Abstract EN
This paper investigates roundabout capacity analysis using mathematical modelling and microscopic simulation.
The capacity in approach section in roundabout is calculated by estimating the number of vehicles that can enter a roundabout for a given approach given a certain circulating volume.
Since roundabouts are working with only yield conditions, capacity is dependent on gap acceptance model.
Priority rules are used to simulate the gap acceptance model and define the right-of-way for conflicting movements.
In the case of roundabouts, priority rules can be utilized to establish right-of-way at each of the conflict points where the approach traffic merges with the circulating traffic of the roundabout.
By altering the minimum acceptable gap and related parameters, it is possible to calibrate a simulation model to be that of a real-life roundabout or that of a theoretical roundabout that meets the operating characteristics defined in current capacity models.
The proposed roundabout capacity analysis methodology is expected to assist modelling operational conditions for roundabouts.
Results are presented that provide evidence to validate the proposed approach.
