Abstract:The Louisiana Department of Transportation and Development (DOTD) established Intelligent Transportation System (ITS) programs over 20 years ago. Before DOTD expands or implements new ITS programs, a study needed to be undertaken to evaluate the performance of the current ITS programs to demonstrate their benefits. The primary objective of this research was to develop a set of performance measures for each existing ITS program in Louisiana and evaluate the benefits achieved through their implementation. The scope of this study was to use insights gathered from literature reviews, qualitative surveys, and inputs from stakeholders to develop performance measures for Louisiana's ITS applications. The scope also included using data from ITS applications in Louisiana to evaluate the performance of the deployed system and determine if the ITS applications were beneficial to the taxpayer. The ITS programs were grouped under six broad areas: Arterial Management; Commercial Vehicle Operation; Electronic Payment and Congestion Pricing; Freeway Management and Traffic Management Centers; and Traveler Information. For each program area, specific objectives linked to specific transportation goals that Louisiana needed to achieve were developed, along with performance measures to evaluate the state’s efforts at meeting each goal. Data mainly between 2016 and 2020 were collected and used for the assessment. Overall, the benefits achieved through the implementation of some of the ITS programs were apparent, while in other cases, further studies are required.
