Verification of Methodical Procedure for Determining the Traffic Volumes Using Short-term Traffic Surveys

This paper outlines the problems of calculating the traffic volumes in Czech Republic. Especially the authors focus on the verification of methodical procedure for the determination of resulting traffic volumes using the short-term traffic surveys. The methodology TP 189 for determining the Annual Average Daily Traffic volumes (AADT) reflects the conversion coefficients which were statistically derived from long-term measurements of traffic intensities. It can be assumed that different traffic characters exist on different types of roads, for which no coefficients are set yet. Authors of the paper use data obtained from real long-term measurements of traffic volumes on the various categories of roads and try to determine categories of roads for which current conversion coefficients to determine AADT cannot be applied
