Urban arterials in developing countries accommodate highly heterogeneous, non-lane-based traffic streams whose lateral dynamics remain poorly characterised. This study analyses the spatial distribution and lateral interaction of main vehicle classes on a four-lane undivided arterial in Sri Lanka using high-resolution t...

This research develops an adaptive traffic signal control scheme to address heterogeneous traffic conditions prevalent in developing nations, where poor lane discipline and frequent lane changes limit the effectiveness of traditional adaptive signal control schemes based on static Passenger Car Unit (PCU) values. Dynam...

SUMO (Simulation of Urban MObility) provides considerable capability for traffic studies in developing countries. However, by default it is calibrated for lane-disciplined, homogeneous traffic of Europe. This study developed an aggregate level calibration strategy to make SUMO suitable for heterogeneous traffic in sign...

This study analyses 397,850 police-reported crashes in Sri Lanka from 2010 to 2020 using a multinomial logit model, validated through Random Forest and XGBoost, to identify key factors influencing crash severity across four outcome levels. Results reveal four findings not apparent from conventional crash statistics. Fi...
