We have empirically observed that the average volume change across flows is close to zero in links carrying a large enough number of flows. This flow equilibrium property holds if the flows are nearly independent, and it is violated by traffic changes caused by several, potentially small, correlated flows. Many traffic anomalies fit this description, including scans, DDoS attacks, and routing s...

Marupudi, Surendra Brahma. M.S., Department of Computer Science and Engineering, Wright State University, 2016. Framework for Semantic Integration and Scalable Processing of City Traffic Events. Intelligent traffic management requires analysis of a large volume of multimodal data from diverse domains. For the development of intelligent traffic applications, we need to address diversity in obser...

Traffic is a sector that has growing problems facing the challenges that the Kyoto protocol suggests for global climate protection. The problems seem to be worsening as well in less developed as in the more developed countries. Europe is no exception in this manner, since the CO 2 emissions have increased at the same rate as traffic volumes in the late 1980's and in the 1990's, despite of techn...

Because of heavy weights and large turning radii, large truck (LT) movements have very different characteristics than those of smaller vehicles, such as passenger cars. This difference makes collection of LT volume data very important for accurate analysis of traffic stream characteristics in transportation planning and engineering. Since LT travel patterns are seasonal, data obtained by survey...

Traffic control devices are one of the most significant factors affecting driving behavior. In China, there is a lack of installation guidelines or standards for traffic control devices in school zones. In addition, little research has been done to examine the effects of traffic control devices on driving behavior. Few guidelines have been established for implementing traffic control devices in...

Traffic induced turbulence coupled with natural air motions becomes an important variable affecting the dispersion of exhaust emissions, especially under low wind conditions. A flexible model vehicle movement system (ƒMVMS) for an urban intersection having two-way straight and radial peripheral traffic flows has been designed, fabricated and made operational in the EWT to study the traffic indu...

In this research, we propose an electro-sensitive traffic light using the smart agent algorithm to reduce traffic congestion and traffic accidents. The multi-agent system approach can provide a new and preferable solution. The proposed method adaptively controls the cycle of traffic signals even though the traffic volume varies. Consequently, we reduce the car waiting time and start-up delay ti...

The jam flow condition is one of the main traffic states in traffic flow theory and the most difficult state for sectional traffic information acquisition. Since traffic information acquisition is the basis for the application of an intelligent transportation system, research on traffic vehicle counting methods for the jam flow conditions has been worthwhile. A low-cost and energy-efficient typ...

High speed data transmission is foreseen to count for the main volume of mobile traffic consumption in the future wireless networks. Moreover, 80% of the data traffic is expected to be generated inside of buildings, i.e., an office building, airport or on campus. Along with the fast evolution of data traffic need (traffic volume and peak data rates), it will become extremely difficult to serve ...

The Traffic Engineering Department of the City of Fort Wayne recently conducted a before-and-after study of traffic volume trends and speed-delays encountered on the east and west one-way street system now in operation as compared to two-way street movement. This study was confined to the central business district only, as the traffic survey and recommendations were basically confined within th...
