用“多点摄像法”对长春市的2个路段交通流进行了实地调查。通过数据处理，给出了车队离散过程中的多点流量图式以及多段的车速分布。用实际观测数据所得的流量图式与TRRL的流量图式进行对比，分析异同。还对车辆行驶速度及行驶时间分布进行了拟合，分析了各离散模型的适用范围。最后对车队离散进行计算机仿真，得出了满意的结论。

在我国城市交通管理中，对城市信号交叉口处机动车、自行车和行人的混合交通流的有效组织是交通通畅运行的关键。在交通调查的基础上，利用数理统计方法分析城市信号交叉口自行车及行人的到达与释放规律，提出城市信号交叉口自行车及行人的到达分布模型，对城市信号交叉口自行车流的释放饱和流率、释放速度和行人步速进行标定，并对信号交叉口自行车流及行人的交通特性形成原因进行分析。研究结果可应用于城市信号交叉口混合交通控制及管理。

In terms of the similarity between a road network and a circuit network, this paper demonstrates that Kirchhoff's current and voltage laws observed in the circuit can be employed in the traffic assignment of the road network. Inspired by the more consummate circuit theory, we put forward a new idea and method of traffic assignment. A set of models is formularized by means of multiobjective nonlinear planning theory, and the solutions are found using MATLAB. An example is provided to prove the feasibility of the new traffic assignment model.

Car-following models describe how one vehicle follows the preceding vehicles. In order to better model and explain car-following dynamics, this paper categorizes the state of a traveling vehicle into three sub-processes: the starting (acceleration) process, the car-following process, and the stopping (deceleration) process. The starting process primarily involves vehicle acceleration behavior. The stopping process in volves not only car-following behavior but also deceleration behavior. This paper regards both the stopping process and the starting process as spring systems. The car-following dynamics during the starting process and the stopping process is modeled in this paper. The parameters of the proposed models, which are represented in the form of trigonometric functions, possess explicit physical meaning and definitive ranges. We have calibrated the model of the starting process using data from the Traffic Engineering Handbook, and obtained reasonable results. Compared with traditional stimulus-response car-following models, this model can better explain traffic flow phenomena and driver behavior theory.
