Abstract

This report discusses the following topics in the light of accumulated experience and available data: toll bridges and toll highways traffic planning as an engineering problem type of transportation to central business areas motor vehicle parking or stopping installation of traffic control signals operation of traffic control signals train actuated signals at grade crossings vehicle actuated traffic control signals signalizing of main arteries results from elimination of parking on city streets theoretical limits of traffic capacity measure of traffic congestion traffic lane markings responsibility for providing for pedestrian traffic left turns independent routes for high and low speed traffic forms for traffic investigation. Important conclusions are: (1) it is not the responsibility of the public to provide either curb parking or vehicle storage space, (2) advance signals should be used with train actuated crossing signals, where 500 clear feet view is not possible, (3) traffic control signals should not be used to control traffic at intermediate intersections, (4) left turns at intersections should be made on the inside with the green light.
