Most of the existing dynamic traffic assignment methodologies, which have been predominately travel time based, are not appropriate for use in a traffic network analysis where the environmental concerns prevail. The primary reason for this is that the travel time variables and the environmental variables, which include but are not limited to fuel consumption, vehicle emissions and traffic noise, have different sensitivities to the distribution of the vehicle's modal events. Therefore, the travel time based and the environmental based dynamic traffic assignments should virtually result in different dynamic network flows and queues. This research presents a new approach that attempts to explicitly incorporate the multiple transportation objectives into the dynamic traffic assignment/simulation model.
