A groundbreaking study conducted by UHasselt, Nuhma, and s-Lim has revealed that the introduction of Average Speed Control on municipal roads in Limburg leads to a significant 38% reduction in traffic accidents compared to similar roads without such controls. 

This comprehensive research carefully isolated the effect of Average Speed Control from other influencing factors — such as improvements in vehicle safety, changes in traffic volumes during the COVID-19 pandemic, and general trends in road safety — by analyzing extensive datasets covering accident locations, road characteristics, and installation timelines of Average Speed Control systems.

At Macq, we are proud that the Average Speed Control systems referenced in this study utilize our advanced ANPR (Automatic Number Plate Recognition) technology, which enables precise and reliable speed monitoring over extended road sections. This technology not only helps reduce speeding but also encourages safer driving behavior and smoother traffic flow

Jan Neyens, director of s-Lim, emphasized the importance of data-driven insights: 

"Our goal is to enable municipalities to weigh the costs and benefits of  Average Speed Control based on solid evidence, helping them make informed decisions about road safety investments."

Professor Wim Marneffe of UHasselt highlighted the key finding: 

"Even when accounting for general safety improvements, Average Speed Control contributes to an additional 38% decrease in accidents, making it a powerful tool for municipalities to improve road safety."

While the study did not find significant changes in the severity of accidents, the clear reduction in accident numbers demonstrates the effectiveness of Average Speed Control in preventing collisions and enhancing safety.
