This thesis describes two different methods for the control of traffic flow, the car-following model and the bilateral control model, and presents an analysis of their stability. The mathematical models that describes them can be written as systems of homogeneous linear differential equations and their stability analysed by studying their eigenvalues and eigenvectors. We will discuss a general case, with an infinite number of vehicles, and some boundary traffic conditions. We will then further substantiate the theoretical claims with computer simulations.
