The Irish Road Haulage Association has called on the Minister for Transport, Mr Brennan, to show that a school transport management strategy will be operated at the start of the new school year next week.
The association has also asked that the Departments of Transport, Education and Finance introduce plans to change the way parents bring their children to school.
"There should be incentives for parents to arrange for alternative modes of transport for their children. School transport management can provide financial savings to schools and parents, help reduce parking and traffic problems, reduce pollution and provide safety and health benefits," IRHA president Mr Éamonn Morrissey said last night.
"The trucks get the blame for causing all the traffic but the last two months have been beautiful," he said. "Come Monday morning it's going to be 10 times worse, especially in the city area."
"Our members have been talking about it all week, saying how bad it's going to be next week when they're stuck in traffic," Mr Morrissey said. "The days of walking your children to school are long gone. There are cars abandoned on both sides of roads near schools now."
The suggestions put forward by the IRHA include promotion campaigns to encourage parents to reduce car travel to schools, evaluating the use of non-mechanised modes of transport, improving cycle and pedestrian lanes.
Walking "school buses" have been suggested, whereby a parent walks a group of students to and from school. Car-sharing for parents and staff was also proposed, as well as the promotion of public transport.
