大型露天矿交通标志设置位置研究

Study on Location Setting of Traffic Signs in Large Open-pit Mines

大型露天矿常用车辆在驾驶方式、车型尺寸、标志尺寸等方面均与传统公路标志存在一定差异,传统公路标志设置标准难于满足露天矿常用车辆。为解决矿区标志设置的问题,本文沿用公路标志设置位置计算方法,通过理论分析确定静态盲区是限制交通标志位置设置的主要因素。并通过分析结果建立了包含矿区特点的单个路侧标志设置计算方法。并以禁令标志为例,通过该计算方法求得了在满足车辆制动条件、驾驶员可视条件下标志牌的设置位置,证明了计算方法实用可行。

The vehicles used in large-scale open-pit mines are different from traditional road signs in terms of driving style,vehicle size,and logo size.It is difficult setting standards of traditional highway signs to meet the common vehicles in open-pit mines.In order to solve the problem of sign setting in mining area,the location calculating method for the road sign is used,and through theoretical analysis,it is determined that the static blind zone is the main factor limiting the location setting of the traffic sign.According to the analysis results,a calculation method is established for the setting of single roadside sign considering the mining area features.Taking the ban mark as an example,the calculation method is used to obtain the setting position of the signboard to ensure the driver's visual line under the vehicle braking condition,which proves that the calculation method is practical and feasible.
