The real time system for Dublin Bus is to be replaced in the next two to three years, its CEO has confirmed.
The National Transport Authority (NTA) has awarded a contract to a vendor for the replacement of the system.
It has come in for criticism around no-show or so-called 'ghost buses' that don't show up.
Dublin Bus carries more people every day than any other public or private transport provider in Ireland, with over 145 million passengers carried last year.
Dublin Bus CEO Billy Hann told Breakfast Business the issue of 'ghost buses' is down to older technology.
"As a user of Dublin Bus myself this is something that happens from time to time and frustrates me," he said.
"Unfortunately, the problem is mainly down to the age of the technology.
"The technology is over 15 years old [and] the antennas on the buses aren't as sensitive as they need to be.
"The good news is that the National Transport Authority, who actually own the buses, they've just awarded a contract to a vendor for the replacement of that system.
"That will be implemented over the next two to three years which will improve the reliability of the RTPI (Real-Time Passenger Information) system".
Mr Hann said real time system is "independently audited by the National Transport Authority" with an accuracy rate of around 96%.

"We have 1,100 buses in our fleet - approximately 70% of them are diesel, 20% are [hybrids] and now we're starting to get into the electric vehicles," he said.
"We've approximately 10% of them within our fleet at the moment.
"Ultimately by 2035 the idea is to [have] zero tailpipe emissions with regards to our vehicles".
Mr Hann said problems last year, which prevented electric buses from being used due to a lack of EV chargers, have been resolved.
"This is a fairly new project for Dublin Bus and for the city of Dublin, there's complexities with it," he said.
"There was planning complexities at that particular time - we have all these chargers installed now, certainly at our Phibsboro and Summerhill depots.
"They're the first two depots to be electrified.
"They're in place now and we're running electric vehicles from those two depots at this moment in time".
Mr Hann added that contactless payments allowing people to pay by card or with their phone will also be operating "within the next two to three years" on Dublin Bus.
