Abstract

During the fall of 1957 the bureau of public roads in cooperation with the Illinois and Michigan state highway departments, the cook county and wayne county highway departments, and the city of Detroit, department of streets and traffic, conducted driver behavior studies at a number of locations on freeways in the Chicago and Detroit areas. Some of these were lighted and others unlighted. Driver behavior at night on the lighted and unlighted sections will be compared with the daytime behavior.
