GitHub Issues and Pull Requests

Mitch Vars (MV) gave an overview of GitHub Issues and Pull requests and how they are used in the specification development process

GitHub Issue #145; Data Structure challenge.

Rick Neubauer (RN) from UMOJO described the issue in more detail. Spacial Data coming from IPS uses a 4 level hierarchy whereas CDS use 3 levels. CDS also includes some additional rules for how Areas are defined.
Jacob Malleau (JM) of CurbIQ described how CDS allows Areas to overlap which in theory would allow you to create a 4 lever hierarchy.
RN described the challenge of converting between the two but agreed that a change to the specification was not needed at this point.
KW Described system used by SFMTA. He did not see a need for a 4 lever hierarchy
James Barr (JB) of Turnstone suggested that IPS should be the one to adapt their data
Matt Davis (MD) of Populus agreed that this did not warrant a change and that additional layers could be used to contain these data.
Andrew Glass-Hasting (AGH) suggested requiring data in CDS from vendors to avoid these challenges.

GitHub Issue #146 Additional Fields for Computer Vision

RN described the need for additional fields to contain data related to computer vision like Vehicle Colors, License Plates, Camera Locations, Confidence Levels etc.
RN has attached PDF to the Issues with a detailed description of what he is proposing.
RN would like a limited set of predefined vehicle colors to avoid confusion when colors like "cinnamon mocha" come up.
RN agreed to create a PR based on what's in the PDF to move the proposal forward.
Michael Schnuerle (MS) asked that the PR be limited to items directly related to the computer vision issue and that other items be part of separate PRs

GitHub Issue #148 Standardized Naming Shemas for Zones

RN proposed a schema for creating zone names in the name filed in the Curbs API based on characteristics of the zone using the format STREET_BLOCK_DIRECTION_TYPE(s) where TYPE described the kind of zone in question, for example CLVZ for Commercial Vehicle Loading Zone.
RN also brought up the issues of defining curb colors used to display curb regs and how there's no consistency between vendors.
MV said that because of how the name field is defined any string value is acceptable so using this or any naming schema is currently allowed.
MV noted that he had opened a PR to a description field in addition to name but it may not be necessary
MS asked if a unique identifier field that's not a UUID could help in
MV and RN agreed that the description field was not necessary and that the PR would be closed.
RN will pursue the unique identifier issue

GitHub Issue #149 - Double parking events

RN suggests adding a Double Parking event type. Currently there's a PR (#164) that adds a double_parking event. RN described the need for separate start and stop events so that PR won't suffice.
JM suggested it would be best if there were separate event types for double_park_start and double_park_end.
MS said that could be linked by session ID. This would allow calculation of duration and connect it to a purpose, for example delivery, police etc
RN will open a PR, which will also add a center lane type. ...
