计重收费在2006年被证实是十年来最有效的“治超”策略,随着实施计重收费高速公路覆盖面的扩大,普遍性的超载正在成为历史,长途货运车辆大型化成为明显趋势。半挂牵引车在重卡中的份额在2006年迅速增加。2006年前三个季度,半挂牵引车销量同比增长超过50%,极大地说明了计重收费对车辆大型化的影响。 Weight-charging was proven to be the most effective “super-control” strategy in 10 years in 2006. With the expansion of toll-free expressway coverage, the prevalence of overloading is becoming history. The large-scale conversion of long-distance freight vehicles has become a clear trend . The share of semi-trailer tractors in heavy trucks increased rapidly in 2006. In the first three quarters of 2006, the sales of semitrailer trailers increased more than 50% YoY, which greatly illustrated the impact of toll charging on large-scale vehicles.
