Similar traffic corresponding to the actual usage should be generated when doing the test or simulation for the network reliability. However, in the test or simulation for a large scale network, it is very difficult to generate the realistic network traffic, because it is complex and time-consuming to generate different traffic flows corresponding to businesses in the actual usage of the networ...

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 ...

This paper focuses on the differences between monofractal and multifractal network traffic, both in terms of modeling approaches, and in terms of practical impacts on network performance. Empirical traffic traces are used in the parameterization and evaluation of traffic models. Simulation is used to evaluate the performance differences between monofractal and multifractal traffic, both for ind...

Traffic generators have been essential for representing realworld traffic in network simulation studies. Furthermore, Internet-like traffic is a necessity when analysing the impact of different kinds of traffic on the network. In this paper, we present the implementation details of our HTTP traffic generator in the ns-3 network simulator. It is able to generate Internet-like as well as user-def...

Many traffic simulation software packages are available to help traffic engineers and researchers study and evaluate the potential impact of proposed traffic management strategies and policies. However, existing tools require a significant investment in time for learning how to create models, perform calibrations and finally analyze the results. This substantial learning curve severely restrict...

In this paper, we present a cyclically time-expanded network model for simultaneous optimization of traffic assignment and traffic signal parameters, in particular offsets, split times, and phase orders. Since travel times are of great importance for developing realistic solutions for traffic assignment and traffic signal coordination in urban road networks, we perform an extensive analysis of ...

Hybrid traffic modeling and simulation provide an important way to represent and evaluate large-scale traffic networks at different levels of details. The first level, called “microscopic” allows the description of individual vehicles and their interactions as well as the study of driver’s individual behavior. The second, based on the analogy with fluidic dynamic, is the “macroscopic” one and p...

The paper deals with simulation of congested road networks through dynamic traffic assignment models and presents a new quasi-dynamic traffic assignment model that improves realism and effectiveness of both usual static traffic assignment models and other quasi-dynamic models recently introduced in the literature, as it simulates flow progression onto the network by moving link flows according ...

The introduction of methods from statistical physics for traffic flow modelling, such as cellular automata models, enabled the faster than real time simulation of large traffic networks. A key issue faced by such efforts is the expandability of the network model. This paper discusses the development of a cellular automata framework for micro-simulation of vehicle traffic flow in road networks a...
