Laser Detectors

Unlike radar, which measures speed and presence via radio waves, or video, which relies on visual image processing, lidar uses laser pulses to generate a precise 3D point cloud of the roadway. This provides more accurate object classification and distance measurement, and performs reliably in poor lighting, glare, and adverse weather where cameras may struggle.

Modern solid-state lidar detectors like the Ouster Lidar are designed to function reliably in rain, snow, fog, glare, and nighttime conditions. This all-weather performance makes them well-suited for continuous traffic monitoring and signal actuation in regions with variable climates, such as the Midwest.

Yes, many laser detection systems are engineered for seamless integration with modern traffic controllers. For example, the Ouster Lidar and BlueCity platform connects directly with Econolite Cobalt ATC controllers and EOS firmware, enabling dynamic signal actuation and adaptive control based on real-time detection data.

Laser detectors are typically mounted non-invasively above or alongside the roadway, eliminating the need for pavement cuts or lane closures required by inductive loop systems. This reduces installation time, labor costs, and traffic disruption compared to traditional detection methods.

Solid-state laser detectors have no moving parts, which significantly reduces maintenance needs compared to mechanical or loop-based systems. Routine checks typically involve verifying sensor alignment, cleaning lenses, and confirming software or firmware updates to maintain optimal detection accuracy.

Laser detectors can capture detailed data on vehicle counts, classifications, speeds, pedestrian and cyclist movements, and near-miss conflict events. This data supports Smart City analytics, Vision Zero safety initiatives, and long-term transportation planning through cloud-enabled reporting platforms.
