STREAMLINING COLLECTION AND PROCESSING OF TRAFFIC COUNT STATISTICS (DISCUSSION) (CLOSURE)

Traffic volume counts provide basic information for transportation analysis and forecasting, as well as for facility design, monitoring, and operation. The traditional methods of organizing a traffic count program have changed little since 1965. Basically, they include a system of continuous counter stations for developing seasonal adjustment factors, seasonal control stations to aid in factor development as well as determining the seasonal assignment of coverage count stations, and the coverage count stations themselves. Such a program works well but is quite costly. Thus, the New York State Department of Transportation examined its program and procedures and looked at new technology to streamline the process and reduce costs. Seasonal adjustment factors for coverage counts were revised and the number of factor groups was reduced. The method of determining which sections should be counted was also revised, based on changes in traffic volumes, and telemetry systems and methods of collecting additional traffic data (truck weight, vehicle classification) were examined. Implementation of these improvements yielded a 35 percent reduction in counting with little or no loss of information.
