Driving simulators are useful and effective tools for conducting studies in the field of traffic safety. Simulation sickness (SS) sense presence (SP) two well-known factors that could affect results driving simulator experiments. This study investigated relationship between SP SS a medium-fidelity simulator. Additionally, impact road environment (urban arterials or rural expressways) on these s...

In this paper, we present a hybrid approach, robust principal component geographically weighted regression (RPCGWR), in examining the land change as a function of both extant urban land use and the effect of social and environmental factors in the Twin Cities Metropolitan Area (TCMA) of Minnesota. We used remotely sensed data to treat urban land use via the proxy of impervious surfaces. We then...

BACKGROUND There are large differences in the prevalence of atopic disease between urban and rural areas of developing countries, without good explanation. Diet has been associated with atopic disease, but studies of specific nutrients are contradictory, cross-sectional studies often being unsupported by trials. We investigated diet as an explanation for the difference in the prevalence of atop...

2. Government has undertaken its own urban renewal projects for many years. The Hong Kong Housing Society (HS) started its Urban Improvement Scheme in 1974. In 1988, the Land Development Corporation (LDC) was established to speed up the process of urban renewal. The Housing Authority (HA) has also played an important role in urban renewal, in particular by redevelopment of its own estates and a...

IN T R O D U C T IO N Small cities have minor traffic congestion which occurs on major arterials. Primarily because of the importance of the central business district (C B D ), the greatest traffic delays result from the morning, noon and evening peak flows to, from and through the city center. In addition, the points within any size urban area of highest vehicle delay are at the signalized int...

Coordinated actuated traffic signal systems have been widely deployed in urban and suburban areas as they provide progression along the major corridors. However, it has been often observed that uncoordinated cross street movements experience higher delay under the coordinated actuated signal systems due to their inability to adjust maximum green times (or force-off points). A few studies mentio...

OBJECTIVES In urban settings, pedestrian fatalities and injuries are concentrated on major roads. This study aims to describe urban intersections with major roads (arterials and collector roads) and explore the association between intersection characteristics and injured pedestrians. METHODS From a stratified random sampling in Montréal, Quebec, 512 intersections were selected and their chara...

Improperly scheduled signal timing plans are one of the main reasons for reduced efficiency traffic signals at coordinated urban arterials. Recently, most arterial roads equipped with intelligent transportation systems devices capable reporting collected data on high temporal and spatial resolution, which gives us opportunity to overcome traditional planning flaws. Previous studies have propose...

Road accident prediction plays an important role in accessing and improving the road safety. Besides the conventional generalized linear regression, the prediction approaches based on fuzzy logic and neural networks have increasingly been proven to have a significant accident-predicting capability in recent years. However, fuzzy logic and neural network have their respective limitations. For ex...
