Automatic Data Recorder

Data Collection

The Peek ADR-3000 Plus provides optimal functionality as a permanent site unit. With the various options the ADR-3000 Plus can count up to 64, or classify up to 32 lanes of traffic, including up to 24 WIM sensor inputs.

Several exclusive features have been incorporated into the ADR-3000 Plus. The CPU electronics are fitted with a replaceable socket mounted fuse, protecting against an accidental power reversal, and subsequent damage. Front panel mounted LED’s indicate a successful start up of the microprocessor by blinking twice during the boot cycle. LEDs also worn of system fault conditions and indicate the communications port activity and status. Additionally, a reset switch that is mounted on the front panel of the ADR-3000 Plus can be used to re-start the CPU. This provides an easy method of restarting a unit during diagnostics, similar to cycling power.

Each unit can perform up to eight studies, plus generate per-vehicle records, with up to 356 bins of data. This could include, for example, classification by speed, by lane, and volume. The type, configuration, and format of data to be collected can be custom programmed or selected from menu-driven choices. Available data types include per-vehicle records, per-lane data, binned vehicle classification by axle, speed, length, gap, or headway, or almost any combination of these classifications. Vehicles can also be classified according to either a Scheme “F” or a user-defined classification scheme.

Quality Assurance

Each unit is individually tested for correct operation during a computer controlled environmental chamber test cycle, based on the NEMA T5/2 standards. All input circuits have been designed and tested to the NEMA T5/2 standards for surge (lightning) protection.

Optional Features

The Peek ADR-3000 Plus is a modular multilane vehicular traffic counter/classifier that can be set up and operated either remotely via telemetry or directly in the field via a computer with appropriate software. The optional front panel mounted keypad and display provides autonomous local control. Setup and operational performance of the Peek ADR- 3000 Plus is enhanced for simple and reliable field traffic data collection. Easy to use menus allow configuration flexibility. Optional setup files are available which help reduce confusion and operator errors. Collected data is held onboard, secure from unintentional erasure or loss.

Physical Description

The Peek ADR-3000 Plus is an instrument rack-based unit, expandable by function with individual plug-in modules. Available to fit standard EIA 19″ or Type 170 enclosures, the Peek ADR-3000 Plus may also be shelf or panel mounted. Electrical connections (external) are via rear mounted terminal strips for sensor inputs. Communications are supported via an RS232-C DB-9 connector. Plug-in modules can consist of power supply, central processing unit, communications, control panel, memory, loop sensors, piezo sensors, weigh-in-motion sensors, contact closure inputs, analog to digital inputs or a combination of these for a particular application. Individual plug-in modules are Eurocard in size with DIN standard connectors. Typical module width is 1 inch.

Power options include 115 VAC, 6 or 12 VDC, solar power and operational battery-backup as necessary. An internally supported hardware real time clock maintains time and date, regardless of unit power, for up to ten years.

Support Software

Of importance to the user of modern counters/classifiers is the operating and reporting software, which supports, controls and formats the resultant data. A user-friendly Windows(TM) software package is available to complement the Peek ADR-3000 Plus. This software is the Traffic Operations Processing Software (TOPS) program, which is available from Peek Traffic.

The TOPS program provides multi-file processing, stores data files into a single database for easy file sharing among TOPS users, allows for edit and preview of reports before printing, provides for ADR data processing protocols, enables remote or local setup of Peek ADR units and collection of data by direct manual connection or by the added functionality of automatic telemetry polling of field sites via modem connection (auto polling and weigh-in-motion support are add-in options). The TOPS program reads all files and generates a suite of daily, weekly and monthly reports. A user definable classification function, within the program, provides the ability to customize classification and to transfer the new scheme to the Peek ADR-3000 Plus. Processed data may be exported to various other software packages.

Two Year Limited Warranty
