With our interest to reduce traffic congestion, simulations are necessary to investigate how to achieve this goal. Because of the difficulty of real-time experiments, traffic simulators are a good and widely used tool for analyzing specific situations of the traffic flow virtually. This paper introduces TraffSim, a new platform-independent framework, which is capable of simulating microscopic vehicular...
In the literature, the problems related to traffic and mobility management are typically addressed separately. However, the solutions to these problems—especially if based on vehicular ad hoc networks (VANETs)—are highly dependent, hence should be addressed jointly. Empirical studies demonstrate that improvements in traffic efficiency create latent travel demand. While lower tailpipe emissions and...
With the increased dissemination and computing power of mobile devices, it is now possible to execute distributed artificial intelligence applications for various situations: intelligent routing using algorithms, planning, distributed optimization of traffic lights. Our solution provides a complex way of integrating intelligent traffic simulation with a distributed traffic management system that is...
Traffic in densely populated regions increasingly suffers from congestion problems, to an extent which e.g. substantially affects predictable transport planning. Due to the highly dynamic character of congestion forming and dissolving, no static approach like shortest path finding, applied globally or individually in car navigators, is adequate here. In this paper we outline our current work on a...
This paper addresses the automated management and simulation of capacity problems for motor highway infrastructures, which often cannot keep up with traffic increases produced by, e.g., cars, motorbikes and trucks. Such kinds of problems require rather intelligent highway infrastructure management with strategies with, often, contradictory goals: On the one hand side, individual drivers would like...
Because of the shortcomings existed in traditional node-link model, this paper presents a lane-based network model. The objective of the model is minimizing the whole evacuate cost, and the constraint conditions are eliminating crossing-conflicts, reducing confluence, flow conservation and non-negative, restricting the traffic capacity of the nodes as well as arcs, and so on. The model is aimed to...
