High toll charges force trucks to avoid quality roads, leading to increased emissions. We propose a model in this study to find an effective toll charging scheme to minimize total network vehicular emissions while maintaining reasonable revenue for investors. A bi-level modeling approach is used, where toll prices for multi-class vehicles are decided in the upper level and user response to toll charges are predicted using user equilibrium conditions with multi-class traffic assignment in the lower level. The model takes into consideration both toll revenue and total vehicle operating costs to produce an acceptable solution for both investors and road users. All major components of hazardous ..
