Genoa – Baseline scenario (CO emissions)
The Genoa case history Fifth framework programme of the European Community Environment and sustainable development SUTRA [ Sustainable Urban TRAnsportation ] ARPAL “Validation” of the TREM results: spatially disaggregated traffic emission through a comparison with “CORINAIR” emission coefficient: spatially aggregated (top-down approach) traffic emission Use of averaged emission coefficients developed by ANPA (Italian national Environmental Protection Agency) for typical Italian urban driving cycles. Comparison at “elementary data”: Selected vehicle class (e.g., pre-ECE, <1.4 l) Selected emission (e.g., “hot”, “cold”) TREM: result analysis hours simulations 2. VISUM Assignment 3. TREM simulations

Fifth framework programme of the European Community Environment and sustainable development SUTRA [ Sustainable Urban TRAnsportation ] ARPAL The Genoa case history Transportation system response to CSs: 2) Ratio between Lisbon and Genoa The “linear” town reacts in a more rigid way to exogenous pushes than the distributed town, this reflects in time spent to cover a km of network 1) Variation in time spent to cover a kilometer -In conditions of traffic congestion -In traffic Jams - Total

Fifth framework programme of the European Community Environment and sustainable development SUTRA [ Sustainable Urban TRAnsportation ] ARPAL The Genoa case history Concentration of pollutants in CSs: Geometry of the AQ stations network is projected to measure hot spot data, therefore city level averages are generally underestimated -Next refining will be analysis of values in a smaller monitored area

Conclusions & Outlook Conclusion and Outlook: SUTRA has offered a unique opportunity to: develop, calibrate and validate an “integrated transport & impact assessment modelling suite”; compare the obtained results with previous experiences; investigate future and city specific scenarios. A particolar attention has been done to “put and keep the results in context”, being both Genoa partner (Municipal Transport Office and Regional Environmental Agency) local operative Authorities Among the main trade-offs of the SUTRA project: implementation of an operative transport model (that became the local standard); synergy bewteen transport and environmental Authorities, as well as other UE partners; disaggregation and detailed studies of local “hot-spot” for the main transport related pollutants ( recent EU “air quality” directives)
