ABSTRACT
Often commuters encounter intersections which operate near capacity limits and do not know when they will experience unacceptable traffic conditions. There are days where they drive through such intersections without major disruption and days on which they do not accept adverse traffic conditions, which can be expressed by means of a variety of measures including delays, queues, stops etc. [Chodur 2004]. For each driver the ability to estimate the likelihood of favourable traffic conditions at the time of departure and select the best route is extremely important in terms of minimizing trip time. The aim of this paper is to show the application of elements of reliability theory to the description of the functioning of a lane with a left turn at a signalised intersection in Krakow over several successive working days in favourable weather conditions. The analysis will cover 24-hour periods and record moments in time in which there were adverse traffic conditions from the viewpoint of drivers. Lane’s functioning is associated with the level and quality of service and is renewable in time. The concept of renewal in this case is directly related to theoretical renewal, when a renewed object reveals the same reliability as directly before the overload.
