Safety evaluation of urban roundabouts in India: a safety performance function-based approach
Traffic Safety Research, 2022 There is a lack of comprehensive research in roundabout safety under non-lane-based traffic conditions, mainly due to the absence of relevant crash data and effective tools for safety evaluation.

Modeling of Effective Parameters for Capacity Prediction at Signalized Intersection Lanes
The Baltic Journal of Road and Bridge Engineering, 2022 Current capacity manuals do not allow comprehensively evaluating negative effects on lane capacity caused by undisciplined vehicle movements and lane utilization, such as failure to obey distance rules, lane blockage caused by roadside parking effect ...

Capacity evaluation of multi-lane traffic roundabout [PDF]
, 2009 The entry capacity at a traffic roundabout is typically evaluated for each entry approach, considering the circulating flow and geometric characteristics, e.g., the US highway capacity manual model and the UK Linear Regression model. These models are not
