Summary

0007789: [LanePosition] inconsistency in data element and ASN.1

Description

Email from Matthew Banks (Codha Wireless) 22 August 2018

In the V1.3.1 version of the CDD (https://www.etsi.org/deliver/etsi_ts/102800_102899/10289402/01.03.01_60/ts_10289402v010301p.pdf [^]) the meaning of ‘lanes’ has changed to be counted from inside (centre) rather than from outside (edge) and this has been reflected in some data elements. However for “A.40 DE_LanePosition”, then description says:

ASN.1 representation: LanePosition ::= INTEGER {offTheRoad(-1), innerHardShoulder(0), innermostDrivingLane(1), secondLaneFromInside(2), outterHardShoulder(14) } (-1..14)
Definition: This DE indicates the transversal position information on the road in resolution of lanes, counted from the inside border of the road for a given traffic direction. For example, the innermostDrivingLane corresponds to the left most lane of the carriageway in a country with right-land traffic, and to the right most lane of the carriageway in a left-land traffic (e.g. in UK). The value -1 denotes that the referenced position is outside the road.

But the ASN.1 (e.g. from %2Freleases%2FCDD_TS102894-2%2Fv1.3.1%2FITS-Container.asn [^]) is defined:

LanePosition::= INTEGER {offTheRoad(-1), hardShoulder(0),
outermostDrivingLane(1), secondLaneFromOutside(2)} (-1..14)

So there is confusion about the values for innermostDrivingLane.

I presume the ASN.1 is incorrect in this case?

Notes
(0015276) banksm (reporter) 30-10-2018 11:50	Also note that "outterHardShoulder" should be corrected to "outerHardShoulder"

(0015338) buburuzan (developer) 19-03-2019 13:38	This fix will be initially be integrated into the errata document of TC ITS as a correction for the version 1.3.1 of CDD document. ------------------------ Resolution: the description in A40 is the right one and the ASN.1 description in annex B shall be corrected accordingly. The version number of the container will not be increased due to this fix. Note: the solution will not be aligned with DATEX2 definitions. ------------------------
