401.Section 280 amends the Road Traffic Reduction Act 1997 (not yet in force), which places a duty on boroughs to assess road traffic levels, to set targets for reducing traffic levels or the growth of these levels, and to report to the Secretary of State.  Reports prepared by a London borough, under the provisions of the 1997 Act must take account of the Mayor’s transport strategy and the borough’s local implementation plan. The Mayor may give directions or issue guidance to London councils on matters on which the Secretary of State may issue guidance (provided that the guidance or directions do not conflict with the Secretary of State’s guidance). The councils must comply with the Mayor’s directions and have regard to his guidance. When a London borough sends a report to the Secretary of State under the 1997 Act, it must send a copy of the report to the Mayor.
