The ‘’20’s Plenty For Us’’ campaign is becoming widely adopted as traffic policy throughout the country. Already more than 5 million people in the UK are living in places where traffic authorities have created safer, more pleasant, quieter streets by introducing the 20mph limit.
The policy relies on 20mph to become the default speed limit backed up by light touch policing. The use of costly and complex traffic calming measures such as humps are unnecessary.
With slower speeds the reduction of danger is obvious: If you are hit by a car at 35 mph your chance of survival is only 50%. If you are hit by a car at 20 mph your chance of survival leaps to 97%.
Reducing traffic speeds on our streets is the single biggest measure which will make them safe, vibrant and social places, not just corridors for traffic. With more pleasant, sociable streets our sense of community grows and people become more likely to walk or cycle than take their car, easing the demand for car parking.
The difference between driving one mile at 20mph and driving one mile at 30mph is only one minute. The health of our children and elderly should not be put at risk for the sake of one minutes faster travel.
20 mph also reduces pollution from exhaust fumes, and is better for the environment and our health.
A few of the benefits of 20 mph include:
• Increasing road safety by reducing the risk and severity of collisions
• Improving accessibility for older people
• Improving the sociability of our streets
• Improving the air quality by reducing emissions from motorised traffic
• Smoothing traffic flow by reducing bunching at junctions
• Reducing noise by lowering the levels of acceleration and deceleration of car engines.
