Abstract

Reguliranje prometa na izvangradskim dionicama cesta svodi se u najvećoj mjeri na reguliranje režima brzina i pretjecanja. Na dvotračnim cestama pretjecanje predstavlja jednu od najsloženijih radnji iz razloga što vozilo koje pretječe određen period vremena boravi na prometnoj traci koja je namijenjena za kretanje vozila iz suprotnog smjera. U realnom prometnom toku pretjecanje se javlja zbog heterogene strukture prometnog toka, različitih voznodinamičkih sposobnosti vozila i različitih karakteristika vozača i njihovog ponašanja. Iz tog razloga na svim izvangradskim dionicama cesta neophodno je omogućiti određen broj dionica i odsjeka na kojima je pretjecanje dopušteno. Dionice i odsjeci na kojima je pretjecanje dopušteno, zovu se zone dopuštenog pretjecanja. Obveza projektanata je da prilikom projektiranja cesta omoguće zone dopuštenog pretjecanja koje na dvotračnim (npr. magistralnim) cestama trebaju biti zastupljene na najmanje 20% dužine ceste. Zone dopuštenog pretjecanja formiraju se na temelju potrebne dužine pretjecajne preglednosti. Preglednost pri pretjecanju (Pp) je razmak koji vozilo prijeđe za vrijeme opažanja situacije (vrijeme reakcije), povećanja brzine, pretjecanja i vraćanja na svoju prometnu traku. Preglednost pretjecanja definira se i kao minimalno omogućen razmak na kojem vozač vozila koji namjerava preteći sporo vozilo ispred sebe može uočiti vozilo koje dolazi iz suprotnog smjera. Omogućivanje potrebne dužine pretjecajne preglednosti veoma je važno zbog postizanja razine usluge i sigurnosti prometa na cestama.

Abstract (english)

The regulation of traffic on out-of-town sections of the roads is mostl focused on the regulation of the speed and passing regime. On two-lane roads, passing is one of the most compex actions due to the fact that the vehicle that pass stays a certain period of time on the traffic lane intended for the movement of vehicles from the opposite direction. In real traffic flow, passing occurs due to the heterogeneous structure of traffic flow, different driving dynamics of vehicles and different characteristics of drivers and their behaviour. For this reason, it is necessary to enable a certain number of sections where passing is allowed are called passing zones. The obligation of designers is to enable passing zones when tracing and designing roads, which should be represented on at least 20% of the road length on two-lane roads. Passing zones are formed on the basis of the required length of passing visibility. Passing visibilty is the distance traveled by the vehicle during the situation observation (reaction time), speed increase, passing and return to its traffic lane. Passing visibilty is also defined as the minimum allowable distance at which the driver of a vehicle intending to pass a slow vehicle in front of him can spot an oncoming vehicle from the opposite direction. Providing the required length of oversight is very important in order to achieve the level of service and road safety.
