Under the Low Emissions Zone (LEZ) concept, special measures are implemented for a designated area within a metropolitan region to help deter the access of high-polluting vehicles and reduce the energy and emissions footprint of travel associated with the area.The Low Emissions Zone operational scenario defined by the Applications for the Environment: Real-Time Information Synthesis (AERIS) Program supports the operation of a LEZ that is responsive to real-time traffic and environmental conditions, facilitated by connected vehicle technology and in-vehicle alerts. Within the LEZ modeling effort undertaken in this project, the effects of incentive based policies where travelers receive a benefit for using low emission vehicles in the context of travel to the designated LEZ are simulated.
