Sign Management


Event data recorders (EDR) monitor and record data of the vehicle, and often are capable of providing information about a vehicle before, during and after a major collision. Understanding how to access, recover, and interpret this data is important to consultants and police involved in collision reconstruction, as well as fleet managers, attorneys, insurance companies and researchers seeking to prevent future accidents. Through Northwestern University’s Center for Public Safety, we offer a training course in Preserving and Analyzing Data from Heavy Truck EDRs. Please visit our Services page for a detailed description of this and the other options we may have to assist with your transportation needs.
