Problems solved by technology

[0003] The object of the present invention is to solve the problem of insufficient safety of trucks on the continuous downhill section of the expressway, to provide a special slow speed lane for trucks on the continuous downhill section of the expressway, to realize the coordinated control of large trucks and small cars on the continuous long downhill section, and to limit the speed of the truck. Increase the driving speed, reduce the probability of brake failure, and improve the safety of trucks driving on downhill roads

Abstract

A slow-speed lane dedicated to freight vehicles on a continuous downhill section of an expressway, including a diversion transition section, a buffer zone, a steady speed zone, and a merge transition section; The gradient section is for the vehicle to change to the buffer zone; the buffer zone includes the sign visual recognition section and the deceleration section, the sign visual recognition section is for the vehicle driver to read the sign and react, and the deceleration section is for the vehicle driver to take braking measures to slow down to a steady state. The speed limit in the speed zone; the stable speed zone is the road section where the delivery vehicle runs stably under the speed limit; the merge transition section is the road section for the vehicle to accelerate and change back to the main line of the expressway. The invention travels at low gear and low speed in the stable speed zone, thereby alleviating the temperature rise trend of the brake hub, maintaining the temperature of the brake hub within a safe range, reducing the probability of brake failure, and finally improving the safety of the truck on the downhill road section .

Description

technical field [0001] The invention belongs to the field of road safety, and in particular relates to a slow-speed lane specially used for freight vehicles on a continuous downhill section of an expressway. Background technique [0002] In recent years, with the continuous improvement of my country's highway network, the focus of highway construction has gradually shifted to the western mountainous areas. Due to the limitation of complex terrain and geological conditions, more continuous long downhill road sections have been formed. When large trucks drive on long downhill roads, it is easy to use the service brake for a long time, causing the temperature of the brake to continue to rise, resulting in the phenomenon of "thermal recession" of the brake hub, which seriously threatens driving safety. However, there is a large gap between the leading models in longitudinal slope design, and there is a contradiction that vehicles and roads are not coordinated. In view of the in...
