A substantial portion of vehicular accidents occur at road intersections [1, 2]. Intersection control devices, stop signs and traffic signals, are used to increase safety and prevent intersection collisions.

The evolution of sensing technology and processing capabilities allows addressing the Intersection Collision Avoidance problem; yet, this technology is limited by its line-of-sight requirement. Location-aware technology (on-board digital map, GPS) helps to alleviate the line-of-sight-problem, but leads to increasing market costs of vehicles, thus rendering this technology inaccessible to the masses. Infrastructure-only approaches may represent an immediate solution to the problem; unfortunately, they are also limited by the inherent ineffectiveness of visual warnings.

Abstract
A substantial portion of vehicular accidents occur at road intersections [1, 2]. Intersection control devices, stop signs and traffic signals, are used to increase safety and prevent intersection collisions. Nevertheless, these costly and prone to failure devices can contribute to collisions. The evolution of sensing technology and processing capabilities allows addressing the Intersection Collision Avoidance problem; yet, this technology is limited by its line-of-sight requirement. Location-aware technology (on-board digital map, GPS) helps to alleviate the line-of-sight-problem, but leads to increasing market costs of vehicles, thus rendering this technology inaccessible to the masses. Infrastructure-only approaches may represent an immediate solution to the problem; unfortunately, they are also limited by the inherent ineffectiveness of visual warnings. Wireless technology could provide the missing link and give rise to a collaborative solution for the Intersection Collision problem, factually increasing safety and preventing deaths. This chapter gives an analysis of crash dynamics in road intersections and provides a survey of existing Intersection Collision Avoidance mechanism.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
