Compared with Doppler Radar

Individual vehicle speeds and traffic volume data
Vehicle classification by length
Roadway occupancy measurements
More detailed, lane-specific traffic information
Monitoring of up to 16 lanes
Bidirectional monitoring, including traffic traveling in opposite directions

A multi-lane microwave radar, commonly referred to as side-fire radar, designed to collect detailed traffic data across multiple lanes and directions simultaneously.

Microwave radar is particularly valuable in more sophisticated SmartZone deployments where traffic volume, occupancy, classification, or lane-specific information is needed in addition to vehicle speeds. It can also operate independently of SmartZone as a dedicated traffic data collection system.

Other sensor manufacturers and models can be accommodated upon request.

SolarTech provides integrated sensing and traffic management solutions, not just individual sensors. Depending on your needs, we can integrate sensors into existing SolarTech equipment or provide a dedicated solar-powered trailer with the necessary communications, power supply, and mounting hardware. Use them for basic traffic data collection and monitoring, for remote surveillance, or integrated with SmartZone to automate traffic safety equipment based on changing roadway conditions.

What makes our ITS sensors different?

Complete Solutions, Not Just Sensors

SolarTech provides integrated sensing and traffic management solutions, not just the individual sensors.

On Your Equipment or On Its Own Trailer

We can integrate sensors into existing SolarTech equipment or provide a dedicated solar-powered trailer with the necessary communications, power supply, and mounting hardware.

Standalone or Part of SmartZone

Use them for basic traffic data collection and monitoring or remote surveillance, or integrate them with SmartZone to automate traffic safety equipment based on changing roadway conditions.
