System Readiness Level Model of Highway Intelligent Transportation System by Integrating a Value Engineering Process

Emerging technologies, like cloud computing, artificial intelligence (AI), and internet of things (IOT), are advancing the evolution of intelligent transportation systems (ITS). For successful technology integration, researches on ITS engineering often apply theories and tools of system engineering, among which system readiness level (SRL) is a fitting tool for system development. This paper built a model based on SRL analysis for highway ITS engineering. Further, the author analyzed the spatiotemporal features of highway ITS, including distributed computing resources and network capabilities, unbalanced development of existing information and communication technologies (ICT), and inherited architectural limitations of existing ITS infrastructures. The analysis indicated the need for economic consideration on highway ITS engineering. Therefore, this paper improved the SRL-based engineering model with a value engineering process. The effectiveness of the model was verified by the deployment of 5.8GHZ ambiguity path recognition technology, from aspects of system development and economic efficiency.
