Thirteen children were killed on London's roads in 2003

Mobile speed cameras will be installed at traffic danger spots during the initiative which coincides with National Autumn Walk to School Week.

Leaflets will also be handed out to children and drivers with advice on how to make the school journey safer.

In 2003 an average of nine children under 16-years-old were involved in road accidents every day in the city.

During this time there were 13 fatalities.

George Galli-Atkinson, whose daughter Livia was killed in a road crash in January 1998, said: "We should all take responsibility in making the roads safe for everyone to help stop other families being devastated by the loss of a loved one."

By working with local authorities, schools and the public we can reduce the number of deaths on London roads. Acting Ch Supt Ian Chappell

Acting Ch Supt Ian Chappell, from the Metropolitan Police, said officers will be looking for dangerous drivers such as those not wearing their seatbelts or using their mobile phones.

"Children are a vulnerable group of road users," he said.

"With the wet weather and the nights drawing in, drivers need to take extra care.

"Children travelling to school in the dark should also take care, cross at well-lit crossings and wear reflective clothing to help them be seen by drivers.
