The number of road vehicles significantly increased in recent decades. This trend accompanied a build-up of road infrastructure and development of various control systems to increase road traffic safety, road capacity and travel comfort. In traffic safety significant development has been made and today's systems more and more include cameras and computer vision methods. Cameras are used as part of the road infrastructure or in vehicles. In this paper a review on computer vision systems in vehicles from the stand point of traffic engineering is given. Safety problems of road vehicles are presented, current state of the art in-vehicle vision systems is described and open problems with future research directions are discussed.

The communication interface between the computers and the displays for Navy tactical systems has used Navy unique hardware and data transmission protocols. These unique hardware and software protocols limited the ability of these systems to support improved transmission capabilities such as multicast. In addition, certain new capabilities such as multiple radar displays and the use of graphical displays of maps were not possible. As part of the LHA Amphibious Assault Ship (General-Purpose) Display Upgrade program, the communication interface between the computers and the displays was changed to use a commercial Local Area Network (LAN) protocol. To enhance the data communication interface, the use of reliable unicast and reliable multicast were added. In addition, the display hardware was changed to use Commercial Offthe Shelf(C0TS) Unix workstations with Local Area Network (LAN) interfaces. These new Unix workstations would use emulation softwaye to provide the existing capabilities of the standard tactical displays while allowing the implementation of the new capabilities such as graphical color maps.
