DEVELOPMENT AND EFFECTIVENESS OF STANDARDS FOR REFERENCE ROAD SECTIONS AND APPLICATION TO THE ROAD TRAFFIC CENSUS

Abstract

While traffic surveys at arterial roads around Japan are conducted by designating survey sections, methods for the designation often vary annually and depending on types of survey. This condition has been requiring substantial labor for mutual uses of survey outcomes and comparative analyses. In addition, the conventional methods were not useful for those who work on data to analyze traffic survey outcomes at a network level and efficient updating of data obtained from road sections.
In order to eliminate these problems, this paper proposes standard reference road sections for road surveys that are compatible with the needs for traffic surveys and analyses, self-explanatory and easy to understand, and great for long-term data stability as well as standard reference intersections which can be primarily derived from the standard reference road sections. The paper then describes specific contents of these standards. In addition, this paper clarifies that efficient uses of these standards enable mutual uses of various types of traffic survey outcomes and improve the efficiency of data processing such as data sorting by intersections and network analyses.
