This paper presents Tstat [1], a new tool for the collection and statistical analysis of TCP/IP traffic, able to infer TCP connection status from trace data. Discussing its use, we present some of the performance figures that can be obtained and the insight that such figures can give on TCP/IP protocols and the Internet. While field measures have always been the starting point for networks plan...

Purpose: The purpose of the study was to evaluate the effect of different gradations of noise reduction (NR) algorithm in hearing aids, through acoustical and perceptual measures. Methods: The output of the hearing aid with NR at three gradations (minimum, medium and maximum) and without NR, at 0 dB signal to noise ratio (SNR) across three types of noise (cafeteria, speech babble, and traffic n...

In the United States, hundreds of people lose their lives each year and many more are injured due to vehicle crashes in the work zones. Over the years, temporary traffic control (TCC) measures have been developed and deployed in work zones. To continuously improve the safety, there is a need to identify the traffic control deficiencies in work zones by evaluating the effectiveness of existing T...

58 Abstract— Introducing Internet traffic anomaly detection mechanism based on large deviations results for empirical measures. Using past traffic traces we characterize network traffic during various time-of-day intervals, assuming that it is anomaly-free. Throughout, we compare the two approaches presenting their advantages and disadvantages to identify and classify temporal network anomalies...

Traffic congestion in highway networks is one of the main issues to be addressed by today’s traffic management schemes. Automation combined with the increasing market penetration of on-line communication, navigation, and advanced driver assistance systems will ultimately result in intelligent vehicle highway systems (IVHS) that distribute intelligence between roadside infrastructure and vehicle...

Traffic management measures may be implemented to make use of the road traffic network as efficient as possible. Therefore, it is an important field of research for traffic researchers. Potential traffic management measures first have to be proven theoretically. However, before the decision is made to implement these measures in real-life, their effectiveness has to be tested. Road traffic invo...

the police are competent and always present contact persons who have direct knowledge and experience and act as role models in the area of road traffic. one of the focuses of police work is to increase tolerance and consideration, especially for more vulnerable road users. the priorities of the police are geared at emphasizing how relevant and appropriate the decisions made by road traffic auth...

A unified method for statistical anomaly detection in intrusion detection systems is theoretically introduced. It is based on estimating a dispersion measure of numerical or symbolic data on successive moving windows in time and finding the times when a relative change of the dispersion measure is significant. Appropriate dispersion measures, relative differences, moving windows, as well as tec...

We develop an anticipative model-based predictive traffic control approach for ramp metering in freeway traffic networks. If ramp metering is implemented in a freeway network with alternative routes, traffic can spontaneously re-route due to the response of the drivers to the applied control actions. Although spontaneous re-routing can have a significant influence on the resulting traffic situa...
