Some 1,949 speeders were detected on Northern Ireland Road Safety Partnership cameras along the length of the A1 locally last year.
The highest number recorded at NIRSP mobile camera sites across Northern Ireland in 2015, the total, for the A1 Sprucefield roundabout to Sheepbridge Road, near Newry, stands at more than three times 2014’s figure of 604.
The same stretch of road is also one of four where individual drivers were detected travelling at 99mph, the highest speed recorded in 2015.
Meanwhile, on Carryduff’s Ballynahinch Road, the partnership’s mobile cameras detected 623 speeders, up from 462 in 2014.
Elsewhere in the wider Lisburn and Castlereagh area detections were minimal.
Staying in Carryduff, detections on the Saintfield Road fell from 10 in 2014 to eight last year, while on the A7 Saintfield Road/Belfast Road one speeder was detected.
There was one detection on Lisburn’s Knockmore Road and none at all on the Prince William Road.
The figures are included in a 2015 statistical report from NIRSP, which currently operates eight safety camera vehicles across 90 permanently signed locations, as well as four fixed safety cameras, six fixed red light running cameras and one average speed enforcement camera system.
Provincewide, the partnership detected 46,500 people (about 127 a day) either speeding or running a red light, an increase of 9.6% on 2014’s total, though the 3,639 deployments of NIRSP vans in 2015 was itself a 12.1%increase on the number of deployments in 2014.
Of those detected speeding last year, 23,970 (51.5%) resulted in the driver attending a speed awareness course; a further 20,870 (44.9%) were referred for a fixed penalty notice while the remaining 1,660 (3.6%) were referred to the Public Prosecution Service.
May was the month with the highest number of detections (4,904), while December had the lowest (2,644).
On the A1 Sprucefield to Sheepbridge Road, July saw the highest number of detections (266), February the lowest (66), while at Ballynahinch Road, Carryduff, detections peaked at 119 in May and, save for December, when there were no detections, otherwise fell to their lowest (19) in April.
Where age was known, over one third of those detected provincewide in 2015 were aged 40 – 54 (34.4%); some 32.2% were aged 25 – 39 and under 25s accounted for 10.4%.
