CARTEEH has five interrelated focus areas, as shown below. The first three cover the spectrum from the transportation system (with a focus on alternative and emerging technologies), to transportation emissions and energy estimation, and an understanding of emissions exposures and its associated health impacts. The next focus area deals with integration of data between these three areas. Finally, an overarching policy and decision-making focus area addresses policy implications and informs decision-making.
