This working paper is a preliminary review of the state of the art in the study of the economics of traffic information. The focus is on the different methods used to model the decision process of drivers in a traffic system, and on the effect of traffic information on this process. In addition, the review includes the characterization of information in terms of content and accuracy. The purpose is to develop an understanding of the market for different types of traffic information. The paper also includes some preliminary models that can be used to model the demand and supply of traffic information, including its temporal and spatial characteristics.
