lanes on preventing unintentional injuries on the road for children and young people under 15.

  2. There is a lack of evidence as to whether there was any differential effect of environmental interventions on different populations in terms of age, gender, rural/urban/road type and level of disadvantage.

  3. There is a lack of UK evidence on the effectiveness and cost effectiveness of safe routes to school on preventing injuries on the road in children and young people under 15.

  4. There is a lack of UK evidence on the effectiveness and cost effectiveness of cycle routes on preventing injuries on the road in children and young people under 15.

  5. There is a lack of evidence on the attitudes of drivers/road users to environmental interventions that prevent unintentional injuries in children on the road.

  6. There is a lack of UK evidence as to the barriers and facilitators of implementing environmental interventions to prevent unintentional injuries in children on the road, for example, which factors enhance successful implementation of design-based interventions.
