MS Clearflow To Help Drivers Avoid Traffic Jams

kdawson posted about 6 years ago | from the get-me-outa-this dept.

Microsoft 243

Pioneer Woman writes "Microsoft announced plans to introduce a Web-based service for driving directions that incorporates complex software models to help users avoid traffic jams. The system is intended to reflect the complex traffic interactions that occur as traffic backs up on freeways and spills over onto city streets and will be freely available as part of the company's Live.com site for 72 cities in the US. Microsoft researchers designed algorithms that modeled traffic behavior by collecting trip data from Microsoft employees who volunteered to carry GPS units in their cars. In the end they were able to build a model for predicting traffic based on four years of data, effectively creating individual 'personalities' for over 800,000 road segments in the Seattle region. In all the system tracks about 60 million road segments in the US."

I guess they decided to take phrases "computer crash" and "blue screen of death" seriously.

I could only imagine the program modifying GPS directions on the fly:

- Left turn ahead.
- Traffic ahead.
- Please turn right and over the railing
- Please fall 200 feet to the road below and proceed west on highway 53.

Stop Traffic Jams (5, Insightful)

Mikya (901578) | about 6 years ago | (#23023610)

I have a way to help stop traffic jams without fancy algorithms: stop tailgating the person in front of you. That way every time that person slows down slightly you don't have to slam on your brakes, thus requiring people behind you to slam on theirs causing a buildup of cars that aren't going anywhere even if traffic isn't that heavy.

Re:Stop Traffic Jams (4, Insightful)

BlowHole666 (1152399) | about 6 years ago | (#23023648)

Sure if you would just get off your cell phone, get out of the left hand lane and drive the speed limit. I would not have to tailgate.

Sure if you would just get off your cell phone, get out of the left hand lane and drive the speed limit. I would not have to tailgate.
Oddly enough, driving below the speed limit in the left-hand lane doesn't seem to be the problem in these parts. Going faster than the speed limit, especially in the left-hand lane, is another matter... Eeeevery once in a while driving in the left lane I find myself being high-beamed as someone comes up behind me, and I look down and notice, "holy cow, I'm going nearly in the 65 zone - better pay more attention to speed and slow down - wait, there's some guy back there who doesn't think I'm going fast ENOUGH? Wow."

Also, I'm not sure why you need to tailgate cell phone users. Do explain.

Re:Stop Traffic Jams (1)

contrapunctus (907549) | about 6 years ago | (#23024408)

It's just courtesy, if someone behind you wants to pass, leave the left lane for a a few minutes and let him break the law as that is his business.

Mr. Underbridge (666784) | about 6 years ago | (#23023932)

That's true, but reducing the distance between you and the car in front of you does increase traffic density, and thus throughput at a given speed.

Not that it's safe or I'm advocating it, mind you, but traffic flow dynamics aren't a simple thing.

Good. Better to have everyone traveling smoothly at a slower speed and safe distances than to have people packed in at unsafe distances constantly braking and accelerating.

Mr. Underbridge (666784) | about 6 years ago | (#23024406)

Good. Better to have everyone traveling smoothly at a slower speed and safe distances than to have people packed in at unsafe distances constantly braking and accelerating.

Problem is it doesn't work. Where I live, if you leave a nice cushion, someone will move in and cut you off. So what you do is optimize the distance to maximize braking time, which means minimizing the opportunity for cars to cut you off.

Traffic's getting nastier all the time. I try to avoid driving.

Re:Stop Traffic Jams (1, Insightful)

Attila Dimedici (1036002) | about 6 years ago | (#23023984)

I use Microsoft software every day. I wish I didn't have to. When some other company makes something similar I'll look into it, but I have yet to see anything from Microsoft that isn't unreasonable and illogical, with all thought to look and none to functionality.

Knowing Microsoft the thing will probably break if you brake. It won't follow any standards (WE are Microsoft. We ARE the standard!), it will be unreasonably expensive, it will ask me where I want to go today and then take me somewhere else.

I'd rather have a retarded woman back-seat driving. She'd probably be more accurate and functional, too.

Hmm well I have used Google maps on my pda and Microsoft live on my pda also and personally i trust the Microsoft version better. For some reason the Google version thinks performing a U turn is a smart thing to do in a busy city. Try it some time, use Google maps to get to directions and 6 out of 10 times it will tell you to do a U turn and then try the same directions with Microsoft and it will not ask you to do a U turn.

Swings & Roundabouts (4, Interesting)

CmdrGravy (645153) | about 6 years ago | (#23023692)

This sounds like a sensible idea but if it becomes widespread then the metrics it has used for it's monitoring of the traffic conditions are going to change as people choose new routes based on it's suggestions with the upshot that previously clear routes are now congested.

My own journey to work changes based on the time I leave the house and my local knowledge of the area and problme junctions so I can normally make my way down side streets and 'rat runs' without encountering much traffic. The last thing I want is for anyone else to be told these routes and start to clog them up. It is amazing though the difference it can make if you take what is in theory a slightly longer route to get around stupidly placed roundabouts or congested main roads.

I guess ultimately if people had a perfect knowledge of the traffic situation the congestion would even out so everywhere is just congested at rush hour rather than extremely congested but the basic problem, in the UK at least, is that there just aren't enough roads. Here in Birmingham during the recent building work in the city centre there were some traffic conditions which would just lead inevitably to total gridlock as jams backed up across islands causing more jams which looped all the way around town to hold up the traffic in the original jam even more. We just need more roads.

Not enough roads? No, too many cars (2, Insightful)

davidwr (791652) | about 6 years ago | (#23023900)

More precisely: Too many cars at a given time.

There are several ways to solve this problem:

1) build more efficient roads, i.e. better traffic control, better lane design, better/fewer intersections, better signs, etc.
2) build more roads, but only up to a point
3) reduce the number of cars on the road at peak times
3a) reduce the number of cars
3b) spread the load out over time

Mass transit and congestion taxes are ways to do 3a. Getting employers and schools to shift work times is a way to do 3b.

Let's add telecommuting in there. There's nothing about the work I do that requires me to be in the office more than one day a week (aside from the mandate from management). I'm sure many people on the road with me are in the same situation.

Re:Swings & Roundabouts (1)

amplt1337 (707922) | about 6 years ago | (#23024106)

the basic problem, in the UK at least, is that there just aren't enough roads.
Or, alternatively, that there are too many cars.

Anyway, as you've pointed out, what this really is is a shortcut simulator to having good local knowledge of the area you're driving in -- it's a substitute for experience. What they basically have is a complex system that predicts where traffic will be. But what's better than prediction is accurate, current reporting -- and we already have an awesome technology for detecting and avoiding traffic jams, called a "radio." Pretty much every major urban area has at least one station that will give you "traffic on the 9s" or whatever during peak hours.

Now, a real useful service would be a gps with an easy interface (I've used plenty that don't have 'em) that just gives you a map of the local area and shows you realtime updates of the traffic flow (say it colours the streets based on average vehicle velocity). The driver is probably a lot better at making decisions than the computer -- but that wouldn't really have anything to do with MS Live.

Re: more roads vs fewer cars (0)

Anonymous Coward | about 6 years ago | (#23024264)

We just need more roads.

I think you misspelled "fewer cars." In most places, building more roads is not an option (at any cost).

I live a major city in the US, and I take the bus for a 12 mile commute to work that usually takes 16 minutes. In the mornings there are no HOV lanes to help us, so we're screwed when idiots jam the streets. It takes another 10 minutes if it even sprinkles. Ice adds 40 minutes. In the afternoon we get to take a 3+ occupant HOV lane that's almost always completely empty. On on days when the flow backs up past the start of the HOV lane, we have to sit in traffic for another 20+ minutes, but once we hit that point, it lets us literally pass 500 cars in a few miles before the next choke point (yes, I actually counted one day).

I've observed that at least 90% of the cars in my city only have one occupant. If everyone carpooled with at least one other person, there would be close to half as many cars on the road during rush hour. Let's be generous and say 1/3 fewer cars. At that flow rate, there would be no traffic problems. If everyone took the bus, the streets would seem empty.

We just need fewer cars.

I question the way of collecting data. (1)

jellomizer (103300) | about 6 years ago | (#23023700)

They are making assumptions that Trafic Jams around the world/US is the same as Near Redomnd WA. I know traffic in my area on i90/i87 is actually fairly good except for when there is a car accident and often the traffic occures before it can get reported. But down in CT. on i84 and i91 Traffic is always heavy and traffic jams are just from to many cars on the road. Vs. accedents. Also some states have commuter lanes so there may be heavy traffic on the road but you have a couple of poeple in your car so you can take the commuter lane and avoid trafic all togeter. Traffic Patterns varry differently across the country. Just collecting data from people who live in a particular areas may not get good information to make the decision.

Have you ever thought this could be used to monitor traffic congestion during specific times of the day. So if the user is going to be driving between 4:30 and 5:00 PM Microsoft will spit out different directions then it would if the user was driving at 8:00 PM at night.

hmm, does it learn? (3, Insightful)

beyonddeath (592751) | about 6 years ago | (#23023840)

The first thing I thought, and I have thought the idea of analyzing traffic flow on a wide scale could give the individual an edge, as soon as the masses know the way around traffic, the jam will just move. So unless this algorithm can automatically figure out where traffic is stuck, and route the users in many different ways, this will eventually not work. Not to mention that in many cases (ie try entering downtown toronto from etobicoke), there are only so many ways to go. In my example you have some side streets, bloor, eglington, gardiner, lake shore. But they all suck, and if you suggest the small residential roads, you'll probably sit just as long waiting to turn from road to road. I've tried. But if it helps at all its worth it imho, its not my money!

The Unfortunate Fate of Traffic James (5, Funny)

soulsteal (104635) | about 6 years ago | (#23023886)

Aye, 'tis been a while since I heard the name of the Hound of the Highway, Traffic James.

Jim Axelman was once an ordinary man. He had a wife, three kids, even a Labrador retriever named Buddy. But his life was changed forever as he drove to work on fateful day. You see, he was trying to change lanes while talking on his cell phone and jamming out to some Led Zeppelin playing on the classic cock station when he unfortunately cut off a Gypsy minivan-mom. The Gypsy, being a member of the same PTA as Jim, knew who he was and cursed his name to the Heavens. Since that day, he's been forced to drive the streets.

His blinkers never work. If you're in a hurry, he slows you down. If you're not rushed, he tailgates. He can't stop for food or bathroom breaks, his odometer never changes. He forever wanders the Earth in his dark blue Geo Metro.

It's been said that some nights, on an empty country road.... you can still hear the a never-ending play of Kashmir on the wind.

chicago and new york city fare pretty well, but most sprawling american cities have awful rail service. they were built from the ground up based on road transportation rather than rail. this is not good

east asia and europe has left us in the dust when it comes to rail service . while we spent most of the 20th century ripping up what we built up in the 19th century, other parts of the world remained committed to rail or at least let it limp along on life support. the usa pretty much killed rail: ripped up the lines and buried them under suburban subdivisions

but with gas prices climbing, it should behoove those in positions of power to update, revive, or pioneer rail services in major american cities. it's a matter of economic security nowadays, not an environmentalist's pipe dream. due to fuel concerns, environmental concerns, quality of life concerns (remember, this threadjack is under a story about traffic congestion), i think the 21st century will represent a renaissance in railroads

zappepcs (820751) | about 6 years ago | (#23024210)

Where are the details? I've seen several attempts to use such data, and the way that traffic works, the slow-down is clear by the time it is posted to the Internet, and what shows green is red when you get there. Without a tactical HUD and real time data, such things are little more than novelties.

Everyday I drive past one intersection that has a slow down on good days. When there are traffic problems ahead, you cannot tell until you are in the traffic jam already. Normally, it takes 2-3 minutes and you're moving again. Some days it's merely a slow-down. Traffic analysis will never show when that stretch of road is fully in congestion and the only prudent course is to get off the highway.

I don't even care how many volunteers were in the study, modeling traffic has been done before and it does not predict the daily problems that you have to deal with.

Nothing short of a HUD with real time data will help. Well, voice assistance from a system with real time data will help also, doesn't require a HUD.

The point is that modeling won't do it. Only monitoring in real time will do it. Without real time data, by the time you get to the decision point half the other drivers are already clogging your escape route.
