Vol. 28, nr 1

63-66

Purpose: The building of mathematic model, which enable description of urban public transport network is a purpose of the article. This model will make the estimation of public transport quality according to analysis of punctuality easier. Design/methodology/approach: The methodology of building the mathematical model of public transport network consists in application of the graph theory. The mathematical instruments make the description of real network easier. Findings: The mathematical model of public transport network on the proper level of aggregation may be effective instrument, which assists the decision process. It makes an estimation of chosen coefficients that describe public transport quality easier. Research limitations/implications: The research has been conducted only in the range of punctuality estimation for the sake of time-consuming and expenses. This limit also concerns database. It requires detailed description of public transport network to exact presentation in mathematic model. Originality/value: To make the calculations more efficient, the relative database has been built. It includes geometric parameters of the sections and junctions in network. It also covers all necessary detailed data of analysed public transport lines. The database is the ground for estimating punctuality in research area.
