Analysing Application Possibilities of a Foreign Method for Calculating the Annual Average Daily Traffic

This paper on methods used to calculate daily traffic flow is part of the research carried out by the Institute for Transport Studies, Hungary, in 2007. The author describes a new probability-based method used for calculating the Annual Average Daily Traffic (AADT) figures, first presented in January 2005. In Hungary, the AADT figures are estimated based on manual traffic counts over a period of 2 to 5 days, 12 hours a day, at substation networks that make up approximately 85% of the nationwide public road network. In the new method, substations along routes with the same origins and destinations are assigned to one or several main stations with uninterrupted operation. In this method, the generic least square (GLS) technique is used (rather than the traditional estimation method that used the old least squares, or OLS, technique). The new method permits improved estimates for road sections where only a two-day traffic data count is done during the year. The author briefly reviews other steps that would be needed before the implementation of the new estimation method.
