Microsoft Mines Brains Of Chinese Taxi Drivers
It’s a well-kept secret, which will give the willies to people who are (at least publicly) worried about intellectual property: Microsoft has one of their best R&D centers in China. Located in the silicone gulch in the north of Beijing, MSRA (Microsoft Research Asia) is working on advanced technologies, mostly in the visual area. I worked with them once, and they are NFSWing good. They just had another great idea: Why not mine the knowledge of cab drivers when it comes to proposing the best route on your in-car navigation system?
Navigation systems usually provide two types of directions: The shortest-distance route, and the route that is fastest based on the length of the road and typical vehicle speed. Some augment them with real time traffic information – with mixed results.
“When selecting driving directions, taxi drivers usually consider multiple factors including distance, traffic flow and signals, direction changes, and the probability of accidents,” Zheng Yu, a researcher at Microsoft Research Asia (MSRA), told China’s Global Times.
So MSRA put GPS devices into more than 33,000 of the 80,000 Beijing taxis, and collected the data over three months.
“On average, 50 percent of our routes are at least 20 percent faster than the competing approaches,” says a report of by the MSRA. Earlier this year, an IBM survey had found that Beijing has the worst traffic in the world. At least Microsoft is doing something to get around it.
You are probably thinking the same as I did: What if all people suddenly know the hidden shortcuts? Microsoft thought of that as well. The taxi-based system, dubbed “T-Drive,” will dole out routes that try to balance the traffic.
Here’s an idea for MSRP: For their “T-Drive Ultimate,” I offer the data produced by a gizmo in my driver’s car. He (ab)uses bike lanes, bus lanes, takes shortcuts through hotel driveways, and sometimes goes down a one way street in reverse. I never missed a plane.

- HotRod The Tunnel Turn at the "Tricky Triangle" (Pocono Raceway). I got to push a Nascar-style Dodge Intrepid harder than I ever imagined. I was miserable with shingles at the time, making the experience that much more memorable. But for a handful of laps I didn't feel anything but pure adrenaline.
- Redapple2 That is one busy face. Ford: Too much.
- SCE to AUX The video in the link is pretty damning, but the fix should be a simple mechanical repair. A code patch won't do it.
- SCE to AUX I get it, and yet I don't. Time has put a lot of distance between the 1964.5 and the 2025, and Ford has already sullied the Mustang name by putting it on a vehicle completely unrelated to this one.I guess 1965 somebodys will see fit to pay Ford and its local dealer a hefty premium to 'celebrate' the Mustang name.Are the 30th Anniversary Mustangs worth a nickel today? Better yet, how about the 10th Anniversary Mustangs?
- SCE to AUX Oddly, my 22 Santa Fe has higher HP and torque from its 2.5T/8DCT drivetrain, but it has similar fuel economy (22/28).Must be a different ECU tune for the Elantra N.

There should be a significant flat fee to take a cab. There would then be an incentive for the cab driver to take the fastest route since he would need to maximize the number of clients to maximize profits. He would also increase the number of tips from clients.
I spent a few months working as a parts-and-packages shipping/delivery/pick-up guy for a construction equipment dealer in south Seattle. Believe me, I knew all the shortcuts right down to which ones worked on which days and at which times of day. Guys with jobs like this would be a better bet for generic quick ways about town. Otoh, my destinations were somewhat limited...other parts houses, bus stations (in 1961 we were still shipping a lot of stuff by Greyhound), the main post office, one freight forwarder on the waterfront where we shipped parts bound for Hawaii or Alaska by boat fairly frequently. Speed was always important in that business. Construction guys or loggers need to have their equipment working so they can make the payments on those expensive machines, and if they don't get their parts as promised they're likely to come in and go right over your desk.
