Because of the difficulty of modeling the traffic conditions on a roadway network, little has been achieved to date in area control using dynamic traffic volume. The most commonly practiced method for timing control of area signals that takes into account traffic volume changes is time-interval-dependent control. This type of control strategy assumes that the traffic volume on each roadway of a...

According to the forensic statistics, in Iran, 26 percent of those killed in traffic accidents are motorcyclists in recent years. Thus, it is necessary to investigate the causes of motorcycle accidents because of the high number of motorcyclist casualties. Motorcyclists' dangerous behaviors are among the causes of events that are discussed in this study. Traffic signs have the important role of...

In recent past, significant efforts have been made to improve the scientific understanding of exhaust dispersion phenomenon in urban street canyons/intersection. The amount of turbulence generated by natural winds within the street canyon might be smaller than that of traffic induced turbulence. Therefore, the influence of traffic-induced turbulence on exhaust dispersion has to be quantified. I...

As computer networks scale up in size and traffic volume, detecting slow suspicious activity, deliberately designed to stay beneath the threshold, becomes ever more difficult. Simply storing all packet captures for analysis is not feasible due to computational constraints. Detecting such activity depends on maintaining traffic history over extended periods of time, and using it to distinguish b...

In control of urban traffic systems, synchronization of traffic lights is one of the measures used to improve the throughput, as it allows vehicles to pass an arterial without stop. Classical approaches are off-line, top-down planned and centralized. Moreover, they are inflexible since they cannot cope with dynamic changes in the traffic flow or depend too much on communication. This paper desc...
