Dear Mayor，

I'm writing to give some suggestions to improve our city's transportation.

At present，traffic jams have become a major problem faced by most people of our city every day.The number of private cars has been increasing.What's more，some drivers disobey traffic rules，causing traffic chaos.All this often results in traffic jams.

In my opinion，measures must be taken to solve this problem.First，the government should encourage people to use public transport more and at the same time limit private cars.Second，more lanes and parking lots should be built.Third，it's important to educate the public to obey traffic rules.

I would appreciate it if you could take my suggestions into consideration.I'm looking forward to your reply.

Yours sincerely，
