Safe construction exits
Safe Construction Exits – Smart Warning Systems for Safer Traffic
Construction site exits where cyclists and heavy vehicles intersect pose a safety risk. At Heidelberg Materials' facility on Johannesfredsvägen in Stockholm, a cycling path runs directly past the exit, meaning that trucks must cross it when leaving the site. To improve safety, a digital warning sign was tested, which automatically activated when a truck was about to exit, alerting cyclists.
The purpose was to evaluate how such a solution could enhance safety and influence cyclist behavior. The tests showed that cyclists became more aware and adjusted their speed, while drivers experienced a greater sense of security when exiting.
The tests focused on:
- How cyclists were affected – did they slow down or stop more often?
- Drivers’ experience – did stress levels decrease, and was awareness improved?
- Technical functionality – how well did the system perform in a real traffic environment?
The results demonstrated that this technology has the potential to improve safety at more construction exits and contribute to a safer urban environment.
