RSS-2-300T Traffic Monitoring Radar

Overview

Targetted at speed enforcement and vehicle counting applications, Geolux RSS-2-300 T is a Doppler radar speed sensor operating in K-band, enhanced with advanced phyTrack vehicle detection and tracking algorithm. Designed for traffic applications, RSS-2-300 T radar sensor reports a list of all currently detected vehicles up to 20 times per second over serial or CAN interface. RSS-2-300 T sensor supports ASCII-S and GLX-NMEA serial interface data protocols, and support for more protocols can be added on customer request.

Field-proven Geolux RSS-2-300 T radar sensor is certified according to both European and American standards, which makes it an ideal solution for our partners that operate globally. Advanced phyTrack vehicle detection and tracking algorithm analyses detected vehicle speeds in real time, and extracts precise target statistics data such as total vehicle count, average speed and road utilisation.

Radar Configurator Software

Geolux provides a user-friendly RSS-2-300 Configurator PC software free of charge. The software connects to the RSS-2-300T radar over serial port and can be used to configure radar operating parameters. Additionally, the Configurator utility displays all currently detected targets, and detected target statistics.

RSS-2-300T stores all detected vehicles’ information to internal memory storage. The capacity of internal memory allows storing data about at least 500,000 detected vehicles. The stored statistics data can be accessed by connecting the RSS-2-300 to the PC using serial cable connection. Geolux RSS-2-300 Configurator PC software downloads the traffic data to the PC and allows its users to export the data to CSV format for further analysis. Geolux RSS-2-300 Configurator also displays traffic statistics information, such as total vehicle count, percentage of speed limit violations, average speed, 85th percentile, 10 km/h pace, speed histogram, time of day histogram, speed limit compliance by hour histogram and speed limit compliance graph.

Speed Limit Enforcement

Detection and precise measurement of over-speed vehicles and objects. The measured vehicle speed is reported over RS-232, RS-485 or CAN data link interface. Additionally, two open-collector alarm outputs can be configured to trigger alarms on various events (overspeed detected, vehicle detected, etc). The radar is able to track up to 32 targets simultaneously, in order as they approach or recede from the radar. The radar can be either permanently mounted on the side of the road or above the road, or it can be temporarily deployed on the tripod during routine police speed-checks.

Advanced Traffic Statistics

Advanced vehicle detection algorithm built in RSS-2-300T enables precise vehicle counting on single-lane roads. For multiple lane roads multiple sensors can be used – one above each lane. The vehicle statistics data can either be stored on the radar Flash memory and retrieved later, or it can be retrieved continuously over radar’s RS-232, RS-485 or CAN data link. The traffic statistics data collected by the radar, such as road occupancy histogram, 85th percentile speed or percentage of over-speeding vehicles can help you to better manage your traffic. Ideal replacement for loop induction sensors, as radar installation does not require road works.

Wrong-Way Detection

According to NTSB’s 2012 report, wrong-way driving is one of the leading causes of fatal accidents on highways. RSS-2-300T radar sensor is preferred, low cost solution, for detecting vehicles driving in wrong direction on highways. The radar can be installed both on slip roads where vehicles enter the highway, and directly on the highway. The radar can interface ITS system or Variable Message Signs through open-collector alarm line that will be active whenever a vehicle driving in the wrong direction is detected.

Smart City Lighting

Energy-efficient smart cities optimise street lighting on streets with low traffic volume by dimming the street lights – or turning them completely off – when there is no traffic present. Many streets with low traffic volume during the night can experience high energy savings, and light pollution is also highly reduced. Geolux RSS-2-300T radar sensor is an ideal traffic-presence detector for such smart city lighting systems. Its long detection range (500 meters) enables the lighting system to gradually dim up the street lights as the vehicle approaches, thus reducing the flash effect on the driver.
