How Taxi Drivers Are Helping to Create More Efficient Driving Directions
November 10, 2010: Microsoft is using the collective wisdom of taxi drivers to improve its online map directions. The study used GPS data that tracked over 33,000 cab drivers in Beijing over a three month period to learn the subtleties of navigating through a major city to get around driving headaches such as congested roadways and traffic signals. “These factors are very subtle and difficult to incorporate into existing routing engines,” says Yu Zheng, a researcher at Microsoft Research Asia. The approach is called T-Drive , and is the collaborative effort of Yu Zheng, Jing Yuan, and Xing Xie. The authors are presenting their methodology at this week’s International Conference on Advances in Geographic Information Systems, in San Jose, California.
The system was tested against traditional online map directions which provide time estimates based on the posted speed limits and some limited traffic information. The study field-tested the T-Drive directions against online mapping providers. The study found that 60% of the routes suggested by T-Drive were faster than routes based on posted speed limits. The study found that for each 30 minutes of driving, T-Drive saved the driver 5 minutes compared to traditional online mapping directions.

Microsoft’s Bing Maps
Microsoft’s Bing Maps allows for driving directions either based on shortest route or shortest distance. Also handy is the ability to toggle back and forth between calculating distance in miles or kilometers. Microsoft has teamed up with Pictometry to offer oblique aerial views so once you map a destination you can toggle back and forth between the “map view” and “bird’s eye view”.
