Speed reduction effects of urban roundabouts

Wind Speed Reduction Induced by Urban Morphology

Accurate prediction of advection and turbulent mixing is fundamental to understanding the transport and deposition of atmospheric pollutants. There is mounting evidence hinting at overestimation of wind speed in the urban airshed by conventional mesoscale NWP models. This has been hypothesized as a factor contributing to air quality models underestimating pollutant concentrations in highly urba...

Modelling Traffic Flow at Multi-lane Urban Roundabouts

This paper proposes Multi-stream Minimum Acceptable Space (MMAS) Cellular Automata (CA) models to study unsignalised multi-lane (twoor three-lane) urban roundabouts. Through detailed space considerations, using Cellular Automata (CA) and the Multi-stream Minimum Acceptable Space method, heterogeneity and inconsistency of driver behavior and interactions in cross traffic at entrances of roundabo...

Capacity-Related Driver Behavior on Modern Roundabouts Built on High-Speed Roads

Ahmad, Shaikh.M.S.C.E.,Purdue University, December 2014.Capacity-Related Driver Behavior on Modern Roundabouts Built on High-Speed Roads. Major Professor: Andrew Tarko. The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of driver...
