Towards a European Guideline for Speed Management Measures in Work Zones

Speed management in work zones is important to ensure that the driver safely can navigate the vehicle through the work zone routing. The ASAP project, Appropriate Speed saves All People, was designed to address this issue, with its specific focus on speed management measures and treatments that increase road safety both for the road workers and the road users. The objective was to provide a best practice document that can be applied across Europe with recommendations on how to effectively manage speed through roadwork zones. The guideline provides solutions to help achieving the appropriate speed on different road types and roadworks independently of country. The study showed that most of the speed management measures have some effects on reducing speeds, and even when only minor speed reductions are achieved, these measures may effectively alert drivers to an upcoming roadwork, thereby increasing the safety.
