Analysis of Traffic Signs Standardization in the European Union
No full textPrometna signalizacija služi za vođenje i sigurno odvijanje prometa. Prometnom korisniku prenosi obavijest o trenutačnom ili budućem stanju prometnoga sustava, brzini kretanja i položaju korisnika u sustavu, preporučenom i obveznom načinu kretanja i dr. U prometnu signalizaciju kao podskup te cjeline ubrajaju se prometni znakovi, tj. taj cijeli skup sa svim prometnim znakovima bez kojeg bi promet djelovao nezamislivo. U većini država Europske Unije ti prometni znakovi su u većini standardizirani s ciljem što bržeg i jednostavnijeg prepoznavanja značenja poruke koju prenose. Od samih začetaka prometa očituje se i provodi standardizacija prometnih znakova, a prva suvremena standardizacija definirana je potpisivanjem ugovora u Beču 1968. godine pod nazivom Bečka konvencija o cestovnim znakovima i signalima. Cilj ovog rada je analizirati i odrediti razinu standardiziranosti prometnih znakova u državama Europske Unije. Analizu provesti na razini podskupina prometnih znakova te također, provesti usporedbu današnjih prometnih znakova sa onima definiranim Bečkom konvencijom.Traffic signalling is used for guiding and safe operation of traffic. It shall transmit to the traffic user the notification of the current or future state of the transport system, the speed of movement and the position of the user in the system, the recommended and mandatory mode of movement, etc. Traffic signals as a subset of this whole include traffic signs, that is, this whole assembly with all traffic signs without which traffic would seem unimaginable. In most EU countries these traffic signs are standardised in most standardized with the aim of recognising as quickly and easily as possible the meaning of the message they convey. Since the very beginning of traffic, the standardisation of traffic signs has been manifested and implemented, and the first contemporary standardization was defined by the signing of the contract in Vienna in 1968 under the name of the Vienna Convention on Road signs and signals. The aim of this paper is to analyse and determine the level of standardised traffic signs in EU countries. Perform an analysis at the level of subsets of traffic signs and also compare contemporary traffic signs with those defined by the Vienna Convention

No full textU radu je provedena simulacijska analiza željezničkog prometa na pruzi M103 Dugo Selo – Novska. Nakon napravljenog simulacijskog modela postojećeg stanja moguće je izračunati iskorištenje kapaciteta pruge po UIC metodi 406, te izračunati propusnu moć pruge (metoda 405). Navedeno je izračunato i za pružnu dionicu nakon modernizacije i izgradnje dodatnog kolosijeka. Povećanjem maksimalne brzine na pruzi, kolodvor Ivanić Grad moguće je uvesti u prigradski promet grada Zagreba, stoga je implementiran novi taktni vozni red. Izradom simulacijskog modela novog stanja pruge, moguće je napraviti usporednu analizu starog i novog stanja. Usporedna analiza se sastoji od vremena putovanja, komercijalne brzine i potrošnje energije.The simulation analysis of railway traffic on line M103 Dugo Selo – Novska has been conducted in this thesis. After the initial state of the railway was modelled, it was possible to calculate capacity usage using UIC method 406 and headway time using method 405. The calculation was also made for railway line after modernisation and construction additional track. Increasing the maximum track speed, Ivanić Grad station was able to join the commuter traffic network in Zagreb. For that to happen, it was necessary to implement a cyclic timetable. After the new and improved state of railway infrastructure was modelled it was possible to create a comparative analysis of the two states of infrastructure. A comparative analysis was conducted using travel time, operative speed and energy usage
