This paper presents a calculating method on the travel speed for urban expressway. Time mean speed and space mean speed are introduced at first. On that basis, the definition on travel speed is given. And then, a five-step calculating procedure is designed. Interesting to note that the expressway should be divided into several sections and delay functions should be calibrated for specific traffic flow states in this research. Finally, a part of expressway (7 km) in Tianjin City is brought as our case. Through calibration, calculation and verification in the case study, this calculating method is illustrated to be effective to estimate the travel speed for urban expressway.
