However hard they try to solve the problem, all of the world’s large cities suffer from traffic problems. All of them were not planned to cope with so many vehicles, so the streets are narrow and there is not enough space for parking. A number of different solutions to this problem have been suggested, but none of them has been completely successful. For example, many cities try to discourage the use of private cars in the centre, but even so it is impossible to keep the traffic away.
    As many large shops, offices, hotels, railway stations, etc. are in the centre of the city, there will always be a need for buses and taxis and some private cars. An obvious answer is to move the hotels, offices and large stations out of the city centre. It would be impossible to move all of them, but it would still make the situation better. The new areas would have plenty of parking and public transport, so they would have no problems now found in the old city centre.
