This paper presents a day-to-day re-routing relaxation approach for traffic simulations. Starting from an initial planset for the routes, the route- based microsimulation is executed. The result of the microsimulation is fed into a re-router, which re-routes a certain percentage of all trips. This approach makes the traffic patterns in the microsimulation much more reasonable. Further, it is shown that the method described in this paper can lead to strong oscillations in the solutions.

However, the packets of a network use different routing protocols. A routing protocol is a combination of rules and procedures that lets routers informs each other of changes. It allows routers to share whatever they know about their neighborhood. Routing protocols are used to continuously update the routing tables that are consulted for forwarding and routing.

Agent-based model (ABM) simulation is a bottom–up approach that can describe the phenomena generated from actions and interactions within a multiagent system. An ABM is an improvement over model simulations which only describe the global behavior of a system. Therefore, it is an appropriate technology to analyze emergent phenomena in social sciences and complex adaptive systems such as vehicular traffic and pedestrian crowds. In this paper, a hybrid agent-based modeling framework designed to automate decision-making processes during traffic congestion is proposed. The model provides drivers wi

This method uses the prediction of router load by analyzing the fractal dimension of network traffic to reduce the probability of packet loss. It takes into account the predicted router load as one of the metrics for determining the shortest packet transmission routes in a computer network. Additionally, a computer simulation model of a computer network based on complex network theory, Markov processes, and fractal time series was created.

Les accidents routiers impliquant l’orignal engendrent des dégâts matériels coûteux et peuvent causer des pertes de vies humaines. Nous avons étudié le comportement de l’orignal près des routes afin de développer des mesures d’atténuation pour réduire le nombre d’accidents routiers avec cette espèce. Nous avons muni plusieurs orignaux de colliers GPS entre 2003 et 2006 dans le nord de la réserve faunique des Laurentides, où se trouvent deux routes principales asphaltées et un réseau de chemins forestiers. Les axes routiers, même les chemins forestiers où le trafic était faible, furent générale

Traffic congestion is a major challenge in modern urban areas, leading to increased travel time, fuel consumption, and environmental pollution. Traditional traffic control systems often rely on fixed signal timing, which lacks adaptability to dynamic traffic conditions. To overcome these limitations, the study proposes an Optimized Traffic Routing System for Urban Congestion Management that integrates multiple algorithms, including Fixed Cycle, Longest Queue First, Q-learning, and Search-Based Techniques which combines Genetic Algorithms and A Search* where Genetic Algorithm optimizes traffic

Reducing CO2 emissions is currently a key policy in most developed countries. In this article, we evaluate whether smart traffic lights can have a relevant role in reducing CO2 emissions in small cities, considering their specific traffic profiles. The research method is a quantitative modelling approach tested by computational simulation. We propose a novel microscopic traffic simulation framework, designed to simulate realistic vehicle kinematics and driver behaviour, and accurately estimate CO2 emissions. We also propose and evaluate a routing algorithm for smart traffic lights, specially d

Of all the methods available and the most appropriate modeling tools that meet their stated objectives for the study of traffic flows is a simulation. This article describes two methods for rapid routing traffic minibuses. For the method based on the analysis of the complete set of traffic situa-tions, developed a simulation model of municipal passenger transport. As a result of simulation ob-tained by the implementation of a process that allows after treatment to determine the value of sta-tistical criteria for defining the transport proce

In this paper, we consider IP fast recovery from single-link failures in a given network topology. The basic idea is to replace some existing routers with a designated switch. When a link fails, the affected router will send all the affected traffic to the designated switch (through pre-configured IP tunnels), which will deliver the affected traffic to its destination without using the failed link. The goal of the approach is to achieve faster failure recovery than traditional routing protocols that employ reactive computing upon link failures. Software-Defined Networking (SDN) switches can se

Network slicing is a technology that virtualizes a single infrastructure into multiple logical networks (called slices) where resources or virtualized functions can be flexibly configured by demands of applications to satisfy their quality of service (QoS) requirements. Generally, to provide the guaranteed QoS in applications, resources of slices are isolated. In wired networks, this resource isolation is enabled by allocating dedicated data bandwidths to slices. However, in wireless networks, resource isolation may be challenging because the interference between links affects the actual bandw

Software tools using computer simulations are frequently used in the research and optimization of railway transport systems. Such simulations serve to examine different railway traffic scenarios (which typically reflect different timetables and railway infrastructure configurations). During the simulation experiments, it is necessary, among other things, to solve tasks related to the determination of track routes along which individual trains or parts of train sets are moved. Many simulation tools require the basic and alternative permissible track routes to be manually specified before starti

Mobile ad hoc networks (MANETs) are characterized by the absence of centralized management and the lack of any infrastructures. The frequent topology changes and variable propagation conditions make a routing is the most important issue, therefore, it becomes necessary for nodes within the networks to use appropriate routing algorithms. In this paper, we evaluate the performance of AODV, DSR, OLSR and GRP routing protocols using OPNET modeler 14.5 simulation software. In the simulated mobile ad hoc network, we made all nodes receiving FTP traffic from a FTP server as common source. we increase

The innovative feature of this study is first to develop a methodology for designing advanced traffic surveillance systems based on microscopic traffic simulations. The developed methodology makes it possible ultimately to obtain algorithm structures and associated parameter values. The methodology consists of two main simulation experiments. The first experiment includes a parametric evaluation based on Monte Carlo simulation to identify the required performance of the surveillance system. The second experiment involves performing a microscopic traffic simulation with actual surveillance algo

Simulation of Urban Mobility (SUMO) is a powerful traffic simulation program which can work at different scales, from sub-microscopic to macroscopic. Depending on the available input dataset, it is possible to build lots of different configurations, changing routing and car-follow algorithms, and many parameters. Building a basic SUMO scenario is a multi-step activity involving the followings: preparing the transportation network, traffic definition, setting a routing algorithm, and running the simulation. The aim of the present work is to show a detailed real case study explaining how to buil
