6、nt traffic, and the changes to be expected in these factors. 为了确定交通需要，公路工程师收集和分析关于已有设 施的物理特征，当前的交通量、交通分布和交通特性，以及 在这些因素上要做的变化等信息。 The highway engineer must determine the most suitable location, layout, and capacity of the new routes and structures. 公路工程师必须确定最合适的位置、布局和新线新结构 的通行能力。 Frequently, a prelim
7、inary line, or location, and several alternate routes are studied. 通常，要仔细考虑初步的线形，或定位，以及几条可选 择的路线。 4 土木工程专业英语 Highway Engineering The detailed design is normally begun only when the preferred location has been chosen. 按惯例，只有当更好的线位被选择以后，才开始详细设 计。 In selecting the best route, careful consideration is g
8、iven to the traffic requirements, terrain to be traversed, value of land needed for the right-of -way, and estimated cost of construction for the various plans. 在选择最佳线路时，要仔细考虑交通需求、要经过的地 形、道路用地所需土地的价值、以及不同方案的预估施工造 价。 The photogrammetric method, which makes use of aerial photographs, is used extensive
9、ly to indicate the character of the terrain on large projects, where it is most economical. 利用航空拍摄技术的摄影制图方法被广泛地利用起来显 示大型工程的地形特征，在大型工程中采用这种方法是最经 济的。 5 土木工程专业英语 Highway Engineering On small projects, ground-mapping methods are preferred. 对于小型工程，就宁可选择地面制图方法。 Financing considerations determine whether t
10、he project can be carried out at one time or whether construction must be in stages, with each stage initiated as funds become available. 资金方面的考虑决定着工程是否能一次实施或者必须分 阶段施工，每个阶段都只有当可以获得资金的时候才开工。 In deciding the best method of financing the work, the engineer makes an analysis of whom it will benefit. 在确定
11、为工程集资的最好的方法的过程中，工程师要分 析工程将对谁有利。 Important highways and streets benefit, in varying degrees, three groups: users, owners of adjacent property, and the general public. 重要的公路和街道在不同程度上对三组人群有利：使用 者、邻近房产的所有者、以及全体公众。 6 土木工程专业英语 Highway Engineering Users of improved highways benefit from decreased cost of t
