Vehicle Navigation System

The paper proposes a vehicle flux estimator, based on Received Signal Strength Indicator measurements in order to prevent the road traffic congestions. Successive RSSI intensity determinations and the corresponding time values were used to estimate the vehicle flux in various conditions. A hierarchical network model, including a simulation module and experimental data, was implemented. In order to estimate the current traffic state, a new strategy in which a special attention was given to information collected from the converging streets near the main crossroads was elaborated. The updated information was used by a road traffic simulator in order to improve the traffic flow. The proposed solution could contribute to the improvement of the performances obtained using other existing traffic control and monitoring systems.
