OpenXC Sample Data Feedback

I'll probably post this on the Google Group too, but thought I would get some feedback here.

Is it just me or are the variables measured way too frequently? I've got the data in Excel to play around with and some of the sheets are over 120,000 cells long. It's making it pretty tedious and time consuming to do anything since it takes so long to just manage the data.

Why would anyone need some of these variables at 10Hz frequency? 1Hz is probably overkill for the majority of them. A 45 minute drive will give you 27,000 data points for one variable at 10Hz.

Also, the 17 sample files/traces aren't very helpful. There's no real context for what the file is representing besides a brief name and maybe a very short description. 17 samples isn't enough if you're looking to do any type of aggregation either. Additionally, as someone pointed out, none of them are for London even though this is a ChallengePost specifically for London traffic.

Just wondering what other people's thoughts were on all of this. Hopefully the judges will also realize the shortfall of the sample data and look more at the other content.

    Hi szsherman,

    Thank you so much for the feedback. Please feel free to post this feedback in the OpenXC Google Group as well - which is closely monitored by the OpenXC team.

    I do want to be clear that, while using OpenXC data is encouraged, it is not required. Additionally, the judging criteria does not include evaluating the integration of any specific dataset, including OpenXC.

    As a reminder, the judging criteria are:

    1) Quality of the Idea: Includes creativity and originality of the idea.
    2) Implementation of the Idea: Includes how well the idea was executed by the developer.
    3) Potential Impact: Includes the potential impact and value provided to London drivers, pedestrians, and residents.

    I hope this information is helpful to you and I wish you the best of luck in the competition!

    Best,
    Serena

    Thanks, Serena, always good to be reminded of the exact criteria.

    For everyone else - who all is working with OpenXC and its sample data for this challenge? What has been your experience with it so far?
