There is an increasing demand in traffic monitoring of densely populated urban areas. In our approach we use a priori information of roads location and focus on vehicle queues detection. In this imagery single vehicles are merged to either dark or bright ribbons and therefore can hardly be separated. The queues can be extracted as lines in scale space using a differential geometric approach. We...

Due to increasing traffic there is high demand in traffic monitoring of densely populated urban areas. In our approach we focus on the detection of vehicle queues and use a priori information of roads location and direction. In high resolution satellite imagery single vehicles can hardly be separated since they are merged to either dark or bright ribbons. Initial hypotheses for the queues can b...

Leo Moser asked what is the region of largest area that can be moved around a right-angled corner in a corridor of unit width. Similarly, what is the region of largest area that can be reversed in a T junction made up of roads of unit width? Can a specific 3-dimensional object pass through a given door? Our survey aims at showing that mover problems are no less challenging even if there are no ...

This paper reports the findings from a study aimed at examining the effectiveness of shoulder rumble strips in reducing run-off-the-road (ROR) crashes on two-lane rural highways using the empirical Bayes (EB) before-and-after analysis method. Specifically, the study analyzed the effects of traffic volume, roadway geometry and paved right shoulder width on the effectiveness of shoulder rumble st...

Speed and traffic volume data are collected on different sections of four lane and six lane roads in three metropolitan cities in India. Speed data are analyzed to fit the statistical distribution to individual vehicle speed data and all vehicles speed data. It is noted that speed data of individual vehicle generally follows a normal distribution but speed data of all vehicle combined at a sect...

Updating of navigation databases is an important task to ensure a high level utilization of navigation data. For example, in fundamental topographic databases roads are often represented as a single line without detailed connectivity and traffic flow information, but for a navigation database, roads separated by physical barriers should be represented as two roads with different traffic flow di...

Treatment of waste water containing ethylene glycol (EG) by implementing a sequence of two Moving Bed Biofilm Reactors (MBBR) were studied. Reactors were operated at different hydraulic retention times (HRT) of 48, 24, 18, and10 hours while EG concentration was in the range of 10 mg/l to 1,150 mg/l. Throughout the experiments the ratio of EG Chemical Oxygen Demand (COD) to total COD was changed...
