Bus Éireann announced last night it is renumbering all city routes with immediate effect to facilitate the rollout of real-time passenger information displays.
The electronic signs at bus stops will use GPS to show passengers where the next bus is.
A Bus Éireann spokesman said the names of the city routes will move to a standard three-digit format, but stressed that there would be no impact to service frequency or route.
The route numbers will change as follows:
*Route 1 will become route 201.
* Route 2 becomes route 202.
* Route 3 is now route 203.
* Route 5 is route 205.
* Route 6 is route 206.
* Route 7 is route 207.
* Route 8 is route 208.
* Route 9 is route 209.
* Route 10 is route 210.
* Route 11 is route 211.
* Route 12 is route 212.
* Route 14 is route 214.
* Route 16 is route 216.
* Route 19 is route 219.
The changes have been sanctioned by the National Transport Authority.
Testing began earlier this month on the new electronic display signs in the city.
The first of the 47 real-time bus display units was installed at the bus shelter opposite the Washington St courthouse.
The signs will show precisely how long passengers will have to wait for the next four buses by using GPS to track the location of the buses.
There are also plans to link the system to traffic-light management systems to give buses priority.
Eight signs will be installed at the various stops on St Patrick’s Street, four units at bus stops on Grand Parade, three on the South Mall, two at Victoria Cross, two on College Road, two on Merchants Quay, and three units in Ballincollig.
Individual display units will also be located at Kent Station, CIT, CUH, St Luke’s Cross, MacCurtain Street, Dillon’s Cross, IDA Park on the Model Farm Road, Wilton Shopping Centre, Cork Airport, the Black Ash Park & Ride, Lavitt’s Quay, Lancaster Quay, Dennehy’s Cross, Barry’s Pub in Douglas and outside Scoil an Spioraid Naoimh in Bishopstown.
