公路平面交叉渠化方法

Channeling Measure of Highway in Grade Crossing

综合国内外渠化方法,特别是在公路等车带、渠化岛的设计中,根据叉口处行车轨迹及标线,提出了等车带及渠化岛几何尺寸的计算方法,该方法结合公路等级及设计速度,在叉口处合理设计渐变段,达到车道轨迹顺适性的目的。

This paper refered to varied channeling measures at home and abroad, especially in the design of strip waiting for vehicle and channeling island. The calculation method of geometrical dimension about the strip and island was put forward, according to the trochoid of wheel and marking at the grade crossing, the level of highway and the design speed of highway. Meanwhile, for the gently running of vehicle, the method also considered the transition portion at the crossing in the design.
