Prevent wrong-way collisions before they happen
The WWD-MX system is a cost-effective, comprehensive, and configurable solution for preventing collisions. Typically installed at or near freeway exit ramps—the primary origin of wrong-way events—WWD-MX is a “smart module” design. It can be configured with LED-enhanced signs or beacons to alert wrong-way drivers and encourage self-correction. Multiple signs can be installed along a ramp to help get drivers’ attention before they enter the main roadway. Adding optional radar to a unit further enhances safety; when the radar unit detects a wrong-way vehicle, the system activates the LEDs to warn the driver of their error while triggering actionable email and text alerts to MX Cloud™. The WWD-MX system monitors highway ramps 24 hours daily for wrong-way vehicles without interfering with other traffic detection systems.
Free out-of-the-box connectivity
WWD-MX systems have connectivity embedded into their design, making installation easy. From the moment a system receives power, it is ‘online’ and accessible both locally via the MX Field App™ and remotely via our web-based software, MX Cloud™.
Timely and actionable alerts
Cities can enable email and text alerts to notify of wrong-way events or other issues like knockdowns or dead batteries.
Comprehensive asset visibility and data collection
System statuses are available at any time in MX Cloud. Users log in to view their systems in a map or list view, bringing together numerous geographically dispersed assets in a single, centralized location. The GPS map provides visibility and enables streamlined, proactive asset management and future planning.
Three reasons to choose an MX Series wrong way detection system:
- MX Field App™ is free forever and provides easy local access to system programs and settings
- Every system includes three years of FREE remote connectivity with MX Cloud™
- Modular design makes for faster installation and better, richer system data

MX Subscriptions
Connectivity isn’t one-size-fits-all. We offer three subscription tiers on all MX Series products, and every system comes with 3 years of standard connectivity for free. With MX Cloud, users can remotely access system locations, alerts, settings and data.

Optional: MX Single Zone Radar Unit
Adding optional radar to a unit further enhances safety; when the radar unit detects a wrong-way vehicle, the system activates the LEDs to warn the driver of their error while triggering actionable email and text alerts to MX Cloud™.
Single Zone Radar
We put solar to work™
Whether your project application is a crosswalk, school zone, or 24-hour sign marking, we can run a comprehensive site assessment to confirm the best solar-powered flashing beacon for your project. We run a field-proven software simulation to create a Solar Power Report™ to show you how we did it. Best of all? It’s free, and we can have it ready in 24 hours.
