The non-intrusive, radar-based RTMS Sx-300 is an advanced sensor for the detection and measurement of traffic on roadways. It is all-weather accurate and virtually maintenance- free. Best of all, Sx-300 is renowned for long-term worry-free reliability.
The RTMS Sx-300 is a small roadside pole-mounted radar, operating in the microwave band. Simultaneously, the sensor provides per- lane presence as well as volume, occupancy, speed and classification information in up to 12 user-defined detection zones. Output information is provided to existing controllers via contact closure and to other computing systems by serial or TCP/IP communication port. A single radar can replace multiple inductive loop detectors.

GENERAL FEATURES

• Provides presence indication and accurate measurements of volume, occupancy, speed and classification in up to 12 separate zones (lanes) up to 76 meters (250 feet) away
• Fully programmable to support multiple applications using simple intuitive software on a Notebook PC
• True-presence: detects stationary and fast moving vehicles; single or dual loop emulation
• Reliable all-weather performance
• Low life-cycle cost with no routine maintenance procedures and high reliability.
• Typical MTBF – 10 years or 90,000 hours
• Easy to calibrate by fast, automatic set-up wizard
• Fast, safe installation, on existing road-side poles, with no traffic disruptions
• Compatible with all RTMS integrated solutions including detection station, counting, urban traffic control, event reporting, data collection.
• Highly fl exible: suitable for any road and pole type, with various built-in communication options, including contact pairs and TCP/IP.
• Zero Setback feature means any pole is suitable
• Low power requirement allows low cost solar power operation

APPLICATIONS

• Mid-block detection for intersections (advance detection)
• Freeway traffic management and incident detection
• Traveler information and journey time prediction
• Ramp metering
• Queue detection
• Work zone safety systems
• Permanent and mobile traffic counting stations
• Loop replacement (single or dual loop emulation)
