We welcome your decision to publicise the subject of a 20mph city (Oxford Mail, June 13).

Through our contacts, locally and in other regions, we are aware of a growing desire for streets and public places to become more people-friendly.

This trend is now reflected in the transport policies of both the Government and Opposition.

Slowing traffic is the first step in making our communities safer and quieter places for people to get about by foot, bike and bus.

Research shows that lower speeds reduce fuel consumption in a wide range of cars.

The arguments for a blanket 20mph limit in all built-up areas, rather than the present hotchpotch of different speeds in adjacent stretches, are very convincing, both in terms of cost and in reducing confusion for drivers and other road users.

We look forward to Oxford taking the lead in introducing a simple and cost-effective system that will enhance the city for all of us.
