Another reason for physical inactivity is the perception by populations that there is nowhere safe to do so. As cities become more populated, the increased need for housing overtakes the desire for parks, cycle and walk ways therefore increasing the amount of physical inactivity in the population. Ways that can help increase the amount of physical activity is to plan and build the environment in a way that makes the population of the community feel safe to be physically active in the area. This could be done for example by slowing speed limits to safer speeds and providing safe street crossings and also by building infrastructure close to the street and pathways with safe pedestrian and cycle access and safe bike parking. By implementing these simple changes into communities, the residents will have an increased feel in security and therefore increase their daily physical activity.
