This article deals with traffic data assimilation and algorithms that are able to predict the traffic flow on A road section. The traffic flow is modellized by the Aw-Rascle hyperbolic system. a functional has to be minimized whose optimization variables are initial condition. The Roe method is used to compute the solution to the traffic flow modelling system. Then the gradient of the functional has been computed by an adjoint method. This gradient will be used to optimize the functional.
