What are the characteristics of highway transportation |
Time:2015-11-21 Source: Views:3203 |
1, flexible, adaptable: because the road transport network in general than the railway, waterway network density should be ten times, the distribution is wide, so the road transport vehicles can be "everywhere, there is no time". Highway transportation in the time of the mobility is also relatively large, the vehicle can be scheduled at any time, shipping, the link between the time is shorter. Especially highway transportation has a strong adaptability to the number of passengers and cargo. The truck has a small (300t ~ 1t), which can be transported independently by a single vehicle, as well as by a number of vehicles, which is especially important for the rescue, relief work and military transportation.
2, gate to gate "direct transport: due to the small volume of the car midway generally do not need to dress up, in addition to along the outside of the wider distribution of network operation, but also left the road network into factories and enterprises, rural field, urban residential, which can take the passengers and goods from the departure gate direct delivery to destination gate." door to door "direct transport. This is one of the characteristics of other transport modes, which can not be compared with the highway transportation.
3, in the medium and short distance transportation, delivery speed is faster: in the medium and short distance transportation, the highway transport can be achieved "door to door" direct transport, midway does not need to be unlucky, ride can be directly to the passenger and freight to be. Therefore, compared with other modes of transport, passenger and goods in transit time is shorter, faster delivery.
4, the original investment is less, the capital flow faster: road transport and rail, water, air transport, the need for simple fixed facilities, vehicle purchase costs are generally low, so, investment and easy to invest, investment recovery period is short. According to the relevant data show that in normal operation, the investment of highway transportation can turn 1 to 3 times per year, and the railway transportation will need 3 to 4 years to turn a time.
5, master the technology of the vehicle driver is more easy: with the train driver or the pilot of the plane, the car driver technology is easier to master, the driver of the quality requirements are relatively low.
6, smaller volume, higher transportation costs: at present, the world's largest car is GM production of mine dump truck, more than 20 meters long, weight 610t, load of 350t around, but still trains, ships are much less than; due to vehicle load is small, running resistance than iron Road 9 to 14 times, consumption of fuel and higher prices of liquid gasoline or diesel. Therefore, in addition to the aviation transportation, is the cost of automobile transportation had the highest.
7, continued to run less: according to the relevant statistics show that, in all modern means of transportation, and the average distance of highway is the shortest, running continuously is poor. If the average distance is 55km 1998 China highway passenger, freight 57km, railway passenger 395km, freight is 764km.
8, low security, pollution environment: according to historical records, since the birth of the car, has swallowed about 30000000 people's lives, especially in 1990s, the number of people died in the car accident has increased dramatically, an average of about 500000 per year. This figure is more than the number of deaths from AIDS, war, and tuberculosis. The vehicle exhaust and noise caused by the vehicle also seriously threaten human health. It is one of the biggest sources of pollution in the big cities.
