摘 要：
As the basis for urban transport planning, urban transport demand forecast determines the structure of urban traffic network. Urban traffic demand forecast is usually divided into four stages: traffic occurs, traffic distribution, mode split and traffic assignment. An important issue in the traffic assignment is how to determine the road traffic impedance. Traffic impedance is the important parameters to perform traffic assignment and road network planning. Research on the impedance function, in essence, means to determine the relation between travel time and road traffic or conditions. In this study, the actual traffic characteristics of the main road in Hohhot city is used to determine the parameters of impedance function, which refers to the U. S. federal highway administration impedance function.
