公路技术等级

中小城市的道路网普遍存在着公路网技术等级低、服务水平差等问题。

Furthermore , highway network mostly is the trouble of technical grade and service low .

公路桥梁技术状况等级评定的准确性和客观性依赖于桥梁细部构件的权重。

The veracity and objectivity of the existing highway bridge assessment are depended on the weight of the bridge components .

但是我国公路网存在的技术等级低、密度低、服务水平不高等问题，导致其仍不能满足汽车运输的需要。

However , the highway network exists problems of low technology grade , low density , low service level , leading it fails to meet the needs of automobile transportation .

但是与国家和省级干线公路不同，县乡公路主要由技术等级在二级和二级以下的公路所构成。

However , the rural road is different from main roads of state or province level in that it is mainly composed of roads whose technical degree is of or under the second degree .

隧道的修建缩短了公路的里程，提高了公路路线的技术等级，改善了线性和交通运输条件，提高了车速，缓解了公路通行能力不足的矛盾。

The construction of the tunnel shortens the road mileage , improves the level of road technical , improves the linearity and transportation conditions , improve the speed and alleviates the problem of insufficient traffic capacity of roads .

公路里程迅猛发展，路网结构进一步完善，公路技术等级和路面等级不断提高，各类公路工程投资快速持续增加。

The highway mileage rapid development , the road network structure further consummates , the road technical class and the road surface rank enhance unceasingly , each kind of highway engineering investment continues to increase fast .

在公路规划建设中交通量预测是一个重要的环节，是确定公路建设项目的技术等级、工程规模以及经济评价的主要依据，是建设项目决策的重要依据。

The traffic volume prediction is one of the important parts in highway planning and construction is the main parameter to determine the technical classification , the scale of project and the economic evaluation and is the important reference in decision-making of highway construction .
