Aurora Project 2003-02 – Off-the-Shelf Component RWIS
Project OverviewThe objective of this project was to build an RWIS station with an open architecture, in order to utilize various sensors from different manufacturers. As noted in the final report, the open RWIS platform was essential to test the performance of different sensors.
Abstract:RWIS are sold by most vendors as an integrated package. Vendors integrate a suite of sensors, a data acquisition system, and a communication and display system that is provided in a turn-key format. This restricts the ability of the highway agency to select competing components that may have preferred qualities, or to update the system as new hardware or software components are developed. The purpose of this project was to develop a programmable, off-the-shelf RWIS that allows choice of initial sensors, and the ability to change sensors or other components over time without completely replacing the system. The methodology for this project involved review and selection and data acquisition systems to meet the following requirements: Sensors should be easily interfaced with a data acquisition system and should provide good functional performance and complete documentation to allow interfacing with alternative Remote Processing Units (RPUs). RPUs or data acquisition systems should have open programming and provide inputs to the desired sensors types.
