Abstract
Pravovremena i odgovarajuća ocjena stanja kolosijeka glavna je stavka upravljanja nekim tračničkim sustavom, bilo to tramvajski ili željeznički sustav. Ocjena stanja kolosijeka ogleda se na uočavanju odstupanja i nepravilnosti u geometriji kolosijeka, kao i na ocjeni udobnosti vožnje. Ovim radom prikazan je „inovativni" pristup ocjeni stanja tramvajskog kolosijeka na dionicama tramvajskog sustava grada Zagreba, prikupljenih iz tramvaja u regularnom prometu. Primarni cilj ovog istraživanja je iskoristiti mogućnosti pametnih telefona i njihovih ugrađenih senzora, kao što su akcelerometar i žiroskop, za prikupljanje informacija o geometriji i stanju kolosijeka. Prikupljanje podataka vršeno je na dvije dionice tramvajskog sustava, koristeći senzore dvaju pametnih telefona marke Samsung i sofisticiranijeg akcelerometara postavljenih unutar tramvaja, te mjerenjem geometrije ručnim kolicima TEC-1000. Analiza geometrije provedena je usporedbom vibracija i podataka žiroskopa zabilježenih pametnim telefonima sa podacima bilježenim standardnim mjerenjem geometrije kolosijeka, uz pozicioniranje preko zabilježenih GPS podataka. Prikupljeni podaci iskorišteni su i provedbu ocjene udobnosti vožnje. Unatoč nedostacima i izazova ovakvog pristupa prikupljanju podataka, dobiveni rezultati i zapažanja imaju potencijal poboljšati održivost i performanse tramvajske infrastrukture u urbanim sredinama.
Abstract (english)
Timely and appropriate assessment of track conditions is a crucial aspect of managing any rail system, whether it's a tram or railway system. Evaluating track conditions involves identifying deviations and irregularities in track geometry, as well as assessing ride comfort. This paper presents an innovative approach to assessing the state of the tram track along sections of Zagreb's tram system, gathered from tram in regular operation. The primary aim of this research is to leverage the ubiquity of smartphones and their built-in sensors, such as the accelerometer and gyroscope, to collect information about track geometry and its condition. Data collection was carried out on two sections of the tram system, utilizing sensors from two Samsung smartphone and a more sophisticated accelerometer placed within the tram, along with manual measurement of geometry using the TEC-1000 trolley. Geometry analysis involved comparing vibrations and gyroscope data recorded by smartphones with data obtained from standard track geometry measurements, using positioning via recorded GPS data. The collected data was also utilized to assess ride comfort. Despite the challenges encountered during this research, the obtained results and observations have the potential to enhance the sustainability and performance of tram infrastructure in urban environments.
