Rich-

1) This should be possible. I just have to find some time to import those crashes.

2) You can almost do this now. If you click "Persons Injured" or "Persons Killed" it will change the chart on the bottom. But you can only select one right now. I can probably get it working where you can make multiple selections.

3) See above; selecting something on the left will filter the map. 

4) It is using realtime data and ill look into that CB7 count, but it's also kind of at the whim of whats in the dataset. If there's no location specified then it doesn't get mapped and doesn't get added to the counts.

5) Intersection counts should be pretty easy to add. I'm also going to add time of day and probably add the factors back in.

6) An option to look at the data monthly is in the works.

7) Yeah that pop up ahaha, so it's showing the details of a single crash. If you click on one of the ones listed below it will show the details for that crash. 

Thanks for the great feedback!

This is awesome!!

A few suggestions / questions for the "more info" view....

- I know the crash data site only has the previous 24 months of data. Is there a way for you to do a hybrid so that it retains data from 25+ months ago so that it can have the complete year for two years ago as well as real-time data?

- I'd love to see an additional option to create a chart showing crashes causing injury / death for the monthly trending chart on the bottom.

- Similarly, I'd love to see an option to map only crashes causing injury / death as well as to create a map that shows total crashes and crashes causing injury / death.

- Is this using real-time data? I'm seeing that there's a sharp drop in crashes in Manhattan CB7 in July and I'm wondering if this is because it's only a partial month's worth of data? (The month is 90%+ over so if it's real-time, that wouldn't explain all of the drop.)

- It would be great to have a chart for each filtered area (such as community board) showing the intersections with the highest number of crashes.

- The chart showing crashes / year doesn't allow year over year comparisons, as it has only partial data for 2012 and 2014. Perhaps add an option to show monthly averages rather than annual totals?

- On the main view, when I click on Manhattan CB7 and click on the circle at 97th / West End, it shows 0 injured / killed up top of the pop up list. But if I scroll down the list of crashes, it lists 2 crashes with injuries.

Hi y'all,

I've been busy finding an apartment and moving but I finally got an update to this site out.

If you load:

You can look at City Council Districts, Community Board Districts, Neighborhoods, Police Precincts, and Zip Codes in a more detailed fashion. I tried to incorporate a lot of the feedback from the list in this page. It's still rough design / ux wise but I'd like to get some feedback as to how it can further be improved. 

Thanks,

Akil

A bit off topic, but possibly relevant to this thread: Does anyone have any 'official' report on how representative the NYPD data is in terms of actual total number of collision events? I know this represents (all?) of the NYPD reported events, but many events go unreported for various reasons... are there any estimates as to what percentage of all events the NYPD data actually represents? A report or just intuition would be useful initially? I'll probably bring this up at the next hacknight as well...

Cheers,

Carson

This is great!

a few first blush ideas:
 1. Add City Council, PD, and Community Board districts. It would be great to start advertising to City Council members and Community Boards that they have another Vision Zero tool.
 2. You should have an email address or some type of device that advertises who you are and that you are looking for suggestions. Maybe, this could be on the about page?
 3. On the about page, link off to the City's Vision Zero map and ask visitors to map their dangerous intersections. < http://visionzero.herokuapp.com >.
 4. If you have a write up on using the data, problems with the data, or another data insights, you should post that to this map.
 5. I would love to be able to go though time and see years or months. I know that is a more difficult request. 

Keep up the good work.

Hey yinz,

I've been messing around with the motor vehicle collision dataset and I just made live an updated dashboard.

You can filter accidents by contributing factor, injuries or deaths, and do some geographic filtering by police precinct, zip code, neighborhood, and community board. (under map controls)

(This filtering is pretty rough right now it's just returning the accidents that fit in a large bounding box then narrowing them down by what intersects the shape, but this could be incorrect for precincts depending on if the accident falls on the border of two precincts there's no way to tell in the data provided which precinct actually got the call.)

Each accident is clickable and you should see a popup with additional details for the accident.

I'd love to get some feedback from you guys as to how this could be extended even more.

You can check it out here:
