- nkoren 2y agoSame, from the UK.
- Zak 2y agoThe problem I'm seeing is that when I move or resize the map, it makes requests to *.tile.openstreetmap.org, but not to roadway.report/accidents_by_location_geojson. I checked with desktop Firefox and Chrome.

- jfoutz 2y agoInteresting. At the moment it's very very slow. I was able to eventually load and click through to see broad details about a crash. Pretty impressive collection of data.
- 38 2y ago[flagged]
- xyst 2y agoalready hn dos’d edit: while u fix it, what’s the source of the data? Did you get it from all of the state DoTs or is there a single set from the fed?
- Bencarneiro 2y agoIt's all from the FARS database
- hm-nah 2y agoAlso curious of data source.
- Bencarneiro 2y agoNhtsa FARS
- massung 2y agoThis is great! Plans for any filters? For example, I can see the death in front of my house from a year ago, which was the driver suffering a heart attack while driving. He was the only victim and it wasn’t the crash that killed home. Would love to be able to compare areas for things like: - DUI - speeding/reckless driving - cycling victims - pedestrian victims - multiple vs single vehicle - medical cause
- akira2501 2y agoI high recommend people get into NHTSA's FARS database. It's an old school GSA type database, so it's format is a little unusual, but you can hoist into an SQL table without much difficulty, and then you can ask and answer all of these questions. They often include things like "path of accident" so you can even run queries and ask questions like "how many vehicles flipped over before crashing" or "how many passengers get ejected from the vehicle before dying" or even "how often are snow banks involved in crashes?" Odd things last I checked in 2015: More people die in Texas than California. In total. Not per capita. Most people in Florida die between 7pm and 9pm which is far later than most other states. Pedestrians usually die at night. Anyways, a great database last I used it: https://www.nhtsa.gov/research-data/fatality-analysis-reporting-system-fars https://www.nhtsa.gov/research-data/fatality-analysis-report...
- bigtoe416 2y agoI used to be a volunteer firefighter and I see some of the fatalities (but not all) on this map. Looking at one of them some of the information is quite accurate (type of accident, what caused it, age of person) while other information is not at all accurate (number of people in the car, if a seatbelt was in use). It's curious how some fairly important pieces of data can be quite wrong.

- imoverclocked 2y agoYeah, according to certain studies, most of my 6th grade class has stinky cheese farts and did moderate to heavy cocaine use in the morning.
- hahahacorn 2y agoRather morbid, but I'm trying to find details for my 24 year old cousin who was struck and killed by a drunk driver in 2008(?). Somewhere in Texas. Any plans to add search/filter functionality?
- Bencarneiro 2y agoThe best I have right now is place and time to find a specific incident, but yes I should be able to get some basic filters up soon
- davidw 2y agoLooks like where I live, deaths are more closely associated with big, wide, fast roads. It's ironic that drivers get frustrated by smaller, narrower streets as not feeling very safe, but that uncomfortable feeling 1) slows people down and 2) keeps them on their toes in terms of looking out for hazards rather than feeling ok with driving fast and not paying as much attention.
- Davidzheng 2y agoAre you weighing the deaths by use of the road. Otherwise it's not representative of danger level right
- tstrimple 2y agoTo me the comment spoke to our criminal lack of intelligent road design. It’s well known through multiple studies that road design impacts how fast people drive far more than posted speed limit signs. If we actually cared about road safety, we would design roads to be more safe and not just design a road that is comfortable to drive 60mph on and put up a 25mph speed limit. When you want slower speeds you need to make lanes more narrow. Add obstacles along the side of the road so it doesn’t feel so open. Add medians as areas where pedestrians have a refuge when daring to cross a place designed for vehicles. Add chicanes and bollards to force speed compliance in especially dangerous areas. There seems to be almost none of this happening in most places in the US that I have visited.
- thefaux 2y agoWe also could largely solve this problem with technological enforcement but people really hate that. If we made both the financial penalties for speeding and the probability of being caught sufficiently high, we could practically eliminate it overnight.
- WarOnPrivacy 2y ago> We also could largely solve this problem with technological enforcement but people really hate that. The challenge in giving powerful entities direct control over our actions is they: directly control our actions, ceaselessly seek to control other actions, will be as unaccountable as they can be, will not ever allow control to flow in the other direction.
- keepupgudwrk 2y agoWhat was your toolset for the analysis? Can’t see now because of HOD? Excited to see your data! I haven’t seen it yet but I imagine this is will be similar to the private actuarial structured data of a any car insurance company. By no means am I diminishing your efforts.
- jppope 2y agoThis is one of the most amazing things I've ever seen on Hacker News. Great work whoever did this!
- Bencarneiro 2y agoLol ok I'm trying to get home and figure out why it's server error city (yikes)
- WarOnPrivacy 2y agoWe appreciate your diligence. Please enjoy complimentary load death. Would you like that mapped?
- ProAm 2y agoIs it hugged to death? All I see is a background image on FF and Vivaldi?
- liminalmilenial 2y agoMust be hug of death. Anyway, I recently made a video visualization of every fatal accident in 2022 by timeline and it ended up being over 8 minutes long because there were so many (over 39,000 events). It's sobering to realize how many people are losing their lives on the roadways each year. There's a fatal crash about every 10 to 15 minutes in the US alone.
- kart23 2y agoYou can also query the database pretty easily here if the site isn't loading: https://cdan.dot.gov/query https://cdan.dot.gov/query
- zippergz 2y agoI get an error from that site too ("reporting engine is down!"). Is the site posted here directly querying the DOT database and knocking it offline, or just a coincidence?

- lukasb 2y agoNot loading right now, but if it doesn't already include it, would love to see this data normalized by the amount of vehicle traffic each location has, to get a better sense for which locations are dangerous vs just busy.
- Karrot_Kream 2y agoI don't think that's right. We shouldn't think of death in terms of "deaths per mile" because human costs aren't amortized per mile. Every death is a death. Killing someone then driving in circles shouldn't make you a less dangerous driver.
- mizzao 2y agoI don't think it should be thought of as "deaths per mile" but rather "deaths per car passing by" which allows one to compare the relative danger of driving in different locations.
- Karrot_Kream 2y agoThis implies that the only road users are cars and that vehicle volume is fixed. Factors like vehicle speed, modal mix, lane widths, and parking geometry all affect the safety profile of a street. "Cars passing by" is too lossy a metric to be relevant. Decreasing vehicle volume is always an option.
- deleted 2y ago[deleted]
- fastball 2y agoIt is definitely not too lossy to be valuable. Imagine a town that has 100 cars in it and 10 traffic deaths per year vs a town that has 10,000 cars in it and also 10 traffic deaths per year. Both towns have the same population. Without any sort of normalization the towns look the same, but clearly very different things are going on in those scenarios and a per mile or per car or whatnot will help you identify that. Obviously it doesn't give you any sort of root cause but it is an indicator that a deeper investigation is needed.
- dheera 2y agoIs there a clean database of all accidents, not just fatalities, that can be downloaded?
- Bencarneiro 2y agoI need to look into something called NEMSIS, but no not to my knowledge. Most states have injury records though.
- mikeocool 2y agoHey — this is really cool — though looks like it’s being hugged to death right now. Assuming the data is being updated less often than hourly it should be relatively straight forward to generate a pmtiles tileset of the accident points, using either tippecanoe or planetiler — stick on something like s3, and have it basically scale infinitely. Happy to help if needed!
- Gigachad 2y agoWhile also getting billed infinitely
- mikeocool 2y agoYou could also put cloudflare in front of it and leverage their free plan until they don’t let you anymore (which is my experience for something like this is pretty much forever). Or you could host it with a plain old web server on a hosting platform that gives you fixed bandwidth for a fixed price. And it probably still scale well enough to survive a front page hug.
- scrame 2y agothis doesn't work on mobile for me. tried in chrome and Firefox, but I just get the splash page.
- kgeist 2y agoSame. Strangely, switching to Desktop site mode doesn't fix it.
- Bencarneiro 2y agoOK holy jeez I think I got the server back up. We now have 8X the ram and I'm not sure how, but we broke postgres....
- ppbjj 2y agogodspeed, soldier
- et-al 2y agoNot to sure how your backend is set up, but it looks like you're generating GeoJSON on the fly and the JSON serialization for this amount of data can be slow. In typical HN fashion, I would suggest looking into using Tippecanoe to generate some vector tiles of the data and host that on S3. Then the DB can fall back to performing simple lookups via the accident ID. Filtering by time will need to move to the frontend, but that should be fine (if not, look into clustering the data at further zoom levels). https://github.com/mapbox/tippecanoe https://github.com/mapbox/tippecanoe
- Bencarneiro 2y agoThis is very helpful
- wcedmisten 2y agoI've built quite a few open source mapping projects myself using Tippecanoe and other tools. Feel free to email me if you want help setting this up!
- woudsma 2y agoYou could also take a look at PostGIS to do geospatial queries (if needed). And in the past I’ve used node-mapnik to render vector/image map tiles. You can indeed host and cache them effectively on S3.
- et-al 2y agoHi Ben, briefly took another look this morning and I'm sorry for the hasty rec because I forgot Leaflet doesn't support vector tiles as easily as MapLibre/Mapbox. If the bottle-neck is the DB and you haven't enabled the PostGIS extension, I'd look into that as the other commenter mentioned. If it's your server, then yes look into pre-generating all the tiles and hosting them elsewhere, but this might then mean switching over to MapLibre/Mapbox (which is what most companies end up using because of Leaflet's limitations). For filtering on the frontend, I'd look into Expressions so you're not regenerating the GeoJSON collection every time (this causes a significant delay and flicker). - https://maplibre.org/maplibre-style-spec/expressions/ https://maplibre.org/maplibre-style-spec/expressions/ - https://maplibre.org/maplibre-gl-js/docs/examples/hover-styles/ https://maplibre.org/maplibre-gl-js/docs/examples/hover-styl...
- zoklet-enjoyer 2y agoMy friend, Josh, died the day before he should have started 9th grade. His brother got into partying and eventually hard drugs, I suspect at least partly because of Josh's death. He died of a heroin overdose in 2018. I've known several other people who've died on the roads around my hometown but I don't see them on the map. https://roadway.report/accidents/2003380044/ https://roadway.report/accidents/2003380044/
- y-curious 2y agoGreat job! I would love to see a writeup of how you did this!
- markstos 2y agoElsewhere, someone here linked to the national crash data set. Sounds like they used PostgreSQL/Postgis for the backend here to store the data. The web server grabbed it as GeoJSON and displayed with a mapping web framework like Leaflet. I did a crash analysis locally using the QGIS desktop software for some display and analysis, as well as Node.js and the Turf.js library when custom code was needed for spatial analsyis: https://mark.stosberg.com/the-most-dangerous-intersections-for-pedestrians-in-bloomington-indiana/?ref=hacker-news https://mark.stosberg.com/the-most-dangerous-intersections-f...
- irjustin 2y agoAs it stands, it's hard to draw meaningful insights other than "lots/few people died here". Things that makes this difficult: - Roads change overtime. Added stoplights, more lanes, added roundabouts. Dramatically change the rate. - Volume of traffic. Deaths per cars would be interesting.
- hrdwdmrbl 2y agoAlso, there's no indication when a pin is 1 or multiple deaths
- jdwithit 2y agoUS 287 between Fort Collins, CO and Laramie, WY is notoriously dangerous and your map certainly bears it out. Click on any random stretch and it is absolutely full of pins :( Crazy because it is a wide open rural highway for the most part where you can see for miles. But it's only one lane on either side which leads people to try to pass recklessly. Plus there are some sudden turns and changes in elevation. Connecting two college towns probably doesn't help, either. Thanks for sharing (and good luck keeping the site up). It's the definition of morbidly interesting.
- bonestamp2 2y agoVery cool. It would be awesome if you could lift some of the major contributors of the accident/death up to the top (wet conditions, driver was drinking, driving too fast, etc).
- jorgesborges 2y agoI'm not sure the intention here but in an addition to being an outstanding project it's also a hideous indictment of 21st century transportation. So much life lost as a result of apes clumsily manoeuvring heaps of metal across painted lines of asphalt.

- youssefabdelm 2y agoSomeone needs to Tufte-fy this. I don't know if it's the hug of death or not but when I zoom out, I don't see (what I assumed would be) a distribution of deaths, a sort of heatmap of occurences. Then if you add a time dimension with color or some other parameter, it could give us a sense of what areas are most dangerous to avoid. At the moment the pins / tooltips are not very ergonomic and they obscure more than they reveal.
- doublegreat 2y agoWould really be interested in aggregating some of these stats e.g. which vehicle is most common in these incidents.
- gwbas1c 2y agoDoes this work on Android at all? I just have a static image. Using Brave.
- owlbite 2y agoThe title on the image is also a link to the actual map. Took me a while to figure it out too.
- can16358p 2y agoSo, is the whole webpage just a static JPEG image of a car crash?
- ray_v 2y agoNeat! Nearest traffic fatality to my house happened 22 years ago. Oddly it involved three women -- two in their late 70s and one in her late 90s.
- xk3 2y agoThis is interesting in of itself but it might be more useful if it was weighted for population (ie. traffic without deaths)
- timzaman 2y agoNot sure what the data source is, but I crossed referenced with local news of pedestrian traffic deaths, and they aren't showing up on the map.
- nasseri 2y agoThank you for putting this together. I live in an area that has terrible traffic patterns for pedestrians and I always suspected it had a higher than usual fatality density. Now I know for sure!
- postscapes1 2y agoI have been looking for something like this. To clarify it doesn't show pedestrians or bikes hit by cars? ( I live near a stretch of road that I know has several white bike memorials but this does not see to not have them there..)
- Bencarneiro 2y agoData included is specifically 2001/01/01-2023-01-01 if that makes a difference.
- daemonologist 2y agoThere's a pedestrian fatality on the map near me. Might be a problem with data gathering/consolidation - apparently data collection is done by individual states (and of course they're themselves distributing it out to a huge number of different counties/municipalities/PDs).
- nullhole 2y agoI've worked with stats in this area before and it's not pleasant. You can't escape the reality behind the numbers, not that you should.
- colordrops 2y agothis is super fascinating. I'm sitting here with my kids going through accident after accident in our neighborhood and piecing together what happened for each one. Every report tells a detailed story. We can't stop.
- anothernewdude 2y agoFlatten your data down to a heatmap
- emsign 2y agoHorrible pic. That's all?
- system2 2y agoWhen I change the area it does not refresh. It would be nice to have a "search in this area" button just like google maps to refresh the viewport.
- danglingptr 2y agoVery interesting. I can imagine this map would benefit from a different kind of visualization. Maybe a heatmap would better accentuate problematic areas.
- lawgimenez 2y agoI don't get it, the pins are concentrated only in San Jose California. I am not in the US right now.
- cool-RR 2y agoBad UI. You need to double-click the desired area. Not sure what to do on mobile.
- lawgimenez 2y agoAh got it thanks!
- winrid 2y agoJust tap the map once on mobile to refresh it seems.

- sizzle 2y agoCongrats, I wish I had this data over the years to avoid roads. I saw Waze had a feature for intersections that had higher accident rates. Is there a way to use the data to get a percentage or score for how dangerous a freeway is between 2 points on a map or something? Suggest an alternate freeway or intersections?
- yalok 2y agois it just me, or 101 is 2-3x more dangerous than 280 per this map in Bay Area? definitely more density of pins on 101 (you have to click to the center in between these 2 highways to see pins on both). It makes sense, since 280 is a bit less loaded, and built better, has full shoulder in most places. The split to 85 going south on 101 is a very bad place - 7 pins very close together.
- jac241 2y agoStrong work. Looking forward to / dreading the update with the 2023 and 2024 data that I've been more involved with. RIP to all of the young people in their late teens and 20s who made the mistake of using a road for anything other than driving. RIP to the older folks who got smoked just crossing the street. RIP to everyone else who didn't deserve to go. Hopefully there is traffic calming and reliable, frequent public transit in heaven. Unfortunately this dataset doesn't include the, probably more frequent, severe TBIs. Surely wouldn't take many patients for the cost of a hemicraniectomy, 2 week neuro-ICU stay, trach/peg, and long term acute care stay to equal the cost of a few measures to slow drivers down. Not to mention lost earning/tax potential. Too bad it's not from the same budget. Wear your seatbelt and a helmet and hopefully you can avoid the pain of your family having to have a surprise end-of-life discussion with me.

- rmason 2y agoIt would be useful to be able to filter for season such as winter vs rest of the year and time of day. Quite sobering to look at clusters of deaths in your home area that you wouldn't have predicted. Love to know which roads to avoid in bad winter weather or when driving in the early AM hours.

- markstos 2y agoI've done traffic crash analysis at a city-scale: https://mark.stosberg.com/the-most-dangerous-intersections-for-pedestrians-in-bloomington-indiana/?ref=hacker-news https://mark.stosberg.com/the-most-dangerous-intersections-f... One thing that's striking at is that the fatality locations do nor correlate with the "highest crash rate" locations hardly at all. The intersection where you are most likely to get hit has a high pedestrian volume and often (in theory) low speed traffic. While the fatalities here are more likely to happen on high speed streets, sometimes in locations where no one expecting a pedestrian. Put another way: if we were try to fund "fixes" for the locations with fatalities, it would be mostly locations with a single fatality at those locations, while we have plenty of locations that have several pedestrian-involved crashes per yet.

- waldothedog 2y agoThanks for this, it’s a helpful visual that I deeply appreciate. It was weirder than I anticipated to see a best friend’s death reduced to an incident report. PS you may need to explicitly search to get results returned (I did)
- macrolime 2y agoI live in a similarly sized city to San Francisco in Northern Europe and San Francisco has almost two orders of magnitude more traffic deaths each year.
- macrolime 2y agoFor the downvoters, yes a slight exaggeration. The year I checked, 2019 was 1 vs around 30, so just slightly over an order of magnitude if you want.
- johnnybzane 2y agoThe number #1 cause of car crashes is the presence of cars. Walkable communities have less cars, therefore, less car crashes. The city grid is mainly to blame. The city grid of most American cities is uniquely bad - filled with streets which run at right angles to each other. Take a look at Brussels vs Queens New York. Brussels had 5 road deaths in one year. Queens New York averages 75/year. That's almost a 7x difference adjusted for population. Brussels has as an extremely irregular and walkable grid. Queens, like Manhattan, is full of dumb dangerous straight-lined roads and 90 degree angles. The more irregular the grid the lower the traffic fatalities (assuming you're in a high-income country). Why do suburbs have cul-de-sacs? They have curves, and They are useless as roads. They force cars to slow down, and disincentivize automobile traffic. Ergo, less cars, and your kids might get away with playing in the street without getting hit. Rip up the grid and build a walkable community. It won't be cheap. Upzone and lower property taxes for any private developer that builds affordable housing on a walkable grid in your city. There's only one place in the United States that's trying - Culdesac Tempe in Arizona. Northeast/California NIMBYs won't let you dare try to fight off their localism. They vote. Do you vote?
- nothercastle 2y agoCuldesac might work ok if you allow bike and pedestrian thoroughfare at the end point. Otherwise they are impossible to walk or bike due to long distances to get anywhere
- ajryan 2y agoSouth shore of Alamdea CA has this and it’s great. My kids called them the “secret paths.”
- systemtest 2y agoCar ownership in Brussels is 45% versus 62% in Queens, that is also a factor. Number of traffic deaths in Brussels in strangely fluctuating, one year it's 6, the other it's 20+. Might be a COVID thing. Still less than Queens.

- lukeasch21 2y agoI could be wrong on this one, but I vaguely remember Waze adding an alert like this recently.
- blincoln 2y agoMaybe I missed an alternative mode that's already present, but this feels like it would benefit enormously from a heatmap view, so that one could see where fatality hotspots are at a higher level before zooming in to examine specific locations.
- acchow 2y agoThis would just end up being a population density heat map, right?
