Dublin's M50 is set to become a "dynamic motorway", with variable speed limits determined by computer algorithms.

There will also be the ability to close individual lanes and junctions using "Red X" signals on almost 100 overhead gantries.

The system will be able to close lanes and reduce traffic speeds in the event of a crash or severe weather events, and one of its key aims will be to get more vehicles along the motorway per hour, particularly at congested times, while ensuring safety.

To find out more about the plan, we were joined by Sean O'Neill, Director of Communications at Transport Infrastructure Ireland.
