Problem parkers are making roads close to Bournville College a no-go area, say angry residents.
One of the fed-up householder is Suzanne Mitchell, who lives on The Roundabout Estate.
She blamed the traffic problems squarely on workers and students at the new college.
Mrs Mitchell said the area was choked by parked cars to the extent the only bus service struggles to get through.
“I know it stems from the college because we only have the situation in term times,” she said.
Mrs Mitchell, aged 62, and 71-year-old husband John have lived on the estate for over 30 years and never known it this bad.
She claimed cars straddled pavements, simply because motorists don’t want to pay the £1.50 all-day fee at a nearby public car park.
“I almost knocked someone off their mobility scooter,” said Mrs Mitchell. “It wasn’t his fault, but it wasn’t mine, either.
“Cones have been erected in Tessall Lane but there’s a ribbon of vehicles stretching down to the railway station.”
She added: “I think there will be an accident. Buses have to pull out and emergency vehicles would have difficulties getting through.
“The Roundabout Estate has only a small entrance off the Bristol Road and some of the parked cars from the college in term time are causing a hazard as they are parking on the hill.
“I’ve asked for the help of my MP and local councillor, but haven’t yet got a response.”
The college relocated to the £66 million campus in 2011.
A college spokesman said: “We’d like to thank Mrs Mitchell for raising this matter.
“There is ample parking which is well used in the area around the college with a 500-space car park just across the road.
“We regularly monitor the local roads around our college to check that those staff and students who choose to park locally do so legally.
“We will remind our staff and students again to be a good neighbour and to park considerately.
“We do recognise that there are more vehicles in the area lately and have noticed this at weekends as well as weekdays, due to the vibrant and exciting new developments on the Longbridge town centre site and the high usage levels of Longbridge station.”
