At the reconnaissance stage, the engineer’s task is , by cut and try, to determine which routes deserve further study. Terminals of the road and intermediate points through which it must pass form the primary controls . A unique bridge site or single mountain pass also may become a primary control if no alternative exists . Likewise, for scenic highways , the positions of timbered areas, waterfalls,lakes,and other attractions may be primary controls .Small settements which would be ignored or purposely bypassed in locating principal highways may be primary controls for secondary rosds. Drainage systems, mountain passes, low points in ridges, or swamps in low country, often form secondary controls. Cost factors such as favorable or unfavorable soil conditions, the numbers and sizes of structures, and the amount of excavation and embankment required for satisfactory alignment and grade likewise can be classified as secondary contrils.

在侦察阶段，工程师的任务是，藉着伤口和尝试，决定哪些路径更进一步该得到研究。道路和中间的点完成的它一定通过哪一个的终端机形成主要的控制。如果没有替代选择存在，一个独特桥位置或独身者山途径也可能成为主要的控制。同样地，为风景好的公路，有树木区域、瀑布、湖和其他吸引的位置可能是主要的控制。会被忽略或者在位于主要的公路方面被故意地省略的小 settements 可能是中级的 rosds 控制的提名候选人的预选会。排水制度，山经过，低的国家脊，或沼泽的低的点，时常形成中级的控制。费用因素，像是有利或不宜的土壤，的条件，结构的数字和大小，和大的挖掘和堤防必需的为满意的对准和等级而且能被归类为中级的 contrils。
在多山的国家，以定义明确的高峰会范围，有 usuall 用沿着排水在两边跟随的可能的方法适当的途径。最没有昂贵的和时常直线可能在水流中躺着仅仅上述高水。时常，然而，山谷或峡谷的上升可能超过最大可允许的等级。然后，如果蒸气的等级将被跟随，在旁的峡谷，或与改变角度，额外的车道长度一定在毗连的山马刺上被得到。
