ABSTRACT
Mixed traffic conditions, i.e., the presence of different vehicle classes in a toll lane, causes congestion, leading to extra delay and emissions. The determination of the emission levels in the field is tedious process and thus there is need to look over it. Further, the dynamic toll pricing schemes are well established in developed countries to mitigate the congestion, but its application in developing countries is not observed so far. Hence, an attempt is made in the present study to establish the dynamic toll rates based on emission at toll plazas operating under mixed traffic conditions. The sensitivity analysis is carried out by changing the traffic composition and the approach volume in simulation. After that, the traffic composition and approach volume-based emission estimation equations are developed that can be used to predict the emissions easily in the field. The methodology finally moves towards the development of emission-based toll rates (EBTR).
