A modeling framework for impact assessment of urban transport systems

An integrated software tool environment is presented, and a methodology is proposed for the operational support of the local authority, for analysis o f the impact of transport measures in terms of network energy consumption a nd pollutant emissions. It is based on work done by the European Union with in the save program (specific, actions for vigorous energy efficiency-Slam project (supporting local authorities methodology). As background, the Slam project is described, with the principal aspects and needs of environmenta l and traffic network management. The central section defines a methodology able to support technicians in recognizing the traffic asset and decision makers in evaluating interventions on urban transport infrastructures or te chnological systems. The role of the different models and their interaction s with the transport telematics services currently active on the Florence ( ItaIy) network is discussed. Finally, the procedure for calculating the tra ffic impacts on energy consumption is described with the help of a test cas e, the evaluation of a dedicated bus corridor in Florence.
