Comprendre le trafic routier. Méthodes et calculs

Abstract : The high level of traffic demand, the significant number of players involved and the close-knit relationships between road networks make road traffic a complex area to study. Network congestion is an increasingly common phenomenon that is directly perceived by the general public, insofar as many users have personal experience of it. This explains why traffic theoreticians have been trying to gain a better, quantified understanding of the mechanisms in operation for the past 50 years or so. This publication aims to provide an accessible review of the subject at this point. Firstly, it sets out the different variables used to characterise the progress of vehicles along a thoroughfare, and secondly the fundamental relationships between some of these variables. By way of illustration, this is followed by a number of simple calculations for estimating the time taken to get through a traffic jam. The next section looks at the concepts of cumulative flows and journey times, whilst the last chapter deals with the problem of interconnected networks and calculations relating to spatio-temporal changes in congestion. Finally, there are a number of appendices, with a series of exercises and suggested answers, a French-English glossary and a bibliography. This publication is aimed primarily at professionals dealing with the problems of congestion, whether as operators of urban, suburban or interurban transport networks, or heading up research into the design of new infrastructure or improving the operation of existing infrastructure. It may also be of interest to undergraduate and Masters students, particularly those studying engineering.
