magistrsko delo
Abstract
V magistrskem delu je obravnavano dvopasovno krožišče na mengeški obvoznici ter predlog rekonstrukcije v turbo krožišče. Izvedena je analiza kapacitetnih parametrov obeh s programskim orodjem SIDRA INTERSECTION in analitično z uporabo Bovyjeve enačbe. Dodatno je izdelan simulacijski model za obe rešitvi in simulacije za merodajno jutranjo prometno koncu na koncu planske dobe leta 2038. Poleg kapacitetnih parametrov smo kot rezultat simulacije dobili tudi trajektorije vozil, ki smo jih uporabili kot vhodni podatek za modelsko analizo konfliktnih točk. Analiza prometne varnosti dvopasovnega in turbo krožišča pokaže, da je prometno varnejše turbo krožišče. Na podlagi kapacitetne analize, prometno varnostne analize in kriterijev upravičenosti, lahko zaključimo, da je turbo krožišče na tem mestu primernejša rešitev od klasičnega dvopasovnega krožišča.

Secondary title: |
Proposal for the reconstruction of a two-lane roundabout with capacity and traffic-safety analysis |
Secondary abstract: |
Roundabout is a type of circular intersection in which road traffic flows in an anti-clockwise direction. They were developed as an alternative to classic intersection and have many adventages. From those stands out improvement of road safety because number of possible collision points compared to classic intersection is reduced by more than half. The two-lane roundabout have two circular lanes, but with that capacity doesn't duplicate but new possible collision points and conflicts areas are created. Today, two-lane roundabout are performed only exceptionally when a turbo roundabout can't be performed. A turbo roundabout is a roundabout with spiral course of circular lanes separated by a raised lane separator. In this master thesis is discussed two-lane roundabout on the bypass road of Mengeš and a proposal of reconstruction into turbo roundabout. An analysis of the capacity parameters were performed with SIDRA INTERSECTION and analytically using Bovy model. In addition, a simulation model was developed for both solutions and simulations for the relevant morning traffic peak at the end of the planning period in 2038. As a result of the simulation, we also received vehicle trajectories that were used as inputs for the model analysis of conflict points. The traffic safety analysis of the two-lane and turbo roundabout shows that turbo roundabout has less possible collision points. On the basis of capacity analysis, traffic safety analysis and eligibility criteria, we can conclude that the turbo roundabout at this site is a more suitable solution than a conventional two-lane roundabout. |
