Many researchers use abstract models to simulate network congestion, finding patterns that might foreshadow onset of congestion collapse. We investigate whether such abstract models yield congestion behaviors sufficiently similar to more realistic models. Beginning with an abstract model, we add elements of realism in various combinations, culminating with a high-fidelity simulation. By compari...

The use of information technology affects the congestion transport network. Coordinated control is designed to ensure non-stop passage a group cars through all regulated intersections highway at certain speed. As part application latest technologies, following indicators quality transportation can be improved: timeliness transportation, safety, economic indicators, speed, services.

In data networking and queuing theory, network congestion occurs when a link or node is carrying so much data that its quality of service deteriorates. Typical effects include queuing delay, packet loss or the blocking of new connections. A consequence of these latter two is that incremental increases in offered load lead either only to small increases in network throughput, or to an actual red...
