Widespread deployment of Event Data Recorders (EDRs), sometimes called black boxes, promise a new and unique glimpse of the events that occur during a highway traffic collision. The EDR in a colliding vehicle can provide a comprehensive snapshot of the entire crash event pre-crash, crash, and post-crash. In 2004, an estimated 40 million passenger vehicles were equipped with EDRs. By carefully collecting and analyzing the details provided by the growing number of EDR-equipped vehicles, state transportation agencies, federal agencies, and the highway safety research community have an unprecedented opportunity to understand the interaction of the vehicle-roadside-driver system as experienced in thousands of U.S. highway accidents each year. State and federal transportation agencies can expect both immediate and longer term benefits from the collection of EDR data. The initial benefit for state transportation agencies will be the use of EDR data from individual traffic accident investigations as a powerful new form of evidence in legal proceedings, e.g. to defend against lawsuits or to recover costs of repairing collision damage to the highway infrastructure. With a more methodical system of EDR data collection, state and federal transportation agencies can expand this benefit to significantly improve the efficiency of database collection for accident statistic databases. For example, in state accident databases designed to meet the Model Minimum Uniform Crash Criteria (MMUCC) format, one-third (24 of 75) of the recommended data elements could be provided by EDRs. In the longer term, one of the crucial benefits of EDRs will be their influence on highway crash safety research. The ready availability of EDR data in an accident statistics database will enable highway safety researchers to address a number of elusive research questions which directly affect state transportation agencies, e.g. the relevancy of the NCHRP 350 roadside safety feature crash test guidelines.
