Participatory transportation equity mapping

Transportation equity maps are essential for allocating limited public resources to achieve social equity. Transportation equity mapping uses accessibility as a primary indicator to measure inequity in a region. Traditional place-based accessibility measures can not offer fine-grained information to describe socio-economic characteristics and travel patterns individually. People-base accessibility measurements are capable of revealing inequity more accurately. Participatory GIS can enable every citizen to make contributions to equity mapping and express particular concerns about transportation inequality. This paper introduces a new approach to adopt web-based participatory GIS techniques for transportation equity mapping. A preliminary research prototype is presented to demonstrate the feasibility and effectiveness of the participatory equity mapping approach.
