The speed-change lanes including the acceleration lane and the deceleration lane provide drivers a smooth transition between high-speed lanes and low-speed lanes. Since the light change between the open tunnel section and the dark buried tunnel section, driver’s visual behavior varies a lot. Due to the limitation of the land planning, these two complex road infrastructures integrated in the same section of some road design manuscripts. Therefore, a driving simulator study was conducted in order to validate the safety of such design. The results show that: (1) drivers prefer to change lanes in the open tunnel section rather than the dark buried tunnel section when entering or exiting the high-speed lane; (2) driver’s acceleration behavior is affected by the tunnel when entering the high-speed lane; (3) driver’s deceleration behavior seems to be not affected by the tunnel when exiting the high-speed lane.
