2011/03/27 Plea To Caltrans: Improve Your Communication

π 2011-03-27 01:01 in Nsnow, Public, Snow

Dear Caltrans,

This post is about your work around Tahoe, and what you can do to improve. First, I need to state that Caltrans folks who clear the roads day and night in sometimes horrid conditions, have a very hard job. In my experience with Tahoe, they actually do a good job with keeping roads open in bad conditions with the resources they have.

Yet, they could definitely do better. By that, I don't mean work harder, I'm pretty sure they already work hard during the big snow storms (especially the ones we had this year), I mean by improving communication.

In a nutshell, as much as you do a good job with roads, you do quite poorly with communication. This is partly why I wrote my "Tahoe Road Info for SR88 (kirkwood), US50 (South Lake Tahoe), and I80 (North Lake Tahoe) or making caltrans road reports more liveable" page. But my page is just making the online caltrans info a bit more useful, it does not fix underlying problems with how you communicate (or don't communicate in many cases).

Why the goals below are worth following

1. By increasing the frequency and standardizing the format of online updates, Caltrans could improve road safety by redirecting travelers towards the safest roads where Caltrans has the largest crew working.

2. A good example of providing realtime updates to a time sensitive real world situation is: http://www.google.com/crisisresponse/japanquake2011.html#map. This includes visualization and real-time social updates (if you had a twitter hash tag, then some drivers would probably update this info in real time for you!).

3. Your audience increasingly uses the desktop internet and mobile devices to get information, and this peaks during winter driving times (700x growth from baseline!).

4. Improve communication and increase driver safety, as per your mission statement on http://www.dot.ca.gov/hq/paffairs/about/mission.htm

5. Not that your main goal should be to have a better web site that other states like Utah, or Nevada, but being far behind them is obviously a sign that things should be better. See for example:

http://511.commuterlink.utah.gov/tats.web.report

http://www.safetravelusa.com/nv/?map=Sacramento

6. Put an end to road user frustration and anger that were avoidable.

You don't want drivers to drive 2-3H around Carson Spur because they didn't know you'd actually open Carson Spur at 07:30 after having worked on it during the night.

You don't want for one of your employees to plain forget to change the road status for 88 to show that Carson Pass had re-opened at 05:00 that morning (road change status was delayed by 3.5 hours and too late for those going to kirkwood that day, causing monetary loss to kirkwood and frustration for users who had spent hours driving to South Lake just to go to Kirkwood).

You also don't want not to tell road users you're planning to open 80 in about 1h after having closed it for 8H, causing some to drive towards 50 (a long drive around), just to close 50 at Myers for 5 hours without even making any mention of this on your road status updates (another of your employees plain forgot to update the status that day it seems): one of my friends got home 6+ hours later than necessary, exhausted, just because you didn't provide him with useful and timely information (and of course, such a driver is much more likely to get into an accident as a result, and cause one of those roads to be closed further)

So, how do you get there?

Target Goals

Let me summarize my suggestions here:
1. Report tentative/planned status changes.
2. Report actual road status changes as quickly as possible.
3. Maintain a history of status changes, in addition to current status report.
4. Standard format for status reports (i.e. computer parsable) and a graphical map with summary view.
5. A blog like page where you tell us about the challenges you're facing with your job, like why you can't plow a road because of conditions or because your equipment is tied up elsewhere (that's just for extra points)

So, let's start with my #1 suggestion:

Caltrans: you should announce tentative road changes, and report road changes as quickly as practical, and reliably

To give you credit, I've seen two instances where you did over this ski season:

Once, I've seen you display on a sign on 88 'Carson Spur will close at 7:30' but that was not available online. In the end, due to bad snow, you actually closed at 7:00 and we didn't make it. Mind you, I'm not mad, I actually want you to give out forecast info even if it turns out not to be fully right (in that case, some cars did get avalanched on and had to be dug out of the snow, not exactly Caltrans' fault).

Now, I also have to state that that same day, when we drove around to Carson Pass and their sign at 50 and 89 said 'Carson Pass closed, no ETA' when you were working on it and it opened 30mn later.

Actually another time, I remember that you posted 'Spur will close at 13:00 for avalance control'. Ok, you did actually close it at least 15mn early so we didn't get out of kirkwood as a result, but eh, at least you tried.

Now, let's look at a sample of the many instances of what you've done badly with communication:

In my Carson Pass example above, we lost $300 for a condo at kirkwood we were not able to get to (we turned back and stayed in South Lake) when Caltrans was actually working on opening the Pass and the sign gave strong impressions that your guys had gone home for the night (it was midnight and snowing hard, so it wasn't an unreasonable conclusion).

In just one 10 day period, I noted 5 different examples where the Caltrans web site failed to note some road changes, or did it very late, 4 of them were just in 3 consecutive days (!).

Sunday March 20: hwy 50 was closed about 5H at Myers for avalanche control and maybe accidents, I have a friend who was stuck there and waited the entire time. It was NEVER announced on the caltrans web site.

Thursday March 24th: 50 closed at Twin Bridges around 23:00 due to an accident and was closed for almost 2H. It took 50mn for the Caltrans website to show that traffic was being held (not as bad, but still, 50mn is pretty slow).

Friday, March 25th: Carson pass on 88 apparently opened around 05:00 but was marked closed on the Caltrans web site until 08:30 (!). This really screwed kirkwood over because people went to Heavenly thinking the road was closed, when it actually had opened a long time ago. Caltrans eventually fixed the road status after phone calls from Kirkwood trying to get you to fix it. That's pretty sad.

Saturday, March 26th: Caltrans did a great job and opened Carson Spur at 07:30, but there was no way to know you were working on it. All the people going to Kirkwood that morning were not likely to just drive to the Spur on the off chance that it might magicallly open without having Caltrans at least give a hint you were working on it (the Spur has been closed for 3 consecutive days 2 or 3 times this season, so we're unlikely to just drive to it when it's closed now).

Saturday, March 26th, still, Carson Pass actually closed around 08:30 due to 2 Subarus spinning out (I was there). It was closed for almost 90mn, and there again there never was any notice on your status web page. Quite unfortunate to say the least.

Caltrans, you work hard on keeping roads open, or re-opening them, but I beg you: you *really* need to communicate what you're doing.
Of course, you can't be everywhere all the time, use us, drivers, on roads that have cell service at least (won't help with hwy88, but at least it will for others), and use us to report up to date problems, accidents and road closures online quicker than you can when applicable.

Caltrans blog for each road

Here's my suggestion to you Caltrans: for each road you should have a blog-like page announcing what your plans are for a given road. You obviously have guys who figure out whether they're going to try and re-open Carson Spur on 88, or how long you think you'll keep it open. You also know if 50 and 80 are in such a bad shape that you had to send all your equipment there and therefore you won't be able to work on 88 anytime soon. So:
Blog it
I'm not trying to get you to go social because it's cool. I don't care much for facebook or twitter, but please find a way, any way, to let us know what your intentions are. I'm not asking that you tell us that you'll reopen the Spur at 08:22 tomorrow morning, I'm just asking for:

tell us if the road or conditions are so bad that it's unsafe for you to work.

tell us that your equipment for 88 had to be diverted towards 50 and you won't be able to reopen 88 anytime soon if that is the case (I'm assuming that's the only valid reason for 88 to be closed for 3 days in a row during a bad storm. If that's not the case, save us from assumptions, and tell us the actual reasons).

do your best to tell us that you're planning on closing 50 or 88 at a certain time for pre-emptive avalanche control when you have such a plan, or for 88/Spur, just to tell us when you think you'll be closing it for the night, or even over a day during bad storms.

tell us each time if a road is closed for snow or an accident (sometimes you do, thanks). If you have any tentative ETA, give it (you konw whether you're waiting for a snowplow or a tow truck and whether they're 30mn away or 2h away). We're not going to hate you if you get the ETA wrong, but you'll help us big time if you say "we're plowing and hope to reopen within 2H", or "two cars have to be dugged out, all tow trucks are already busy, it will take a while". Just give us all information at your fingertips and your best guess. A wrong guess is better than no info at all.

for heaven's sakes, if you got your crews up at 04:00 to reopen Carson Pass, or you have crews working through the night trying to reopen Carson Spur for the saturday morning crowd, then tell us you're doing that so that people can decide to chance a drive to the Spur and wait it out if it's not quite open yet. You close the Spur for 3 days at a time sometimes, so you can't expect that we'll just get up at 04:00 and drive up there on the off chance that you might open it if you don't tell us that you're actually planning on doing so.

Similarly if you opened Carson Pass at 05:00, don't have one person in an office not doing their job ruin it for all of us by not posting until 3h30 later (unless it's a problem where it never even got radioded to your office after it was done). Example from this case:
IS REOPENED FROM KIRKWOOD (AMADOR CO) TO 5 MI WEST OF PICKETTS JCT (ALPINE CO) AT 0828 HRS ON 3/25/11

Also, the reason why I mentioned a blog-like page, is because it's worthwhile for us to know what you've done in the last days or the last week. It's even useful when you close a road to know how long ago you closed it: for instance when you closed 50 for avalanche control as I was driving up, it was useful for me to know (through my own page, not yours), that you had closed it 1H ago and guess that it'd probably reopen 2H after it was closed, which it did.

I did that part for you by scraping your web page and keeping history for me and others, but you really should do this yourselves. See: http://marc.merlins.org/snow/roadinfo/sr88

More user friendly as well as computer parsable status reports

Another reason why I created this page http://marc.merlins.org/snow/tahoe_caltrans.shtml is because how are we supposed to know where "Peddler Hill" or "Nayak" (really Nyak) are? Telling us a road status between points that most road users don't actually know, isn't useful.
Would it be so hard to give us a graphical map like what Nevada DOT tries to do by parsing your free form text data: http://www.safetravelusa.com/nv/?map=Sacramento ?
I personally have 4 months worth of data from you, and you can tell it's free form text entered by a human. There are some patterns but really it seems to depend on the operator and it's nothing that's easy to parse for computer for any kind of automation. As result, Nevada DOT has even showed incorrect road status for California on the graphical map because they couldn't parse your data properly.

What should you do? Well, I recommend that part of your reports be made out of drop downs so that the format is guaranteed to be the same at all times, and then the operator can add free form text that is useful to humans at the end without compromoizing the computer parsable section at the beginning. As an example to others, those are examples I've seen:

IS CLOSED 1.5 MI WEST OF KYBURZ
IS CLOSED FROM TWIN BRIDGES TO MEYERS
IS CLOSED TO WESTBOUND TRAFFIC AT 4.8 MI WEST OF STRAWBERRY
IS CLOSED FROM ECHO SUMMIT TO MEYERS
IS CLOSED TO EASTBOUND TRAFFIC FROM COLFAX (PLACER) TO THE NEVADA STATE LINE

So, we have 'AT X', 'From X to Y', 'TO traffic AT X', and even 'TO traffic FROM X TO Y', and probably a few more. Then a road can be CLOSED or have 'TRAFFIC HELD', which quite frankly are the same in real life, but you seem to use one or the other depending on the road for some reason.
Also sometimes you send a 'CLOSED AT 21:22' and then replace it with 'CLOSED' 5mn later. Sometimes you never send the 'AT XX:YY', so computer algorithms can't do much with data that is randomly missing.

My point is that all this could be simplified and be made more consistent. Please do what you can there.

Conclusion

Thanks for doing a lot to keep our roads open as much as possible during bad weather. Your Tahoe staff does do pretty incredible work. But please: let us know what you're doing, and maybe even give us some insight about how you're working on the roads and what you're dealing with.

This was a busy year, especially for March

Thanks,
Marc

2011/03/25 Another Big Storm Headed for Tahoe

π 2011-03-25 01:01 in Nsnow, Snow

Jennifer and I had just come back from Montana when the previous big storm hit Tahoe (we're talking 50-60 inches of snow over 3 days), so we ended up sitting that one out to recover.

However, when another similarly sized storm arrived the following week, it was hard to miss, especially as such big storms don't happen even once on some years.

We went with Martin and Matt in their chalet in South Lake. The drive on 50 on thursday evening was a bit gruesome because we left just a little bit too late and were delayed by an accident that happened 10mn ahead of us. In the end, we only got there past 01:00 instead of just after 23:00 :-

they need to clean that van :)

Martin's Subaru

Mmmh, the plow guy came that afternoon, but by the evening the driveway was unsuable already.

What can I say, it was a pretty good day, even with just one top lift open :)
This was a really sweet 'just my tracks' run in palisades:

and here is a mashup of other bits from the day:

The next morning, Caltrans had opened Carson Pass at 05:00 but failed to update their record, so it was marked closed until 08:30 :( That's a major fail from Caltrans and almost caused us to go to Heavenly (which sucked that day since everything was closed there).

In the end, we got to Kirkwood a bit past 10:00 and ended up riding Cornice all day, which was more than enough for that day :)

A quick summary of day 2:

The next morning, we went for Kirkwood earlier, but a couple of cars spun out on Carson Pass, closing it for another 90mn. Had we left 10mn earlier, we'd have made it... We were on the slopes around 10:30, which was just around the time that the Wall opened, so I was able to get a couple of rides off it, and they were pretty stellar :)

waiting in line again...

yes, it was snowing still...

a little bit of ice hanging :)

kirkwood staff was shoveling the snow at the top of the wall so that we didn't get stuck

Saturday was a really good day, except for the fact that wind closed the wall, so I only got to ride on it twice. This enticed me to stay sunday to actually ride the mountain that was still closed.

Jennifer went home saturday night because she had commitments on sunday (also she unfortunately hurt her knee by falling off the lift downloading on ice at the top of cornice). I spent the night with Jim and Matt who nicely hosted me at their condo in kirkwood.
Sunday morning, Arturo and Bill who had been stuck at Heavenly the previous day, were able to make it to kirkwood, so we met up.

a couple of skiers climbed on the roof and jumped out. Sweet!

5ft+ of snow wasn't for play, they really had it.

when the wall finally opened, there was a little bit of a line :)

come on Arturo, don't be scared, it's just a cornice ;)

the ride home on sunday turned out to be uneventful

A quick summary of day 3 with Arturo and Bill:

Thanks to Martin, Matt, Matt, and Jim for driving/hosting us.

2011/03/13 Big Sky and Moonlight Basin, Montana

π 2011-03-13 01:01 in Nsnow, Snow

Jennifer's sister and brother in law nicely gave us an open invitation to stay at their cabin by Big Sky, and we finally took them up on it.

United had the sole direct flight from SFO that left at some stupid ass time in the morning, ruining a night of sleep and a whole day for nothing (likely the only takeoff/landing timeslot they could get for a small pond jumper). We did however elect to take that since connecting flights take an extra 4H if you want to make a safe connection where your snowboard is likely to arrive too.

After loading up on groceries, the drive to big sky was a scenic 1H to the very nice cabin. After resting for the rest of the day, we went to Big Sky the next morning.
When we got there, they were all proud of the 8 inches they had just gotten of the last 2 days and their 105" base. I obviously didn't complain about snow, but I couldn't help but smile at how this doesn't qualify as a dump or a powder day in Tahoe :) At the time I write this, kirkwood in Tahoe got over 120" of snow in the last 10 days with 2 storms that delivered over 50" in just 2 days each.

Case in point, the kirkwood page had 145-160 inches of snow for the current storm :)

Kirkwood Snow Stats for 2011/03/27:

Last 48 Hours	64-70"
Storm Total	145-159"
Last 7 Days	164-183"

Seasonal Total Range	691-713"
Base Depth	229- 273"

Anyway, back to big sky, outside of the stupid early time we had to get up at, we had a good flight. The airport view after landing ain't bad :) and the drive to Big Sky from Boseman was scenic:

nice condos

it was nice and spacious

The next morning, we went to Big Sky, it was nice and sunny with a few inches of freshies left over:

line to the tram was ridiculous (1h)

did I mention that snow coverage was poor? :)

to make extra money, they also had ziplining

The next day, we went to check out the neighboring resort: Moonlight Basin (both resorts share a common area and you cna purchase a bundled ticket to ski from one side to the other). They were a bit more basic and cheaper, but they still had some interesting terrain, although the amounts of it were more limited :)

I found this hut by chance in a middle of a tree run

their best lift was actually uphill from the closest lift, so you had to hike there

the terrain from headwall was much more fun

their trees tended to be more dense than the Tahoe ones.

The 3rd day, we actually got some fresh snow. It was unfortunately too warm, so the bottom of Big Sky was very wet and the snow felt like ice, but when the top opened and we got there, it was better (not great, but much better) and made for some good riding until the end of the day:

And after a good 3rd day, it was time to go home after another nice scenic drive back to the airport:

lower octane gas at altitude for non turbo cars

All it all, it was good fun to check out the 'biggest skiing domain in America', too bad that the coverage was so low (my brand new board got scratched up).
A big thanks to Eva and Gordon for letting us use their nice cabin.

2011/03/03 Work Tahoe Ski Trip

π 2011-03-03 01:01 in Nsnow, Snow

We had a ski trip in my group from work, and went to South Lake Tahoe just before a small snow storm, which gave for some nice snow for our two days at Heavenly.

City of Myers

South Lake Tahoe

Deserts from the Party

The next morning, we took the gondola to go the top (thankfully Sky was opened), and we had a nice couple of bluebird days:

Heavenly does have nice views

Pow!

All for me! :)

View of Nevada on the other side

I love those views

Heavenly did improve their signage, especially for snowboarders:

Warning, snow can be cold. Oh, and you can die :)

Thanks Heavenly for warning snowboarders about the long traverse at the bottom

Killabrew has a nice view on Nevada though

But did I mention that Heavenly always had snow problems? This was off Cascades, WTF?

But eh, despite my harping on Heavenly, I had some really good tree skiing between Sky and the top of Tamarack (if you knew how to get around the rocks).
