Differentiated Highway Toll Pricing Model Considering Carbon Emission Reduction Benefits

doi:10.12141/j.issn.1000-565X.230225

Abstract

Abstract:

Differentiated highway toll strategy can promote carbon emission reduction in the road field and boost the realization of the “double-carbon” goal. In this study, the carbon reduction benefits are considered as a part of the highway’s benefits. With the goal of simultaneously considering highway benefits and logistics enterprise costs, the study constructed a differentiated toll pricing model based on dual-layer programming. Firstly, the factors influencing truck route choices were analyzed; then Logit model was used to construct transfer traffic flow measurement method based on differentiated highway charging and carbon emission measurement method based on transferred traffic flow, and it proposed carbon trading pricing model under shadow price; finally, considering the partial maximization of carbon emission reduction benefits and the cost minimization of logistics enterprises, it proposed the dual-layer programming model of differentiated charging, and at the same time, the traffic flow data of highway A and parallel national and provincial roads in Shandong province were used for example analysis. The results indicate that, through the adjustment of differentiated highway toll strategy, the dual-layer programming model ensures optimal benefits for highway management while minimizing logistics enterprise costs. Furthermore, adjusting toll standards around the optimal toll rate has minimal impact on the benefits of Highway A, with benefit fluctuations remaining below 1.5%, demonstrating good revenue stability. The dual-layer programming model for differentiated toll pricing model proposed in this study can maximize the increase in highway carbon reduction benefits and minimize logistics enterprise costs.

Key words: differentiated toll, dual-layer programming model, carbon emission reduction benefit, optimization, empirical analysis
