Modeling the Participation of Heavy Vehicles Stream, Using the System of Automatic Weigh Control of Vehicles in the City of Gdynia

The article presents the pilot system of automatic weigh control of vehicles in the road, which is implemented in Gdynia City on Janka Wisniewskiego Street as a source of measurement data to analyze the use of stretch of road by heavy vehicles. The measuring point is located on the road leading to the Gdynia's container terminals and to the Kwiatkowskiego Street, which is directly connected with Tri-city bypass [11]. Measurement period allowed developing a mathematical model defining the load of the network by heavy vehicles. By adopting a semi-Markov model for system state changes, we must map the probability matrix of the transitions and the kernel of the process. Based on measurements from the weighing preselection system, we determined the probability matrix of the transitions. Using the appropriate failure statistics, you can develop possible failure scenarios and determine the reliability indicators of the system.
