Local Taryn Langdon has presented an online petition to the ACT Legislative Assembly calling for upgrades including better signage; upgrades to the nearby intersection of Sulwood Drive and Mannheim Street; and better cycling infrastructure.

The carpark at Mount Taylor has no clear entry or exit and nearby Sulwood Drive or foothpath for pedestrians.

"The carpark there is fairly ad hoc and it's coming off an 80 km/h road. People just sort of decide to turn whenever they like to get into the car park," Ms Langdon said.

As the road becomes an "East-West Link for cyclists", Ms Langdon said space should be made for them too.

"We need to call for a bit of positive action so we don't witness a genuine tragedy up there," she said.

Ms Langdon said Mount Taylor is becoming a more popular but a number of near misses have alarmed residents.

Ms Langdon and other locals frequently discussed the intersection until finally deciding to "stop complaining" and take action.

"I think if you speak to anyone that has driven through the area or walks up Mount Taylor or tries to cycle through the area, they all express a concern of safety," she said.

The petition also calls for improved lighting and a bin at the car park, as well as changes to Mannheim Street to slow traffic.

Labor MLA Chris Steel has officially thrown his support behind the petition by sponsoring it after his own concerns over traffic in the area.

"I live nearby and walk my dog Pickles up Mount Taylor most evenings and have noticed the increase in cars parked around the mountain on Sulwood Drive," Mr Steel said.

"I am happy to assist the community to work constructively with government to improve safety and ensure more Canberrans can enjoy Mount Taylor."

Canberrans can read and sign the petition by visiting epetitions.act.gov.au. The petition closes in late November.

The petition is not legislation but will be presented to the assembly for the record; if it gains 500 signatures will be passed to relevant directorates for consideration.
