today, the motorcycle riders in the streets as traffic congestion have become a challenge. if we do not have planning and scientific management for this problem, consequently the volume of traffic and accidents, crime, social damages will be increased. considering the importance of the issues, identify and assess the factors promote traffic safety, reduce crime and social problems with motorcyc...

Modeling and Estimation Techniques for Understanding Heterogeneous Traffic Behavior. (May 2004) Zhili Zhao, B.S., East China Normal University; M.S., Shanghai Institute of Technical Physics, Chinese Academy of Sciences Chair of Advisory Committee: Dr. A. L. Narasimha Reddy The majority of current internet traffic is based on TCP. With the emergence of new applications, especially new multimedia...

Traffic state estimation from the floating car system is a challenging problem. The low penetration rate and random distribution make available floating car samples usually cover part space and time points of the road networks. To obtain a wide range of traffic state from the floating car system, many methods have been proposed to estimate the traffic state for the uncovered links. However, the...

Traffic flow/volume data are commonly used to calibrate and validate traffic simulation models. However, these generally obtained from stationary sensors (e.g. loop detectors), which expensive install maintain cover a small number of locations in the transport network. On other hand, Floating Car Data (FCD) readily available at network level, usually sample vehicles. We present an indirect flow...

Abstract Accurate traffic density plays a pivotal role in the Intelligent Transportation Systems (ITS). The current practice to obtain is through specialized sensors. However, those sensors are placed limited locations due cost of installation and maintenance. In most metropolitan areas, surveillance cameras widespread road networks, they potential data sources for estimating whole city. Unfort...

The traffic congestion problem in urban areas is worsening since traditional traffic signal control systems cannot provide] efficient traffic regulation. Therefore, dynamic traffic signal control in Intelligent Transportation System (ITS) recently has received increasing attention. This study devised a multi-agent architecture, the Adaptive and Cooperative Traffic light Agent Model (ACTAM), for...

The purpose of self-sizing networks is to provide efficient utilization of network resources while ensuring appropriate Quality of Service (QoS) for each class of traffic. Bandwidth estimation, which estimates the amount of a traffic bandwidth, is useful to allocate proper bandwidth in order to meet a QoS requirement. This paper concerns an hardware implementation of a Configurable Bandwidth Es...

Air traffic forecast is among the most important functionalities of air traffic controls. The Linear Dynamic System Model that predicts the traffic demand within the Air Route Traffic Control Centers serves well for this purpose. This model formulates inflows and outflows between Centers’ boundaries by assuming that the boundary crossings between Centers are in conformance with Poisson distribu...
