Intervention:
Six poor quality studies looked at improving cycle and walking links. All sought to increase connectivity of areas (such as neighbourhoods linking to commercial areas) by improving infrastructure. Intervention components included construction of traffic-free pathways and bridges and improving on- and off-street cycle lanes.
Evidence quality:
Results were inconsistent with three studies reporting significant positive effects for active travel outcomes. However, all studies were appraised as poor quality.
Generalisability:
Five of the six studies were conducted in the USA, with one study conducted in the UK. Therefore, the interventions could be partially generalisable to Wales, but the contextual environment of the different countries should be considered.
If proceeding with this intervention:
It is suggested that further robust research and thorough evaluation of impact is needed.
