New Methods to Quality Check Road and Weather Observations for Vehicle Data
The FHWA’s Connected Vehicle (formerly IntelliDrive) research project initiative for mobile data collection from consumer automobiles requires knowledge and trust in the quality of data coming from these vehicles. Connected Vehicle is designed to create a fully connected transportation system to provide road and weather data collection from an extensive array of vehicles. While the implementation of Connected Vehicle is in the future, some of the elements and technologies are already in place today. Since 1996, automobiles sold in the United States are required to be equipped with an Onboard Diagnostic Version 2 (OBDII) port that streams live data from sensors located onboard the vehicle. While these sensors were designed for vehicle diagnostics, some of the data can be used to determine weather characteristics around the vehicle. The OBDII data can be collected by a smartphone and sent to a server in real-time to be processed, thus providing a test bed for research into potential applications of mobile data. Some initial studies raise the question about the quality and biases from the OBDII data. Over time, effective operational techniques for stationary atmospheric sensor data have been developed; yet, no techniques exist for operational quality control of surface mobile data. Current methods of road weather data reporting have been limited to static in situ sensor stations. These road weather information systems (RWIS) provide varied data about precipitation, winds, temperature, road conditions, and more, but their siting does not always provide an accurate representation of weather and road conditions along the roadway. The use of mobile data collection from vehicles travelling the highway corridors may therefore assist in the locations where RWIS sitings are sparse or nonexistent.
