Inductive Loop Detectors Changing loop inductance sends signal to Traffic Controller 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

fDecreases Pavement Life –Installation and Maintenance requires Lane Closures Wirerequires Lane Closures – Wire Loops Subject to stresses of Traffic and Temperature –Traffic and Temperature Multiple Loops usually required to monitor a specific location

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

Installation requires pavement cuts Installation requires pavement cuts or boring under roadway – can not detect stopped vehicles – Requires Lane Closures for Installation

Get what you need to get the job done – at the lowest costs.

All-in-one…no add-on costsOthers require costly add-ons. With RTMS, it’s all built-in. You don’t need cabinet training to get RTMS field-installation. RTMS plug-and-plan concept saves money today and down the road.

RTMS slashes power costs by 3Get triple the power savings with RTMS! Only a small solar package is required – versus thea small solar package is required versus the hefty package that others demand.

The value of 12 lanes versus maximum of 10 lanesRTMS 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!

We know budgets keep shrinking – we understand your world. RTMS offers a real-life, practical, value-based solution versus academic blueprint thinking.

Tip the scales in your favorGet the confidence of knowing you’re dealing with an established public company that’s been in business around the world for two decades. A company and product you can count on.

RTMS can be installed on existing poles wherever they are located – even right up to the curb. Others need an entire lane of setback, which means costly new poles on arterial roads, bridges, ramps and flyovers.

RTMS AdvantagesCheck the facts – see for yourself.
