Background: This study attempted to investigate traffic accident fatalities during 2004-2009 and the effect of fuel rationing on traffic accident fatalities .   Materials and Methods: This was a cross-sectional study on available data of all traffic accident fatalities in Fars Province, Iran, during 2004-2009. To identify and fit the best model, various instruments, including the...

due to increasing growth of air traffic, it is very important to have a reliable air traffic control system. usually secondary surveillance radar systems are employed for this task. in this paper, a new approach is presented to identify interrogators location of this system. the proposed method works passively and uses just a single receiver. this goal has been reached using angle and time diff...

This paper examines a short-time estimation problem of an origin-destination (OD) matrix, where each element is a volume of vehicle flow between one of the OD pair of zones of a signalised junction. The estimation is based on the use of traffic measurements provided by video sensors and on the knowledge of the traffic lights. This data is subject to redundancy, imprecision and uncertainty. The ...

In present scenario of research, network congestion is one of the most interesting area. Congestion in internet is a long-standing problem and in modern days internet service providers use congestion control and congestion avoidance techniques to avoid congestion collapse. Internet congestion appears when a large volume of data is being routed on low bandwidth lines or across networks that have...

Annual average daily traffic (AADT) values have long played an important role in transportation design, operations, planning, and policy making. However, AADT values are almost always rough estimates based on the closest short-period traffic counts, factored up using permanent automatic traffic recorder data. This study develops Kriging-based methods for mining network and count data, over time...

As we seen everyday vehicle traffic increases day by day on road is causing many issues. We face many traffic jams due to the inefficient traffic controlling system which is unable to cope up with the current scenario of traffic in our country. To overcome such drastic scenario and looking at current traffic volume we need to develop a system which works on real time processing and works after ...

identification of the best vegetation indices (vis) for use in quantitative analyzes of vegetation is one of the important issues for ecologists. the objective of this study was sensitivity evaluation of vegetation indices to a stand volume for identification of the best vegetation index (vi) in stand volume estimation using a statistical sensitivity method. also, another objective of this stud...

The contents of this report reflect the views of the authors, who are responsible for the facts and the accuracy of the information presented herein. Travel time, one of the most important freeway performance metrics, can be easily estimated using the data collected from fixed traffic sensors, avoiding the need to install additional travel time data collectors. This project is aimed at fully ut...

Objective The hippocampal circuit integrity is crucial for learning and memory. Despite the existing reports on hippocampal–dependent memory impairment due to noise stress, there are only a few studies on the effect of noise stress on anatomical structure of hippocampus. The present study is aimed to investigate the likely effects of chronic noise exposure on the volume of rat hippocampus. Mate...
