In this research, the centers involved in relief operations in Tehran traffic area districts have been compared and the supply-demand ratio has been specified through a relation presented separately for each district. The supply has been evaluated based on three parameters: 1) No of relief centers, 2) congestion of the main road (the ratio of the length of the main road to the area of the distr...

This report describes an autonomous mobile robot designed to navigate at high speeds over featureless terrainterrain which is not navigable by relying on features that are found on paved roads and highways. To this end we have developed a paradigm that we call position bused navigation that relies on explicit vehicle position information from inertial and satellite instruments, to navigate. Spe...

This study investigated factors associated with road traffic noise and residents’ annoyance from three distinct types of roads (major arterial, minor collector roads). Nine sampling locations in Thailand’s Nakorn Pathom Province were chosen for the measurement levels contributing characteristics: volume, vehicle speed, proportion heavy to total vehicles. Along a housing survey, face interviews ...

This research tends to analyze and assess the impact of intercity flows rate on land use changes around the community roads of the cities of Babol, Ghaem Shahr and Sari. This research is descriptive-analytic and performed in quantitative method. A wide range of techniques including gravity model, flow analysis model, entropy analysis and GIS software environment were applied for performing requ...

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...
