The junction sections of bridges and tunnels can shorten the mileage of mountainous area freeways and improve the accessibility greatly, but it also causes serious accidents easier. This paper using the example of Xi-Han expressway, analyzes the causes and characteristics of traffic accidenst in the junction sections of bridges and tunnels byusing experiments to measure the speed of the vehicles coming in and out of the tunnel, the illumination intensity inside and outside the tunnel and the surface adhesion coefficient. It applies software to obtain the limiting scope and calculates the safe following distance when vehicles enter and exit the tunnel in order to supply reference dates for drivers to improve the safety, and suggest that designers lower the speed of the junction section of bridge and tunnel in mountain expressway.
