Transport Phenomena in the Urban Street Canyon
1 Abstract A generic proecological traffic control model for the urban street canyon is proposed by development of advanced continuum field hydrodynamical control model of the street canyon. The model of optimal control of street canyon dynamics is also investigated. The mathematical physics' approach (Eulerian approach) to vehicular movement, to pollutants' emission, and to pollutants' dynamic...
متن کاملCFD modeling of pollution dispersion in a street canyon: Comparison between LES and RANS
CFD modeling using RANS and LES of pollutant dispersion in a three-dimensional street canyon is investigated by comparison with measurements. The purpose of this study is to confirm the accuracy of LES in modeling plume dispersion in a simple street canyon model and to clarify the mechanism of the discrepancy in relation to RANS computation. Simple LES modeling is shown by comparison with wind ...
متن کاملInfluence of Reckless Jaywalking on Urban Road Traffic Capacity
A modified cellular automaton (CA) model based on the NaSch model is proposed to simulate the typical reckless jaywalking which can cause serious traffic jam and even traffic accident. Incorporating traffic psychology, the walking characteristics such as customary activity, randomness, conformity and tendency are analyzed. Two parameters reflecting the influence degree of human factor is introd...
متن کاملthermal effect on pollutant dispersion in an urban street canyon
his investigation was carried out to reveal the impact of solar radiation on wind flow structure and pollutant dispersion in an urban street canyon of aspect ratio of one using the computational fluid dynamic (cfd) technique. the simulation results (velocity and concentration data) show that heating from building wall surfaces and ground lead to strong buoyancy forces as the air is heated by th...
متن کاملLand use regression modeling of intra-urban residential variability in multiple traffic-related air pollutants
BACKGROUND There is a growing body of literature linking GIS-based measures of traffic density to asthma and other respiratory outcomes. However, no consensus exists on which traffic indicators best capture variability in different pollutants or within different settings. As part of a study on childhood asthma etiology, we examined variability in outdoor concentrations of multiple traffic-relat...
