车辆超载并不是一个新现象，它对道路路面损坏、道路安全以及温室气体排放的不利影响已被广泛讨论。虽然在较发达国家的情况下已经说了很多，但在发展中国家，关于车辆超载的讨论却不多。本研究建立了一个发展中国家车辆超载的范围和程度。一半的三轴卡车被发现超载，超载程度高达法定重量限制的101% ！通过建立一定行驶速度下货车停车距离与车辆总重的关系，讨论了货车超载对安全的影响。2轴、3轴和4轴卡车的实际超载数据与停车距离的对比说明了情况的严重性，需要相关机构制定全面有效的策略。关键词：道路安全，车辆超载，交通事故，动态称重，停车距离
The phenomenon of vehicle overloading is not new and has been discussed in relation to the adverse effects on road pavement damage, road safety and GHG emission. Although much has been said in the context of the more developed countries, there has not been much discussion on vehicle overloading in developing countries. In this study, the extent and degree of vehicle overloading in a developing country is established. Half of the 3-axle trucks were found to be overloaded and the degree of overloading is up to 101% of its legal weight limit! The effect of truck overloading on safety is discussed by establishing the relationship between truck stopping distance and gross vehicle weight for a certain travel speed. Comparison between actual overloading data for 2-axle, 3-axle and 4-axle trucks and the stopping distance illustrates the gravity of the situation which needs a comprehensive and effective strategy from the relevant agencies. Keywords: Road Safety, Vehicle Overloading, Traffic Accidents, Weigh-in-Motion, Stopping Distance
