Abstract:
In order to improve the level of operation security in dangerous road sections, the speed should be slowed down to a safe range. The forms and design parameters of the deceleration markings was compared and optimized. Based on the mechanism of optical illusion deceleration markings in dynamic environment, the parameters of the chevron markings were analyzed and the space calculation method was proposed. The different design parameters were combined together to execute the orthogonal experiment. The simulation test and the actual road test were carried out to verify the actual deceleration effects. The results show that the actual deceleration is effected significantly by the design parameters, and good deceleration effects are subject to reasonable parameters design. The deceleration effects of variable spaced deceleration markings are better than the equal ones. 7 tabs, 2 figs, 10 refs.
