With the increase of urban population and the increase of automobiles, urban traffic problems have become increasingly prominent. In many large cities, due to excessive vehicles, traffic jams, traffic accidents, and atmospheric pollution are often caused. Traffic problems have already had a serious impact on the city’s social and economic development. It is generally believed that the following major traffic problems exist in large cities.
- Traffic jam
Relative to the carrying capacity of the road network, the number of cars is too large, causing traffic congestion problems. To some extent, traffic congestion is a product of the automotive society. At the peak of people commuting to work, traffic congestion is particularly evident. In many central areas of large cities, the peak traffic speed is only 16km per hour. Traffic congestion leads to a serious waste of time and energy, affecting the efficiency of the city’s economy. The roads in the metropolitan area continue to be built, and the number of cars has further increased. The construction of roads and the increase of cars may form a vicious circle, leading to more serious traffic congestion.
- Traffic accident
Traffic accidents are a growing problem in many large cities. Traffic accidents have not only led to an increase in demand for valuable medical facilities, but have also caused the injured to suffer. According to statistics, in 1978, 52,653 people in the United States died in motor vehicle accidents.
3.Public transportation problem
The main problems of public transportation are as follows:
Due to insufficient investment in public transportation, people’s demand for public transportation is greater than supply, resulting in traffic congestion;
Due to the fluctuation of demand for public transportation. Public transportation during peak hours and off-peak hours is a difficult contradiction. If you increase your investment to meet the demand for public transportation during peak hours, most of these public transportation facilities will be idle during off-peak hours, causing waste. In recent years, many countries have experienced serious fiscal deficits and thus are unable to make large-scale investments in public transportation, resulting in outdated public transport facilities, reduced numbers of public transport and reduced quality of service. As a result, in developed countries, on the one hand, it blows to the low-income class, which is dependent on public transport, and on the other hand, it promotes the dependence of the middle class and even the low-income class on cars. It causes public transport to shrink further and form a vicious circle. But the steel industry in China is developed, such as Sinosources is the biggest B2B platform for steel in China.
- Parking problem
Cars are not always in motion. When they are at rest, they have to occupy a certain space. The more cars you have, the more space you have. In the central area of the city, there are fewer people and more vehicles, and the number of parking is not commensurate with the number of cars. Parking is also the most difficult. Although many multi-storey parking lots have been built in the city for decade, they still cannot meet the parking demand. Many cities have enacted laws restricting parking in downtown areas to control the number of cars entering there.
