摘要：	Over the past several decades, the Texas Department of Transportation (TxDOT) has made a significant investment in deploying and developing intelligent transportation systems (ITS) devices, such as closed-circuit television (CCTV), traffic sensors, and dynamic message signs (DMS), to assist in managing traffic operations. However, as these systems have matured and as financial resources have become more constrained, TxDOT needs to become more strategic in their decision-making as to when and where to deploy new ITS devices and systems and when and where to continue supporting and/or upgrading systems that have met their life expectancy. The goal of this project was to develop guidelines, criteria, and procedures to assist TxDOT in their decision-making specific to installing, repairing, and/or removing ITS field devices and systems. Specifically, through this project the research team assisted TxDOT by: (1) developing warrant conditions and criteria for assessing when and where to install new ITS devices and systems, (2) providing sunset requirements and criteria for determining when to no longer support deployed ITS devices and systems, and (3) developing an analytical framework for identifying and prioritizing mission-critical devices and systems for upgrade and maintenance.
