What measures could be taken to solve the traffic jam?

Since the technology has been developed for a couple of decades, people tend to enjoy their lives more conveniently and comfortably. Following this trend, the number of people who have a car has been increased. And now, we can always can see a big traffic jam anywhere in the city. Thus, I want to suggest some measures which might be helpful for the government to solve this problem.

Firstly, imposing high taxes for car owners could be one of alternatives. The Car owners would like be likely to give up their ownership if the burden becomes heavy. They may be willing to use public transportations such as buses and a the subway.
Secondly, it could be effective to develop the transportations. As mentioned earlier, people pursue a comfortable life. Although the car is expensive, it seems that people do not hesitate to buy a new one for living in comfort. Therefore, if they feel more comfortable to use buses or a the subway than using a private car, this can help to decrease the traffic jam.
Finally, strengthening regulations related with car ownerships can be taken as a measure. It would be a good idea to regulate or limit standards of qualification for driver’s licenses. I heard that in some other countries, a boy barely 16 years old can drive a car! Lower standards for driving can cause a large amount of car demand. Even worse, a car accident would be occurred by some drivers not enough qualified enough to drive with driving.

As the a result, it seems that making people prefer to use convenient transportation, imposing a high tax for car owners and tightening regulation on a cars might be solutions to help reduce the traffic jams reduce. With these measures, I hope the number of cars would decrease gradually and in the end, we will hardly see roads crowded by cars.
