Results of studies of delays at some chosen intersections in Poland are presented. The researches were conducted by using a Pentaflex 16-mm camera. As well as delays, the distribution of the arrivals of vehicles was investigated. On the basis of the results of the studies of arrivals, three hypotheses have been put forward for the theoretical distribution of arrivals of vehicles and these hypotheses have been statistically verified. The analysis of vehicles passing through intersections made it possible to fix the lost time and the saturation flow for traffic conditions in Poland. On the basis of these parameters the departure pattern of vehicles has been formed. A simulation model, which was used to estimate delays and passenger car equivalents describing the effect of traffic composition on delays, is presented. The results of the studies of delays have been compared with Miller's first equation and with webster's modified equation. From this comparison, methods of practical usage of these theoretical equations are suggested. (Author/TRRL)
