Traffic flow models have been applied to the study of pollution and to traffic management. The numerical implementation of the related physical models is a wide subject of study with far reached applications.
Our study is done by means of a second order model for traffic flow with which we can derive the average speed and acceleration of vehicles along a street. The model will be further applied to study the production of pollution. The aim is to exploit the speed and the acceleration of vehicles to estimate the production of NO_x, in particular that of NO_2, which are responsible for the increase of the ozone.
Traffic flow models are nowadays used to help the traffic management. In particular, the aim is the construction of a new second order model for traffic flow with two populations (for examples cars and trucks). In particular we are interested in simulating the creeping phenomenon, that is a traffic condition in which one of the two populations is congested while the other one is able to move, even if it is influenced by the congestion of the first population. Such a model, can be used to simulate different scenarios, based on the real condition of traffic, and to make the best decision to intervene and solve any problem.
