Abstract: Aiming at the problems in venture evaluation of toll expressway, we analyze the characters of the investment venture on the expressway in China. Basing on the standalone risk evaluation model of toll expressway investment and the index system of venture evaluation that we have built and using The Analytical Hierarchy Process and The Fuzzy Synthetic Evaluation Method, we built up a Fuzzy Synthetic Evaluation model of expressway investment venture Then, it was applied to evaluate Tianjin section of the expressway connecting Beijing and Shenyang.，and make some comparisons.

Key words: toll expressway, standalone risk evaluation model, fuzzy synthetic model, the analytical hierarchy process method, venture evaluation
