This study aims to develop a macroscopic traffic simulator that can incorporate the characteristics of heavy vehicles for investigating the effects of urban transport measures. The performance of the simulator is identified using a real road network, and then the simulator is applied to a test road network for assessing the influence of access restrictions of heavy vehicles to city centre. Results showed that total travel times and NOx emissions reduce in the restricted area, but increase in the whole road network. The importance of selecting the areas where access restrictions are implemented is also identified.
