Parking restrictions at Portishead Marina may become a permanent feature in a bid to help manage traffic in the area.
Double yellow lines were painted along parts of Newfoundland Way and Phoenix Way earlier this year.
The experimental move followed mounting concern about people parking along Newfoundland Way and Phoenix Way, restricting access for larger vehicles - including buses which use the route.
Earlier this year buses had to be diverted as they could not get along Newfoundland Way to badly parked cars - leaving the marina without a service.
The buses are run by First and are relied upon by many living in the marina development, which is home to a large number of elderly people and young families.
The parking issues have also caused problems for other large vehicles such as refuse and recycling trucks which have been unable to get along the routes.
The experimental traffic order came into force earlier this year, with the experiment expected to finish in May.
However council chiefs have said it is continuing and some elements of the scheme could become permanent.
North Somerset Council executive member for highways Councillor James Tonkin said: “We are continuing with the experiment regarding the parking restrictions around the marina.
“We are continuing to evaluate what works and what does not work.
“It may be that other measures need to be added while some may have to be taken away.
“We will look what amendments may be needed before any scheme becomes permanent.”
In the past the authority had targeted its wardens to Newfoundland Way.
And there was also talk of installing CCTV cameras in a bid to catch those parking badly.
Inconsiderate parking has long been a bug bear of residents and visitors to the marina.
On a number of occasions parked cars have caused problems right across the development with large vehicles unable to make their way through the streets.
Concerns have also been raised about emergency vehicles being to access homes and businesses.
