Analysis on Recognition Sight for the Main Line Restricted Exit of Expressway
To determine recognition sight for the main line restricted exit of an expressway, this paper used the car theory and ergonomic principles to analyze recognition sight of different design speeds for the main line restricted exit. The paper proposed recognition sight of the main line restricted exit with different design speeds for the ramp and main line. The results showed that, for the new expressway, the exit of the main line should avoid the use of threshold of recognition sight. For the existing expressway, when the exits of the expressway were limited by the terrain and position, the exit located in the main line restricted place and the exit of the expressway should have been strengthened by security measures to ensure the safety of the main line restricted exit for the expressway.
