Arathi, A.R.Harikrishna, M.Mohan, M.2026-02-042023International Journal of Intelligent Transportation Systems Research, 2023, 21, 2, pp. 349-36013488503https://doi.org/10.1007/s13177-023-00360-6https://idr.nitk.ac.in/handle/123456789/21793This study has developed simulation-based models for evaluating the performance of skewed uncontrolled intersections since the existing models do not consider the effect of skew angle. The calibration parameters for simulating four-legged uncontrolled intersections are suggested. The results indicate that the developed simulation model can predict the capacity and level of service more accurately than the existing Indo-HCM. Moreover, different scenarios were also analysed to study the influence of speed breaker, temporary median, widening, and change in vehicle proportions on capacity. The study also proposes skew-angle-based volume warrants for the capacity of approach roads, which will be helpful for design engineers. © 2023, The Author(s), under exclusive licence to Intelligent Transportation Systems Japan.Intelligent systemsCalibration parametersCapacityLevel of ServiceMicrosimulationPerformancePerformances evaluationSimulation-based modelsSkew anglesUncontroled intersectionVolume warrantCalibration
