The Video Detection System shall provide a level of accuracy of less than 5% error rate based on volume counts for the entire field of view compiled over mu ltiple time intervals that contain a minimum of 300 vehicles.

Stopped Vehicle Detection - The Vehicle Detection System shall be capable of detecting 95% of all vehicles stopped on the shoulders or in lanes and triggering an alarm. Because of the possible dangers to motorists and workers during this test, the test will be completed after operation has been enabled.

This test will be performed on all of the video detection system installations up to five (5), or on a random sample of five (5) if the total number of Video Detection System installations is greater than this. If all parameters are met for all locations tested, all that are in stalled on the project will be considered acceptable.

If a failure in the second set is recorded, the Contractor will be required to take remedial action until a pass of five (5) locations is achieved. Speed - The system shall provide an average vehicle speed measurement within ±10% of actual speeds. These levels of accuracies shall be provided for traffic traveling between 20 and 75 mph. These levels of accuracies sh all be provided during both day and night conditions. Personnel participating in and observing these tests will use either radar detectors or probe vehicles to conduct this accuracy demonstration. This test will be performed after the system is in operation as de scribed in the stopped vehicle tests. Failure to achieve accuracy will require remedial/corrective action by the Contractor and repeated testing until accuracy is achieved. Other Parameters (Occupancy, Flow Rate, H eadway, and Density) - If the measurements of speed and volume as described above fall within acceptable specified limits of accuracy, and the system is demonstrated to be able to provide the calculated values for these parameters, no further testing will be required.

The Project Engineer and/or authorized represen tatives are only responsible for attending and observing each test, and reviewing and approving the Contractor's test results documentation. The Project Engineer and/or authorized representatives reserve the right to attend and observe all tests. Each test shall fully demonstrate that the equi pment being tested is clearly and definitely in full compliance with all project requirements. Test procedures shall be submitted and approved for each test as part of the project submittals. Test procedures shall include ever y action necessary to fully demonstrate that the equipment being tested is clearly and definitively in full compliance with all project requirements. Test procedures shall cross-re ference to these Technical Specifications or the Project plans. Test procedures shall contain documentation regarding the equipment configurations and programming. No testing shall be scheduled until approval of all project submittals and approval of the test procedures for the given test. The Contractor shall provide all ancillary equipment and materials as required in the approved test procedures. The Contractor shall request in writing the Project Engineer's approval for each test occurrence a minimum of 14 days prior to the requested test date. Test requests shall include the test to be performed and the equipment to be tested. The Project Engineer reserves the right to reschedule test request if needed. All tests shall be documented in writing by the Contractor in accordance with the test procedure and submitted to the Project Engineer within seven (7) days of the test. Any given test session is considered incomplete until the Project Engineer has approved the documentation for that test session. All tests deemed by the Project Engineer to be unsatisfactorily completed shall be repeated by the Contractor. In the written request for each test occurrence that is a repeat of a previous test, the Contractor shall summarize the diagnosis and correction of each aspect of the previous test, which was deemed unsatisf actory. The test procedures for a repeated test occurrence shall meet all the requirements of the original test procedures, including review and approval by the Project Engineer and ITS Manager. The satisfactory completion of any test shall not relieve the Contractor of responsibility to provide a completely acceptable an d operating system that meet s all requirements of this project.

643.03.3 2--Factory Acceptance Test (FAT). Factory Acceptance Tests shall be

conducted at the Manufacturer or Contractor facility or at a facility acceptable to all parties.

complete SAT on all equipment and materials associated with the field device site, including but not limited to electrical service, conduit, pull boxes, communication links (fiber, leased copper, wireless), control cabl es, poles, etc. A SAT shall be conducted at every field device site. Where applicable, a SAT shall be conducted for a fully installed and completed connection to the designated Tr affic Management Center (TMC) or central data/video collection site. The SAT shall demonstrate that all equipment and materials are in full compliance with all project requirements and fully functional as installed and in final configuration. The SAT shall also demonstrate full compliance with all operational and performance requirements of the project. All SATs will include a visual inspection of the cabinet and all construction elements at the site to ensure they are compliant with the specifications. All SATs will include videos of the approach with detec tion zones overlaid showing detector activations.

1.One (1) hour videos shall be made of each approach and compared to actual detection calls.
2.30 minute videos shall be made starting 15 minutes prior to sunrise and sunset for each approach and compared to actual detection calls.
3.All videos shall be date and time stamped.
4.Provide all videos to the Engineer with a summary of the results included total calls, missed calls and false calls.
5.All test results must meet a 98% accuracy requirement. The Contractor must demonstrate the accur acy requirements specified in Subsection

643.02.1 7 at selected intersections after a sixty (60) day burn in period for Type 1 and a thirty (30) day burn in period for Type 2, Type 3 and MSDS. The intersections to be tested will be randomly selected by the Project Engineer.

643.03.4 Warranty. The Video Detection System shall be warranted to be free of manufacturer defects in materials and workmanship for a period of one (1) year from the

date of final acceptance. Equipment covered by the manufacturer's warranties shall have the registration of that component placed in the Department's name prior to final inspection. The Contractor is responsible for ensuring that the vendors and/or manufacturers supplying the components and providing the equipment warranties recognize the Department as the original purchaser and owner/end user of the components from new.
