Abstract
This paper mainly studies the travel time impedance functions of urban transportation networks including two parts: the uninterrupted flow function and interrupted flow function. On the basis of uninterrupted flow's speed-flow relationship, we propose a piecewise method to research on its impedance function. In the interrupted flow function, links and intersections are considered separately. Each kind of turn delay at signal intersections is estimated through the delay function of HCM2000. The impedance functions are used in a macroscopic simulation model to prove the feasibility in practice.
