20.500.12556/RUL-137828 Roundabout capacity estimation model considering driver behaviour on the exiting and entry flows Model za oceno prepustnosti krožišč z upoštevanjem obnašanja voznikov pri vhodu in izhodu iz krožišča Roundabout capacity estimation has been the subject of several types of research in recent decades. Most of the analyses are based on the empirical or analytical models (e.g. gap acceptance theory) considering various kinds of conflicting flows, namely entry, circulating, and exiting flow. The drivers on the exiting flow either obey the traffic rule (use the right-turn indicator) or disobey the traffic rule (do not use the right-turn indicator). According to the reviewed literature, the impact of these drivers on the roundabout capacity has not been studied to a greater extent. Therefore, this study aims to develop an analytical roundabout capacity estimation model that also takes into account a share of exiting flow. It extends Brilon-Wu’s model, by including the impact of exiting drivers who disobey the traffic rule on the gap acceptance of the entering drivers. The proposed model was validated using the quasi-observation data generated by a microscopic model. The results obtained by our model were compared with Bovy’ and Yaps’ empirical models as well as Brilon-Wu’s analytical model for a single-lane roundabout. Using the RMSE and regression analysis, it is proved that the proposed model outperforms the existing models in terms of estimating the capacity and delays of roundabouts. Ocena prepustnosti krožišč je bila tema vrste raziskav v zadnjih desetletjih. Večina analiz bazira na empiričnih ali analitičnih modelih (npr. teorija sprejemljivih vrzeli), pri čemer upošteva različne vrste konfliktnih tokov (vhodni, krožni in izhodni tokovi). Vozniki na izvozu lahko upoštevajo ali pa ne upoštevajo pravila obvezne uporabe desnega smernega kazalca. Glede na pregledano literaturo vpliv voznikov, ki ne upoštevajo tega pravila, na prepustnost krožišča, ni dobro raziskan. Zato smo se odločili razviti analitični model, ki upošteva tudi del izvoznega prometnega toka. Ta model nadgrajuje model Brilon-Wu. Predlagani model je bil preverjen z uporabo “kvazi” opazovanih podatkov, ki so bili generirani z uporabo mikroskopskih simulacij. Rezultate smo primerjali z rezultati empiričnih modelov Bovy in Yap ter z analitičnim modelom Brilon-Wu za enopasovna krožišča. Z uporabo RMSE in regresijske analize smo dokazali, da predlagani model daje boljše rezultate kot do sedaj uporabljani modeli. roundabout capacity driving behaviour entry flow exiting flow gap acceptance theory krožišče prepustnost obnašanje voznikov vhodni tok izvozni tok teorija sprejemljivih vrzeli true false true Angleški jezik Slovenski jezik Podatek o licenci CC BY 4.0 je naveden na pristajalni strani članka – glej izvorni URL zgoraj.
