Connected vehicles (CVs), travelers using connected mobile devices, intelligent transportation system (ITS) devices, and traffic management systems sharing and using SAE J2735 basic safety messages (BSMs) and other CV messages have the potential to transform transportation systems management, traveler safety and mobility, and system productivity.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 997: Algorithms to Convert Basic Safety Messages into Traffic Measures is designed to help position state and local transportation agencies to take early advantage of BSM data, reduce costs, improve accuracy, and add new measures to their systems management capabilities.
