Description of work
We are currently building a quantitative model of impacts of active travel policy scenarios for the six TAPAS case study cities. To populate variables and define relationships within the model, we use existing data from the literature and local available data sources. A simple quantitative framework using all cause mortality as indicator for health impacts as a result of physical activity, air pollution and traffic deaths has been already applied to case studies in France and Barcelona.
In addition to the central aim of the TAPAS project to develop the health impact assessment model, each TAPAS partner develops special research interests that they contribute to the program. The additional research aims at filling some of the important knowledge gaps and needs within the overall TAPAS framework.
A preliminary and evolving conceptual model (Figure 1) was developed and debated during a workshop held in Barcelona November 9th-11th 2009. Forty five international experts from 29 institutes/research groups and 12 different countries attended the meeting, reviewing the state of the art knowledge and discussing strengths and limitations of evidence of different linkages between urban and transportation policies, exposures and public health, to determine the relevance and appropriateness of exposures, outcomes, and exposure-response functions to be included in a quantitative assessment of health impacts of active travel policies.
