20.500.12556/RUL-126430 Decelerations of passenger vehicles on gravel arrester beds Gravel-filled arrester beds, also called safety-escape ramps or vehicle run-out areas, have long been a road-safety feature for safely stopping heavy road vehicles from running off the road. In the recent past, there has been consideration given to installing these features on highway access ramps to provide safe areas to stop passenger cars driving at highway speeds. The work presented in this article was performed to investigate the behaviour of standard-size passenger cars on gravelfilled arrester beds, with a particular focus on the achievable vehicle decelerations and the ability of the arrester beds to safely stop a passenger car coasting in an uncontrolled manner. The findings show that the achievable average decelerations are in the range of 0.3 g for coasting vehicles and up to 0.9 g when the vehicles are braking. The results prove that more research is required to quantify the influence of the gravel parameters on the achievable decelerations. gravel arrester bed escape ramp run-out area deceleration traffic safety measurement prod ustavljalna površina izletna rampa izletna cona pojemek prometna varnost meritev true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-21 21:03:51 2021-04-21 21:03:55 2023-11-29 10:54:35 0000-00-00 00:00:00 2020 0 0 13 str. iss. 5, art. 1761 Vol. 12 Mar. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 614.8(045) 2071-1050 10.3390/su12051761 17057051 RAZ_Trajkovski_Jovan_2020.pdf RAZ_Trajkovski_Jovan_2020.pdf 1 320D03D87D2CFEB948CDC5CE5A807584 413fee7dfde1ffd5d796abe6098f6bc87a09ea5d911484c25930e99e5b1bc7c3 f132d297-a2d5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142389 RAZ_Trajkovski_Jovan_2020.zip RAZ_Trajkovski_Jovan_2020.zip 1 275ABC59B20D43CA210504039402098B 9eea65669859061be91caef2fd07cb3f53f404ccd6d6abd529c760fc21671db4 ff439b5a-a2d5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142390 https://www.mdpi.com/2071-1050/12/5/1761 1 51f060ad-a2d4-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142388 Fakulteta za strojništvo 0 0 0
