摘要

Using traffic control devices and communications equipment to monitor and control arterials and freeways has brought with it new challenges and a demand for new skills. Many systems and equipment procurements have occurred without clear traceability between agency needs and potential solutions. A common result has been that agency needs are not satisfied. Such a procurement environment, where no direct traceability (or a weak association) between agency needs and provided solutions, often leads to project cost overruns, late delivery and even failed projects. Applying systems engineering methodologies and incorporating ITS Standards that contain user needs, requirements, and design solutions into the procurement process will mitigate the risk of not satisfying agency needs. This paper presents a description of the problem, and a description of a life-cycle process that uses systems engineering methods proven to satisfy agency needs when deploying ITS Standards. This paper also provides lessons learned and suggestions for success, and benefits of these methods. Examples of how the life-cycle process and the systems engineering methods were applied are taken from the NTCIP 1203 Dynamic Message Sign (DMS) version 02 Standard Implementation Project, sponsored by USDOT and VDOT/VTTI.
