Impact of speed bumps and speed humps on road safety

Numerous studies conducted across the United Kingdom have consistently demonstrated the positive impact of speed bumps and speed humps on road safety, particularly in areas with high pedestrian and cyclist activity.

One comprehensive study undertaken in a school zone found that the installation of speed bumps resulted in a remarkable 50% reduction in pedestrian-related accidents and injuries. The findings clearly illustrate the effectiveness of these traffic-calming measures in protecting the most vulnerable road users, who are often children and young people.

Similarly, in a residential neighbourhood setting, another study revealed that the introduction of speed humps led to a 30% decline in the number of serious accidents. This significant improvement in safety outcomes can be directly attributed to the ability of speed humps to compel drivers to slow down and navigate the raised obstacles with greater care and attention.

Beyond their impact on accident and injury rates, speed bumps and speed humps have also been shown to have a positive effect on noise pollution levels. Research has indicated that the installation of speed bumps can reduce noise levels by up to 10 decibels, contributing to a more peaceful and liveable environment for local residents.

The proven track record of speed bumps and speed humps in enhancing road safety and mitigating noise pollution underscores their invaluable role in creating safer, more pedestrian-friendly communities across the United Kingdom. As local authorities continue to prioritise the needs of vulnerable road users and strive to foster a culture of responsible driving, these traffic-calming measures will undoubtedly remain an essential component of the country’s road safety strategy.
