Abstract

To reduce the influence of the irregular connection sections at the tunnel exits on traffic safety and improve the safety management of tunnel exits, this paper deeply analyzed the traffic flow characteristics of each characteristic section in the connection sections based on the measured data of the irregular connection sections at the exit of Guanzhou Tunnel in Guangzhou Higher Education Mega Center. Meanwhile, it explored the shortcomings in traffic design and management, and proposed specific traffic improvement schemes, with safety evaluation methods provided. A simulation model was built by employing the VISSIM traffic simulation platform, and after model calibration and accuracy verification, the driving status before and after the improvement of the tunnel connection sections was simulated. Additionally, by conducting in-depth analysis of simulation data, the average potential accident risk value and speed difference of each vehicle on the road section were utilized to evaluate road section safety. Based on this, delay and queuing length indicators were leveraged to carry out efficiency evaluation on special road sections, which was then adopted to comprehensively evaluate the optimization effect of the improvement scheme. The evaluation results indicate that there is significant room for improvement in the traffic operation scheme of the connection sections at the exit of Guanzhou Tunnel. The improvement scheme proposed in this paper can improve the driving safety and traffic operation efficiency of the connection sections at tunnel exits, and provide theoretical support for the improvement of traffic safety management in irregular connection sections of the tunnel exits.
