We study how to estimate real time queue lengths at signalized intersections using intersection travel times collected from mobile traffic sensors. The estimation is based on the observation that critical pattern changes of intersection travel times or delays, such as the discontinuities (i.e., sudden and dramatic increases in travel times) and non-smoothness (i.e., changes of slopes of travel ...

In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...

We examine two extensions of traditional single-node packet-scale queueing models: tandem networks and (strict) priority systems. Two generic input processes are considered: periodic and Poisson arrivals. For the two-node tandem, an exact expression is derived for the joint distribution of the total queue length, and the queue length of the first queue, implicitly determining the distribution o...

This paper presents a problem of queuing theoretic performance modeling and analysis of Orthogonal Frequency Division Multiple Access (OFDMA) under broad-band wireless networks. We consider a single-cell WiMAX environment in which the base station allocates sub channels to the subscriber stations in its coverage area. The sub channels allocated to a subscriber station are shared by multiple con...

Customers arrive to a single service queue according to a Poisson process with rate l, from which they are routed to two parallel heterogeneous and exponential servers whose ra.tes are 1'1 > #2· Customers are released from the system after service completion, according to their arrival order a requirement introducing additional resequencing delays. Customers which are delayed due to resequencin...

Abstract We consider the notion of a constant length queue automaton —i.e., traditional with built-in limit on its queue—as formalism for representing regular languages. show that descriptional power automata greatly outperforms finite state automata, height pushdown and straight line programs expressions, by providing optimal exponential double-exponential size gaps. Moreover, we prove can be ...
