We put forward architecture of a framework for integration of data from moving objects related to urban transportation network. Most of this research refers to the GPS outdoor geolocation technology and uses distributed cloud infrastructure with big data NoSQL database. A network of intelligent mobile sensors, distributed on urban network, produces congestion traffic patterns. Congestion predic...

Traffic control schemes for ATM networks can be classified into two categories: reactive congestion control and preventive congestion control. Reactive congestion controlcan be effective in ATM local area networks as well as preventive congestion control. A possible scheme to realize efficient reactive congestion control is a switch architecture, which possesses buffers on both sides of input a...

A TCP flow is congestion responsive because it reduces its send window upon the appearance of congestion. An aggregate of nonpersistent TCP flows, however, may not be congestion responsive, depending on whether the flow (or session) arrival process reacts to congestion or not. In this paper, we describe a methodology for the passive estimation of traffic congestion responsiveness. The methodolo...

Traffic congestions are formed by many factors; some are predictable like road construction, rush hour or bottle-necks. Drivers, unaware of congestion ahead eventually join it and increase the severity of it. The more severe the congestion is, the more time it will take to clear. In order to provide drivers with useful information about traffic ahead a system must: Identify the congestion, its ...

Costs associated with traffic externalities such as congestion, air pollution, noise, safety, etcetera are becoming unbearable. The Braess paradox shows that combating congestion by adding infrastructure may not improve traffic conditions, and geographical and/or financial constraints may not allow infrastructure expansion. Road pricing presents an alternative to combat traffic externalities. T...

Traffic congestion identification is a popular research topic of Intelligent Transportation System (ITS). Many identification methods, such as threshold value based methods, California, McMaster method and so on, have been studied. But the threshold values of these methods are difficult to be determined. A novel threshold value based traffic congestion identification method is proposed in this ...
