One of the traffic problems in our big cities is that there are alot of people.There are too many vehicles on the road.Many roads are narrow and bumpy.There are accidents everyday.There are no wild animal running across the road.Many peopele ride their bikes dangerously.I hope, pedestrians will be more conscious in traffic.

 Like many other big cities in the world,our big cities also have some trafic problems.Firstly,too many people are using the roads so there're too many vehicles.Secondly,many roads are narrow and bumpy.Finally,traffic accidents happen everyday because many young people ride their bikes or motobikes dangeroustly.For road safety,I think every road users should strictly obey trafic laws and soon have good solutions to these traffic problems
