Abstract
The invention relates to the technical field of tunnel traffic safety, and in particular relates to a tunnel vertical curve sight line induction system which is suitable for an expressway tunnel with the speed limit of 60 to 100 km/h and comprises a tunnel vertical curve road section composed of an uphill section, a variable slope section and a downhill section. The induction system for the vertical curve road section of the tunnel comprises a first high beam turning-on mark arranged 200 m in front of the starting point of the uphill section, a second high beam turning-on mark arranged at the starting point of the uphill section, belt lines and reflectors arranged on the tunnel side walls of the uphill section and the downhill section, flexible sight line induction columns which are arranged on the two sides of the uphill section road section and the two sides of the downhill section road section, and the height of the flexible sight line induction columns is gradually changed; the system further comprises a U-shaped LED self-luminous contour belt which is arranged on the whole vertical curve road section, fan-shaped reflective strip sets which are arranged on the side walls of the tunnel of the variable slope section, and variable slope point marks which are arranged at variable slope points. The segmented arrangement is adopted, and is easier to understand and execute by a driver according to a driving task and a driver factor theory.
Description
technical field [0001] The invention relates to the technical field of tunnel traffic safety, in particular to a tunnel vertical curve line of sight induction system. Background technique [0002] For the vertical curve section of the tunnel, the driver will experience rapid transitions of uphill, transition, and downhill in a short period of time. The driver's sight distance on the slope section is poor, and the special environment in the tunnel easily leads to the driver's judgment on the slope feeling. Deviation, and the vertical curve section is short, there will be a situation that the driver has entered the next section before fully adapting to the uphill section, which will cause the driver to have greater physical and psychological discomfort when driving on the vertical curve section. The transformation of the slope and slope type of the vertical curve section of the tunnel is likely to cause changes in the driver's driving psychology, and the speed of the vehicle o...
