Fundamentals of Traffic Dynamics
Traffic flow theory is devoted to study the interactions between vehicles (or drivers) and the infrastructure, which is given by many components, such as the roadways, the road signs and the traffic control ac...

Chapter
Second-Order Macroscopic Traffic Models
Second-order macroscopic traffic flow models introduce a second dynamic equation compared to first-order models, i.e. the equation describing the dynamics of the mean speed of vehicles. Second-order models wer...

Chapter
Emission Models for Freeway Traffic Systems
It is widely recognised that road transport is one of the main sources of air pollution and that the measures to reduce pollution need to accurately take into account the contribution of road traffic systems. ...

Chapter
An Overview of Traffic Control Schemes for Freeway Systems
Some of the criticalities associated with traffic phenomena in freeway networks can be mitigated or even eliminated with suitable control strategies. The most important and evident drawback of traffic is surel...

Chapter
First-Order Macroscopic Traffic Models
Macroscopic traffic describe the traffic behaviour at a high level of aggregation, i.e. the traffic dynamics is expressed through aggregate variables, such as traffic density, mean speed and flow. Macroscopi...

Chapter
Microscopic and Mesoscopic Traffic Models
Besides macroscopic traffic flow models, traffic modelling in freeway systems has also been treated with other general approaches, resulting in microscopic and mesoscopic models. Macroscopic models can surely ...

Chapter
State Estimation in Freeway Traffic Systems
Freeway networks are generally equipped with different types of sensors which are able to measure traffic conditions in real time. Such sensors are placed in fixed positions on the road network and, hence, mea...
