Research on design speed of TER (truck escape ramp) was carried out in order to make it more cost-effective and safer. The data of 9 TERs of Yuanmo Expressway has been collected. Back analysis method was brought forward and adopted to analyze the speed of out-of-control vehicles entering arrester bed. According to distribution of vehicle speed data, the speed of vehicles losing braking capabilities that met a probability were obtained, which could be used to determine TER design speed. The result also showed that 99 percent of vehicles' speed was lower than 102.2 km/h, which was much lower than the speed of 130 km/h introduced internationally. The TERs designed by using this result has opened to traffic for one year. No traffic accidents occurred yet caused by improper settings of TER.
