高速公路绿色通行优先的交通量分配模型及算法

Traffic Assignment Model and Algorithm Based on Priority of Green Traffic on Freeways

摘要: 交通是重要的碳排放源，优先发展低碳或零碳的绿色交通，是城市和国家实现碳达峰、碳中和目标的关键策略，对减缓全球气候变化至关重要。高速公路绿色交通优先通行的管理和模型研究非常重要。本文提出了一种绿色交通优先通行的交通量分配模型，并给出对应的求解方法。在高速公路上，绿色交通的择路行为服从古诺特集团法则，与其他交通相比可以优先通行，联合体的共同目标是绿色交通运输总时间和碳排放加权总量最小；非绿色车辆在选择路径时须给绿色车辆让行。文章最后通过一个算例证明了开发模型的有效性。

Abstract: Transportation is a significant source of carbon emissions. Prioritizing the development of low-carbon or zero-carbon green transportation is a critical strategy for cities and nations to achieve carbon peak and carbon neutrality goals, playing a vital role in mitigating global climate change. Research on the management and modeling of green transportation priority on highways is therefore highly important. This paper proposes a traffic assignment model for green transportation priority and presents a corresponding solution method. On the transportation network, the route choices of green vehicles follow the Cournot-Nash (CN) principle and enjoy priority passage rights, while collectively forming a community aimed at minimizing the total travel time and weighted total carbon emissions. Other social vehicles fully cooperate with the priority of green transportation. Finally, a simple case study verifies the effectiveness of the model and algorithm.
