与沿海和东部地区相比较 ,西部地广人稀 ,车流量小 ,经济欠发达 ,修建公路的资金筹措比较困难。因此在西部大开发中 ,建设公路的标准不能盲目攀比 ,而要适宜科学。建设标准的制定要通过对今后 1 0至 1 5年的交通量预测 ,经过科学论证 ,需要什么等级的公路就修什么等级的公路。 Compared with the coastal areas and the eastern region, the western region is sparsely populated, the traffic flow is small, the economy is underdeveloped, and the financing of road construction is more difficult. Therefore, in the large-scale development of the western region, the standards for building highways can not be blindly complied with and should be suitable for science. The construction of standards to pass through the next 10-15 years of traffic volume forecast, after scientific demonstration, what level of road repair what level of highway.
