The reasonable laying of colored pavement at the entrance of highway tunnel is significantly important for improving visual warning and ensuring driving safety. Based on the traffic characteristics at the entrance of the highway tunnel, the current common laying types of colored pavement at the entrance of the tunnel are summarized after a large number of investigations. According to the requirements of speed transition, and based on the model of driving perception-behavior, perspective principle, and the flash rate principle, the design suggestions of colored pavement laying position, length, and stripe spacing are given. From the perspective of brightness transition, two methods of increasing safety distance and theoretical verification of design scheme are proposed. Finally, starting from the laying requirements of the color pavement at the entrance of the tunnel, the main problems faced by the current colored pavement design at the entrance of the tunnel are discussed in order to provide reference for the design and further research of colored pavement scheme.
