Wrong Way Detection
Opsys’ proprietary LiDAR technology provides real-time reliable detection of wrong-way driving. Opsys’ LiDAR solution, the ALTOS, provides instant signaling to alert the driver as well as oncoming traffic to save lives. LiDAR enables detection in all weather conditions, including at night, where cameras often fail.
The ALTOS creates a real-time 4D image of the vehicle and the road and uses this info to provide the wrong-way warnings, unlike traditional wrong-way systems. By using an optional ethernet relay with analog outputs, the system can be used to trigger, for example, a warning sign directly. The ALTOS can also be integrated into D/IO or NTCIP as well as more complex traffic management systems using protocols like NTCIP.
Features & Benefits
High-Accuracy Detection for Critical Events
-
Precise, real-time vehicle detection and tracking minimizes false positives and ensures rapid identification of wrong-way vehicles
-
Point-by-point scanning improves signal-to-noise ratio and enhances detection accuracy per vehicle, even in high-speed or complex environments
Environmental Reliability & Ruggedness
-
Performs in all weather and lighting conditions: Infrared-based sensing ensures consistent operation day or night, including fog, rain, or glare—no need for external illumination
-
Rugged, solid-state design: No moving parts means high durability and continuous performance in harsh roadside environments (e.g., tunnels, bridges, highway medians)
-
Proven long-term reliability: Engineered for extended service life with minimal degradation in performance (no mechanical failure points)
Deployment Efficiency & Power Flexibility
-
Low power consumption: Suitable for solar or battery-powered installations, ideal for remote or infrastructure-limited locations.
-
Compact all-in-one unit with Power over Ethernet (PoE): Streamlines installation and reduces cabling complexity.
-
Minimal maintenance requirements: Designed for unattended operation with long mean time between failures (MTBF).
Scalable & Smart-Infrastructure Ready
-
Edge processing: Enables instant, on-device decision-making for immediate threat response and alerting.
-
Seamless integration with ITS systems: Can trigger signage, VMS boards, lighting, or automated alerts for real-time driver warnings.
-
Flexible deployment: Easily scaled across multiple sites and infrastructure assets to ensure full roadway coverage.
ALTOS 150 for Wrong Way Detection
This point cloud video shows Opsys’ demo software monitoring traffic on a regular two-lane road. The ALTOS detects wrong way by analyzing the vehicle’s driving direction. The Opsys’ demo software, Opsight, visualises when a car is driving in the wrong direction, and at the same time, can measure vehicle speed.
In this recording the ALTOS 150 unit is used with its maximum range of 150m and a FoV of 45° x 13°. The fully integrated solution is a perfect fit for different traffic monitoring application thanks to its simple installation and low cost due to the integrated perception stack.
