This paper aims to propose a new model to dynamicallyestimate speeds and relative distances of platoonedvehicles. State equations that describe time-dependentrelationship of vehicles’ speed and relative distance in theplatoon are modeled based on general conservation equations,whereas measurement equation consists of a conventionalcar-following model, computing acceleration rate fromrelative speed and spacing. A numerical analysis attemptedto estimate the speed and spacing of each vehicle in theplatoon indirectly from observation data such asacceleration rate of some of the platooned vehicles.Estimation precision and the model applicability werefinally discussed based on the results of numerical analysis.
