13.1 Introduction

This chapter covers traffic management systems (TMS), one of the most important components of modern ITS. The main motivation for traffic management is the efficient management of a road network, optimizing the traffic flow while maximizing road users’ safety and comfort. These systems involve several stakeholders but are mainly directed towards road users, helping them act efficiently and safely whilst on the road. This goal is achieved through different applications and services, by communicating, analysing and sharing information.

We start this chapter with the definition of a ‘traffic management system’, followed by a depiction of different traffic environments on which traffic management systems operate. Afterwards, a proposal for a conceptual framework of traffic management systems is presented, on which data collection (inputs), data processing and analysis (platform) and information dissemination and actuation (outputs) are established as the pillars for a TMS.

Although ITS involve multiple transport modes, the focus for this chapter will be brought on roads. Throughout the text, Traffic Management Centres (TMC) and Traffic Control Centres (TCC) will be referred to – although being very similar in meaning, the first term refers to a more generic management facility, whereas the second will usually refer to actual control centres ...
