The optical illusion deceleration marking is one of the commonly used speed control measures. In this research, the authors analyzed operating speed and trajectory of motor vehicle at intersection where optical illusion deceleration marking is installed. Quantitative and qualitative evaluation on effect of optical illusion deceleration marking is conducted. Results showed that optical illusion deceleration marking would help to reduce operating speed and average speed by 5-10km/h, to regulate motorcycle driver behavior, and to reduce speed difference, so that driving safety is ensured. Optical illusion deceleration marking is suitable for accident prone road sections on two-lane highways which main vehicle types are passenger car and motorcycle.
