Znaczenie komponentów dostępności transportowej w Szczecinie w latach 2009-2018 = Significance of transport acces-sibility components in Szczecin in the period 2009-2018

Abstract

This monograph deals with the importance of the components of transport accessibility in the city of Szczecin, north-western Poland, over the period 2009-2018, with particular attention to public transport. The study uses census districts to look at the accessibility of a range of destinations by both public and private (car) means of transport in 2018 and adds three other years, 2009, 2012 and 2015, for public transport alone. The empirical part of the study involved statistical methods and specific points in time in 2018, including date, hour and minute. The specific metrics used for the static data about each destination included: shortest distance, percentage of the population, cumulative accessibility, potential accessibility, potential quotient, and for the final outcome, a synthetic ranking metric with data standardisation. The dynamic part of the empirical research covers the entire study period, i.e. 2009-2018, supplemented by data on single days running from 5:00am to 10:00 pm. For the longer of the periods, the method of potential accessibility to population was used. The choice of methodology involved a review of various GIS tools and their applicability to city-wide accessibility research, including text format data (GTFS) covering several years. Each of the research methods employed was assessed for its impact on the individual components of transport.
