Evaluation of the Traffic Count Program

Report No: 79-R14

Published in 1978

About the report:

The purpose of this study was to determine the Department's needs for traffic count data, to relate them to an evaluation of the traffic count programs and procedures, to identify problems and deficiencies with data requirements, and to seek means of improving the programs. In approaching these objectives, interviews were conducted with representatives of the Department who supply and use volume data. The field collection operations were reviewed and the mechanical traffic recorders used by the Department were evaluated for accuracy and reliability. The study concluded that the data provided by the count programs are not sufficient to fulfill the requirements for transportation planning and environmental studies in the urban areas of the state. In the rural areas, an excessive amount of data are acquired and the accuracy of the data is questionable. Specific problems, deficiencies, duplications, etc. in the count programs are identified in the report and recommendations for improvements are presented.
