Providing healthy food and protecting sources from pollution has been one of the concerns of human societies and decision – making centers so that protecting food from pollution, detecting sources of pollution and measuring them become important. Because of nutritive and political significance of grape in this area, extensive use of leaf and fruit of this plant, developing urban areas around gr...

This paper aims at investigating the heterogeneous characteristics among truck drivers in route choice preferences. A latent class model incorporating membership functions is employed to examine differences between segments of drivers. A stated choice experiment designed for identifying route choice behavior of truck drivers provides the data for model estimation. The effects of road pricing an...

The study illustrates the use of Geographic Information System (GIS) tools and numerical Multi-Criteria Evaluation (MCE) techniques for selection of suitable sites for urban development of a hill town. This study was conducted to identify suitable sites for urban development of a hill town, Nahan using GIS-based multi-criteria evaluation of slope, road proximity, land use, land values, soil and...

the theory of urban ecology is based on explaining urban spatial structure, studying and describing the reciprocal relationship between human societies in the urban areas and the environment, as well as analyzing the circumstances of urban population segregation and production of everyday life spaces. to study and explain urban ecological structure of mashhad, the case study of the article, we ...

to cope with the urban congestion problem resulted from rapid urbanization some cities are successfully using electronic road pricing policy as a demand management measure. in 1982, hong kong governmenttook initiative to experiment electronic road pricing in hong kong. though, the project outcome reveals that electronic road pricing could bring tremendous economic, social and environmental bene...

Accurate and continuous vehicle localization in urban environments has been an important research problem in recent years. In this paper, we propose a landmark based localization method using road signs and road markings. The principle is to associate the online detections from onboard cameras with the landmarks in a pre-generated road infrastructure database, then to adjust the raw vehicle pos...

This conference paper presents an accident study investigating where fatal alcoholand drugrelated accidents occur with respect to traffic environment (i.e., urban versus rural), road type, speed limit, annual average daily traffic flow, and road category. The study uses data from indepth studies of fatal accidents and from the Swedish National Road Database. Accident data from the 2006–2009 per...

The impact of road dust emissions on PM10 and PM2.5 (atmospheric particulate matter with diameteer < 10 μm and 2.5 μm mass concentrations recorded from 2003 to 2010 at 11 locations (rural, urban and industrial) in southern Spain was estimated based on the chemical characterization of PM and the use of a constrained Positive Matrix Factorization, where the chemical profile of local road dust sam...
