Changes to road traffic law will facilitate the introduction of new methods of traffic law enforcement especially those that permit automatic and unattended detection by using a camera to record the offending motorist. The handbook contains a description of the technical requirements to be met for consideration of type-approval of traffic light cameras and associated equipment which are intended to photograph automatically vehicles which do not stop when traffic signals are red. Type-approval will be required when such prescribed devices are used for law enforcement. The handbook is intended to be a reference for manufacturers wishing to develop or sell existing products to the police service in Great Britain. The handbook contains not only a list of technical requirements but also guidance on the procedures to be followed in seeking type-approval. The second edition adds requirements for combined traffic light and speed cameras, interfacing with traffic signals that use LED (Light Emitting Diode) arrays and use for enforcing signals at level crossings. The required accuracy for any displayed speed data has been revised in line with changes in the latest edition of the Speedmeter Handbook. Note: Any requirement for goods or materials to comply with this specification shall be satisfied by compliance with traditional procedures of manufacture of a Member State of the European Union where these are the subject of a written technical description sufficiently detailed to permit assessment of the goods or materials for the use specified, provided that the proposed standard, code of practice, technical specification provides, in use, equivalent levels of safety, suitability and fitness for purpose.
