The hypothesis is that the recorded noise-imprints of a vehicle at an intersection can be used to identify and accurately time the driving modes of deceleration, idle, slow cruise, and acceleration. This is proven by analyzing and comparing noise-imprints of vehicles at an uncontrolled intersection marked first with a "stop" sign, and then by a "yield" and an experimental "dead slow" sign. By relating the duration of each driving mode to known relations, the overall efficiency of an intersection can be characterized. A new technique for studying various types of traffic conditions at intersections is the result. Initial noise-imprint analysis and comparison shows that a "yield" sign is to be preferred over a "stop" sign to decrease travel time, air pollution emissions, gasoline consumption, and wear-and-tear on the car. The experimental "dead slow" sign is used as a demonstration of the noise-imprint technique upon an unknown situation. The efficiency of a "dead slow" sign proved to be less than that of a "yield" sign, but still greater than that of a "stop" sign.
