The use of CCTV to monitor bus lanes, during their hours of operation and otherwise, for traffic flow purposes is a matter for the local authorities in whose functional areas the bus lanes are located.
The Road Traffic Acts already provide for the use of cameras to aid enforcement. Under section 81 of the Road Traffic Act 2010, electronic apparatus, including cameras, may be used to provide evidence in relation to offences under a number of provisions of the Road Traffic Acts. Section 35 of the Road Traffic Act 1994 is one such provision, and traffic and parking regulations made under this section set out the requirements governing the use of bus lanes. Section 81 provides the power for cameras and other electronic apparatus to be used to provide evidence in relation to these offences.
