| Summary | 0007295: [DE_ClosedLanes]: make drivingLaneStatus OPTIONAL | ||||||||
| Description | Motivation: Quote from CDD TS 102 894-2, page 88: ClosedLanes ::= SEQUENCE { hardShoulderStatus HardShoulderStatus OPTIONAL, drivingLaneStatus DrivingLaneStatus, ... } If there is information available about the status of the hardshoulder, but no information regarding the driving lanes, the information for “hardShoulderstatus” cannot be transmitted, since “drivingLaneStatus” is not optional. Consequence The actual definition of “ClosedLanes” does not allow to transmit valid information about the hard shoulder status while not knowing the actual road layout – or forces the sender to guess and take the risk of giving false information about the number/status of driving lanes. Example #1 In some roadworks configurations a closed hardshoulder can be identified by a roadworks trailer (by recognising certain sign configurations on the trailer), even without connection to a backend system and without knowing the lane configuration. This information cannot be transmitted in the structure of “ClosedLanes” as it is defined now. As a matter of fact : Not wanting to give false informaion or to use a shady workaround, some information, although available, will not be transmitted in roadworks DENMS, just because it is not allowed to code “ClosedLanes” in a DENM with “hardShoulderstatus” alone. Example 0000002 A broken down vehicle on a motorway might have detected that it is standing on the hard shoulder (e.g. by recognising the thick continous lane marking is located to its left), but it is not possible to convey this information to other vehicles without guessing the remaining road layout (which at this point in time might differ from the static information the car might have on its navigation device). Again, available information is not transmitted, because it is not allowed to code “ClosedLanes” in a DENM with “hardShoulderstatus” alone – or wrong information might be transmitted about the number of driving lanes and/or their status. Proposed Change: “drivingLaneStatus” should become an optional element in the Sequence “ClosedLanes”. This way information only concerning the hard shoulder can be transmitted, even if the status of the driving lanes is not known or not effected at all. | ||||||||

this would break the backward compatibility, in this case, the protocol version number should be increased to 2, in case the present data frame is used by CAM or DENM or any other facilities basic service. |

please approve at ITSWG1#35 |
|
(0013917) Sebastian Muellers (administrator) 04-04-2016 16:37 |
this change is not backward compatibile and requires an update of CDD version to V2 |
|
(0013932) linla (manager) 12-04-2016 13:42 |
approved in ITS WG1#35 meeting, make it OPTIONAL. |
|
(0013938) linla (manager) 12-04-2016 14:17 |
if we accept the follwing change: DrivingLaneStatus ::= BIT STRING { } (SIZE (1..14)) text: bit 0: reserved and shall be set to 0 by default. bit 1: outerMostLane bit 2: secondLaneFromOutMostLane ... then there is no need to set it to OPTIOANL, because it is sufficient to send a one bit value (bit 0 set to 0) please consider this and provide feedback to WG1. |
|
(0013952) Sebastian Muellers (administrator) 04-05-2016 09:26 |
Please implement ClosedLanes ::= SEQUENCE { hardShoulderStatus HardShoulderStatus OPTIONAL, drivingLaneStatus DrivingLaneStatus OPTIONAL, ... } |
