Proposal of traffic calming guidelines

Prehitro in nevarno vožnjo na cestah je treba ponekod umirjati z napravami in ukrepi za umirjanje prometa. Njihov primarni namen je omogočiti dobre življenjske pogoje z izboljšanjem varnosti, mobilnosti in udobja nemotoriziranega prometa, kar pa dosežemo z znižanjem hitrosti vozil in prometnih obremenitev na cestah. V magistrski nalogi sem naredila pregled slovenske tehnične specifikacije za umirjanje prometa TSC 03.800: 2009 Naprave in ukrepi za umirjanje prometa in rešitve, ki se uporabljajo v tujini. Ugotavljala sem ustreznost ukrepov na različnih kategorijah cest in njihovo učinkovitost pri znižanju hitrosti vozil, pretoka, hrupa in emisij ter zagotavljanja varnosti lažje ranljivih udeležencev v prometu. Podatke sem uredila v tabeli. Pregledala sem primere dobre prakse iz tujine in njihovo uporabo, nekaj izbranih sem idejno umestila v naše okolje in jih opisala – speed kidney (otoki za umirjanje), speed cushion (hitrostna grbina), road-diet (preureditev voznega pasu za namene pešcev in kolesarjev) in odstranitev sredinske črte. Na odseku Cankarjeve ulice v Črnomlju (LZ 054171), na mestu prehoda za pešce, sem na praktičnem primeru prikazala izvedbo dvostranske zožitve vozišča z izmeničnim enostranskim prometom (varianta A) in postavitev hitrostne naprave za umirjanje prometa speed kidney, ki se uporablja ponekod v tujini (varianta B).In some places, speeding and reckless driving on the roads sometimes needs to be moderated with traffic-calming devices and measures. Their primary purpose is to support good living conditions in residential and commercial areas by improving the safety, mobility, and comfort of non-motorized traffic participants. Latter is achieved by reducing vehicle speeds and volumes on streets or street networks. In the master\u27s thesis, I reviewed the Slovenian technical specifications for traffic calming TSC 03.800: 2009 Traffic calming devices and measures, and measures and solutions used abroad. I determined the appropriate measures on different categories of roads and their effectiveness in reducing vehicle speed, volume, noise, emissions and ensuring the safety of more vulnerable participants in traffic. For better clarity, I prepared an overview table with this information. I reviewed examples of traffic calming from abroad and suggested the use of a few in our country – speed kidneys (traffic calming islands), speed cushions, road-diets (lane reduction), and centreline removals. In a practical example, I demonstrated traffic calming at the pedestrian crossing on a section of a local road Cankarjeva ulica (LZ 054171) in Črnomelj. Two variants were proposed – two-sided narrowing of the carriageway with alternating one-way traffic (variant A) and the installation of a speed kidney (variant B)
