Dear Mayor,

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

At present, traffic jams have become a major problem in our city every day. The number of private cars has been increasing all the time. What’s more, some drivers disobey traffic rules, thus constantly causing traffic jams.

From my point of view, measures must be taken to solve this problem. First of all, the government should encourage people to use public transport more and at same time limit private cars. What comes next is that more lanes and parking lots should be built. Last but not least, 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,

Li Hua
