摘要

Optimization of traffic on a large public road network is an undertaking and complex task.rnReversible Direction Lane theory is an interesting and special method within this subject. Thisrncan completely support the fluctuation or alteration in existing congestional direction ofrntraffic dynamics (time of day, seasonal, etc.) on existing road surfaces. In such case certainrnsubsystems of the main network cease to exist, and subsystems working with new connectionsrntake their place. This type of routing therefore changes the system’s structure ?in an optimalrndirection”, but many practical and safety questions arise. A number of studies prove that inrnareas this method is employed, travel time decreased by 30-40%, waiting time by 40-50%,rnnumber of stops by 30-40% compared to previous data. Its benefits were also shown in fuelrnconsumption reduced by 15-25%, harmful substance emission HC by 15-25%, CO by 3-5%,rnand NO by 8-10%. We may not leave the application of this opportunity out of considerationrnin a case when a country's road infrastructure demands considerable developments otherwise.rnWe examine the modelling of reversible lane system configured on a road part network. Thernfunctions of the each network's elements and contacts between its each element cease in therncourse of a change and new contacts and new function elements are activated instead of them.rnThis opens the door to a new principled optimal control, which happens to the dynamicrnchange of the structure of the network graph. In the model, as in reality, the geometryrnelements do not disappear naturally, but create a variable network as a result of their newrnfunction and their connection system. The article presents the mathematical modeling of thernproblem. Points out the fundamental questions of the structure change and exemplifies thernabove on a simple example. We examined a general mathematical model describing thernReversible Lane System. Our descriptive mathematical network model is a positive non-linearrndynamic system, and also important that it is a macroscopic model. The function of everyrnelement and the contacts between the elements cease in case of direction change in any part ofrnthe network, then new contacts and new functional elements are activated. We examined thernavailability of the optimal control in a sample network depending on the traffic density, usingrna new principle, which responses to the dynamic change of the structure of the network graph.rnIt can be shown, that the results from our model are in harmony with the real traffic valuesrnbased on measurements made in road traffic systems working with Reversible Lane System,rnincluded in our literature references.
