Highlights A kind of multicolor perceptual markings (MCPMs) is introduced for the first time. The MCPMs lead to increases in car-following time and distance headways, and reduction in speed. The MCPMs stabilize the lateral movement of vehicles on the lane. The MCPMs afford the drivers to accommodate their behaviors to a safer car-following status.

    Abstract Perceptual markings on roadways are prevailing countermeasures with substantial effectiveness for accident prevention, and a variety of alternatives and derivatives of them are developed to expect to receive an augmented performance of behavioral intervention and crash risk mitigation. However, the proper use of colors as a way of developing effective and innovative perceptual markings is seldomly recognized in-depth from the perspective of visual perceptual mechanism in behind. Given this, in this study, we introduced a kind of multicolor perceptual markings (MCPMs) pattern, i.e., one red marking follows one yellow marking (“1Y + 1R”), two red markings follow two yellow markings (“2Y + 2R”), and three red markings follow three yellow markings (“3Y + 3R”), and evaluated their effects on longitudinal and lateral driving behaviors and real-time safety benefits in car-following via a series of field investigation on a real-world expressway in China. The statistical analyses of the relative differences of speed ( θ v ), distance headway ( θ d ), time headway ( θ h ), lateral movement ( θ p ), and crash risk ( η mTTC and η DRAC , developed from time-to-collision (TTC) and deceleration rate to avoid crash (DRAC)) suggest that, 1) the MCPMs could lead to substantial increases in car-following time and distance headways, and reduction in speed. The maximum time headway increase (0.61 s), speed reduction (1.42 m/s), and distance increase (3.6 m) were found in the condition of “1Y + 1R” compared with the baseline; 2) the MCPMs stabilized the lateral movement of vehicles on the lane at each observation section, and “1Y + 1R” yielded the best performance of lane-keeping; 3) the MCPMs yielded applaudable real-time safety benefits, which were believed to afford the drivers a better chance to accommodate their behaviors to a safer car-following status. The findings of this study suggest the MCPMs could be an especially applaudable form of perceptual markings, and could also be a critical reference of how to use colors in a better way for developing augmented perceptual markings.
