The possible closure of one of Gungahlin's busiest streets to make the town centre more pedestrian and family friendly was mooted by Labor backbencher Meegan Fitzharris last month.

Options for the area could include a total ban on cars, a new share way space, reduced speed limits for cars of 20 kilometres per hour or night time only access for motorists.

More than 600 people have completed a survey launched by Ms Fitzharris with 75 percent of respondents supporting a permanent ban on cars and the creation of a pedestrian first area.

"It's clear that people want to see change in the town centre, whether that be closing Hibberson Street permanently to traffic, or turning it into more of a shared zone," Ms Fitzharris said.

"Either way, people want to see more feet on Hibberson Street."

The full results of the survey will be presented to the Minister for Roads and Planning Mick Gentleman for consideration when submissions close in mid-October.

So far, close to half of respondents said they would be more likely to visit the town centre if Hibberson Street was more pedestrian friendly.

The proposal comes ahead of the government's planned light rail development, which will include a new terminus stop at the top of Hibberson Street.

The tram line is expected to lead to a pedestrian and tram only zone between Hinder Street and Gungahlin Place East by 2019.

Many responses in favour of the car ban noted the potential businesses for a night economy and improved safety for pedestrians.

"Closing Hibberson Street to traffic would open up the street to a cafe culture, beautify the area and most importantly increase safety for all using the area," one respondent said.

"I think it would an opportunity to create a space for alfresco dining along with a family friendly play area. If the light rail is planned to finish here anyway why not get people used to it earlier?" said another.

But not everyone was supporting of the car ban and some feared the changes would make surrounding roads more congested and dangerous.

"If you have been in Civic during the day time let alone at night it is full of people who just sit around and hang out all day and are quite basically feral," said one respondent.

"I also believe closing the street permanently to traffic can make the area very unsafe, particularly at night," said another. "I would also be concerned about traffic congestion on the surrounding streets if it was permanently closed."

Ms Fitzharris urged Gungahlin residents to consider the benefits of a car ban while the street is closed for construction works between October 13 and December 8.

"If people are unsure about what the street would be like if it is closed to traffic, why not check it out during this period when the underground Marketplace carpark is redeveloped," she said.

"This will be a chance to road-test the closure and see what impact it has on access and the atmosphere of the town centre."

The ACT government will launch more detailed community engagement on the future of Hibberson Street when survey is completed.
