出行需求管理(TDM)是一项重要措施，有助于实现高效和可持续的交通系统。然而，在交通拥堵最严重的城市，实施单一的TDM措施可能不足以缓解拥堵，因为这种情况下的拥堵机制非常复杂，涉及不同交通方式之间的相互作用。在文献中很少讨论多个TDM措施的实施。因此，在本研究中，我们提出了一个由公交专用道和车辆拥堵收费组成的基于仿真的联合优化框架。优化过程的目标是基于一种称为多模式宏观基本图(MMFD)的先进宏观流理论来最小化拥堵成本，该图能够反映多式联运系统的宏观交通动态。在该框架中，我们开发了基于MMFD的拥堵收费方案，并将出行者的行为模型(即联合出发时间和方式选择)与微观交通模拟器相结合。我们以东京中心区为例进行研究。模拟结果表明，东京公交专用道的最优空间分配为4.7%，而最优拥挤定价方案表明，在上午7：30至8：00之间收取900日元，在上午8：00至8：30之间收取300日元的费用。
Travel demand management (TDM) is an important measure that will aid in the realization of efficient and sustainable transportation systems. However, in cities where the most serious traffic congestion occurs, implementation of a single TDM measure might not be enough to reduce congestion, because the congestion mechanism in this case is highly complex and involves different transportation modes interacting with each other. Implementation of multiple TDM measures has rarely been discussed in the literature. Therefore, in this study, we propose a simulation-based joint optimization framework composed of dedicated bus lanes and vehicular congestion pricing. The objective of the optimization process is to minimize the congestion cost based on an advanced macroscopic flow theory called the multimodal macroscopic fundamental diagram (mMFD), which can capture the macroscopic traffic dynamics of multimodal transportation systems. In the proposed framework, we develop mMFD-based congestion pricing scheme and incorporate traveler’s behavioral model (i.e. joint departure time and mode choices) with the microscopic traffic simulator. We consider the Tokyo central area as a case study. The simulation results indicate that space allocation of 4.7% for the dedicated bus lanes would be optimal for Tokyo’s network, while the optimal congestion pricing scheme indicates that charges of 900 JPY between 7:30 and 8:00 AM and 300 JPY between 8.00 and 8:30 AM should be levied.
