Motorways in Ireland have experienced growth in demand over the last few decades due to a rise in vehicular traffic, impacting greatly on the operational capacity of the various high mobility conduits during peak hours. This is especially the case in Cork city on the N40, M8, N8 and N25 motorways on their approach to the Jack Lynch Tunnel and Dunkettle Interchange. Whilst this increased activity may be indicative of economic growth, the recurring congestion resulting from this reduces the mobility of road users at peak hours and is likely to impact the environment negatively through increased greenhouse gas (GHG) emissions. The increased vehicular activity is also highly likely to have adverse implications on road safety across the highly trafficked sections of motorway in and around Cork city. To manage the demand and remedy the impacts thereof, there is active deployment of various Intelligent Transport Systems (ITS), in line with Transport Infrastructure Ireland (TII)’s vision “to ensure that Ireland’s national road and light rail infrastructure is safe and resilient, delivering better accessibility and sustainable mobility for people and goods”. This paper seeks to highlight the pragmatic approach selected, including the key considerations and the challenges encountered in the development of the concept and design of the EU-funded MERIDIAN Cork Co-operative Intelligent Transport System (C-ITS) on behalf of TII.
