Abstract:Without standardized vehicle data formats from all vehicles, off-the-shelf CAN-Bus technology is not adequate for collecting a complete and robust vehicle data set. Federal requirements are addressing this issue; however, the circumstances make proactive and advanced research difficult. Even with an adequate data set, this research indicates there is some concern with translating vehicle CAN-Bus data into mobile weather information. The practicality and usability of NCAR’s Pikalert system needs to be evaluated further to fully comprehend the potential for segmented road weather condition data. The current system appears to be very successful in producing and distributing road condition advisories and warnings; however, success in producing raw segmented road condition data is unclear. Further, the next steps should be to evaluate complete vehicle data sets during adverse weather events and evaluate the data collection process and Pikalert system to a greater extent.
