Roughan & O’Donovan-AECOM has been engaged by Transport Infrastructure Ireland (TII) to deliver consultancy services for the enhancing Motorway Operation Services (eMOS) programme.

The eMOS programme will enable TII to:

  • react to real-time events on the network
  • display lower speeds on new digital signs installed on overhead gantries in response to conditions on the motorway
  • enhance protections for emergency responders dealing with incidents on the M50
  • keep road users better informed about incidents ahead and how they may affect their journey

Digital signs were first introduced on the M50 in October 2021, starting at Junction 4 Ballymun. The roll out continued in 2022 and 2023, and digital signs currently extend from Junction 4 Ballymun to Junction 12 Firhouse.   

The programme is being rolled out in a phased manner to give road users time to familiarise themselves with the new signs and adjust their driving behaviour accordingly before the introduction of regulatory speed limits.

Programme objectives

The eMOS programme is designed to protect the M50 by:

  • safeguarding the safety, resilience and sustainability of the motorway network
  • reducing the adverse impact of future traffic growth on service levels on this key strategic link
  • providing TII with the systems to deliver a more efficient, flexible and responsive service to road users


Roughan & O'Donovan-AECOM will provide the full suite of expert services required for the deployment of intelligent transportation systems (ITS) equipment on the M50 motorway.

The programme consists of three key strands:

1. The expansion of the existing Dublin Tunnel Control Building to provide a new, state of-the-art motorway operations control centre that both modernises and futureproofs the environment in which TII manages the motorway network

2. The deployment of intelligent transportation systems (ITS) technology and equipment on the M50, including lane control signals, variable message signs (VMS) and CCTV coverage

3. The implementation of an overarching, adaptive system that receives and processes information from multiple roadside traffic monitoring devices, allowing operators to set signs on the M50 and provide a more integrated road management service to road users

Services to be provided:

  • Engineering consultancy
  • Environmental engineering consultancy
  • Site supervision
  • Contract administration
  • Project Supervisor Design Process (PSDP)
  • Public communications, including video and audio production
