London plans 20mph speed limit

DIA Insurance ADI News

Londoners are being asked for their views on a reduced speed limit in the capital.
Transport for London (TfL) plans to implement a 20mph speed limit on the roads it operates and manages in central London.
The Transport for London Road Network (the TLRN or London’s ‘red routes’) forms a network of major roads. They make up 5% of London’s roads but carry up to 30% of traffic.
TfL is introducing lower speed limits on roads in two phases:
Phase 1: Roads it operates and manage within central London will have a speed limit of 20mph by 2020Phase 2: Speed limits will be lowered on a further 140 kilometres of the TfL road network in inner and outer London, including on the inner ring road, high-risk roads and roads in town centres. This might mean speed limits will be lowered along some roads from 50mph to 40mph, or from 40mph to 30mph, in addition to introducing areas of 20mph where appropriate
Reasons for the proposed changed include figures from 2016, 2017 and 2018 (provisional), which suggest 128 people were killed in speed-related collisions on London’s streets. A further 2,256 people were reported as seriously injured in collisions where speed was recorded as a contributory factor.
Collision data shows that the faster a vehicle is travelling:
The more likely a collision will occur because the driver has less time to react, stop or avoid the collisionThe more severe an injury resulting from the collision will be
20mph is a safer speed limit than 30mph for roads where space is shared by motor vehicles and people walking, cycling or riding a motorbike. This is because a person walking who is hit by a vehicle travelling at 30mph is up to five times more likely to be killed than if they were hit at 20mph.
