Federal Transit AdministrationFederal Highway AdministrationConnected vehicle wireless data communications can enable safety applications that may reduce injuries and fatalities suffered onour roads and highways, as well as enabling reductions in traffic congestion and impacts on the environment. As a critical part ofachieving these goals, the USDOT contracted with a Team led by Battelle to integrate and validate connected vehicle on-boardequipment (OBE) and safety applications on selected Class 8 commercial vehicles and to support those vehicles in research andtesting activities that provide information and data needed to assess their safety benefits and support regulatory decision processes.An essential element of the developmental testing of these safety devices is the ability to record and examine the operation of thetruck, its driver, and the safety system. This capability was provided by a Data Acquisition System (DAS) installed on each of the testvehicles. The DAS communicated with the OBE safety equipment, the vehicle\u2019s internal data bus, a set of accelerometers, and fourvideo cameras. It recorded all of the Basic Safety Messages (BSMs) transmitted by the OBE and the BSMs that the OBE receivedfrom other units.This document describes the design of the DAS, its specifications, and instructions for operating it
