Abstract

The invention relates to the technical field of road traffic safety facilities, and particularly relates to a clover leaf type interchange exit direction sign system. The system comprises a way-directing pre-notice sign used for reminding a driver of the distance of a front exit ramp and reminding the driver to pay more attention to complete related driving tasks, a way-directing warning sign used for forcibly reminding the driver that the driver approaches the exit ramp and prepares to act, a way-directing action sign used for guiding the driver to be located at the exit ramp position and must take related driving actions to drive out of the exit, a way-directing notice sign used for reminding the driver of azimuth information at the ramp node so as to help the driver to check whether a driving path deviates or not, a way-directing verification sign used for reminding the driver to perform final verification on a driving path, a forecasting and warning sign used for forcibly reminding the driver that the driver is close to a right-turn large curve and prepares to act, and an action sign used for guiding the driver to be located at the right-turn large curve and must take related driving actions to drive into the right-turn large curve.

Description

technical field

[0001] The invention relates to the technical field of road traffic safety facilities, in particular to a cloverleaf-shaped interchange exit guide sign system. Background technique

[0002] The cloverleaf interchange is an important node in the high-grade highway network, which plays an important role in the transformation of traffic flow among the main highways. It has the characteristics of many entrances and exits, complex driving routes, large traffic flow, and fast vehicle speed. , is the key position of the driver's route selection. The complex traffic driving environment makes the exit of the clover-leaf interchange a high incidence of traffic accidents, and the reasonable setting of the guide sign system is one of the important factors affecting the traffic efficiency and traffic safety of the clover-leaf interchange. A reasonable road sign system can induce drivers to obtain road traffic environment information efficiently, accurately, and in a time...
