The built environment and pedestrian injuries

Principal investigator: Andrés Villaveces, Research Asst. Prof. Dept Epidemiology UNC, IPRC

Aims

The purpose of this study is to evaluate the association of changes in the characteristics of the built environment and pedestrianInjuries in two cities in Colombia

1. Cross-sectional measurement of the association of pedestrian injuries in relation to neighborhood diversity, density and design using the

Irvine-Minnesota inventory

2. Longitudinal measurement of the association of changes in the built environment in two cities

3. Use of TGIS to evaluate spatial and temporal risk of events

Built environment:

- Definition- Previous studies (mostly related to physical activity)- Measurement (Density, diversity, design)- Existing tools: 7 , use of Irvine-Minnesota Inventory

- Focused on walking environments- Component for pedestrians and interaction with traffic- Component for perceptions of safety/crime other injuries)

- Preliminary studies:- Injury data- Evaluation of interventions- Institutional experience- Pilot project funded
