Road transport is one of the most common forms of transport on the planet. He has many not only varieties, but also applications. Even those who do not travel anywhere still use vehicles indirectly, because goods are delivered to stores by them too.

Instructions

Step 1

The words "car", "car" most often mean a vehicle owned by a private person. Whether to have it is a personal matter for everyone, since owning it involves quite significant expenses: for fuel, maintenance, storage, fines, taxes, etc. But the main thing is that in such a car, the internal energy of the fuel is very irrationally spent. Per person, moving "from point A to point B" even in a small car will require noticeably more fuel than if it covers the same distance, for example, by bus or metro.

Step 2

If there are several passengers, the total consumption increases slightly, so traveling in groups is somewhat more rational. This is clearly shown by such a calculation. The engine power of a small car is about 70 kW, with four passengers, each has 17.5 kW, with one - all 70. In a bus with a 200 kW engine and 50 passengers, each of them has only 4 kW. But this does not mean that if you have a car, you need to get rid of it immediately. You can drive not every day, but only when there are no traffic jams, and the distance needs to be covered considerable. Or when you need to deliver a heavy load, such as a refrigerator. You can simply not drive in winter, again, on days of heavy traffic jams, use intercepting parking lots.

Step 3

The bus is also a very common form of transport and the most common form of public transport. Slightly inferior in environmental friendliness to a trolleybus and a tram, it has such an advantage as autonomy: it does not require equipment of roads with wires or rails. Bus engines in most cases run on inexpensive types of fuel: diesel fuel and methane (the only exceptions are minibuses, and even then not all of them). Together with a more rational consumption of this fuel, this factor makes the bus very economical. In the cost of a bus ticket, fuel costs account for only a few percent, the rest is the salaries of drivers and service personnel, spare parts, depreciation. But even so, it is much more profitable for a passenger to ride it than a taxi or his own car, especially when using a ticket.

Step 4

Official vehicles make up only a small percentage of urban transport, so it has little effect on both the environmental background and traffic jams. But he plays a huge role, because without him many processes in the city would have frozen, seemingly imperceptible as long as they proceed without interruptions. For example, moving goods, patrolling the streets. Also, it is this type of transport that most often gets to the place of destination, doctors, specialists of utilities, etc. Special types of vehicles are used in road maintenance, mining, agriculture, airport maintenance, and military affairs. We can safely say that thanks to the official vehicles we are well fed, healthy, safe, and in the courtyards of our houses in the evenings lights are on.

Step 5

It is difficult to imagine sports without vehicles. Sports transport drivers, called pilots, participate in interesting competitions that attract many spectators. And in other sports, in addition to such an obvious role as the delivery of athletes, vehicles also play auxiliary roles, for example, during the repair and preparation for competitions of stadiums, skating rinks, etc.
