Abstract

Organizaciju prijevoza putnika u željezničkom prometu definiraju tehnološka rješenja ovisna o optimizaciji iskorištenja infrastrukture. Izradeni model temelji se na promjenjivim vremenskim komponentama minimalnog intervala slijeclenja i klasifikaciji vlakova prema vremenskim karakteristikama putovanja, što dovodi do povećanja iskorištenja infrastrukture. Istraživanja optimizacije željezničke mreže i putničkog prometa te taktnog voznog reda temelje se na prediktivnim metodama i matematičkim alatima za modeliranje i simulaciju sustava. Određivanje minimalnog intervala slijedenja te rezervnog i dodatnog vremena spada u optimizaciju iskorištenja infrastrukture. Optimizacijom navedenih vremena osigurava se stabilnost i kvaliteta voznog reda čime se utječe na razinu usluge i karakteristike prometno-tehničkih i operativnih svojstava mreže. Za modeliranje putničkog prometa i određivanje granica izmedu pojedinih vrsta putničkog prometa umjesto fiksne geografske pozicije koriste se definirani vremenski intervali putovanja. Takav pristup obvezuje upravitelja infrastrukture da povećanjem kvalitete infrastrukture omoguči veće maksimalne brzine na pruzi. Povećanjem brzine uzročno-posljedično se povećava radijus odredenog područja prometa, prije svega gradsko-prigradskog prometa. Definiranjem tehnoloških postupaka u organizaciji prometa temeljenih na vremenskim komponentama i smjernicama razvoja gradsko-prigradskog prometa povećava se iskorištenje infrastrukture i prijevoznih sredstava te kvaliteta usluge. Za modeliranje i simuliranje prometnog modela temeljenog na vremenskim parametrima koristit će se teorija diskretnih događaja i matematički pristup koji koristi Petrijeve mreže.

Abstract (english)

The organization of passenger traffic in railway transport is defined by technological solutions dependent on the optimization of infrastructure utilization. The development of a model based on the variable time components of the minimum tracking interval and the classification of trains according to the time characteristics of the journey as a result optimize the utilization of infrastructure. Research on the optimization of the railway network and passenger traffic and the schedule is based on predictive methods and mathematical tools for modeling and simulation of the system. Determining the minimum follow-up interval and reserve and spare time is part of optimizing infrastructure utilization. The optimization of these times ensures the stability and quality of the schedule which affects the level of service and the characteristics of traffic-technical and operational properties of the network. Travel modeling is used instead of a stable geographical position to model passenger traffic and determine boundaries between separate types of passenger traffic. Such an approach obliges the infrastructure manager to enable a higher maximum speed on the line by increasing the quality of infrastructure. Increasing the speed causally increases the radius of a certain area of traffic, primarily urban-suburban traffic. Defining technological procedures for the organization of transport based on time components and guidelines for developing urban-suburban transport increases the use of infrastructure and means of transport as well as the quality of service. Discrete event theory and the mathematical approach used by Petri Nets will be used to model and simulate a traffic model based on time parameters.
