Analysis on Recognition Sight for Main Line Restricted Exit of Expressway

摘要：

To determine recognition sight for main line restricted exit of expressway, the paper used car theory and ergonomic principles to analyze recognition sight of different design speed for the main line restricted exit. The paper proposed recognition sight of main line restricted exit with different design speed of 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 expressway were limited by the terrain and position, the exit located in the main line restricted place, the exit of expressway should been strengthen by security measures to ensured the safety of main line restricted exit for expressway.
