A new theoretical approach for the determination of capacities at All-Way Stop-Controlled intersections is presented. This approach is based on the Addition-Conflict-Flow method developed from the graph theory. The point of view related to the traffic streams in contrast to existing procedures, which handle only the approaches allows a systematic and realistic analysis of the traffic process at...

Vehicle traffic flow channelizing can significantly contribute to fewer collisions and smooth in isolated signalized intersection design. Therefore, this study investigates the effect of changes number right-turn lanes with splitter islands left-turn storage bays for different volume approaches on performance. This aims provide an accurate analysis estimate such intersections, which improve Fur...

A protected left turn phase is often used at intersections with heavy left turns. This may induce a capacity gap between adjacent intersections along the arterial road among which only parts of intersection are with protected left turn phase. A model for integrated optimization of protected left turn phases for adjacent intersections along the arterial road is developed to solve this problem. T...

Title of Document: LONGITUDINAL SPACE-CHARGE WAVES INDUCED BY ENERGY MODULATIONS Brian L. Beaudoin, Master of Science, 2008 Directed By: Professor Patrick G. O’Shea and Professor Rami A. Kishek Department of Electrical and Computer Engineering High intensity beams that are space-charge dominated are important for applications such as free electron lasers that require high intensity and low emit...

Electronic Orientation Aids (EOA) usually guide visually impaired pedestrians using turn-by-turn instructions. However, several studies have demonstrated that mental representations of space seem difficult to build when turn-by-turn instructions only are provided. This is a crucial point as getting an accurate spatial representation of the surroundings can make the difference between successful...

A fast photodiode was demonstrated to be able to extract the turn by turn photon beam profile information of electron storage rings if the photodiode was operated at the saturated region. When applied this method to a 1.3 GeV synchrotron light source with 200 mA beam current, the synchrotron radiation intensity is not intense enough to saturate the photodiode. To apply this method to the type o...

Researches using existing statistics and data collected from the area of study help officials at decision-making, to improve the region's problems, like the problem of the high rate of accidents in the region, despite the low volume of daily service. The uses of roundabouts in many parts of the world have many advantages over intersections, amongst them are increased safety and capacity and red...

Copy Summary: It has been found that humans not only tend to avoid the middle routes and prefer the peripheral routes among multiple choices, but also rely on the ‘initial segment strategy’ to select the route. In this paper, we propose a new heuristic which humans apply during route selection: Participants prefer the route whose initial direction lies in the direction of their final destinatio...
