Abstract
A suitability determining system for establishing whether a road section is suitable for at least semi-autonomous vehicle driving is described. The system identifies a road section including at least one lane and delimited by at least one lateral road boundary, and derives from at least a first estimate providing vehicle a respective utilization direction estimate along with a corresponding respective detection confidence value for each of respective lanes detected by the estimate providing vehicle along the road section. The system determines a respective summarized direction utilization estimate along with a corresponding respective summarized confidence value for each respective detected lane, and determines an autonomous driving suitability indication applicable for the road section, which indicates the road section is suitable for at least semi-autonomous driving provided all determined summarized direction utilization estimates indicate equally directed utilization and all determined summarized confidence values exceed respective confidence thresholds.
