- Summary:
- In order to reduce traffic accidents and losses in long downhill sections of expressways, giving drivers reasonable prevention and control means of information induction can improve the safety of long downhill sections. The location of the accompanying information service of the driver's vehicle terminal and the rationality of the intervention information are worth studying. This study takes a high-speed long downhill road as an example, divides the risk level of the long downhill road based on the road safety risk index model, and verifies it with the help of driving behavior data. Secondly, three coverage schemes of sensing devices are designed according to the results of risk classification, and the HMI interface of accompanying information service is designed according to the different coverage degrees of sensing devices. Finally, a driving simulation experiment was carried out based on the driving simulator, and the speed control level, psychological comfort level, operational stability level and risk awareness level were selected to compare the impact and effect analysis of the three prevention and control schemes, and the optimal accompanying information service scheme was selected with the help of TOPSIS comprehensive evaluation method. The results show that the early-warning prevention and control information provided by the full-coverage accompanying service has a positive effect on the safety prevention and control of long downhill road sections.The results can provide theoretical support for the location and number of sensing devices in the practice of long and steep downhill projects, and provide a new perspective for the design of accompanying service terminals
