TEE: An advanced software tool for the modeling of direct impacts of transportation systems

The new version of TEE model (Transport Energy Environment) has been developed in the frame of the FP5 ISHTAR and HEARTS Projects with several features for better analyzing transport related direct impacts, taking into account vehicles kinematics, cold start emissions distribution and parking processes. Specific efforts were dedicated to the modeling of the effects of vehicles kinematics on hot emissions, where the software calculates link emissions by adopting average speed based functions, instantaneous emissions, or the innovative ‘kinematics correction functions’ model, and the modeling of parking processes which are relevant for cold start and evaporative emissions.
