In order to reveal the influence of different traffic classes on the Internet, backbone traffic was collected within an eight month period on backbone links of the Swedish University Network (SUNET). The collected data was then classified according to network application. In this study, three traffic classes (P2P, Web and malicious) are compared in terms of traffic volumes and signaling behavio...

The purpose of this study was to investigate traffic flow characteristics at off-ramp junctions in Iranian expressways. The study was conducted on the traffic behavior in isolated off-ramp vicinity of 6-lane expressways. The database consisted of traffic flow and traffic speed information extracted from videotapes. The relationship between diverging traffic flow in the right lane of expressway ...

background: to reduce traffic injuries in the country, health professionals should have accurate estimates of road traffic deaths. multiple and sometimes inconsistent statistics presented by organizations in charge create high degree of uncertainty for planners and decision makers. to achieve an accurate estimate, several methods are available. of them, capture-recapture method seems to be an a...

this paper is a case study of the cause of distress and evaltion of main runway (29 l-ll r) of mahrabad international airport in 1320 , this run way was built (1800 length & 60 width ) from pcc for small aircrafts. later on 1329 and 13 39 the length of this run way was inc reased to 3000 m and 4000m , respectedly was increased to 3000m and 4000m,respectedly .since 1320, this run wa y h a s bee ...

The performance of many traffic control strategies depends on how much the traffic flow models have been accurately calibrated. One of the most applicable traffic flow model in traffic control and management is LWR or METANET model. Practically, key parameters in LWR model, including free flow speed and critical density, are parameterized using flow and speed measurements gathered by inductive ...

Traffic oscillation, stop and go traffic, is created by different reasons such as: sudden speed drop of leader vehicle. Stop and go traffic commonly is observed in congested freeways results in traffic oscillation. Many theories had been presented to define congestion traffic based on laws of physics such as: thermodynamics and fluid. But, these theories could not explain the complexity of driv...

Most of the universities around the world are offering online distance learning programs. A framework is required that can handle huge amount of network traffic at the servers and also cater for the autonomous, robust, intelligent load balancing and fault tolerance. In order to handle large number of transactions at the server, high performance server architecture is required. The proposed fram...

accidents allocate more than 30 percent causes of mortality and are the most common reason of mortality in children after one year old. thus, in order to provide children health, education of road safety is essential and children should be more aware about road safety necessities and learn  the methods of life maintenance proportionate with own age and needs. there is a significant note that ed...
