Lane Configuration Segment - woven-planet/opensafety-mbse GitHub Wiki

The California lane numbering scheme numbers Driving Lanes in a Conduit incrementally from 1 at the innermost lane toward the outermost lane (See Driving Lane Order in the Road Subsystem). The numbering may change if there is any reconfiguration of lanes. A newly forked innermost lane will become number 1 and cause all other Driving Lanes in the same Conduit to be incremented from the point where the Fork begins forward. So Driving Lane 1 will become 2 and so forth.

A Lane Configuration Segment marks the point where at least one lane reconfiguration begins. In the example above, the first Lane Configuration Segment may start at an Intersection exit and extend up until the beginning of the Fork reconfiguration. Then a new Lane Configuration Segment will start so that the lanes can be renumbered.

Lane Configuration Segments may not overlap so that each Driving Lane will have a unique number within each of its spanned Lane Configuration Segments.

When multiple reconfigurations occur in roughly the same longitudinal position, say a set of lane initiations at the exit of an Intersection, a single Lane Configuration Segment boundary will cover them all.
