An Analysis of Traffic Behavior at Freeway Diverge Sections using Traffic Microsimulation Software
Microscopic simulation traffic models are widely used by transportation researchers and practitioners to evaluate and plan for transportation facilities. The intent of these models is to estimate the second-by-second vehicle movements and interactions on such facilities. Due to constraints related …

Coding and Transmission of Digital Video on the Internet
… problem by conducting a comprehensive Internet traffic behavior study and we use the results as guidelines for the design and implementations of a low bitrate and robust video coding and transmission scheme. This thesis tackles problems in both coding and transmission. For coding, a hybrid …

Analysis of Freeway Weaving Areas Using Corridor Simulator and Highway Capacity Manual
Weaving is defined as the crossing of two or more traffic streams traveling in the same direction along a significant length of the highway without the aid of traffic control devices . The traditional methods used for design and operational analysis of a highway is the Highway Capacity Manual …

Efficient and robust routing of highly variable traffic
… Internet are characterized by highly variable traffic behavior over time that is difficult to predict. Classical approaches to network design rely on a model in which a single traffic matrix is estimated. When actual traffic does not conform to such assumptions, desired bandwidth guarantees …

Session-based Intrusion Detection System To Map Anomalous Network Traffic
… ID systems determine what is normal traffic within a network and reports abnormal traffic behavior. This paper will describe a methodology towards developing a more-robust Intrusion Detection System through the use of data-mining techniques and anomaly detection. These data-mining …

Network anomaly detection using management information base (MIB) network traffic variables
… through monitoring the subtle changes of network traffic patterns. The process of measuring network traffic pattern is achieved by monitoring the Management Information Base (Mifi) II variables, supplied by the Simple Network Management Protocol (SNMP) LI. The MAD system then converted each …

A fast and adaptive threat detection and prevention architecture
… by capturing both legitimate and malicious traffic and compare two ways of combining packets into flows, one gathering all packets in a time window and the other analyzing only the first few packets of each flow. Besides our created dataset, we also analyze our proposal on real data composed …

Contract-based safety verification for autonomous driving
… safe with respect to probabilistic models of traffic behavior, and ensure that it will follow the rules of the road. We generate contracts using reachability analysis in a reach-avoid problem under consideration of dynamic obstacles, i.e., other traffic participants. Contracts are then derived …

Shape based classification and functional forecast of traffic flow profiles
<p>This dissertation proposes a methodology for traffic flow pattern analysis, its validation, and forecasting. The shape of the daily traffic flows are directly related to the commuter’s traffic behavior which merit analysis based on their shape characteristics. As a departure from the traditional …

Development of dynamic recursive models for freeway travel time predictions
Traffic congestion has been a major problem in metropolitan areas, which is caused by either insufficient roadway capacity or unforesceable incidents. In order to promote the efficiency of the existing roadway networks and mitigate the impact of traffic congestion, the development of a sound …

The Design of A Multi-party VoIP Conferencing System
… them into different categories according to the traffic behavior. After studying the conversational dynamics in the multi-party system, we identify user-observable metrics that affect the perception of conversational quality and study their trade-offs. Based on the dynamics and the Internet …

Studying the technical challenges of a customizable multi-user multi-modal simulation platform for traffic safety research
Understanding traffic behavior is critical to ensuring the safety of our roads and all those who use them. Traffic psychologists and engineers utilize a variety of techniques such as large-scale field observations, computational modeling, and simulation in attempts to recognize dangers and give …

Towards a Comprehensive Bicycle Motion Behavior Model and Naturalistic Cycling Dataset
Most of the existing bicycle flow traffic research is limited to characterizing the longitudinal motion of bicyclists based on the assumption that there is no significant differences between the dynamics of a single-file bicycle traffic and the longitudinal motion behavior of cars. This research …
