Microscopic Simulation of Optimal Use of Communication Network

Abstract

The development of transportation in Slovakia has an increasing character as in the other developed countries, and the negative impacts of transport are still rising. To handle this situation, the Slovak cities should have to solve their transport situations with more often use of ITS elements. One of the possibilities of optimal communication network use in the city is the management of traffic flow on the route, or its reroute from congested stretches to existing alternative routes of transport network. This use is suitable, if the likelihood of overloading is high, and the lateral routes have a sufficient reserve. High proportion of transport which is possible to reroute is a condition for success of this system. In our article we build a cost- benefit based model to compare two variants. The first variant includes a current state and in the second one designed changes will be incorporated. We use this model to solve the problems on communication network in the city of Žilina. As a modelling tool we use software Aimsun which allows a microscopic simulation. AIMSUN (Advanced Interactive Microscopic Simulator for Urban and Non-Urban Networks) is a software tool which is able to reproduce real traffic conditions on any network. It means that we can also use it to predict behaviour of network with implementation of vehicle guidance systems.
