Transport related air pollution and health impact

The main objective of the EU research project TRANSPHORM is to assess health impacts of transport-related airborne particulate matter (PM). Integrated assessment tools will be developed for scales ranging from city to European. The budget is 9 million euro and involves 20 partners from 12 countries.

Transport-related PM emissions are determined on both global (EU) and urban scales, based on transport activity data and improved emission factors of ultra-fine particle number (PN0.1) and mass fractions of PM1, PM2.5 and PM10.
To map transport activities in EU cities, Transport & Mobility Leuven will develop an urban transport model that holds an increased level of spatial detail compared to state-of-the-art models. The urban transport model will forecast transport activities in European cities up to 2030.

To quantify exposure to airborne PM in urban environments resulting from traffic, road, shipping, rail and aviation, we will develop improved and integrated air quality dispersion and exposure models for urban and regional scales. Targeted measurements will be conducted in Rotterdam, Helsinki, Oslo, London, Athens and Prague for source apportionment, exposure assessment and model evaluation.

The TRANSPHORM project finally delivers an integrated methodology to assess policies, measures or strategies that reduce health impacts of transport-related PM emissions. The developed tool will be used to generate mitigation and adaptation strategies for European cities and to make policy recommendations for the European Commission.
