The Parameters Analysis for the Intersection Collision Avoidance Systems Based on Radar Sensors
This paper mainly studies the analyses of parameters
in the intersection collision avoidance (ICA) system based on the radar
sensors. The parameters include the positioning errors, the repeat
period of the radar sensor, the conditions of potential collisions of two
cross-path vehicles, etc. The analyses of the parameters can provide
the requirements, limitations, or specifications of this ICA system. In
these analyses, the positioning errors will be increased as the measured
vehicle approach the intersection. In addition, it is not necessary to
implement the radar sensor in higher position since the positioning
sensitivities become serious as the height of the radar sensor increases.
A concept of the safety buffer distances for front and rear of the
measured vehicle is also proposed. The conditions for potential
collisions of two cross-path vehicles are also presented to facilitate the
