Puyallup ASCT System Verification Plan 1 1. Purpose of Document The purpose of this document is to layout the verification plan of the adaptive signal control technology (ASCT) that will be implemented at the City of Puyallup. This document is part of the System Engineering documents that have been developed to select and deploy an ASCT system for the City. This document describes the scope of the project; the referenced documents that are used to prepare the verification plan; details on the actual conduct of verification; and provides a list of the verification cases and corresponding system requirements to be tested. The intended audience of this document includes the existing stakeholders of City of Puyallup signal system: • City of Puyallup • WSDOT • FHWA • Network Users • City of Puyallup IT Department 2. Scope of Project The scope of the project includes the implementation of adaptive signal control technology at 17 intersections along the Meridian corridor and the bypass corridor in the City of Puyallup. The adaptive signal control technology will improve the traffic operation and reduce or eliminate the limitations of the existing signal control system. Each of the system requirements of the selected adaptive signal control technology will be tested according to this verification plan. The results of the verification tests will be documented by the verification conductor. If any test fails to provide satisfactory result, the reason of the failure and the resolution of the corresponding issue shall be documented by the verification conductor. 3. Referenced Documents The following documents supported the preparation of the verification plan: FHWA-HOP-11-027: “Model Systems Engineering Documents for Adaptive Signal Control Technology (ASCT) Systems”, August 2012 City of Puyallup Adaptive Signal Control Technology – System Requirements, March 2014 City of Puyallup Adaptive Signal Control Technology – Concept of Operations, March 2014 4. Conducting Verification The verification will be conducted by the system vendor in presence of the City of Puyallup system operator. The vendor shall conduct the verification tests in two steps. In the first step, the vendor shall bench test the system requirements for each signal at the City signal shop. In the second step, the vendor shall conduct the verification tests in the field. The verification table below indicates where the ---PAGE BREAK--- Puyallup ASCT System Verification Plan 2 test should be conducted. The vendor shall coordinate with the system operator to schedule the testing time periods. The verification conductor will fill out the verification identification document to include the test results. Any failure or lack of performance to meet the stated system requirements shall be immediately recorded and the vendor shall prepare a report stating why system requirement was not met. The report shall include a proposed solution to resolve the deficiency and shall be submitted to the City within seven days of the failure if discovered. If the vendor is not able to meet a system requirement that was included in the vendor contract, the vendor shall prepare a report and develop a plan to provide similar performance operation. The City does not anticipate any software revision would be required to satisfy the mandatory requirements. Upon completion of all required verification testing, the vendor shall prepare a final Verification Report which will contain all critical information regarding testing conducted including both failures and successes. Resolution of the cause of failures should also be detailed. A list of all hardware, software and special equipment utilized in the testing shall be provided. 5. Verification Identification The following verification cases shall be tested and documented by the verification conductor. Each verification case consists of the group of system requirements that satisfies an operational need of the system operator. The needs of the system operator are described in the Concept of Operations documents. The verification plan does not include the verification procedure. As a result, the verification tests are not grouped by action procedures. The verification conductor is allowed to rearrange the verification tests by the action procedures. The verification conductor shall provide the action procedures for the tests and logical grouping of the tests (if re-arranged) to the City for review and approval before conducting the verification. ---PAGE BREAK--- Puyallup ASCT System Verification Plan 3 Verification Case Number (Con Ops Reference Number) Verification Case (Concept of Operations Sample Statements) City of Puyallup Adaptive Signal Control Technology (ASCT) System Requirements Test Location Pass/Fail Briefly discuss the reasons if the verification test fails an how the issue will be resolved 4 4 Operational Needs 4.1 4.1 Adaptive Strategies 4.1.0-1.0-1 Maximize the throughput on coordinated routes 2.2.0-4 The ASCT shall calculate offsets to suit the current coordination strategy for the user-specified reference point for each signal controller along a coordinated route within a group. 2.1.1.0-7.0-1 When current measured traffic conditions meet user-specified criteria, the ASCT shall alter the state of signal controllers, maximizing the throughput of the coordinated route. 2.1.1.0-7 The ASCT shall alter the adaptive operation to achieve required objectives in user-specified conditions.
