DEVELOPMENTS IN POLAND ON A METHOD OF TRAFFIC CAPACITY ESTIMATION AND EVALUATION OF TRAFFIC CONDITIONS ON OUT-OF-TOWN ROADS

This paper presents a new perspective on forming the fundamental traffic dependencies, which describe the formula between density, volume and speed for various characteristics of a road and its traffic. These dependencies were the basis for developing the first version of the new Polish method of estimating traffic capacity and evaluation of traffic conditions on out-of-town roads. The analyses described above are based on the results of research into road traffic that had been lasting for a number of years. The main point of the traffic model presented is the adoption of a free flow equation (defined by the author as a relation between average speed and the average effective unit power indicator of vehicles) and the overtaking demand indicator and the overtaking opportunities (also prepared by the author) as the basis for determining all traffic characteristics, including capacity.
