Analysis of Refinement and Upgrade of Traffic Safety Facilities at Level Crossing of Ordinary National and Provincial Highway
Based on the refinement and upgrade project of traffic safety facilities at the level crossing of National Highway G240 and Provincial Highway S526 in Yingde City,this paper conducted an in-depth investigation into the common design deficiencies and unreasonable aspects in the channelization at the level crossing of ordinary national and provincial highway in China.Addressing issues such as unclear vehicle turning trajectories,ambiguous right-of-way allocation,and poor sight distances,this paper adopted a strategy that involved meticulous inspection,evaluation,and analysis during the design phase,subsequently proposing corresponding refinement and upgrade plans.Utilizing VISSIM simulation technology,effectiveness of these proposed the refinement and upgrade plans were analysed.Finally,this paper developed a minimal upgrade plan that save construction costs while maximizing safety benefits,providing valuable insights for similar level crossing of national and provincial highway upgrade projects.
