Consumers and fleet managers are progressively installing or requiring the use of after-market onboard vehicle cameras, often with GPS capabilities. Some of these Video, Acceleration, and Position (VAP) devices record kinematic data including position, speed, and acceleration. Many consumers also make use of smart phone applications (apps) which provide similar features. As use of “dashcams” becomes more prevalent it follows that the accident reconstructionist may be called to analyze the video and data recorded by the devices. This study characterizes the accuracy and precision of several VAP devices, including a dashcam with GPS which is used by taxi companies nationwide, and several smart phone apps. Tests were performed in which vehicle kinematic data were recorded in a variety of real world conditions simultaneously by the VAP devices, accelerometers, and a proven GPS-based speed sensing and data acquisition system. Data from the VAP devices was compared to data collected by the reference instruments to assess timing, precision, and accuracy of reported parameters. Still images from the VAP video recording were compared with three dimensional laser scan data in order to analyze field of view, equivalent focal distance, parallax, and lens distortion. Several case studies are discussed, and a method for characterization of other VAP devices is presented.
