带能力约束的多模式交通均衡与道路资源优化配置方法

城市道路交通系统具有多方式混合运行的复杂特征，而道路资源的稀缺则造成其运行过程中部分路段能力供给不足，导致排队拥挤，严重影响系统运行状态。本项目拟建立带能力约束的多模式均衡模型对该复杂系统的长期运行状态进行估计和模拟，并在此基础上以提高交通系统运行效率、降低能源消耗、控制尾气排放等为目标，以道路使用收费和公交专用道设置为手段优化道路资源配置，改善交通系统运行状态。研究内容包括：（1）设置公交专用道前后瓶颈路段通行能力研究；（2）建立带能力约束的多模式交通均衡模型；（3）基于能力约束多模式交通均衡的公交专用道设置优化；（4）基于能力约束多模式交通均衡的差异化道路使用收费优化策略；（5）城市道路交通系统的多目标属性与综合优化。研究成果有利于推进道路资源在多种交通出行方式之间的合理分配，构建高效、节能、环保的城市道路交通系统，为城市经济社会的高效稳定可持续发展保驾护航。

Urban road traffic system has the complex characteristics of multi-mode mixed operation. The scarce attribute of the road resources causes insufficient supply of capacity in some road sections of urban road traffic system during operation, leading to queuing congestion and seriously affecting the system operation status. This project intends to establish the multi-modal traffic equilibrium models with capacity constraints to estimate and simulate the long-term operating status of the complex road traffic system. Based on these equilibrium models, improve the road traffic system operation status with the goals of higher operation efficiency, lower energy consumption and lower exhaust emissions by optimizing road resources reassignment with bus exclusive lanes and road pricing strategies. The main research contents include: (1) The research on the bottleneck capacity of road sections before and after the establishment of bus exclusive lanes; (2) The establishment of the multi-modal traffic equilibrium models with capacity constraints; (3) The optimization of the bus exclusive lanes setting based on multi-modal traffic equilibrium with capacity constraints; (4) Optimization of road pricing based on multi-modal traffic equilibrium with capacity constraints; (5) Multi-objective attributes and integrated optimization of urban road traffic system. The research results are conducive to promoting the rational distribution of road resources among various traffic modes, building a high efficient, energy-saving and environment-friendly urban road transport system, and ensuring the high efficient, stable and sustainable development of the urban economy and society.
