Madison Bird, a grade 5 pupil at Mount Ridley College, first managed to push Hume Council to appoint four school crossing supervisors on the streets surrounding her school.

Madison's other feat - getting the council to install two extra speed humps in Dianne Avenue - has led to a significant reduction in traffic speeds in the area. A council traffic survey, released last week, shows that although daily vehicle numbers on the street jumped to 1523 in February compared with 1357 in March last year, the average speed in February dropped to 44km/h compared with 56km/h.

Madison said she was happy that her street was safer due to the added speed humps, but she wants more action taken against hoon drivers.

"The speed humps work fairly well, but I think some of the smaller streets in the area still have problems with hoons.

"You can still hear them [hoon drivers] doing doughnuts and other silly things, which is pretty scary."

Craigieburn has been ranked No.8 on the list of Melbourne's top 20 hoon hot spots. Since July 2006, 112 vehicles have been impounded by police in Craigieburn.

Madison said she would continue her push for improved community safety, but already she has a new campaign - improving her school bus timetable.

"I'll write to the council to let them know that we only have three minutes to get on the bus after school finishes at 3.20pm," she said. "We have to rush to get out of class and I get worried that I'll miss the bus."

Craigieburn councillor Ross Spence said Madison's efforts might inspire other young residents to push for positive changes in the community.

"Madison is two for two at the moment and she is really making a difference for the people of Craigieburn," Cr Spence said.

Acting Senior Sergeant Peter Robertson, of Craigieburn police, said any action by locals to reduce hoon driving was a good thing. "Hoon driving continues to be the focus of police efforts and it's great that local residents [like Madison] are assisting police efforts."
