Modeliranje uticaja režima saobraćajnog toka na elemente rada vozila javnog prevoza

Abstract

Promena parametara saobraćajnog toka utiče na promenu elemenata rada vozila JGPP-a, kada ona saobraćaju u mešovitom saobraćajnom toku. Elementi rada vozila JGPP-a su definisani redom vožnje pa svako odstupanje od planiranih elemenata rada izaziva određene poremećaje u radu vozila na linijama kao i u celokupnom sistemu JGPP-a. Po pravilu, svaki poremećaj u radu vozila JGPP-a negativno se odražava na kvalitet usluga koje se pružaju korisnicima. U okviru ovog rada, izvršena je analiza uticaja karakteristika saobraćajnog toka na elemente rada vozila JGPP-a. Na osnovu analitičko–istraživačkog postupka razvijen je model zavisnosti vremena putovanja vozila JGPP-a od saobraćajnog opterećenja, na gradskoj uličnoj mreži. Razvijeni model testiran je na realnim podacima dobijenim istraživanjima na području Novog Sada. Utvrđene su međusobne zavisnosti veličine saobraćajnog toka i vremena putovanja, a indirektno, preko vremena putovanja određene su i zavisnosti ostalih elemenata rada vozila JGPP-a od promene veličine saobraćajnog toka. Poznavanjem zakonitosti promene ispitivanih parametara, moguće je projektovati elemente rada vozila JGPP-a u skladu sa realnim stanjem saobraćajnog toka i na taj način uticati na poboljšanje funkcionisanja sistema JGPP-a, a samim tim i na povećanje kvaliteta usluge koji se pruža korisnicima.

Change of the traffic flow parameters cause the change of the function elements of public transport vehicles, when it operate in mixed traffic flow. Function elements of the public transport vehicles are defined by schedule, so that any deviation from the planned function elements cause some disorder in the entire public transport system. As a rule, any disorder in operation of public transport vehicles has negative impact on the quality of service provided to users. In this paper, the influence of traffic flow characteristics on the function elements of public transport vehicles has been analysed. The model depending travel time of public transport vehicles from traffic volume on the city’s street network, based on the analytical research process, has been developed. The developed model was tested on real data obtained by research in the area of Novi Sad. Interaction of the volume and travel time has been determined and indirectly, through the travel time to the dependence of other function elements of public transport vehicles of traffic flow has been determined. Through knowledge of regularity of change of the parameters, it is possible to design function elements of the public transport vehicles in accordance with the real situation of the traffic flow and thus affect the improvement of operating of public transport system with increase the quality of service for users.
