为解决农村公路以较大坡度接入主线公路时所产生的交通安全隐患,提出在农村公路紧接主路路肩的地方设置一段缓坡引道,以方便农村道路车辆停车让行。根据停车受力分析,确定引道的坡度;根据停车视距的计算原理确定缓坡引道的长度。
In order to solve the traffic safety problems arising from the access of the rural road to the main highway with a relatively large slope, it is proposed to set up a gentle slope near the main road shoulder of rural roads so as to facilitate the parking of rural road vehicles. According to parking force analysis, determine the approach road slope; according to the principle of calculation of parking line of sight to determine the length of gentle slope approach.
