20mph pace limits have little impression on street security – examine


utting pace limits on city roads to 20mph doesn’t considerably enhance security, a brand new report suggests.

Researchers analysed knowledge from earlier than and after the restrict was launched on 76 roads in central Belfast in 2016.

The examine discovered “little impression on long-term outcomes” within the metropolis.

Comparisons with streets within the surrounding space and elsewhere in Northern Eire that retained their 30pmh or 40pmh restrict confirmed there have been “no statistically vital variations” when it comes to the variety of crashes, casualty charges or common visitors pace.

Roads with a 20mph restrict did expertise a discount in visitors, in accordance with the report revealed on-line within the Journal of Epidemiology and Group Well being.

The authors of the report, who embrace Professor Ruth Hunter of Queen’s College Belfast and Dr Ruth Jepson of the College of Edinburgh, famous that their analysis was smaller in scale than another research on the subject.

The report mentioned that 20mph limits could possibly be mixed with different measures comparable to driver coaching, CCTV and police communications to “facilitate an formidable tradition change that shifts populations away from the car-dominant paradigm”.

It added that decreasing pace limits is “not merely a road-safety intervention” however may be “a part of the basic reset of the way in which we select our life priorities – folks earlier than automobiles”.

Schemes to chop pace limits to 20mph have grow to be more and more standard within the UK and different elements of Europe lately as a part of effort to cut back crashes and accidents.

The Welsh Authorities has dedicated to decreasing pace limits to 20mph on all roads within the nation the place automobiles combine with pedestrians and cyclists.

RAC street security spokesman Simon Williams mentioned: “The findings of this examine are shocking as they seem to counsel that drivers on 20mph roads in Belfast hardly slowed down in any respect, regardless of the decrease pace restrict, which is at odds with different reviews.

“It appears there’s a major problem with compliance as we might count on that even with out enforcement, common speeds would drop.

“Consequently, the examine could reveal a necessity for councils to seek out different methods to get drivers to decelerate, whether or not that’s by enforcement or modifying street design with visitors islands, well-designed pace humps or chicanes.”

Mary Williams, chief govt of street security charity Brake, described 20mph limits as “life-saving”, significantly for pedestrians and folks driving bicycles and motorbikes.

“The distinction between a 20mph restrict and a 30mph restrict is a doubled stopping distance.”
