It follows an incident on Wednesday morning last week when three children were lucky to escape serious injury when a car hit them as they tried to use a pedestrian crossing on Cary Street (Main Road 217) outside Toronto Public School, on the corner with Bay Street.

The road carries 16,000 vehicles a day and despite the school having an absolute 50 metre frontage, the section is not a 40 kph school zone.

The Greig children, Curtis, 8, Ruby, 7, and Lily, 5, sustained minor injuries when they were hit as they stepped onto the road after the pedestrian light went green.

The RTA says there is no school zone on Cary Street because it has no direct access to the school.

Toronto town co-ordinator and Cary Street resident Keryl Fedrick said she feared more accidents would occur, as a parking lane along Cary Street ended near the school, leaving pedestrians closer to traffic that included trucks.

She said flashing lights at least should be installed at the pedestrian crossing.

"It makes you think - what has to happen before they will do something about it," she said.

Ms Fedrick said she agreed with Lake Macquarie MP Greg Piper's description of the road as a "dog's breakfast".

"It's getting busier and busier," she said.

"It's just a mess during peak hour."

Asked if the minister supported a school zone, a spokesman for Mr Borger said the -4%RTA had been asked to urgently complete the review of roads near the school.

"As a priority, the RTA is arranging to upgrade the visibility of the traffic lights at the Bay Street intersection to newer technology LED [light emitting diode] displays," he said.

There had been 56 recorded crashes on the main road between the Boulevarde and Bay Street from 2005 to 2009. Three were speed-related and none was fatal.

The spokesman said a decision on whether to go ahead with upgrading the road would be made after planning work worth $500,000 was completed.
