1、机动灵活，适应性强：由于公路运输网一般比铁路、水路网的密度要大十几倍，分布面也广，因此公路运输车辆可以“无处不到、无时不有”。公路运输在时间方面的机动性也比较大，车辆可随时调度、装运，各环节之间的衔接时间较短。尤其是公路运输对客、货运量的多少具有很强的适应性，汽车的载重吨位有小(0.25t～1t左右)有大(200t～300t左右),既可以单个车辆独立运输,也可以由若干车辆组成车队同时运输，这一点对抢险、救灾工作和军事运输具有特别重要的意义。
1. Flexible and adaptable: Because the density of highway transportation network is more than ten times higher than that of railway and waterway network, and its distribution is wide, highway transportation vehicles can be "everywhere and everywhere". Highway transportation is also more flexible in terms of time. Vehicles can be dispatched and shipped at any time, and the connecting time between various links is shorter. Especially, highway transportation has a strong adaptability to the number of passengers and cargo traffic. Vehicles with small load tonnage (about 0.25t-1t) and large load tonnage (about 200t-300t) can be transported independently by a single vehicle or simultaneously by a fleet of several vehicles, which is of great significance to rescue, disaster relief and military transportation.
2、可实现“门到门”直达运输：由于汽车体积较小，中途一般也不需要换装，除了可沿分布较广的路网运行外，还可离开路网深入到工厂企业、农村田间、城市居民住宅等地，即可以把旅客和货物从始发地门口直接运送到目的地门口，实现“门到门”直达运输。这是其它运输方式无法与公路运输比拟的特点之一。
2. It can realize "door-to-door" direct transportation: because of the small size of automobiles, there is no need to change in midway. Besides running along the wider road network, it can also leave the road network and go deep into factories, enterprises, rural fields, urban residential areas and other places. That is to say, passengers and goods can be transported directly from the gate of the origin to the gate of the destination, so as to realize "door-to-door" direct transportation. This is one of the characteristics that other modes of transport can not be compared with road transport.
3、在中、短途运输中，运送速度较快：在中、短途运输中，由于公路运输可以实现“门到门”直达运输，中途不需要倒运、转乘就可以直接将客货运达目的地，因此，与其它运输方式相比，其客、货在途时间较短，运送速度较快。
3. In the medium and short distance transportation, the transportation speed is faster: in the medium and short distance transportation, because road transportation can achieve "door-to-door" direct transportation, passengers and cargo can reach their destination directly without reverse transportation or transfer. Therefore, compared with other modes of transportation, the passengers and cargo have shorter travel time and faster transportation speed.
4、原始投资少，资金周转快：公路运输与铁、水、航运输方式相比，所需固定设施简单，车辆购置费用一般也比较低，因此，投资兴办容易，投资回收期短。据有关资料表明，在正常经营情况下，公路运输的投资每年可周转1～3次，而铁路运输则需要3～4年才能周转一次。
4. The original investment is small and the capital turnover is fast. Compared with the ways of railway, water and air transportation, the fixed facilities needed for road transportation are simple, and the purchase cost of vehicles is generally low. Therefore, the investment is easy to start and the payback period of investment is short. According to the relevant data, under normal operating conditions, investment in road transportation can be turned around 1-3 times a year, while railway transportation needs 3-4 years to turn around once.
5、掌握车辆驾驶技术较易：与火车司机或飞机驾驶员的培训要求来说，汽车驾驶技术比较容易掌握，对驾驶员的各方面素质要求相对也比较低。
5. It's easier to master the driving skills of vehicles: compared with the training requirements of train drivers or aircraft drivers, the driving skills of vehicles are easier to master, and the quality requirements of drivers are relatively low.
6、运量较小，运输成本较高：目前，世界上最大的汽车是美国通用汽车公司生产的矿用自卸车，长20多米，自重610t，载重350t左右，但仍比火车、轮船少得多；由于汽车载重量小，行驶阻力比铁路大9～14倍，所消耗的燃料又是价格较高的液体汽油或柴油，因此，除了航空运输，就是汽车运输成本最高了。
6. The transportation volume is small and the transportation cost is high. At present, the largest automobile in the world is the mine dump truck produced by General Motors Corporation of the United States, which is more than 20 meters long, 610 tons of dead weight and 350 tons of dead weight, but still much less than that of train and ship. Because of its small load, the driving resistance is 9-14 times greater than that of railway, and the fuel consumed is also liquid gasoline or diesel oil with higher price, so, except for that, the truck has less load. With air transportation, the cost of automobile transportation is the highest.
7、运行持续性较差：据有关统计资料表明，在各种现代运输方式中，公路的平均运距是最短的，运行持续性较差。如我国1998年公路平均运距客运为55km，货运为57km，铁路客运为395km，货运为764km。
7. Operational sustainability is poor: According to relevant statistical data, the average distance of highway is the shortest among all kinds of modern transportation modes, and the operational sustainability is poor. For example, in 1998, the average distance between highway and passenger transportation was 55 km, freight transportation was 57 km, railway passenger transportation was 395 km and freight transportation was 764 km.
8、安全性较低，污染环境较大：据历史记载，自汽车诞生以来，已经吞吃掉3000多万人的生命，特别是20世纪90年代开始，死于汽车交通事故的人数急剧增加，平均每年达50多万。这个数字超过了艾滋病、战争和结核病人每年的死亡人数。汽车所排出的尾气和引起的噪声也严重地威胁着人类的健康，是大城市环境污染的最大污染源之一。
8. Safety is low and the environment is polluted. According to historical records, since the birth of automobiles, more than 30 million people have been devoured. Especially since the 1990s, the number rouruanji.37ix.com.cnmuliao.37ix.com.cnmuliaog.37ix.com.cnzhidaijiz.37ix.com.cn yawenzhi.37ix.com.cnwufangbuf.07858.netof people who died in automobile accidents has increased dramatically, averaging more than 500,000 a year. This number exceeds the annual deaths of AIDS, war and tuberculosis patients. Vehicle exhaust and noise also seriously threaten human health, and is one of the largest sources of environmental pollution in large cities.
