The goal of this proposed project is to increase the safety of vulnerable road users (pedestrians & cyclists) by examining factors that help or hinder the process of making changes to the built environment (BE) for this purpose. By examining data collected from municipal, transportation, police services, public health, NGOs, and schoolboard sectors in the Cities of Calgary and Toronto the deliverables of this project aim to inform policy and decision-makers so that more resources and tools are allocated to BE changes that increase vulnerable road user safety.
