The volume contains a detailed technical description of roadside and vehicle-mounted data collection and recording systems developed to measure such parameters as passing car speed and position relative to the road and to other vehicles, various passing-car dynamic parameters, lateral position of the passing car on the roadway, and longitudinal position data, whether or not the driver passed, vehicle speeds, reaction time, passing time, and safety margin. Instrumentation included sensors, transducers, a magnetic-loop detection system, a photocell system used in conjunction with a fifth wheel, event recorders, and stopwatches. Among the dynamic passing car variables capable of being measured by the described equipment are steering wheel, throttle, and brake pedal activity, heading rate, and lateral and longitudinal acceleration.
