Street traffic control by electrically-operated equipment

Public streets are considered one of the most valuable utilities possessed by a community under present-day conditions, and in business operations their use is all important. Heavy investment of public funds is necessary for the construction and maintenance of streets, and to obtain a maximum return on this investment they must be utilised with a maximum of efficiency. An important factor is the time required for traffic movement; the more expeditiously both vehicular and pedestrian traffic is moved, the greater the return on the investment. Public convenience, how-ever, demands consideration, and the speed of movement should be the maximum con-sistent with safety and efficiency.
