The number of cameras catching out drivers in bus lanes is set to quadruple as part of a £2 million transport project.

The funding will see 21 new cameras installed in Brighton and Hove including eight along a two-mile stretch of Preston Road heading into the city centre.

Motoring and civil liberty groups claimed the cameras were designed to “rake” millions of pounds from motorists rather than bring in safety benefits.

But the council said the cameras would make drivers think twice about driving in bus lanes while the total package would help get the city moving more freely.

The cameras will cost £315,000 in total with further investment on puffin crossings, bluetooth receivers gathering traffic data for the council and new computer systems.
