Research finds average speed reduction from 20mph limit is only 1.3mph
A new study has found that the average speed reduction from 20mph speed limits is only 1.3mph and as a result 20mph speed limits, which have been introduced up and down the country, could possibly make some roads more dangerous.
A review of specific areas which have introduced the 20mph zones was carried out by Bath and North East Somerset Council, who discovered the rate of people seriously injured or killed had risen in seven out of the thirteen areas looked at.
According to the study, there’s “no simple explanation” as to why the number of casualties increased in some areas but suggested that it could be down to the fact that people assume the area is much safer because of the 20mph restrictions and as a result are less attentive when crossing the roads, walking, cycling or simply travelling along the road.
An experimental control was set up which didn’t have a 20mph restriction and the results also showed an increase in the rate of road users being seriously injured or killed, however, only three out of the thirteen areas noticed a reduction in rates of people being killed or seriously injured once a 20mph zone was introduced.
Each of the four rural areas being studied noticed a greater number of casualties within a 12 month period.
As researchers discovered the average speed reduction from 20mph limits was just 1.3mph, they concluded that there’s no real persuasive argument for carrying on with the 20mph programme going forward.
A total of 1,499 roads within Bath and North East Somerset Council’s area have had 20mph speed limits put in place over the past six years, costing £871,000.
The zones would cost just as much to be removed so for now will be staying put as the council says they haven’t got the money needed to remove the 20mph zones.
