济菏高速公路货车载重特征分析

Analysis of Characteristics of Truck Loading on Jinan-Heze Expressway

根据收集整理的济菏高速公路货车的出口时间、车货总质量、车辆总轴数、超限率等数据，研究讨论了货车交通量、货车载重特征的总体、轴型、时间分布规律。结果表明，月平均日货车交通量11月最大，2月最小；货车载晕与其轴数有关，济菏高速公路上79．13％的货车是二轴和六轴货车，车货总质量主要分布在27t以下和49t以上；49t以上的超限货车交通量占总超限货车交通量的81．01％；超限货车交通量高峰时段是20：00～5：00，此时段43t以上货车交通量比例明显大于其他时段；91．82％超限货车的超限率在20％以内。

In terms of exit time, total vehicle rate of Jinan-Heze Expressway trucks collected, distribution and time distribution of truck traffic weight, the total number of vehicle axle and over-size the paper describes the overall distribution, axle type volume and truck load characteristics. It is shown that.monthly average daily truck traffic volume reaches its maximum level in November, and the minimum level in February; truck load is related to the number of its axle; 79.13% of the trucks are two and six axis trucks; the total truck weight is mainly distributed at below 27 t and above 49 t on the Jinan-Heze Expressway; 81.01% of total over-size truck traffic volume is the truck over 49 t; the peak period of over- size truck traffic volume is 20：00-5.-00, for the ratio of truck traffic 43 t above this period is significantly greater than other periods; and the over-size rate for 91.82%over-size truck is less than 20%.
