目前,我国公路的混合交通状况,是影响运输效率的重要因素。专供汽车行驶的二级公路加辅道,不仅是解决混合交通问题的有效途径,而且是工程造价较低,建设周期较短的建设方案。它可以为交通运输提供通过能力大、经济效益高和安全快速的道路条件。现就对通车一年的大同至塘沽公路倍家造至孙启庄段的观测分析为依据,阐述如下: 大同至塘沽公路大同至孙启庄段,1983年平均汽车交通量755辆/昼夜,混合交通量1534辆/昼夜。1983年底,为解决晋煤外运问题,汽车交通量增加到2026辆/昼夜,混合交通量增加为3780辆/昼夜,尤其是重型车和拖挂车成倍增加,致使公路破坏十分严重。为
At present, the mixed traffic condition of the highway in our country is an important factor affecting the transportation efficiency. The secondary road specially designed for vehicles, the auxiliary lane, is not only an effective way to solve mixed traffic problems, but also a construction project with low construction cost and short construction period. It can provide the traffic with road conditions that are large, cost-effective and safe and fast to pass. Now on the one-year opening of the Datong to Tanggu highway observation and analysis of the times to build section to Sun Qizhuang paragraph as follows: Datong to Tanggu Highway Datong to Sun Qizhuang section in 1983, the average car traffic 755 / day and night, mixed traffic 1534 Day / Night By the end of 1983, in order to solve the problem of the transportation of coal outside Shanxi, the traffic volume of automobiles increased to 2,026 vehicles / day and night, and the traffic volume increased to 3,780 vehicles / day and night. In particular, heavy vehicles and trailers were multiplied, resulting in serious road damage. for
