Designing pedestrian systems have been a challenge due to the lack of effective tools and methods to model the autonomous behavior of pedestrians. Pedestrians are one of the main players in traffic systems, and they also are their most common victims. The high incident of pedestrians’ accidents has led the World Health Organization (WHO) to set the reduction of traffic accidents as a priority f...

This paper presents the functionality of the Visual Interactive System for Transportation Algorithms (VISTA) that utilizes a mesoscopic/microscopic simulation called RouteSim and a Dynamic Traffic Assignment (DTA) routine to emulate the behavior of individual drivers and how they distribute themselves into the transportation network. The principal output of the model is the path chosen by every...

In a world that is increasingly reliant on automobiles, efficient management of the transportation network is a key functionality of intelligent transportation systems (ITS). A wide range of these ITS applications rely on the extraction of current data as well as historical information in order to perform appropriately. This work presents a novel computer vision based approach for traffic manag...

Sensor networks enable a wide range of applications in both military and civilian domains. However, the deployment scenarios, the functionality requirements, and the limited capabilities of these networks expose them to a wide-range of attacks against control traffic (such as wormholes, rushing, Sybil attacks, etc) and data traffic (such as selective forwarding). In this paper we propose a fram...

The last fifteen years has seen a vast proliferation of middleboxes to solve all manner of persistent limitations in the Internet protocol suite. Examples include firewalls, NATs, load balancers, traffic shapers, deep packet intrusion detection, virtual private networks, network monitors, transparent web caches, content delivery networks, and the list goes on and on. However, most smaller netwo...

Timely response to the impact of climate change is a big challenge for whole world, especially developing countries. Within framework country's transportation system, bridges play crucial role in maintaining an efficient and well-connected road network. Ensuring their functionality paramount importance. However, poses serious risks damage bridge structures, jeopardizing traffic safety potential...

The existing wireless network will face the challenge of data tsunami in the near future. Densification of network will deal huge data traffic but will increase the interferences and network cost. At the same time, the existing wireless network is underutilized due to dynamic traffic. To deal with this adverse scenario, a change in the current network architecture is required. Based on virtuali...

A RMON agent system, which locates on a subnet, collects the network traffic information for management by retrieving and analyzing all of the packets on the subnet. The RMON agent system can miss some packets due to the high packet analyzing overhead when the number of packets on the subnet is huge. In this paper, we have developed a light-weight RMON agent system that can handle a large amoun...

An adaptive gridless OXC is implemented using a 3D-MEMS optical backplane plus optical modules (sub-systems) that provide elastic spectrum and time switching functionality. The OXC adapts its architecture on demand to fulfill the switching requirements of incoming traffic. The system is implemented in a seven-node network linked by installed fiber and is shown to provide suitable architectures ...

This paper presents a fuzzy-based system that is used for maintenance planning of road pavements. The system has been developed based on knowledge elicitation from experienced maintenance engineers using fuzzy logic. The system includes functions for pavement condition and deterioration prediction, feasible treatment assessment in each pavement section, and maintenance planning in a road networ...
