摘要In mountainous cities, as an important part of urban road grade crossings and tunnels, reasonable net distance directly affects urban road construction and traffic operation quality. The definition of the net distance between an urban road grade crossing and a tunnel given light adaptation indicates that drivers must recognize traffic signs, change lanes away from the car's range, and observe safe distance in intersections. By analyzing various factors of demand distance, the urban road grade crossing and tunnel net distance calculation model, and an urban road grade crossing under different running speeds, a reasonable tunnel net distance was proposed. This work provides engineers a reference for similar engineering designs.
Abstract：In mountainous cities, as an important part of urban road grade crossings and tunnels, reasonable net distance directly affects urban road construction and traffic operation quality. The definition of the net distance between an urban road grade crossing and a tunnel given light adaptation indicates that drivers must recognize traffic signs, change lanes away from the car's range, and observe safe distance in intersections. By analyzing various factors of demand distance, the urban road grade crossing and tunnel net distance calculation model, and an urban road grade crossing under different running speeds, a reasonable tunnel net distance was proposed. This work provides engineers a reference for similar engineering designs.
