Roads
A real evacuation plan wouldn't look like Tuesday
Imagine we needed to evacuate downtown DC and Arlington quickly, in the middle of the day. What would be the best way to do that?
We know what wouldn't work: telling all employees to go home at the same time. That's pretty much what happened Tuesday after the earthquake. No bridges or roads were damaged, though some traffic signals had switched to flashing red or had lost time synchronization.
The Metro ran at 15 mph, causing huge crowds and long waits for those riding. But that couldn't have much affected the numbers of cars on the road, since anyone who didn't drive into work wasn't going to drive back home.
Can our transportation network possibly move so many people at once?
Roads are a very flexible form of transportation, but are inefficient in their use of space. Each car takes up a lot of room. The New York Subway's 22 tracks carry as many people as at least 167 lanes of car tunnels would.
If people drove evenly throughout the day, the road network would work optimally, but they don't. Buses and trains work better for moving people in a shorter time period to a small number of locations, because they cost more to run but can fit more people in a smaller space.
There are ways to make the road more efficient. More people could occupy each car. That's the logic behind the HOV rules and slugging on I-395 and other roads. Thanks to slugging and high bus volume, 95/395 is one of the most efficient roadways for its size in the nation (but will actually get less efficient with HOT lanes).
Instead of pushing more carpooling, VDOT actually waived the HOV restrictions on its freeways on Tuesday. That doesn't make a lot of sense. It's like they just threw their hands up and said, "Wow, earthquake! Let's just ignore everything we do to make our roads work better!"
If we knew ahead of time that we'd have to evacuate DC in a hurry one day, but didn't know when, we might actually plan for stricter HOV restrictions than usual. Take a few main arteries and make them exclusively HOV-3 or HOV-4 for the evacuation. Ask workers and residents to find "evacuation buddies" who work in the same office or live in the same inner neighborhood. These people would share the car when evacuation time came.
Once those carpools get to suburban residential areas, people will have to get home, but depending on the type of disaster, just getting everyone out might be most critical. The drivers can give rides that one time to their passengers, or they can wait in places like libraries for family members to pick them up.
Buses could also use the HOV roads, allowing them to travel much faster back to commuter lots and make a return trip to pick up even more people.
Not surprisingly, advocates for more roads and sprawl, like the Northern Virginia Transportation Alliance, immediately jumped on the issue to call for new Potomac River bridges as part of their long attempts to build an Outer Beltway. Such bridges wouldn't actually alleviate existing traffic congestion, but would instead just drive more sprawl development and make the evacuation challenge that much harder.
During the earthquake, Ezra Klein cleverly tweeted, "This earthquake has clear policy implications that back up my previously held political opinions." That's certainly true for NVTA.
I actually learned something from the earthquake that doesn't back up previously-held opinions: we can't count on Metrorail for an emergency. Especially with today's safety concerns, Metro is going to err on the side of limiting its operations in unusual circumstances. That's probably the right move if it's not a matter of life and death. But it means we need to think about evacuations another way.
We also need to think about when evacuations are necessary. Often they're not. One of the best things the federal government can do is not to send everyone home at the exact same time. Instead, the response from OPM seems to be to pull the "everyone go home" handle at any sign of trouble. We know that this causes gridlock.
DDOT Director Terry Bellamy said at a press briefing, "You can never build your way out of an event. I know there was a lot of talk about building more bridges across to Virginia, buidling more bridges into Maryland, but you never know where the event is going to occur," the WBJ reported.
Transportation Planning Board coordinator Ron Kirby told the Post, "Not only can [sending everyone home at once] not be done, we should not try it. ... If you give [people] very good timely information, they are going to make their own decisions in ways, in general, that are going to be better for them and better for the system as a whole."
Kirby also faults Metro for not communicating more; he might not have been on Twitter, because they actually did an excellent job of communicating there. They also sent multiple press releases out over their press list throughout the afternoon and evening. If you were at a train station or on a bus, was communication good or bad there?
The best way of all to get home after a major event like an earthquake? Walk or bike, if you can.

The problem here is OPM and that they "control" some many employees. Releasing that flood is going to cause problems.
Dave clearly was not around on 9/11 or he would have know metro was not an option either.
The real answer: don't evacuate Washington. Don't panic.

The problem is that anybody living outside can not walk there. I'm in pretty good shape, but I can not walk 20 miles home.
You would also need an arrangement for "left" cars.
The fact that we can not count on metro is a major issue. I understand they went slow for a bit worried about damage. But as soon as the entire tracks had been covered by a few trains, the lack of damage should have prompted metro to resume normal service.

Since 9/11 I have always kept comfortable shoes, a toothbrush, and a stash of non-perishable food wherever I work. The problem is the overeaction and panic and how to moderate that. Even if I could have gotten home, if something was broken or flooding or burning, theres not much chance I could have intervened quickly enough anyway. I have good relations with neighbors who are home all day, and they have a key, and I asked them to just check for any water or gas issues. I realize ppl w/kids are a different story. But long story short is ppl need to chill, have a strategy, realize that staying put is usually safer. Frankly, DC-region denizens are control freaks and the panic over even minor events is a cultural thing that probably won't change.

People can walk 20 miles. It may take them two days, however. I have to wonder what the obese and handicapped are supposed to do. Darwin at work, I guess.
A great argument for bikes. Anybody should be able to bike 20 miles in a day. Perhaps DC should have thousands of emergency bikes stored in basements along with the crackers.

If I commuted by car to DC and there was a widescale evacuation, I assure you that the $500-1000 fine for using HOV (if the restrictions weren't lifted) wouldn't be worth it to me. In the case of something extremely major, I highly doubt many people would have to think between "violate HOV" and "die".
If the restrictions aren't lifted in an emergency, what happens when 395-S is completely stopped and the HOV lanes have a few cars in it? Are those passing by on the HOV going to say "Well, that's what you get for not carpooling! Enjoy the radiation poisoning."?
There's no reason not to lift the HOV restriction in the event of an actual emergency evacuation.

Which brings me to another point. Metros problem wasn't that they were going slowly. It was that they never increased the volume of trains until the standard rush hour time.
We've seen in situations in the past (Obama inuaguration) that Metro can accomodate far more volume if there is a plan for it. Metro doesn't have a plan for situations like this.
The earthquake happened just before 2. People were streaming home by 2:30. Metro didn't increase the number of trains until the typical rush hour time, by which the system had already been choked with people for hours, enduring 12-15 headways to get on trains going 15 mph.
You would think that Metro would have a system in place where they could surge the system with additional trains within say...1 hour after an emergency strikes. I know its not fiscally sound to keep twice as many conductors in a room waiting to jump in a train in case of an emergency, but this isn't that hard. Have a revolving "on-call" system. Pay the train drivers who live closest to their respective rail yards a little more to be "on call".
The local DOT's already have the road situation figured out, which ones become one way evac routes, which ones lose HOV ROW (which is smart by the way, it increases the total volume of people able to leave a given area). Metro needs to figure out how to surge their system in less than 8 hours.

Also, many people I know who drive to work when other transportation options make more sense are wedded to their cars in ways that supersede logical considerations. I DEFINITELY can't imagine them not just hopping in their cars and going (or rather, sitting in traffic), no matter what anyone else is saying to do or what makes sense. Just to clarify, I'm not talking about most car owners, just a few people I know who insist on driving everywhere even though it's more expensive, slower, less convenient, etc. Most people I know who own cars know better than to commute in them.

"During a major event or emergency situation, radial evacuation routes featuring traffic signals will be timed. In addition, 70 critical intersections on the event/evacuation routes within Washington, DC will be manned with uniformed police officers to expedite the flow of traffic and to prevent bottlenecks. Also, these officers will direct you to alternate routes should an emergency warrant the closing of current event/evacuation routes."
Which is pretty much what happened right? Oh, it didn't?

With regard to Metro, that's not the actual problem. Metro did work to increase train headways as soon as possible, but even when all rush hour trains were operating, service was still reduced.
Why? Because if it takes longer for a train to run its route, you need more trains to keep the same headway.
Let's look at an example:
Let's say I have a subway line 10 miles long. The average speed on this line is 35 miles per hour (including station stops). It would therefore take one train 17 minutes to go from one end of line (station A) to the other (station Z).
If we only have one train, we could have a headway of 40 minutes. The train could leave station A at 12:00 and arrive at station Z at 12:17. It would wait 3 minutes and then depart at 12:20 for station A, arriving at 12:37. After 3 minutes, it would depart at 12:40. That's 40 minutes between trains bound for station Z departing from station A.
If we have 2 trains, we could have a headway of 20 minutes. With 4 trains, a headway of 10.
Now, let's change the equation. Let's make the average speed 10mph (with stops). It now takes 60 minutes for 1 train to go from A to Z.
With a recovery time of 3 minutes at each end, the headway could be no greater than 126 minutes (1 train every 2 hours 6 minutes).
With 2 trains, the headway would be 63 minutes, and with 4 trains, 31.5 minutes.
In order to get to the "normal" 10 minute headway, we would need about 14 trains, or almost 4 times as many as if the speed was 35mph.
Now, Metro can call up some extra personnel, but not that many.

The fact that Tuesday was a traffic disaster doesn't surprise me. The transportation is already at capacity for moving the inhabitants of the metro DC area over roughly a 4 hour period. Throw any other variables in there like 15 mph run times and ignoring HOV rules, and the system breaks. Bikers and pedestrians are immune to these issues.

But what SHOULD be done is to get people to plan, in advance, on how to evacuate the workplace. This does NOT include a half-ass fire drill where everyone just stands around the stairway entrance and chit-chats, but a *real* fire drill where you practice hurrying down the stairs and out the door to a pre-designated meeting spot.
And, what this post brings up is people ALSO need to plan, not just for evacuating the building, but evacuating downtown. This includes thinking through access to water/food/facilities, figuring out mode of transportation to get home, AND finding a "carpool buddy". The federal government can have a role in encouraging people to prearrange, in advance, who they will get an emergency ride home with if need be.
I have a little bit of experience with this. On 9/11, I was working in a Center City Philly skyscraper. Our building was completely evacuated. The president of our company made the decision that no one should ride SEPTA home because we didn't know whether the trains would be running or not [they were]. So we all quickly scrambled to get rides home. Because there was no pre-arrangements, this caused quite a bit of confusion.

Since it wasn't really an emergency, Metro's play-it-safe approach is completely justified. But Metro does often seem to see itself as an optional part of our infrastructure, and not the core, bedrock mobility that it is. The idea that 200K+ downtown workers should prepare their own "alternate way home" is shirking their responsibility, which should be for Metro to find an alternate way to keep their riders moving.
For the few instances of an emergency where downtown will be less safe than people's homes, I hope Metro does have some sort of contingency plan. Since the trains are nearly automatically run anyways, are there provisions to let some trains run driverless? Or to have other Metro employees as emergency train drivers?

There's some DC "emergency" agency or other that I still receive emails from even though I have asked repeatedly for them to stop. About 4 or 5 years ago, they held a training for what to do in an emergency. I'm not sure if they're still around (the same woman who led the training keeps sending me these annoying emails - maybe it's the Health Emergency Preparedness and Response Administration) but they are utterly useless. The take away I got from that training was how to prepare an evacuation bag and don't have candles in the house. Otherwise, they were VERY hands-off (almost a situation of "let's avoid all liability at any cost") and would not talk about specifics of how to evacuate a building, let alone a city.
Of course, we have the DC Homeland Protection agency.
And these blogs, proposing changes in such a way that they will never happen.

Keeping that in mind, it's no wonder that there was panic. I mean it's hard to explain and not panic when you feel the ground move beneath you or see windows rattle and not have a "WTF" moment. I unfortunately didn't leave work until 5 but got from FNorth to Anacostia in about 30min, which was only minutes outside of the norm. I understood that some people on the orange/blue lines (specifically those @L'enfant) had a really long wait but I didn't have much to really complain about.
I don't think that DC lacked an evacuation plan or that the plan didn't work. The problem were the people..not the plan. Post 9-11 It's no way in the world that people will choose to remain in their offices and wait to hear from their employers. Emergencies bring with it chaos. It just did.
Ironically, New Orleans was blasted for it's lack of emergency preparedness. Well imagine if the potomac and Anacostia rivers had flooded. Not sure how much an emergency plan would've helped.

I think it's impractical and certainly poor politics to use police officers to enforce HOV restrictions during an emergency or a panic.
Where I was during the earthquake, there was no general panic like everyone seems to be talking about on this thread. Most people, including myself, headed home because the building was evacuated and we didn't know how long it would be before we could get back inside. Also, while there was no general panic, many people felt too rattled to just go back to work like nothing happened, so they went home. I have a feeling that the brave souls who just "went back to work" were more likely spending their time on facebook, blogs, and email trading earthquake stories.

Around 3:45 or so, OPM posted a message under it's "operating status" and I don't recall it ever instructing everyone to go home. From what I remember reading, it said something like "Some agencies have begun to allow their their employees to leave early. Therefore, we are recommending early dismissal for all federal employees"
Now while my phrasing isn't exact, I know for a fact that the "some agencies have begun..." point preceded the actual dimissal from OPM. I understand that you're basing your opinion on the extent of "panic" off of DAl's belief that they told everyone to go home at the same time. But it's not really an accurate reflection of what occured. I even remember the same yellow "caution" icon that's up on the site now.
All this to say, your assertion that the "professionals" panicked isn't supported by any real facts. After reflection, I think even DAl would agree that his take on it wasn't exactly based on an objective fact. They didn't send everyone home at the same time. They just didn't. They left a bit of wiggle room and didn't simply close down the fed gov't.

It's not fair to compare Tuesday to the inauguration or any other planned event. While there may be trains available sitting in rail yards, you also need people to operate them. Yes, you can keep people on call but you still need to obey federal regulations pertaining to how much rest people need between shifts.

No one should have left home early yesterday, including schools; however, in an acutal evacutaion, students should be evacuated togther to predetermined locations, where they will be safe until a parent or guardian is found and cane pick them up in person.
Instead, the schools just gave up for the day and sent the kids home alone. It's no wonder everyone in DC felt the sudden need to leave at the same time.
If they thought their kid was safe, maybe they would have been more comfortable waiting for an orderly evacuation. (and why did we evacuate DC again?!)

The criticism of the HOV lanes being opened is simply not serious. Opening it allowed more traffic to move. Expecting people to make HOV buddy brigades while they're trying to get to their kids' schools or daycares is equally not serious. Not everyone is fortunate to live so close to where they work that walking or cycling is an option.
Unlike 9/11, I saw no panic on Tuesday. I saw lots of confusion and frustration, but no post-quake panic. Those that were here on 9/11 remember what actual panic and fear looked like. Tuesday was hardly comparable in that sense. But it was comparable in terms of total traffic gridlock for several hours and the clear inability of the Feds, city, and surrounding counties to have a comprehensive evacuation plan that can be activated until at least a few hours after an emergency has occurred.
by Fritz on Aug 25, 2011 11:18 pm • link • report
If anything, the needs of evacuation are another reason to strongly discourage automobile commuting in the first place. Trying to impose an HOV restriction is understandable but it would never work. (Though, I suppose MPD could develop an "emergency bus lane" plan, maybe?)
Where I work, the evacuation alarm went off about 45 seconds after the shaking stopped. We were sent home about 3 because it was obvious by then that the AOC wouldn't let anyone back into our buildings before they were inspected, and that wasn't finished until 9pm when staff and visitors were allowed to collect their belongings. The only part of the evacuation that mostly worked was the unwritten part, that is, "when you leave, be ready to go straight home, grab all your stuff first." A couple people I know did get stuck till nine, which had to be awful.

2) Mayor Vincent C. Gray Urges Residents to Prepare for Potential Impact of Hurricane Irene
The District is ready to respond to hurricane; agencies are gearing up to meet the challenge
(Washington, DC) Mayor Vincent C. Gray is urging residents to take the necessary precautions to meet the challenges that may be presented by Hurricane Irene. The hurricane is a Category 3 and the National Hurricane Center has placed the Washington, DC metropolitan area on hurricane watch. Hurricane Irene can bring heavy rain, flash floods and high winds to the area. The city is getting ready for the impending storm and placing agencies on alert.
"While we cannot predict with certainty the path of the hurricane, residents must be ready," said Mayor Gray. "That means residents need to have a plan that they can activate. If they do not have a plan, they can go to hsema.dc.gov to learn what is needed. These storms can cause power outages that may last through several days. Residents should have an adequate supply of medications, infant formula, water, fresh batteries and other essentials."
Gray's emergency management team met today and is ready to deploy resources as needed. This week the team participated in an exercise to hone their skills in response to a hurricane.
The Department of Public Works will assist residents with preparing their homes to withstand flooding by distributing five sandbags per household beginning at noon, Friday, August 26, at its New Jersey Avenue and K Street, SE site. The entrance is at New Jersey Avenue and I Street, SE and staff will be on hand to direct residents to the distribution point. Distribution will continue through midnight Friday, then resume at 8 am, Saturday, August 27, through midnight Saturday. Residents will be asked to show a DC identification.
The government is constantly monitoring the weather and will update the public as more information about the storm's track is known.

OK, you wouldn't feel comfortable going back into your office until it was inspected after the earthquake. What about your house/ apartment building? Is there any reason to think that any building one evacuated to after the earthquake was inherently safer than the buildings from which one evacuated?
by thm on Aug 26, 2011 10:33 am • link • report
Fair point, but my question is why does emergency planning assume I will stay with my damaged office building? If it is damaged why would I even try to shelter in place there? Even awaiting inspection can take a long time - I read in comments above that buildings on the Hill were re-opened by the AOC at 9pm; my building was not cleared officaly until late Wednesday. No one is going to shelter at locations under those circumstances; if anything, they are going to head home to see what the circumstances are there, and then figure out what comes next. So unless the city is actually being evacuated - emptied out by order - people will head home. This is what happened on Tuesday, we didn'thave an evacuation, we had an early rush hour. This will continue to happen in future (non-evacuation)emergencies - rush hour will happen shortly after whatever incident settles down. Therefore, we should not be surprised by this; emergency planning needs to acknowledge this possibility, and not assume folks will hang out in some non-home, non-office limbo.

But overall planning is also necessary. In a situation like the earthquake where the city doesn't NEED to be evacuated, staggered releases seem reasonable. However, you're right about making it too easy to flee. As soon as we got out of our building (less than 1 minute after the shaking stopped), 14th St. NW was a mess with people who just decided to leave, release or no release. Those people should not benefit from relaxed HOV regulations. Buildings were not toppling down in DC, there were no immediate threats to people doing as we did...wait out the initial inspection of the building, go in and gather our stuff, go have some drinks, and then board the Metro after the crush passed. Sure, I was passing out sunscreen to coworkers unprepared to stand outside for an hour (I grabbed my purse which always contains sunscreen before we hightailed it out of the building, knowing that we might not be let back in, and even if we were, I was going to be standing outside for a while and needed UV block), but a very slightly increased risk of melanoma was the most serious concern.
In a serious evacuation emergency, all roads should be turned outbound only, busses (only) should be allowed to use shoulders and every one available should be mobilized, HOV regulations should be enhanced, trains should be employed in an outbound-intense manner, and neighboring city's bus systems should be mobilized to move people further from the epicenter. I have little faith that my basic laywoman's take on this will be employed, but it's imperative that we think about this.
