This paper presents a methodology for recognizing, identifying and classifying built objects in dense urban areas, using a morphospectral approach applied to VNIR/SWIR hyperspectral image (HySpex). This methodology contains several image processing steps: Principal Components Analysis and Laplacian enhancement, Feature Extraction of segmented build-up objects, and supervised classification from...

The present paper analyses local economic development issues through the prism of urban governance theories and models. From theoretical corpora to empirical LED case studies, we emphasise, through the anarchy paradigm, the privatisation tendencies of urban planning and development projects in local territories. We have taken an interest in comparative analysis of principal concepts and ...

Abstract Disturbance to the moving traffic, such as on-street parking and bus stop on carriageway normally called side friction in literature, is one of major problems that impact vehicular speed urban arterials developing countries like India. Regression model study mode-wise speeds using other influencing variables faces problem multicollinearity there a strong correlation between independent...

Past research has found a non-linear relationship between traffic intensity or level of service (LOS) and highway crash rates. This paper investigates this relationship further by including the effects of site characteristics and estimating Poisson regression models for predicting single and multi-vehicle crashes separately. Analysis focuses on rural two-lane highways, with hourly LOS, traffic ...

In this research article, household wealth indices are calculated to estimate the sampling errors, which gave us complete information on quality and reliability of published data upon surveys. Estimates based simple random sampling, contains errors. Here principal components analysis (PCA) standard errors as orthogonal transformation develop solid measures individual economic status. These eval...

The project aims to develop, test and apply a Geographical Information System (GIS) for modelling access for wheelchair users in urban areas. The principal focus is to provide a GIS system that will work as a decision support and mapping tool for urban planners. In addition, the system has been designed to encompass future developments, including use as a guidance device to help wheelchair user...

Using data of the third round of the National Family Health Survey (NFHS) 2005-2006, this study examined the prevalence of overweight and obesity among women from different economic strata in urban India. The study used a separate wealth index for urban India constructed using principal components analysis (PCA). The result shows that prevalence of overweight and obesity is very high in urban a...

Understanding urban population migration patterns is very helpful for urban operation and management, including the traffic forecasting, epidemic prevention, commercial resource allocation, emergency response and future urban planning. The large taxi fleet equipped with GPS comprises ubiquitous mobile probes in urban areas, and their trajectories reveal interesting phenomena in the city. We inv...
