Roundabout capacity with incorporating of exiting flow |
Sekundarni povzetek: |
Analysing roundabouts’ traffic flow and calculation of their entry lanes’ capacity has been a subject of research of several authors in the last decades. The majority of methods focus on empirical and stochastic models which differ in a definition of the conflict flow. No gap
acceptance model in the literature takes the exiting traffic flow into account when estimating capacity – all methods are based on merging of circulating flow (on the roundabout passing entry lane) only.
The proposed PTI method is based on the models developed using the gap acceptance and queuing theory. It extends the most widely used Brilon model by considering both, the
circulating and the exiting flow.
The proposed PTI method was tested on a simple roundabout entry with one entry, exit and circulating lane. The roundabout entry capacity and the average delay per vehicle were calculated using the PTI method and Brilon and Bovy model. The average driver’s delay for all analytical models is calculated by the same delay equation. The results were compared to the quasi observed data. Sources of the quasi observed data were compared with the results of the microscopic simulation using VISSIM software.
In the second part of the thesis; the two-lane classic and turbo roundabout capacity was determined for different traffic flows with Brilon's model and PTI method. The purpose of the comparison is to show the impact of the exiting flow in the classic roundabout compared to the turbo roundabout. |
