Abstract Every time an individual crosses a city street, it involves a risk management decision. Is the light green? How fast is the traffic coming? How important is it to get across the intersection quickly? Is there a 1, 000 bill laying on the curb? Is the person being chased by a man with a gun? All these considerations are analyzed in a split second and the decision is made: cross the street now, even against the light; or wait until the “walk” sign lights up.
