A rapid growth of the Internet and proliferation of new multimedia applications lead to demands of high speed and broadband network technologies. Routers are also necessary to follow up the growth of link bandwidths. From this reason, there have been many researches on high speed routers having switching capabilities. To have an expected effect, however, a control parameters set based on traffi...

Synthetic mobility models can be used to simulate the movement of a traffic unit or a group of traffic units in a telecommunication network. Characteristics of pedestrian and vehicular traffic, such as speed-flow, speed-density and flow density are often neglected in current synthetic mobility models. The analysis, emulation and simulation of telecommunication networks with mobile users using m...

Grid traffic characteristics are quite different from that of normal Internet traffic, as they impose more stringent constraints (such as packet delay and flow deadlines) on network resources. This paper explores differentiated channel provisioning in grid network, in order to schedule bulk data traffic. We propose a solution based on the two-phase routing scheme to provision the virtual channe...

The Highway Capacity Manual (HCM, 1985) has defined level of service mostly for the developed countries having predominant contribution of motorized vehicles. There are very fewer number of models to simulate the urban heterogeneous traffic flow having significant proportion of non-motorized vehicles. These types of flows are mostly observed in the countries of Asia-Pacific region. The flow of ...

A number of key areas in IP network engineering, management and surveillance greatly benefit from the ability to dynamically identify traffic flows according to the applications responsible for their creation. Currently such classifications rely on selected packet header fields (e.g. destination port) or application layer protocol decoding. These methods have a number of shortfalls e.g. many ap...

Snowy weather will significantly degrade expressway operations, reduce service levels, and increase driving difficulty. Furthermore, the impact of snow varies in different types of roads, diverse cities, and snow densities due to different driving behavior. Traffic flow parameters are essential to decide what should be appropriate for weather-related traffic management and control strategies. T...

Pedestrians' road-crossing behavior can often interrupt traffic flow and cause vehicles queueing. In this paper, we propose some moving rules for modeling the interaction of vehicles and pedestrians. The modified visual angle car-following model is presented for the movement of vehicles with consideration of the lateral effect of waiting pedestrians. The pedestrians' behavior is summarized as c...

The characteristics of traffic flows on signalized arterials are examined within a cellular automata micro-simulation model. The model is used to analyze arterial throughput and travel times for given densities, coordination schemes and signal spacings. A fundamental 3-D relationship between flow, density and offsets for signalized arterials is established. It is shown, in particular, that arte...

In traffic engineering to effectively distribute traffic flows over multiple network paths, taking into account traffic characteristics for individual flows is vital in appropriately assigning flows to network paths for achieving better delay performance of the total traffic. All flows assigned to a path, in which some flows are heavily bursty, equally experience a significant queuing delay whe...

As traffic demand on road networks steadily increases every year, the need for alleviation of global congestion arises. Our contribution lies in assisting of traffic engineers and policy makers who are faced with the problem of controlling the traffic flows. In this paper, we explore the usefulness of cellular automata to traffic flow modeling. We extend some of the existing CA models to captur...
