Open publisher page 1 citations

Abstract

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.
