Originally published in 1973 and based on papers published in The International Journal of Environmental Studies, this book discusses the impact of road vehicles on the environment. Particular stress is laid on the design of towns and vehicles, economic problems associated with these, the responsibility of planners and the integration of transport planning and environmental planning at local, regional and national levels. Subsequent sections cover the science of accident research and legislation, particularly dealing with global pollution control. Many of the problems discussed remain as pressing today as when this book was first published.

The interest in the mathematical modeling of transportation systems stems from the need to predict how people might make use of new or improved transport infrastruc ture in order to evaluate the benefit of the required investments. To this end it is necessary to build models of the demand for transportation and models that de termine the way in which people who travel use the transportation network. If such models may be constructed and their validity reasonably assured, then the predic tion of the traffic flows on future and present transportation links may be carried out by simulating future situations and then evaluating the potential benefits of alternative improvement projects. In the attempts that were made to construct mathematical models of transportation networks, the notion of equilibrium plays a central role. Suppose that the demand for transportation, that is, the number of trips that occur between the - rious origins and destinations is known. Then it is necessary to determine how these trips are attracted to the alternative routes available between origins and destinations. Knight (1924), gave a simple and intuitively clear description of the behaviour of road traffic under conditions of congestion.
