One in 10 Dublin Bus routes failed punctuality target
More than one in 10 bus routes operated by Dublin Bus failed to achieve all their four-weekly punctuality targets over the past two years.
Figures published by the National Transport Authority (NTA) also show that 17 out of 151 "low frequency" routes missed each of 27 targets on punctuality between June 2017 and last June.
They also reveal Dublin Bus missed its general overall target on punctuality for each of six periods during the first half of this year.
It achieved the target in five of 13 periods last year.
NTA figures show the routes that missed every punctuality target since mid-2017 include the 7, 44, 83A and 84.
Buses on most of these routes were behind schedule on just under half of all services.
Among the routes with the worst time-keeping were the 25D (Merrion Square-Adamstown train station).
It missed all 27 targets over the past two years, with an average punctuality rate of 43pc.
On the 41X (UCD Belfield- Knocksedan), services were punctual in only 48pc of cases.
The worst route for lateness was the 33E (Middle Abbey Street-Skerries), with only 36pc of services on time.
Low-frequency services, which account for the majority of routes operated by Dublin Bus, are classed as punctual if they leave from each bus stop along a route not more than one minute early and not more than five minutes and 59 seconds later than the scheduled departure time.
Punctuality targets change depending on the time of year as prevailing traffic conditions have a significant impact on performance.
A spokeswoman for Dublin Bus acknowledged that some routes had exceeded targets for punctuality in the first half of this year while others were below target.
"Dublin Bus always strives to continuously improve and provide our customers with the best service possible," she added.
While Dublin Bus could control some aspects of punctuality, she said, its services were subject to a "variable traffic envir- onment" which was outside the company's control.
