Riding Out the Storm

摘要

Every year, adverse road weather results in about 6,000 fatalities nationwide and costs more than 32 billion hours of delay among commercial vehicle operators. Improved traffic management strategies during weather events can reduce crashes and resulting delays, but limitations in data coverage and quality have constrained their effectiveness. Specifically, sparsely located road weather sensor stations have prevented agencies from gathering the site-specific information on road weather conditions needed to make informed decisions regarding traffic management and maintenance.
