Changes to access roads onto Dublin's M50, new signage to direct motorists to alternative routes in the event of lane closures caused by collisions, and new orbital bus routes will be used to reduce gridlock and reduce the risk of collisions.

The main measure involves introducing so-called variable speed limits, where the upper limit is reduced at peak times.

This helps maintain average speeds across the length of the motorway, with less crossing and risk of collisions.

It comes amid growing concern about rising traffic volumes on the motorway, which caters for in excess of 350,000 vehicles a day.

Economic growth has resulted in heavy congestion at key junctions, with volumes up 7pc so far this year.

Transport Minister Paschal Donohoe has announced a number of new measures, including improved merging layouts, currently being trialled on the N3 and M1 airport junctions.
