Just 14 per cent of motorists responded to a traffic survey that caused rush-hour misery in Sunderland.
Tens of thousands of drivers were hit by severe delays during the survey, which was carried out on September 23, leaving Sunderland City Council to apologise to angry motorists.
The council conducted the survey – the first of its scale in the city – to help gather information for plans to improve the city’s road network with a £45m dual-carriageway from the A19 to the Port of Sunderland.
But after distributing 38,589 cards, the authority has confirmed it received 5,635 responses.
The survey was held at five strategic points in the city’s road network as part of Government funding requirements towards the Sunderland Strategic Transport Corridor Phase 3 – a dual-carriageway link between the A19 and the Port of Sunderland.
The survey points were on the Wearmouth and Queen Alexandra bridges, the A1231 Wessington Way, A1290 Washington Road, and the A690 Chester Road.
Despite the response rate, the council said it was in line with expectations and thanked those who took part in the exercise.
Councillor Michael Mordey, the City Council's Portfolio Holder for City Services, said: "Thanks to everyone who took the time and trouble to reply. The council does appreciate it and it is part of this bigger project that can benefit us all in the long-term.
"The returns are in-line with expectations, experiences and similar surveys held by other local authorities.
"Along with the roadside traffic counts, all the information is helping with further planning for this major road improvement scheme. The scheme is part of this council's commitment to improving our city's road network. Thanks again for everyone who took the time to complete the survey."
Works for Phase 3 of the corridor are currently being programmed for a start in 2018 and completion in 2019/20.
