Resumen
A road environment-type (RET) detection function could improve the road awareness of inexperienced car drivers, especially in urban areas, and by doing so, it could slightly raise the urban traffic safety. A pragmatic implementation could make use of static road object data, e.g., traffic sign (TS) data, that is already collected and available on-board. It could rely on the TS recognition function offered by advanced driver assistance systems (ADAS). Furthermore, apart from its primary function, the RET detection system could provide reciprocal information?with respect to the current RET?for various ADAS and autonomous driving (AD) computations and subsystems. Making use of such reciprocal information could speed up the ADAS/AD computations, and render their results more accurate and more reliable, e.g., via introducing parameter constraints and marking regions-of-interest.
