Cameras to monitor congestion have been placed around the Scott Arms Junction, with data from the cameras being used for the Sprint bus route.
The devices have been placed on Pages Lane, Newton Road, Rocky Lane and Walsall Road, along with others in the area.
Cameras are also reportedly on Booths Farm Road and Beeches Road as well as other locations in the vicinity.
A spokesman for Transport for West Midlands said: “These cameras are monitoring and measuring congestion at the busy Scott Arms junction and the surrounding road network.
“This data will be fed into the design for Sprint rapid bus route along the A34 through the busy Scott Arms junction.
“It will also be used in the development of further measures to cut congestion, improve traffic flows and reduce pollution as part of our ongoing investment in the region’s key route network.”
Residents in the area took to Facebook to raise their concerns – with some believing them to be speed cameras.
Sue Bushall said: "What's going on with the cameras on Beeches Road and Walsall Road so many – any reason?"
Els Ward said: "Loads of grey cameras have gone up overnight round the Scott Arms."
Other residents asked why everyone was "panicking" – even if they were speed cameras.
Sue Ball said: "They are for traffic surveys. Why is everyone panicking, if you drive correctly it doesn’t really matter what they are."
