RFP 34366 – Weigh-In-Motion Equipment Att H

ATTACHMENT H – MANDATORY TECHNICAL SPECIFICATIONS

These Specifications describe the requirements for Weigh-In-Motion equipment including controllers, sensors, cameras, Green Light communication, and weigh station components. The devices must integrate into a complete system and perform all functions described within these Specifications. Installation and maintenance of these materials, as well as existing Weigh-In-Motion equipment, will be completed by authorized ODOT personnel.

The list of parts and equipment included in the Price Agreement is not intended to be all-inclusive. Rather, it highlights the most commonly used items. There may be additional items necessary to the overall operation of the system that are not included in the Mandatory Technical Specifications.

All Goods used shall be new, unused, and produced from manufacturers’ current production components. ODOT will have the option to supply materials to be used on a project if it is in the best interest of ODOT.

In addition to materials, the Contractor shall provide on-site support for the configuration of the systems for new installations and for repair/maintenance support pricing on Price Proposal Form. Calibration and testing of all supplied sensors will also be required as part of on-site support. On-site support will be requested by the Agency with a minimum 2 week lead time. Contractor shall provide current calibration and testing documentation that explains how to configure, calibrate, verify measurement, and maintain WIM systems and components for any sites or systems contracted for services.

The Contractor shall also provide training pricing on the Price Proposal Form. Contractor shall provide documentation on how to configure, calibrate, verify measurement, and maintain all WIM systems and components provided as part of training.

The Contractor shall provide telephone support during standard business days (Monday through Friday) and standard operating hours (8:00am to 4:00pm PST).

Note: These specifications are subject to change based upon the final specifications negotiated with the awarded Contractor, any desired/optional items awarded will be inserted prior to award.

SECTION 1: Requirements of the WIM System

1.1 Mainline and Ramp WIM System: The Mainline and Ramp Weigh-In-Motion Systems must be capable of collecting, storing, and communicating to the Agency’s central collection system the following data from physically connected or network connected sensors and cameras simultaneously. The mainline WIM system shall be capable of collecting data from vehicles travelling at freeway speeds up to 65 MPH.

· Vehicle weight

· Vehicle length or classification

· Vehicle speed

· Axle count

· Axle spacing

· Axle weight

· Over-height vehicle indication

· Commercial vehicle license plate camera image

· Commercial vehicle license plate optical character recognition text

· Commercial vehicle side camera image

· Tire safety screening

· Vehicle transponder identification via 915 MHz signal (Mainline WIM System only)

The Mainline WIM System shall be capable of transmitting in the 915 MHz unlicensed spread spectrum band. The WIM system shall be capable of sending a radio signal to commercial vehicle Green Light transponders to “bypass weigh station” or “report to weigh station” based on the measurements taken by the system and thresholds set by ODOT. The signal output shall be capable of interfacing with Green Light transponders from the following manufacturers:

· Kapsch

· PrePass

· NORPASS

· BESTPASS

The Mainline and Ramp WIM systems must also meet the following specifications:

The Ramp WIM System shall be capable of activating beacons that direct traffic to report to the scale house or to return to the highway bypassing the weigh station.

Proposers shall provide manufacturer’s name, model numbers, catalog sheets, operational descriptions, warranties, installation kit components, and other descriptive literature of all devices required to collect, store, and communicate the data listed above that the proposer is able to supply to the Agency if awarded. Proposals shall include major components such as controllers, converters, modems, 915 MHz antennas for transmitting and receiving, etc. to prove that these data types are able to be collected and communicated by the proposed WIM system. System architecture diagrams shall be provided to describe how the components integrate together to provide a complete system.

Sensors and cameras required to provide the required data types for the systems will be evaluated in Section 2 Requirements of the WIM Sensors and Cameras and Attachment I Equipment Desired Specifications and do not need to be submitted for this section.

1.2 WIM System Communication: The weigh-in-motion system must be capable of communicating via Ethernet to Agency owned custom data collection systems. Proposers shall submit one of the following:

Option 1: A statement saying they are currently capable, or can be capable within 6 months of Award, to provide data from the WIM system via a raw socket XML data stream. Agency specific XML protocol may be available upon request.

OR

Option 2: Proposers shall provide the communication method and protocol of their WIM system including camera images. The communication method may be a different protocol to communicate with the roadside device or a new central collection system that can be supplied by the Proposer. The Proposed solution will be evaluated by ODOT to determine if integration to Agency collection systems is feasible and cost effective. Additional questions from Agency may be required to fully understand communication method.

SECTION 2: Requirements of the WIM Sensors and Cameras The Proposer shall provide a list of all sensor and camera equipment able to be provided upon Award that are compatible with the proposed Mainline WIM and Ramp WIM Systems. Proposers shall include the component’s manufacturer name, model numbers, specification sheets and/or other descriptive literature of materials able to be supplied. The catalog sheets and literature must include technical data, physical properties, and operational description in sufficient detail to demonstrate the equipment specifications.

The WIM system sensors and cameras shall be either currently integrated or able to be integrated upon Award into Proposer’s Mainline WIM and Ramp WIM systems and shall be supplied by the Proposer.

2.1 Vehicle Weigh-in-Motion Sensor: The WIM sensor shall be minimally invasive in the pavement and be able to be installed in less than 6-inch wide cavities. The sensor shall meet the following requirements.

International Organization of Legal Metrology (OIML) R134 Automatic Instruments for Weighing Road Vehicles in Motion and Measuring Axle Loads

2.2 Commercial Vehicle Sensors: The proposer must be capable of supplying sensors that collect the following data types from commercial vehicles. Data can be collected from a single or multiple sensors to receive points, such as inductive loops, weigh-in-motion sensors, and radar. All sensors required to achieve these data types must be submitted and proposers must describe which sensor or combination of sensor is used to achieve each measurement type.
