Abstract

Estimation of road traffic is a fundamental problem which has been addressed with a variety of methods. In the present paper, a variant of the mobile observer method is proposed. It is assumed that some vehicles composing the road traffic are communicating vehicles. These communicating vehicles broadcast periodically beacon messages. The proposed method uses only these beacon messages as input data, and needs no additional equipment such as radar or GPS device in order to estimate the road traffic. The model is tested with the bi-directional simulation framework VEINS, which combines a microscopic road traffic simulator and a communication simulator. The preliminary results show the potential of the method and confirm the validity of the approach.
