Winter road conditions are hazardous for drivers to navigate and are a challenge for agencies to manage
This study developed methods to extract on board vehicle data to assess whether current vehicle technologies can provide informative road condition data during winter storms
A laptop was placed in the trunk with an inexpensive controller area network universal serial bus (CANUSB) device, which is a device that feeds the controller area network (CAN) signals forwarded from the various communication buses in the vehicle to the laptop, and is natively supported in Linux as a socket (Hartkopp 2012)
Summary
Winter road conditions are hazardous for drivers to navigate and are a challenge for agencies to manage. According to the US Federal Highway Administration’s (FHWA’s) Road Weather Management Program (RWMP), out of approximately 5,748,000 vehicle crashes each year, about 22% of these crashes are weather related (FHWA 2018). From 2005 to 2014, an average of 445,303 persons were injured and 5,897 persons were killed annually in weather-related crashes. Of these weather-related crashes, 17% of occurred during snow or sleet, 13% occurred on icy pavement, and 14% occurred on snowy or slushy pavement. The estimated annual cost of weatherrelated crashes ranges from $22 to $51 billion (Pisano et al 2008). It is estimated that weather-related delays cost the trucking industry about $8 to $9 billion annually (FHWA 2017a)
