Abley was approached recently to comment on the results of a Christchurch Transport Operations Centre (CTOC) survey of 15 city intersections, which found red lights were ignored 8170 times in just 24 hours, or 340 times per hour.
The Canterbury Region: Road Safety Report 2013-2017 written by Abley in early 2018, confirmed red-light running was "prevalent".
The report found half (52 per cent) of injury crashes in Christchurch were at intersections, far above the national average of 37 per cent.
Both right turning against traffic crashes and intersection crashes were proportionally over-represented in Christchurch compared to the national average.
Steve Abley explains "Christchurch's grid-based design meant it has a large number of right-angled intersections. If they all had right-turn arrows, congestion would go up dramatically and so too would red-light running as drivers became frustrated. Safety could be improved by reducing speed limits and limiting turn movements."
