The AQM (Active Queue Management) Algorithm such as RED, PI, REM have too long respond time and some other problems. Though it makes some enhancement, the PID (Proportional Integral Differential) active queue management algorithm can not make the queue length converge to expectation with longer delay. Because of self-adapt control of BP (back-propagation) neural network, this issue bring forward a...
This paper studies a common traffic problem in China: a large number of bus lines share the same stop. In rush hours, a long queue of buses waiting to get into the stop, which causes a rise of bus delay and a drop of traffic capacity nearby. First, a cellular automaton model is proposed to simulate such traffic scenarios. Second, to re-designing such busy bus stops to enhance efficiency, some principles...
IP networks are more and more used to transport real-time services. A crucial factor for real-time services is the end-to-end delay experienced by the application. The contribution resulting from the queuing delay induced by the network nodes is the most difficult to calculate. Under assumptions of real-time traffic behaviors and network nodes behaviors, the transportation of real-time traffic is...
The emergence and dissipation of queue before saturated intersection in urban traffic network is analyzed. A dynamic variational inequality assignment model in saturated urban traffic network is proposed based on a boundary equilibrium concept. This concept is used to deal the saturated signalized intersections as bottlenecks based on saturated flow and green split to simplify the calculation of queuing...
