CIE have estimated the time savings achieved for buses by the introduction of buslanes in Dublin city at 9,500 hours per annum (northside) and 13,300 hours per annum (southside). CIE say that the buslanes have also brought about significant reductions in varifications of bus journey times, thereby facilitating better adherence to schedules.
Surveys carried out show no disbenefit to other traffic.

asked the Minister for Transport the increase in passenger miles that has been achieved by CIE buses since the introduction of bus lanes on the (a) northside and (b) southside of Dublin city.
The bus priority programme began in Dublin in April 1981 and in general the buslanes only operate during peak traffic hours. I am informed by CIE that data on bus usage of the company's Dublin city services is compiled on the basis of passenger journeys rather than passenger miles. Total passenger journeys on Dublin city services in 1980 and 1982 were 175.4 million and 163.5 million respectively. Surveys carried out by CIE of daily passenger journeys in the morning peak in November 1980 and November 1982 were 43,700 and 45,600 respectively, an increase of 4.3 per cent. It is not feasible to provide a breakdown of the foregoing data as between the northside and southside of Dublin.
