N2 - According to statistical data, risky merging driving behavior has taken adverse impact on traffic safety, and it widely exists in the ramp connecting section of urban expressway. Risky merging driving behavior can be divided into three types considering the difference in merging speed of vehicle, and the statistical characteristics of risky merging are analyzed based on video data. Because different traffic flow parameters have different effect on risky merging, rate of risky merging will rises with the higher traffic volume and lower traffic speed of main road. Results show that the appropriate length of acceleration lane can reduce rate of risky merging, and the security risks on risky merging comes from traffic conflicts initiated by merging gap selecting of ramp vehicle. Furthermore, one times of the most dangerous directness type leads to 3.29 times of traffic conflicts.
