What types of sensors are used in transportation?
Roadway Sensors
- Inductive Loop Detectors (ILD) Inductive loop detectors are currently the most widely used devices for vehicle detection, although microwave radar detection is also common.
- Microwave Radar Detectors.
- Infrared Sensors.
- Ultrasonic Detectors.
- Acoustic Detectors.
- Magnetometers.
How does a vehicle sensor work?
Using echo-times from sound waves that bounce off nearby objects, the sensors can identify how far away the vehicle is from said object, and alert the driver the closer the vehicle gets. Electromagnetic sensors create an electromagnetic field around the bumper, and offer an alert whenever objects enter it.
What are traffic sensors?
What are Traffic Sensors? At a basic level, sensors in traffic control systems are used to detect the presence of vehicles at specific points. Sensors can be used to measure and monitor the number of vehicles that pass through a specific point, the speed at which the vehicles are traveling, and more.
How are pressure sensors used in traffic control systems?
Pneumatic road tube sensors use one or several tubes placed across traffic lanes allowing for number of vehicles counting and vehicle’s classification. When a vehicle’s tire passes over the tube, the sensor sends a burst of air pressure which produces an electrical signal.
How are sensors used in the transportation industry?
Various traditional and newly-developed sensors have been used in various aspects of transportation systems for accurate information acquisition, effective monitoring, and optimal decision making.
What kind of cargo sensor do I Need?
Used with the ORBCOMM® AG 400, ST 9100 or GT 1200 series, the sensor provides both general cargo area temperature and multi-zone monitoring in refrigerated trailers and trucks independent of the refrigeration unit.
How long does it take to install a cargo sensor?
Ideally suited for large-scale deployments, the GT 1200 series can be installed in about 10 minutes to minimize operational disruption. Use on any trailer or container asset type and in any orientation.
How does a door sensor work on a trailer?
Door Sensors. ORBCOMM’s wireless door sensor delivers enhanced visibility of trailer and container operations and improved cargo security. The DS 300 detects when doors open or close, enabling fleet operators to know if the cargo area is being accessed as scheduled and react quickly to unexpected openings.
