以高速公路收费系统数据库为主,收费站抽样调查为补充,分析了中国高速公路网运输状态。分析结果表明:与2006年相比,2007年度高速公路网货运密度同比提升了12.30%;小型客车(小于等于7座)客运密度同比提升了18.90%;汽车列车完成货物周转量的66.20%,货运车辆空车走行率为18.97%,超限30%以上的货车比重为6.81%;小型客车完成旅客周转量的38.12%,轿车平均每车乘坐2.50人;中国高速公路网运输的特点是货车比重大,货车行驶量占总行驶量的37.52%,这种情况加重了道路负载,也容易出现事故,尤其在山区高速公路上;高速公路网大中型客车运输市场已经受到来自铁路的挤压,在今后几年中,这种现象还将持续。
Taking the toll collection system database as the mainstay and the toll station sample survey as a supplement, the status of expressway network transportation in China was analyzed. The results of the analysis show that compared with the same period of 2006, the density of expressways net increased by 12.30% over the same period of last year; the passenger density of small passenger cars (less than or equal to 7) increased by 18.90% over the same period of last year; that of motorized trains completed by 66.20% The empty passing rate of vehicles was 18.97%, the proportion of trucks exceeding the limit of over 30% was 6.81%; the small passenger vehicles accomplished 38.12% of the passenger turnover and the average car was 2.50 people per vehicle; the expressway network transportation in China featured large proportion of trucks , Truck driving accounted for 37.52% of the total traffic, which aggravated the road load, but also prone to accidents, especially in the mountain highway; large and medium-sized bus transportation market has been squeezed from the railway in the future In a few years, this phenomenon will continue.
