Traffic in the United States has increased 30 percent in the past ten years, and the number of cars on the road is projected to increase by 50% in the next decade. As vehicular traffic increases, it has become increasingly difficult to collect traffic data accurately in congestion using traditional sensors such as piezos, road-tube or standard inductive loops. As freeways and urban areas become more congested, data quality deteriorates. Traditional sensors do not count accurately at low speeds, with bumper-to-bumper or with stop-and-go traffic.

Traditional Inductive Loop technology can "join" vehicles, resulting in under counts. Piezos and road tube sensors miss axles or miscalculate spacing at low or irregular speeds resulting in inaccurate vehicle classification. States have not been able to provide accurate data to the FHWA from major arterials and urban freeways, especially at peak times because traditional sensors are unable to
cope with recurring congestion due to sensor saturation.

Peek Traffic responded to this critical problem by combining 40 years of expertise in both data collection and inductive loops with advanced inductive loop detection algorithms (using Idris Technology^® and Idris^® Smart Loops^*).

How Does it Work?

The ADR-6000 is a modular single or multilane data collection system that offers accurate vehicle count and axle based classification in traffic conditions ranging from free flow to stop-and-go congestion. The system can be set up and operated by remote telemetry or directly in the field with a computer using simple communications software. The remote telemetry link can be via modem, direct connection, or 10/100 Base-T Ethernet.

Data Collection Tools

The ATC-6000 generates a great deal of useful data, requiring tools to retrieve and manage this data. Fortunately, the ATC-6000 is completely compatible with Peek's two ADR data management software packages: the TOPS data management and reporting tool, and the IQ Data advanced data processing package.
