A method for automatically selecting a surveillance configuration for a road traffic area by sensor(s) among a set of configurations of at least one sensor, the set comprising at least two separate configurations, the road traffic area being segmented into M different regions with M≥1, at least one coverage area being associated with each sensor, the method being implemented by an electronic selection device, the method comprising:
- determining intersections between each region and each coverage area, respectively;
- and
- by using said intersections, computing an optimization of the optimal surveillance configuration corresponding to a sensor configuration or the combination of sensor configurations providing at least one maximal coverage,
- filtering the intersections obtained in the presence of intersection(s) whereof a surface, or a weighted surface, is below a predetermined threshold.
