This paper presented an experiment work on AnChu expressway in Yunnan province,to change the standard 4-lane expressway with subgrade width of 26m into 6-lane by redrawing the pavement marking.The experiment results show that the capacity has been increased,with traffic delay caused by stopped vehicles reduced,particularly more convenience for road maintenance work.However,there was the problem of the visibility of the roadside sign,which should be resolved for safety.The author discussed the issue in detail of the solution.
