FAQs

Q) How do I report a Motorway Incident?

A dedicated motorway incident line has been set-up to assist roads users in difficulty on a motorway. This can be accessed by any mobile phone or landline and all calls are directed through the Motorway Traffic Control Centre by dialling 0818-715-100 (or email operator@nraits.ie).

Q) What is ITS?

The TII also provides a number of services associated with Intelligent Transportation Systems (ITS). The ITS equipment managed and maintained on National roads includes traffic monitoring units (TMU), loop detectors, Automatic Number Plate Recognition systems (ANPR), Closed Circuit Television (CCTV), Variable Message Signs (VMS), Emergency Roadside Telephones (ERT), fibre and wireless communications, power supplies, and associated civil infrastructure. Intelligent Transport Systems are advanced applications which aim to provide innovative services relating to different modes of transport and traffic management. This will enable various road users to be better informed, and make safer, more coordinated and ‘smarter’ use of transport networks.

Q) What is an unusual travel time?

A Travel Time is unusual if the current travel time between an origin and a destination is greater than the typical travel time for that route by a significant amount. The TII's Variable Message Signs aid in managing traffic and keeps drivers better informed across the road network in Ireland. By coupling the TII's journey time technology these VMS are used to display real time travel times across the network.

Q) What is a Variable Message Signs?

Variable Message Signs (VMS) are currently located on various sections of the motorway network in Ireland and aid in:

  • Real Time Journey Information
  • Active Traffic Management of Unplanned Events and Incidents
  • Weather Events
  • Management of Planned Events
  • Road Works
  • Major National Events
  • Safety Campaigns

Q) What is an Emergency Roadside Telephones (ERT)?

There are nearly 1,400 ERT installed on all major routes, which are managed from the Motorway Traffic Control Centre.

An emergency telephone is a phone specifically provided for making calls to emergency services and is most often found in a place of special danger or where it is likely that there will only be a need to make emergency calls. The solar powered phones are located 1.6km apart and are manned 24 hours a days, 365 days a year.

Also a dedicated motorway incident line has been set-up to assist roads users in difficulty on a motorway. This can be accessed by any mobile phone or landline and all calls are directed through the Motorway Traffic Control Centre by dialling 0818-715-100 (or email operator@nraits.ie).

Q) Where does the weather data come from?

The TII operates a Road Weather Information System. This provides local authorities with real time weather data for their area and road weather forecasts to assist them in making informed decisions about salting. Seventy four Road Weather Stations collect local meteorological data. The sensors give continuous data on humidity, air, road surface and sub-surface temperatures and salt concentration on the road surface.

Q) What are Location Reference Indicator (LRI) signs?

Location Reference Indicator (LRI) signs and Location Reference Markings (LRMs) are being deployed along motorway/dual carriageway sections of the national road network to assist road users to accurately communicate where they are. In the event of an incident or breakdown, the road user can relay the information contained on the LRI sign or LRM to describe where a person is located. LRI signs/LRM markings will mean you can, in the event of an incident, inform emergency services exactly where the incident has occurred.

To report a road traffic accident dial 999 or 112

To report debris call the Motorway Traffic Control Centre on 0818 715 100

Q) What information is displayed on a LRI?

All LRI signs contain 3 lines of information that inform the road user of;

  • The road number on which you are travelling
  • The direction of travel, this can only be one of N, S, E or W
  • The distance from the start point of the route
  • LRI signs are located on the nearside verge and are typically spaced every 500 metres although this may be modified at some locations to avoid inappropriate sites.

Q) What are Location Reference Markings (LRMs)?

Location Reference Markers (LRMs) supplement the LRI signs. Location reference Markers are painted in the hard shoulder parallel to the road, every 100 metres. The LRM indicates the route and the direction of travel along with distance from the start of the route. In addition the LRMs indicate the direction to the nearest emergency telephone. An example LRM is indicated in the figure below.

Q) Where can I find LRI signs and LRM markings?

On the road network LRI signs and LRM markings will typically appear on motorway/dual carriageway sections of the national road network, as outlined in this figure. On this site Click here [link to Find a Marker Post] and enter an LRI or LRM label. Alternatively, zoom into the level that LRIs and LRMs are displayed (there are just too many to display all at once when viewing Ireland at a national or provincial level).
