| Two elements of urban expressway construction timing, which were the timing of startup of expressway and the construction sequence of expressway network were put forward. The dilemma that current urban expressway construction was lack of scientific decision-making basis was pointed out. The experience of urban expressway construction arrangement in typical domestic cities were summarized. Then, the factors affecting the timing of expressway construction startup were analyzed, and a factor model which based on gross domestic product, population scale, urban area, vehicle ownership et al was proposed with corresponding decision criteria. Then, the influencing factors of the construction sequence of the expressway network were also analyzed. Following the quantitation of influencing factors, an urgency model which based on land development (renewal) index, expressway functional impact index, traffic demand index, implementation condition index and construction capital index was proposed with corresponding decision criteria. In the end of the paper, Jiaxing expressway network was taken as an example to explain the models and corresponding decision criteria.
