Analysis of the Accessibility of Prague in Czechia in the 1918 – 2020 Period

Abstract

The article deals with accessibility development in Czechia since the setting up of Czechoslovakia in 1918 till the year of planned completion of the main motorways and train corridors in 2020. One hundred years is a sufficiently long period to understand many of geographical processes related to accessibility patterns.The main goal is to digitalize transport networks for every ten years (dates of Census) and build accessibility models with average speeds, times for changing between trains and waiting times on stations, etc.The project is also focused on calculating the accessibility of Prague making isochrone maps and deals with a thematic cartography method -radial anamorphosis -as an ideal method for visualization of isochrone surfaces. The results will show the exact time period from which road transportation overtook trains in time accessibility or vice versa. Even though accessibility is investigated in relation to the capital of the Czech Republic, the methodology could be used for any other place in the country.Key words: accessibility, transport, GIS, Prag, historical development Analiza dostupnosti Praga u Republici Češkoj od 1918. do 2020.Rad se bavi razvojem prometne dostupnosti u Češkoj Republici od osnutka Čeho-slovačke do planiranog završetka glavnih cestovnih i željezničkih koridora 2020. Stotinu godina dovoljno je dugo razdoblje kako bi se moglo razumjeti geografske procese povezane s obrascima dostupnosti.Glavni je cilj rada digitalizacija prometnih mreža za svako međupopisno razdoblje (deset godina) i stvaranje modela dostupnosti s prosječnom brzinom, vremenom presjedanja, vremenom čekanja na stanicama itd.U radu se također nastoji dati precizan izračun dostupnosti Praga pomoću karata s izokronama te se primjenjuje metoda tematske kartografije -radijana anamorfoza -kao idealna metoda vizualizacije izokronih površina. Rezultati će pokazati točna razdoblja u kojima je cestovni transport brži od željezničkoga i obrnuto. Iako je istraživanje dostupnosti u ovom radu usmjereno na glavni grad Češke Republike, upotrijebljeni model može se primijeniti na bilo koje naselje u državi.

Transport Accessibility As a Factor of Depopulation and Developmental Delay: Case Study Žumberak

“…6 Analiza je izvršena u alatu QGIS 2.6. O mogućnostima primjene GIS-a u analizi prometne mreže vidjeti Bitters (2009);Hudeček (2011);Fransen i sur. (2015).…”

Saving Travel Time as an Urban Planning Instrument. Case Study: Manizales, Colombia

“…It analyzes road infrastructure performance or service, measuring traffic or average speed in the network, obtained as the average of average travel times of all the nodes in a transport infrastructure network (Escobar & García, 2012). Researchers have used these different approaches to accessibility in order to study it in relation to: sustainable development of transport (Vega, 2011), transportation planning (Talpur, Napiah, Chandio, & Khahro, 2012), urban public transport (Curtis & Scheurer, 2015), development of new transport infrastructures (Karou & Hull, 2014;Escobar & García, 2011;Escobar & García, 2012), social equity (Grengs, 2014;Guzmán, Oviedo & Rivera, 2017), road redirection (Escobar, Duque & Salas, 2015), temporary analysis of the change in territorial accessibility (Hudeček, 2011), comparison with urban growth (Shoorcheh, Varesi, Mohammadi, & Litman, 2016), among others. This research analyzes accessibility based on infrastructure, considering the impact that an alternative road infrastructure generates on the city in terms of average travel times.…”
