Raziskava povezave med hidroplaningom in nezgodami na mestih zastajanja padavinske vode na voziščih zaradi vijačenjaPodgoršek, MihaProblematika vijačenja na avtocestah je v Sloveniji že dobro poznana, saj ji je bilo v preteklih letih posvečenega veliko truda, znanja in energije. Ukrepi so se izvajali samo na avtocestah in hitrih ... cestah, ostale državne cestepa so bile zanemarjene. Zato je ta referat orientiran na državno cestno omrežje v pristojnosti Direkcije Republike Slovenije za ceste (DRSC), ki obsega nekaj manj kot 6.000 km cest različnih kategorij. Na državnih cestah (DRSC) se nahaja približno 28.000 vijačenj. Vsa vijačenja so potencialna mesta nastanka pojava hidroplaninga, še posebej nevarna pa so vijačenja pri minimalnih vzdolžnih nagibih (med -1 % in +1 %), kjer prihaja do zastajanja vode že pri nizki intenziteti padavin. Najbolj kritični so široki cestni odseki, kjer je možno razviti vsaj 90 km/h, kar velja za spodnjo mejo nastanka hidroplaninga. Takih območij je približno 7.000. Ob upoštevanju vseh zgoraj omenjenih pogojev je bila izvedena analiza nezgod v obdobju 2000-2005 na območjih vijačenj in celotnih odsekih na suhem in mokrem vozišču. Analiza je pokazala, da je na mokrem vozišču na območjih vijačenj za 16 % več nezgod na enoto dolžine kot na celotnih odsekih. Vzrok za to povečanje gre zagotovo iskati tudi v pojavu hidroplaninga.Source: Zbornik referatov (str. 259-267)Type of material - conference contribution ; adult, seriousPublish date - 2006Language - slovenianCOBISS.SI-ID - 618078
