Research on Parameter Calibration between Travel Time and Traffic Demand Oriented on Macro and Micro Inter-Validation

There are two main urban transport analysis methods: the micro analysis and the macro analysis. Macro analysis primarily discusses the system composition from the perspective of system long terms and overall optimization, which mainly provides scientific planning for decision-makers. However, the micro analysis mainly analyzes the three parameters such as flow, speed, and density of traffic flow. Urban transport is a complex technical engineering system with strong sociality. Therefore, the two methods should be closely linked and mutually restrained. This paper makes an effort on this linkage. Firstly, speed is selected as the connecting parameter of micro-macro level planning. Then, the paper introduces the detailed steps of parameter calibration between travel time and traffic demand increments based on VISUM. It also illustrates this concept with a real integrated traffic and transportation planning program of Madrid, Spain. Finally, feasibility and practicality of this idea can be drawn from the results.
