Residents say traffic lights being introduced at a busy town junction will lead to delays.
Lights are to be installed at the Midland Road junction with Senwick Road and Elsden Road, near to Wellingborough Train Station.
A spokesman for Northamptonshire County Council said highways works were secured as part of planning permission for the Eastfield Urban Quarter development, but members of Castle Area Road Safety Action Group (CARSAG) say these will cause delays and take up residents’ parking spaces fought for to stop commuters parking there.
CARSAG chairman Allan Blackman said: “The biggest flaw I can see is when the station is emptying, there’s a lot of traffic going across Midland Road.
“The lights would have to allow for these cars to escape the station, otherwise it’s a huge tailback in the station itself. If it’s timed for them to escape at various points of the day, traffic will be stopped from flowing.”
The county council spokesman said: “We have a responsibility to facilitate these works and we cannot refuse to enter into the required agreements to enable the developer to comply with the planning consent.
“The works will go a considerable way to mitigate existing traffic flow problems, as well as predicted issues if no development and no works were undertaken.”
The spokesman added: “We are working closely with the developer, the Borough Council of Wellingborough and Network Rail to move the Stanton Cross development forward.
“But in the meantime, if nothing was done in anticipation of the Stanton Cross scheme, the junction would continue to operate poorly, and the situation would be put under further pressure as a result of the Eastfield Urban Quarter development.”
