Input: Seventeen studies were included. Ten were conducted in a school setting, two in universities, and five in workplaces. One study directly measured health outcomes, and all included studies measured travel outcomes. Two cluster randomised controlled trials in the school setting showed either no change in travel mode or mixed results. A randomised controlled trial in the workplace setting, conducted in a pre-selected group who were already contemplating or preparing for active travel, found improved health-related quality of life on some sub scales, and increased walking. Two controlled before-after studies found that school travel interventions increased walking. Other studies were judged to be at high risk of bias. No included studies were conducted in low- or middle-income countries, and no studies measured the social distribution of effects or adverse effects, such as injury. There is insufficient evidence to determine whether organisational travel plans are effective for improving health or changing travel mode. Organisational travel plans should be considered as complex health promotion interventions, with considerable potential to influence community health outcomes depending on the environmental context in which they are introduced. Given the current lack of evidence, organisational travel plans should be implemented in the context of robustly-designed research studies, such as well-designed cluster randomised trials.
Output:

This review focuses on travel plans for organisations, such as workplaces or schools. The main reasons for using travel plans are to reduce congestion and to be environmentally friendly, but travel plans are also commonly claimed to improve health. We included 17 studies in this review. One study found that promoting walking in a workplace improved some aspects of health, including mental health, but no other studies directly measured health effects. All 17 studies looked at changes in travel. Although some found that travel plans increased walking, others did not. Overall, there is not enough evidence to know whether travel plans are effective at changing the way people travel, or whether they improve health. Currently, organisational travel plans should be put in place as part of well-designed research studies.
