What are the causes of traffic jams in big cities? Give solutions.
Answers
A variety of serious problems caused by excessive road traffic in many big cities have concerned the public. It is essential to find out the root causes behind this phenomenon and work out some solutions.
The increase in population in these big cities is one of the major causes. Every year in China, millions of people migrant to big cities like Shanghai, Beijing and Guandong for better lives. They are attracted by more job opportunities, higher educational levels and more enjoyable lifestyles there. This increase consequently adds to the traffic burdens in these cities. To tackle this problem, I suggest the government encourage citizens to live and work in their hometowns rather than go to big cities. To do this, the government should invest more on less developed areas to improve the infrastructure and thus living standard there. They should also make the best use of the advantages in these less developed areas to create more job opportunities. For example, in some mountainous regions where there are beautiful scenic spots, the tourism industry can be developed.
Another major cause of this problem is the growing popularity of private vehicles. As the rich have more disposable incomes, convenience and speed have become their priority. But since private cars can carry far fewer passengers than a bus can, there will be a sharp rise in road traffic. Therefore, buses and other public transport should be made more popular. The government should invest more in building subways and sky railways, and providing more buses. They should also strive to bring the cost of public transport down to make it economically more attractive.
The above are my analysis of this problem along with my proposals to address it. I hope they can be helpful.
The truth is that traffic congestion is caused by multiple causes and here they are not in the order of importance.
1- Too many cars for the roadway due to inadequate mass transit options or other reasons.
2- Obstacles in the road causing a blockage and merger. These can be any of the following:
Double parking
Road work
Lane closure due to utility work
Road narrowing down
An accident
3- Traffic signals out of sync many times on purpose or occasionally when the computers are malfunctioning.
4- Inadequate green time
5- Too many pedestrians crossing not permitting cars to turn
6- Too many trucks on the road due to inadequate rail freight opportunities
7- Overdevelopment in areas where the mass transit system is already overcrowded and the road system is inadequate.
