b'provided to a particular standard without subsidy in relation to England, and in Scotland. The provisions for tendering are repealed in relation to Scotland but still apply, albeit slightly amended, in relation to England. A non-metropolitan county can take such measures as appear appropriate to promote the availability of public passenger transport services (other than subsidised services) and the operation of such services and to promote the convenience of the public (including the elderly and the disabled) in using such public passenger transport services. This is subject to a proviso that it should not inhibit competition between service operators. Any non-metropolitan county or district and Transport for London (or any of its subsidiariessee Greater London Authority Act 1999) can enter into agreements with each other under which the council (or LRT) undertakes to contribute towards any expenditure incurred by the other party in providing subsidies for public passenger transport services (section 65). A passenger transport executive may provide, maintain, repair and operate bus stations and associated facilities at any place in or in the vicinity of its area. A district council which ceases to have power to run bus undertakings by virtue of section 66 of the 1985 Act retains power to maintain, repair and operate bus stations and associated facilities provided by it under its former powers. Charges must be reasonable and an executive or local authority must not discriminate against any public service vehicle operator or class of operators (sections 81 and 82 of the 1985 Act). Concessionary schemes may be established for the blind, disabled, children, elderly and others specified in. Section 106 applies to any Integrated Transport Authority, Passenger Transport Authority, or Passenger Transport Executive, any combined authority, the council of any county of England and Wales, the council of a London borough or the Common Council of the City of London, or any council in Scotlandamended by Local Transport Act 2008. All these authorities have power to make grants to assist the provision of transport facilities for the disabled, or to support revenue expenditure incurred in providing services (or associated facilities) other than those for which a public service vehicle operators licence is required. Authorities responsible for securing the provision of public passenger transport services, local education authorities and authorities responsible for social services must co-operate with each other to secure in the interest of council taxpayers, the best value for money from their expenditure on public passenger transport (section 88 of the 1985 Act). Generally, for anyone interested in bus deregulation issues, concessionary fares, subsidies and grants, some excellent research papers are available from the House of Commons library, which clearly and concisely chart the legislative provisions governing this complex market to date. Road user charging and the workplace parking levy 11.5 The most serious congestion problems in most towns and cities are associated with peak commuting. Car use is influenced by the availability of free or relatively cheap workplace parking. The principal aim of road user charging and the workplace parking levy (WPL) is to provide an incentive to employers and educational establishments to discourage car commuting and use alternative modes of transport (including car-sharing). 130'
