Editorial ITS and VMS

摘要

For many years, Intelligent Transportation Systems (ITS) have been promoted as an effective means to increase the safety and efficiency of the transportation network. One advanced transportation technology that has been widely adopted by many jurisdictions around the world is the Variable Message Sign (VMS). The intended purpose of most VMS systems is to display traffic related information to assist drivers in making informed choices about their travel routes and advise them of any delays in the traffic. They have been widely used in major expressways and arterials in many cities and are increasingly being deployed in work zones as well. The efficacy of providing traffic and other information has been a topic of constant debate. The papers in this special issue reexamined some of the research questions arising from the provision of information via ITS in general and VMS in particular.
