基于運行車速的山區(qū)高速公路長大縱坡交通安全研究
[Abstract]:Mountain areas are steep and roads tend to form long and large vertical slopes. Because the vehicle performance indexes are different, the running speed of the vehicle will differ greatly, and the speed of the truck will be low, which will cause the small car running in the rear to overtake and change the road frequently, thus causing the traffic accident. In order to keep the vehicle running stably, the forced braking in the long downhill section leads to the deterioration of the performance and even the failure of the brake. The safety of the vehicle is affected. So it is significant to study the safety of long longitudinal slope to improve the driving safety of mountain road. In this paper, based on the analysis of domestic and foreign related research results, combined with field research, the traffic safety of long and long longitudinal slope sections is studied by non-accident rate method. In this paper, the VISSIM simulation model is established to study the running condition of uphill slope. With the help of VISSIM, which is based on slope, slope length, traffic volume and vehicle mixing rate, simulation tests are carried out on the driving safety of climbing slope, and the influence of four parameters on the driving safety is obtained. The analysis resulted in improvement measures. In this paper, by analyzing the driving characteristics of two kinds of representative vehicles and getting off, using the method of multivariate nonlinear regression, the speed prediction models of two kinds of representative vehicles in long downhill section and slope, slope length and radius are established. The prediction value of the running speed is calculated, and the downhill section is classified according to the degree of danger, and the dangerous section is determined by the grade of danger degree, which provides data support for the study of traffic safety and reflects the present situation of safety and puts forward the solution. The conclusion of the paper can give some reference value to the design of the mountain road growth slope in the future, at the same time, it has certain guiding value to the safety improvement measures of the long longitudinal slope.
