Modeling and Simulation of Urban Traffic Signals

Abstract: Traffic signals play a vital role in effective traffic management. In this paper we apply Arena simulation tool box for modeling and simulation of urban traffic signal system. It has been shown that Arena could be used in simulation of traffic signals system, despite the fact that Arena is not designed for modeling urban traffic signal control. We presented a non-trivial case study to illustrate how Arena is capable of modeling traffic systems.

In-line service measurements: an IPv6-based framework for traffic evaluation and network operations

Abstract: The ability to measure, monitor and control the service quality experienced by network traffic is becoming increasingly important as multiple traffic types are aggregated onto IP networks. Assessing the real-time performance of the application flows is an essential requirement for network operations and service management, as well as for identifying how the different traffic types and transports interact and behave, when they are carried over the end-to-end Internet infrastructure. This paper introduces a novel measurement technique for assessing the performance of IPv6 network flows. By exploiting IPv6 extension headers, measurement triggers and the instantaneous measurement indications are carried in the same packets as the payload data itself. providing a high level of probability that the behaviour of the real user traffic flows is being observed. The measurement mechanism is applied at the network layer and provides for a generic technique able to measure any type of traffic without depending on particular transports or on specific measurement architectures. A prototype implementation of this technique is also described and evaluated by measuring performance properties of application flows over different-capacity IPv6 environments. End-to-end delay and jitter of video streams have been measured, as well as the goodput for services operating on top of reliable transport. This measurement technique can be the basis for low-overhead, scalable, transparent and reliable measurement of individual and aggregate network flows, and can be dynamically deployed where and when required in a multi-service IP environment.

Methods for Division of Road Traffic Networks Focused on Load-Balancing

Abstract: The road traffic simulat ion is an important tool for analysis and control of road traffic networks. In order to be able to simu late very large traffic networks in a reasonable time, it is possible to use a d istributed computing environ ment. There, the co mbined power of mu ltiple interconnected computers is utilized. During the adaptation of the simulat ion for the distributed environment, it is necessary to divide the traffic network into sub-networks, which are then simulated on par- ticular nodes of the distributed computer. The load-balancing of the sub-networks and the communication between them are two key issues. In this paper, we compare the methods for traffic network division, wh ich we developed. The methods are focused on load-balancing and consist of two steps - assigning of weights to the traffic lanes and the marking of traffic lanes, which shall be div ided. For the first step, traffic simulat ions of different level of detail are utilized. For the second step, a modified breadth-first search algorith m or a genetic algorithm are utilized. The methods were thoroughly tested for their performance. Their description and the results of the tests are the main contributions of this paper.
