What is Speed Management in Connected Work Zones?
Did you know that 30% of fatal work zone crashes are caused by speeding? Also, workers being fatally struck by vehicles while working on foot account for 45% of fatalities recorded at U.S. construction sites. Speed management devices are designed to help lower speeds, and have been shown to lower them by 5 to 7 MPH.
As part of a connected work zone, speed management devices can be programmed to display a lower speed limit when workers are detected on the site or when the work site status is “active”. These devices can also communicate the real-time speed limit to navigation systems such as Waze, allowing drivers be aware of the lower speed limit before reaching the work site.
Applications
Speed Limit Management Systems are mainly used in the following situations:
- Multi-lane highway or interstate work zones without positive protection/clear zones between the motoring public and workers
- Asphalt resurfacing projects and concrete joint repair jobs
- Applications where lanes are intermittently closed for construction
Benefits of Using Work Zone Location Markers
Improved Safety
- Digital speed awareness displays result in an average of 5-7 mph speed reductions
- Speed harmonization for low-speed differentials (slow vs fast) to help reduce rear-end crashes and work zone intrusions
- Speed limit automatically adjusts when work zones are active to help protect workers
Real-Time Information for Stakeholders
- Digital work zone speed limit and Speed Wizard signs provide historical logs of posted regulatory speeds during the project
- Information can be sent to navigation systems such as Waze, and connected vehicles, allowing motorists to be aware of speed limit reductions and slow down in advance
- Information is also pushed through the Work Zone Data Exchange (WZDx) to reach Departments of Transportation (DOTs), Traffic Management Centers (TMCs), and more.
Valuable Data
- Historical traffic data for speed compliance checks and possible targeted enforcement efforts to make cost-effective use of enforcement personnel
- JamLogic provides activation dates, times, GPS location, speed and beacon activation logs
Features
- Part of Ver-Mac’s Connected Work Zone Notification Systems
- High-visibility display
- Autonomous devices (equipped with solar panels and batteries)
