The Time Losses as a Reliability of Transport in the Municipal Network during the Mass Event

Abstract

The city of Gdynia since 2003 is the organizer of one of the biggest music festivals in Europe. City count about 244 000 inhabitants and the festival in 2015 appeared about 120 000 people. Arrange transport for such a large number of people is a huge problem for city authorities and organizers. Changes in traffic conditions and freedom of movement around the city are cumbersome for inhabitants of the city. Gdynia has access to the maritime port; freight transport is an inherent image of the city. The city has a specific location of the infrastructure, in the centre of the city is a port. Port is divided city into northern and southern part. Residents of the north can only use the road infrastructure to get to the south and to the city centre. The city provides festival participants with free access to the festival area by city buses. This article presents the loss of time generated by increased traffic on the road during festival days. The reliability of the urban network laden by the traffic of passenger vehicles, trucks to the port as well as special festival buses is based on calculations of the mathematical model. The data on which the model was developed come from TRISTAR's (Tricity's Intelligent Transportation System) - the vehicle counting system and traffic metering station. This System allows to count the time of each vehicle which has been detected by the induction loop and thus the time intervals between vehicles. The data are compared with the festival days and typical days of operation in the transport network.
