 This paper proposes a method for determining delay times at unsignaled intersections based on the theory of stationary Poisson flow and prioritizing different types of traffic. To test its accuracy, the authors compared the average delay times of vehicles making a left turn from a minor road with the actual delay times measured in field studies. The results showed that the calculated delay times were reliable, with errors no greater than 10%. Additionally, this method can be used to model unsignalized intersections and inform transportation planning. This article was authored by Ole Bialetska, Yevon Lubyai, Sarai Okorotenko, and others.
