WHEN I returned to York 12 years ago, I discovered Bootham Crescent, which I remembered from my youth as empty save for the occasional double-deck bus and the Saturday football crowds, had become a rat-run.

At that time movement was somewhat restricted by a solid line of commuters' cars on both sides of the street on Monday to Friday and a few double-parked delivery vehicles. The institution of a residents-only parking cleared the road overnight and created a first class racetrack. Grossly excessive speeds were commonplace.

Building humps has cured the problem. I cannot remember the last time I saw or heard a car travelling at excess speed in Bootham Crescent. I cannot produce statistical data of vehicle numbers and velocities to corroborate these assertions, but I have no doubts.

Negotiating a humped street is simple: set a speed at which the hump can be taken comfortably and stick with it.

It is not necessary to brake for each individual hump and accelerate away. Freewheeling over the hump can help.
