Why do we need sensors at all? 

Vehicle Counts



Road Maintenance & Speed Monitoring



Congestion Evaluation – New Route Creation – Maintenance Costs



Volume, Speed, Occupancy, Vehicle Classification, Headway

In-Roadway In Roadway Sensor Technology gy 

Imbedded in the Pavement

Magnetic Sensors 

Changes in magnetic field trigger counts



Vehicle counts, speed, classification



Less susceptible than loops to traffic & temp – Insensitive to weather such as snow rain & fog snow,



Installation requires pavement cuts or boring under roadway – can not detect stopped vehicles – Requires lane closures for installation

GroundHog

Inductive Loop Detectors 

Changing loop inductance sends signal to traffic controller



Most Common Sensor used in traffic management



Mature well understood Technology – large experience base – provides basic traffic parameters



Installation requires pavement cuts – Improper installation decreases pavement life f – Installation and maintenance requires lane closures – Wire loops subject to stresses of traffic and temperature – Multiple loops usually required to monitor a specific location

On-Roadway Sensor Technology: 

Taped p to the Pavement



Temporary Applications

Pneumatic Road Tube

Pneumatic Road Tube 

Bursts of air pressure close air switch to count traffic traffic.



Temporary Traffic Counting



Quick installation for temporary counts



Inaccurate Axel Counts – Temperature Sensitivity – Vandalism – Truck Tire Wear – Traffic Control Needed

Temporary Traffic Analyzer

NC200

Over-Roadway Sensor Technology 

Above the Roadway – OR –



Alongside the Roadway

Video Image Processor

Infrared Sensors 

IInfrared f d energy reflected fl d from f vehicles hi l iis ffocused d on an optical sensing system



For Presence Detection – Volume - Speed Measurements – Classification



Does not require in-pavement installation – accurate measurement of vehicle p position speed p and classification



Relatively short operating range – Performance degraded by inclement weather or direct sunlight

Ultrasonic Sensors   



Transmit pressure waves off sound above Human auditable range Presence Detection - Speed Calculations – Doppler Affect Does not require in-pavement installation – Accurate measurement of vehicle position speed and classification Temperature change and air turbulence degrade performance

Microwave Radar

Why Radar does a Great Job Job.       

Non Intrusive: out of roadway Installation safety Zero set back Not affected by y weather Solar power option Gathers all variety of data Bluetooth data download

RTMS G4 K-Band K Band Radar

Value For Lean Times

Go cabinet free Bluetooth communication option. i

Compare the costs… All-in-one…no add-on costs Solar or AC Zero Set Back No Cabinet Training Data Collection

Solar Power Where There’s No AC

RTMS slashes power costs by 3 - Only 3 watts - Smaller Solar Panels - Cloudy Days No Problem!

RTMS covers both sides of the highway with one unit – others make you buy two. Two extra lanes of coverage per sensor enable future growth without future cost: That’s value!
