在大型城市的交通态势模拟中，宏观模型相比于微观模型，具有效率高，物理意义明确的优点，但缺乏车辆在各个时刻的细节描述。为了使宏观模型的交通模拟的显示更加直观，结合微观模型的更新方式，提出了基于宏观模型的可视化方法。通过道路上的车辆初始密度得到所有车辆的初始位置和速度；根据宏观路段速度更新车辆信息，使得宏观路段密度值与微观车辆所构成的车辆流密度相符。该方法能够给出宏观模型中车辆在各个时刻的运动情况，并添加了微观上的细节。以实例证明了该方法的可行性。

In the simulation of large cities’traffic situation, the macroscopic model compared to the microscopic model, has advantages of high efficiency, clear physical meaning, but lack of vehicles in a detailed description of each moment. To make the macroscopic model of traffic simulation display more intuitive, combined with the update method of micro-scopic model, this paper puts forward the visualization method based on the macroscopic model. The vehicle’s initial posi-tion and speed are obtained by the road vehicles’initial density;then the vehicle information is updated according to the macroscopic road speed, to make the density of macro-sections consistent with the microscopic vehicle current density. This method can give the vehicles’motion of each time in the macroscopic model, and add the microscopic details. A case study of setup planning is presented to verify the feasibility of the method.
