摘要
本研究对公路典型施工区内三种限速措施的效果进行了分析评价,结论表明:单一的限速标志所能取得的效果很有限,不能达到人们预期的效果;相比之下,视错觉减速标线有一定的减速效果,能够使平均速度降低8 km/h;而减速垄的效果则十分明显,使平均速度降低了17 km/h。
The evaluation of three speed reduction measures in highway work zone is conducted in this research. It can be concluded that the effect of the individual speed limit sign is very limited, which can not achieve the desired results, and the three dimensional speed markings take effect to some extent, which can reduce the average speed to 8 km/h,and the effect of speed bump is very obvious,which make the average speed slow down to 17 km/h.
