Recommendations for new capacity values on freeways

Abstract

By the analysis of the traffic data collected loop detectors we can get information about the capacities of different freeway sections. The results and the analysis of the measurements able to show the real maximum traffic volume:2300-2400 pcphpl. According to the recent regulations the maximum tolerable traffic volumes are much lower than these and lower than 2200 (capacity in HCM). We recommend using the HCM capacity values and the HCM Level of Services (LOS) categories in Hungary. By these 20%higher capacity value are more rational from the point of view of the national economy.
