Abstract:Connected vehicle wireless data communications can enable safety applications that may reduce injuries and fatalities suffered on ; our roads and highways, as well as enabling reductions in traffic congestion and impacts on the environment. As a critical part of ; achieving these goals, the USDOT contracted with a Team led by Battelle to integrate and validate connected vehicle on-board ; equipment (OBE) and safety applications on selected Class 8 commercial vehicles and to support those vehicles in research and ; testing 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 the ; truck, its driver, and the safety system. This capability was provided by a Data Acquisition System (DAS) installed on each of the test ; vehicles. The DAS communicated with the OBE safety equipment, the vehicle’s internal data bus, a set of accelerometers, and four ; video cameras. It recorded all of the Basic Safety Messages (BSMs) transmitted by the OBE and the BSMs that the OBE received ; from other units. ; This document describes the design of the DAS, its specifications, and instructions for operating it.
