Comparison of selected capacity calculations for roundabouts
Original language description
The paper deals with comparison of selected capacity calculations for roundabouts used in the Czech Republic. Some traffic engineers use the qualitative methods based on Germany methodology HBS, but some ones still use the quantitative methods for capacity assessment of roundabouts. The quantitative methods are based on the traffic volumes on entries and circulatory roadway of roundabout and they usually use an array of coefficients which represent next roundabout parameters. The qualitative methods are also based on the traffic volumes on entries and circulatory roadway of roundabout and they minutely deal with numbers of traffic lanes, time spaces and mainly average delay times (e.g. critical gap and follow-time) and level of service for entries. The method used in the Czech Republic also deals with the capacity of the exits, including influence of pedestrians on pedestrian crossings and volume/capacity ratio for exits. Attention is also paid to the other types of roundabouts, i.e. not only single-lane and double-lane roundabouts, but also mini and turbo roundabouts. This paper presents the results of calculations by both types of methods for various types of roundabouts and shows the differences used methods.
