Introduction It is the intent of these specifications to establish the minimum requirements for high speed weigh-in-motion equipment utilized the purpose of collecting traffic data at Long-Term Pavement Performance (LTPP) Specific Pavement Studies (SPS) sites.

High Speed Weigh-in-Motion System The Weigh-in-Motion System (hereafter WIM system) shall include equipment and software for collecting, processing, storing, transmitting and manipulating information related to the counting, classifying and speed monitoring of all vehicles and the weighing of trucks and buses at highway speeds.

The WIM system shall provide for single threshold weighing, and operate over a speed range of 5 mph to 100 mph. Single threshold weighing shall consist of scales in each lane of measurement. The weigh sensors shall cover the entire lane width. The WIM system shall consist of the following components:

1. Wheel scales shall report weight data for each wheel track (right axle weight and left axle weight). Such wheel weight data shall be uniform across the total width of the scale.

2. A WIM controller shall be installed in the controller cabinet. The WIM controller shall include all of the equipment and software to calculate, store and transmit to a host computer all data specified in these specifications. Either a keyboard and monitor or a portable personal computer (including protective case) for the purpose of accessing the WIM controller shall be furnished as part of the WIM controller.

The WIM controller shall operate on AC power with a DC battery backup system to provide uninterrupted power to the WIM controller during AC power outages for a minimum of one hour. The system shall be able to operate on solar power if AC power is unavailable. The modem to be installed in the controller cabinet shall be compatible with the host computer modems described elsewhere in these specifications. The user shall have the capability of entering a site designation code up to three characters.

3. Surge protection devices against lightning and other transient high voltage consisting of:

Power Source Protection Phone Line Protection Loop Input Protection WIM Sensor Protection Grounding All conduit shall be metal and bonded with #8 bare copper wire.

A ground rod with an impedance of 10 ohms or less shall be placed at the cabinet foundation.

The ground rod shall be connected to the electronics backplane with #6 bare wire.

If solar powered, a lightning rod shall be placed on top of the solar panel pole, and shall be independently grounded.

4. All necessary interconnecting cables and miscellaneous materials to make an operational system.

Functional Requirements

1. The WIM system shall be able to accommodate vehicles and vehicle combinations with up to eleven axles and shall automatically determine the following for each vehicle, by lane of travel:

Weight of each axle by left and right wheel weights, speed, axle spacing, and vehicle length. The

WIM system shall provide for calibration features such that the accuracy required under LTPP standards for equipment performance verification can be met

Vehicle Classification. The WIM system shall provide for a minimum of 15 vehicle classifications.

Class 1 through Class 13 shall be used according to the classification scheme shown in Section 4, Appendix A, of the Federal Highway Administration 3d edition of the Traffic Monitoring Guide, February 1995. Class 14 will identify special vehicles as determined by the user. Class 15 will identify any vehicle not conforming to the classification criteria for Classes 1 through 14. Classification criteria for Classes 1 through 14 shall be programmable by the user. The WIM system shall provide sufficient flexibility in spacings and weights (axle and/or gross) for each of these classes so that accurate classifying is achievable.

Invalid Measurements. An “invalid measurement” code shall be assigned to any vehicle meeting the front axle weight threshold (discussed below) when (1) the left and right wheel weights of any axle have a difference of 40 percent or more; and (2) either of the wheel weights of such axle exceeds 2.0 kip. Both the 40 percent and 2.0 kip values shall be programmable by the operator. Any vehicle assigned an “invalid measurement” code shall not be considered a “Weighed Vehicle” but shall be classified and counted and all vehicle data shall be stored in the vehicle record.

Determination of Weight Violations. For any vehicle meeting the front axle weight threshold (discussed below), the WIM system shall determine which, if any, axle(s) or axle grouping(s) exceed the weight limits set forth in the “Weight Violation Table” contained in these specifications. Any vehicle with one or more weight violations will be coded as to such a violation or combination of violations. The weight limitations set forth in the “Weight Violation Table” shall be the default settings. Such weights shall be programmable by the user.

2. The WIM controller shall calculate and store all specified data on a storage medium. The on-site data storage device shall have the capacity to store a minimum of fourteen days of vehicle count data and individual vehicle records. The storage device shall be completely solid state with no mechanical components and shall be a type not susceptible to loss of accumulated data should electrical power be interrupted. The WIM controller shall continue to calculate and store data for all vehicles passing through the system during periods of access, both on-site by portable PC and by the host computer for purposes of programming, real-time view and downloading of data.

The WIM controller shall store the following data:

Hourly vehicle counts by lane, by class and by speed range for each 24-hour period (Class/Count

Summary).

Individual vehicle records for all vehicles with a front axle weight greater than 3.5 kip (hereafter referred to as “truck records”). The front axle weight threshold for truck records shall be programmable by the operator with 3.5 kip as default setting. Each truck record shall include, as a minimum, the following data:

Time and Date Lane Number Vehicle Number Speed Vehicle Classification Weight in kips of each wheel or dual set of wheels by left and right side and by axle number Spacing in feet between each sequentially numbered axle Overall length of each vehicle or combination of vehicles in feet Code for weight violation(s) Code for invalid measurement(s)

3. Data shall be calculated and formatted such that all data can be accessed and all required reports can be generated by use of the WIM system application software.

4. All equipment with exception of the WIM controller’s modem shall operate properly within an atmospheric temperature range of -40°C to +70°C or –40°F to 158°F without the need of an added heating or cooling device.

5. The WIM controller shall have the communication capabilities to allow off-site personnel to view the operation of the WIM site and to allow for data transfer through telemetry over a dial-up, voice-grade telephone line. The WIM controller’s modem shall be fully compatible with the host computer modem.

The reports shall be printed in condensed print when necessary to fit on 8-½ inch x 11-inch sheets. The program shall provide for the generation of reports in the following two modes:

Manual Mode. For daily reports the program shall provide for user selection of the date and the specific report. For monthly reports, the program shall provide for user selection of the month/year and the specific report. The selected month report shall include the data from all downloaded daily data files resident with the system program on a directory or subdirectory of the host computer’s storage medium. The program shall also provide for user selection of the lane or lanes to be covered by the specific report (not applicable to the “Distribution of Class and Speed Counts by Lane,” “the Distribution of Vehicle Counts by Hour of Day by Lane,” and the “Distribution of Truck Record Data by Lane” reports). The default shall be “all lanes.” The printed report shall note which lanes are represented.

Automatic Mode. The program shall provide for user designation of one or a combination of the specific daily reports for automatic processing. User selection of lane or lanes is not required (the “all lanes” default may be used). User selection of vehicle status for the 18 kip ESAL report is not required (the “all” weighed vehicles default may be used). Such designations shall be effected by means of either:

An ASCII text file, which can be revised with text editor or word processor, supplied with a

“Sample” designation; or, A menu selection, which shall provide for user input designation.

Upon selection of automatic mode of report preparation by the user, the program shall send to the printer all pre-designated reports for all downloaded daily data files resident with the system program on a directory or subdirectory of the host computer’s storage medium. The designated reports shall remain in effect for subsequent automatic mode sessions unless report designation, is revised by the user.

Terminate program.

An example of the truck record batch print is included in Appendix A.

ASCII Export Utility The ASCII export utility application shall allow the user to generate specified ASCII files using downloaded files. The user will have the choice of:

Vehicle Class/Count Summary file:

ASCII classification file ASCII speed file

Individual Truck Record file:

ASCII truck record file

The file formats for these files are contained in Appendix A.

Traffic Monitoring Guide Files Utility The TMG files utility shall allow the user to generate ASCII files conforming to the instructions contained in Section 6 of the FHWA Traffic Monitoring Guide 3rd edition using downloaded files.

Data Files Notwithstanding the method of data manipulation and formatting used by the WIM controller, data files shall conform to the following:

Individual daily data files shall be created and stored in the storage medium of the WIM controller.

Each daily data file shall include data for each 00:00 hour through a 23:59 hour period and shall have a file name which uniquely identifies the file as to site designation, date, and file contents (i.e., class/count summary data, individual truck record data, or both).

The daily data files shall be created at the start of each day. Data for each vehicle shall be filed within one hour of the vehicle’s passing through the site, and the current day’s files shall be accommodative to efficient use of storage medium space and rapid downloading via modem to the host computers.

Daily files containing class/count summary data and individual truck records data may be created in the storage medium of the WIM controller as two separate daily files or as one daily file. However, if one daily file is created and downloaded as such, the system program shall create two separate daily files, each with a file name which uniquely identifies it as to site, date and whether it is a vehicle class/count summary file or an individual truck records file.

Acceptance Test The WIM Vendor shall demonstrate that the WIM system is available for use by the owner by successfully completing the acceptance test for each lane of data collection. The acceptance test shall consist of the following:

Verification of WIM System Accuracy Step One. Obtain at least 2 trucks to use for testing the WIM system accuracy. Select truck types that are most representative of the trucks that frequent the WIM location. One of the test trucks shall be a class 9 truck that has air ride suspension for both tractor and trailer, a non-liquid load, and loaded to a minimum of 90 percent of the truck’s legal operating weight. The other truck will be of the 2nd most commonly occurring type of truck, and loaded to 80 – 90% of the truck’s legal operating weight. If the class 9 truck is the most common type of truck at the WIM location, it is OK to use two class 9 trucks for testing the WIM system’s accuracy. No unloaded trucks will be used for testing the WIM system’s accuracy. The procedure for weighing and measuring the test vehicle(s) to obtain reference values is found in sections 7.1.3 to 7.1.3.7 of ASTM E 1318-02:

7.1.3.1 “Measure the center-to-center spacing between successive axles on each test vehicle and record this data to the nearest 0.1 ft (0.03m) as axle-spacing reference values.”

7.1.3.2 “ Weigh each test vehicle a minimum of three times, with brakes released, as described in 7.1.1 and 7.1.2 to measure tire loads for the wheel(s) on each end of every axle on the static vehicle. Move the vehicle completely away from the scale or weigher before beginning a new set of tire-load measurements, and always approach the weighing devices from the same direction for weighing. Sum the applicable tire loads to determine wheel, axle, and tandem-axle loads as well as gross-vehicle weight each time the vehicle is weighed.” (A scale which weighs individual axle and tandem loads is acceptable).

7.1.3.3 “ Calculate the arithmetic mean for all wheel load, axle-load, tandem-axle-load, and gross-vehicle-weight values that result from weighing each test vehicle three or more times; …”

Average the three “static weight values” of the test vehicle(s) for the drive axle-load(s), 1st tandem-axle load(s), 2nd tandem-axle load(s), and gross-vehicle weight(s) to derive the static weights used in the accuracy verification.

Some type of communication, (cellular phone, CB radio, etc.), with the driver(s) of the test vehicle(s) will need to be established before the initial calibration begins.

Step Two. The communications software shall have a history file, (log file), applications which will create a daily file, in an ASCII type format, which chronologically records events occurring during initial calibration runs (and the final verification runs). Such events shall include, but not be limited to, recording the initial calibration factors of the WIM system, the calibration runs, final calibration factors, and any changes made to the calibration factors during the initial calibration runs (and the final verification runs).

Step Three. The test truck(s) is driven over the WIM sensors in each lane a minimum of three times at each set speed point, and three times at each 8kph (5mph) increment between the first and third speed points.

Due to the temperature variations usually occurring during the course of the day, the truck will start at the lowest speed point and continue in sequence to the highest speed point. If the three speed points are set at 40 mph, 55 mph, and 70 mph, then the test truck(s) will start at 40mph and then go in sequence to 45 mph, then to 50 mph, etc., until the 70 mph point is reached. The truck(s) will then start all over again and repeat the same sequence two more times until there are a total of 21 runs for each test truck used in the validation.

The gross weight percent error is calculated for each run and plotted on a “Gross Weight Percent Error by Vehicle Speed” graph for each WIM lane. These graphs are analyzed to make the final adjustments to the WIM weight factors if necessary. They are also used to record pavement effects on vehicle dynamics for the site history.

If for any reason an adjustment needs to be made to the WIM Weight or Spacing factors, before all runs are completed, the validation runs will have to start all over again.

Step Four. Download the data file and close and save the history (log) file. For the site calibration to be accepted, the gross weight percent error of the validation data will have to be evenly distributed around the zero axis of the “Gross Weight Percent Error by Vehicle Speed” graph for each speed point in each WIM lane.

For a Type I WIM System the validation data will meet (or exceed) the functional performance requirements as found in table 2 under Section 5 of the ASTM E 1318-02 of the Standard Specifications for Highway WIM with a 95% Confidence Limit:

o Gross-Vehicle Weight: +/- 10% o Axle-Group Load: +/- 15% o Axle Load: +/- 20%

Continuous operation of WIM system on-site equipment for 15 consecutive days following completion of the WIM system accuracy validation testing. Failure of the system to record and store data meeting the requirements set forth in these specifications for an accumulated time exceeding 3 hours during the 15 day-period shall be cause for the acceptance test to be repeated.

Testing of the WIM system application software during the above noted 15 day-period and the full working day following the 15 day-period. Failure of the software to perform any application meeting the requirements set forth in these specifications shall be cause for the acceptance test to be repeated.

Failure of the host computer or its peripheral equipment or of a communication line not furnished by the WIM vendor to transmit data may not be considered unacceptable performance, provided the WIM vendor demonstrates to the satisfaction of the owner that the failure is not caused by any of the WIM vendor furnished equipment.

Maintenance and Operations Manuals The WIM vendor shall furnish a maintenance manual for the WIM controller, including vehicle detector sensor units and an operation manual for the system. The maintenance manual and operation manual may be combined into one manual. The manual(s) shall include, but need not be limited to, the following items:

Specifications Design characteristics General operation theory Function of all controls Trouble shooting procedure (diagnostic routine) Block circuit diagram Geographical layout of components Schematic diagrams, signal responses and acceptable thresholds List of component parts with stock numbers Documentation for application software
