For the sake/purpose of solving the traffic problem, the local government held a meeting recently, at which many experts had a full discussion and put forward valuable suggestions.

　　First, they pointed out that the cause of serious traffic jam was due to the increasing number of private cars. They held/maintained that raising the tax rates of using cars was one of the most effective measures to limit this trend and people should be encouraged to make full use of public transportation.

　　The second leading / contributing factor that the government couldn’t neglect was the poor road conditions. Narrow streets, inadequate traffic signs and false signal lights added to the trouble. It was suggested that old houses should be pulled down to make way for the traffic.

　　What’s more, every day we could hear the endless running vehicles roaring through the narrow streets filled with anxious passing crowds. New regulations should be practically adopted to separate them for the sake of safety.

　　All the experts present agreed that steps should be immediately taken to solve the problem effectively。
