Driving Lane Order

In California and many other places, it is customary to number Driving Lanes from a Conduit’s innermost Lane Division outward. So the innermost lane is 1 incrementing out to the Driving Lane along the outer Shoulder (if one exists). The numbering may change if Driving Lanes are reconfigured down the Road. Thus, a merge in the innermost Driving Lane will result in the elimination of that Driving Lane and decrementing the number of each Driving Lane to the outside.

Identifiers

1. Number + LCS + Road segment
2. Inside division + LCS + Road segment
3. Outside division + LCS + Road segment

I1: California lane numbers are unique within each Lane Configuration Segment (LCS). Each time the Lanes are reconfigured (merge, split, etc occurs) the numbering must be re-evaluated. The number of any given Driving Lane can change from LCS to LCS within the same Conduit.

I2, I3: Rather than using the California lane number, you can just use the ID of either the inner or outer Lane Division. You still have to combine it with the LCS and the Road segment since a given Lane Division can participate in more than one Lane as it spans Lane Configurations (merging, diverging, etc) and re-pairing to form other lanes.

Attributes

Number

In California, Driving Lanes are numbered sequentially, beginning with 1, from the innermost to outermost within a Conduit. Since there is no internationally accepted numbering method, this one is proposed.

Type: Driving Lane Number based on the Ordinal type (1, 2, …)
