The purpose of the 1972 Traffic Control Devices Survey is to create an inventory of traffic control devices existing in the major street and highway network of Lake and Porter Counties in Indiana. The objectives of the survey are: (1) to establish and maintain a file on traffic signal installations, including their location, layout, type of equipment, operation and other specific details; (2) to establish and maintain a file on other traffic control devices, such as speed control zones, railroad crossing controls, signs, and painted roadway markings; and (3) to check on the uniformity and effectiveness of these devices. This survey is a necessary element of the major street features survey which, in turn, is necessary for the development of comprehensive and general regional transportation plans. This survey manual sets out the rules, methods and procedures in making the survey and coding the data for computer use. It describes (1) the data items to be collected, (2) the procedures used in collecting the data items, and (3) the field sheets on which these data items are recorded. The manual also provides a coding dictionary and an explanation of how to use the dictionary to translate the data on the field sheets into computer code.
