Street construction
Due to the rapid growth in the number of cars growing plights garages and car parks. There is a garage and parking is at present not completely satisfy the needs of car owners. The greatest difficulties in selecting sites for both short-and long parking lots occur in places of mass-concentration: in the business districts, near the stadiums and train stations, the industrial and commercial centers.
Research specialist transport in most other developed countries found that at sites in central business districts in the hours of "peak" collects about 85-90% of the cars. Studies carried out in the U.S., show that during peak periods only 5-15% of the vehicles are in motion, and the rest are in car parks, the sidewalks or continue to move in search of parking spaces. The concept of urban car ownership based on the need of massive, well-organized public transport, the presence of which in some cases makes it unprofitable and inefficient use of private cars.

The base is usually done in order to transfer the load from passing cars in dispersed form in the road bed. The top cover of the roadway can be made of gravel to bitumen impregnation, asphalt, concrete, portland cement-impregnated soil or gravel. Shoulder is needed to support the pavement and also serve for an emergency stop. Drainage devices are necessary for removal of external water and stormwater flows.
