摘要
在分析治超给石太高速公路所带来的影响的基础上,探讨了治超的意义及合理方法选择。建立在治超前后交通调查数据基础上,采用统计方法分析了货车车型变化特点;采用当量轴载换算方法分析了车辆对路面作用的变化;建立在典型路面构造基础上分析了道路养护成本的变化;建立在社会成本最低与公平基础上分析了治超的合理方法选择:证明了超载治理是正确的,但当前方法存在漏洞,成本偏高,长效激励机制不足。表明治超对公路部门具有巨大的直接效益,对汽车工业良性发展具有推动作用,今后应在保证不增加使用者总体负担基础上,将计重收费作为公路超限治理的主要政策选择。
The meaning of overload treatment and rational method are discussed on the basis of analyzing the influence of overload treatment bringing to Shi-Tai Expressway. On the basis of analyzing traffic investigation data before and after overload treatment, a statistical method is adopted to analyze the characteristics of truck style changes, the equivalent axis load convert theory adopted to analyze the changes of function of vehicles on road surface to analyze the changes of the road maintenance cost on the foundation of construction of typical road surface and rational method selection based on the lowest social cost and fairness. It proves that overload treatment is correct, but loophole exists in the method at present, such as the cost is somewhat high and the long incentive mechanism is insufficient, howere overload treatment has enormous direct benefits to the highway department and gives an impetuse to the benign development of auto industry. For the future, the charge on weights method should be regarded as a major policy choice of freight overload treatment based on the guarantee without increase in users' gross obligations.
