摘要

摘要: 将城市交通路网抽象为二维连续的平面，提出一个考虑城市住房分布的二维连续型动态交通分配模型，并估计了城市交通污染物排放水平.该模型中，住房分布影响交通需求，出行者根据用户最优准则选择出发时间和路径，可以用于模拟城市交通运行的动态演化过程，得到密度、速度和流量等物理量.采用基于车辆速度和加速度的微观污染物排放模型VT-micro估计城市交通CO₂动态排放水平.基于三角网格，采用有限体积法、投影算法和相继平均法进行数值求解，给出一个数值算例验证了模型和算法的有效性.

Abstract: A 2D continuous dynamic traffic assignment model considering housing distribution was proposed, and then the traffic-related emissions were estimated. In the model, the traffic demand is influenced by housing distribution, and travelers choose departure times and routes according to the dynamic user-optimal principle. The model can be used to describe the dynamic traffic and obtain the traffic density, velocity and flow. A speed and acceleration-based microscopic emission model VT-micro was applied to estimate the traffic-related CO₂ emissions. The finite volume method, the projection method and the successive average method were constructed based on triangular meshes. A numerical example of a city with a single CBD was presented to demonstrate the effectiveness of the model and the numerical algorithm.
