Hundreds of miles of roads in British town and city centers are being put off-limits to cars as local authorities make radical changes to transportation policies. Measures are also being put in place to make life more difficult and expensive for drivers in hopes that they will abandon their cars and get around by walking, bicycling, or using public transport. The measures include traffic lights that favor pedestrians and cyclists, tough parking rules, and road bumps and rough road surfaces that force cars to go slowly. Incentives for cyclists in some towns include free shower facilities and free areas where parked bikes will be supervised.
