There has been tremendous progress in algorithmic methods for computing driving directions on road networks. Most of that work focuses on time-independent route planning, where it is assumed that the cost on each arc is constant per query. In practice, the current traffic situation significantly influences the travel time on large parts of the road network, and it changes over the day. One can ...

Maritime situation awareness is of importance in a lot of areas – e.g. detection of weapon smuggling in military peacekeeping operations, and harbor traffic control missions for the coast guard. In this paper, we have combined the use of Self Organizing Maps with Gaussian Mixture Models, in order to enable situation awareness by detecting deviations from normal behavior in an unsupervised way. ...

Abstract The CODAR System is a simulation and visualization toolbox for vehicle-to-vehicle communication. In this paper, we introduce the visualization component, the CODAR Viewer, as context information display. It visualizes communication, creates awareness and provides situation information. Visualized vehicle-to-x (V2X) communication data provides additional information, increasing safety a...

Aerodrome ground traffic management consists of many processes. Their complexity causes that telematic solutions intended to assist both the air traffic controller who coordinates taxiing and the pilot who executes them are introduced. An example of such a solution is A-SMGCS system. At the moment, intensive research on advanced system functions are carried out. They include smart taxi route ch...

Abstrucf-Self-similar traffic is distinguished by positive correlation, which can be exploited for better traffic management. Inspired hy measurement-based admission control schemes, a measurement-based congestion alarm is proposed. The aggregate traffic at an output port of a switch or router in a high-speed network is modeled by a fractional Gaussian noise process. Traffic measurements are pe...

An important aspect in management of IP networks is to control traffic traversing links on the network, while optimizing performance. Using offline approaches, this means that recomputation should be carried out on a periodical basis to adjust network configuration to the most actual traffic situation obtained from measurements or forecasts. In this work we investigate the effect of partial dem...

In this paper, the author quantified the city traffic environment carrying capacity on the basis of the relationships among traffic environment carrying capacity、the bearing capacity of the urban traffic and urban environmental capacity. And based on the actual vehicle maintain models of Jinan city, the author adjusted the formula of motor vehicle exhaust emission source ,then fixed the OPSM st...

OBJECTIVE To instruct children and teenagers about safe transportation and about their behavior as cyclists and pedestrians. SOURCES OF DATA The MEDLINE and LILACS databases were searched, using the following terms, from 1995 to 2005: traffic accidents, child, adolescent, morbidity, mortality, age, and gender. Scientific articles on morbidity and mortality from traffic accidents, children in ...

One of the ways to overcome traffic problems in large cities is through the development of an intelligent monitoring and control of traffic lights system. This paper addresses the design and implementation of an intelligent traffic lights controller based on fuzzy logic technology. A software has been developed to simulate the situation of an isolated traffic junction based on this technology. ...

This paper presents the application of fuzzy-neuroevolutionary hybrid system with online reinforcement learning for intelligent road traffic management and control. Taking a step away from the conventional traffic control system, the hybrid system presents different methodologies in knowledge acquisition, decisionmaking, learning and goal formulation with the use of a three-layered hierarchical...
