Microsoft Finds GPS Tracking Tech Can Reduce Traffic Jams
New research from Microsoft Research Asia (MRA) shows the cause of traffic jams. “Congested road segments are only the appearance—they’re not the problem,” says Yu Zheng in a report from MIT, who led the research. “We try to identify the true source of the problem in our work.”
Microsoft (MSFT) scientists used GPS tracking data from thousands of taxi cabs in beijing to determine where, when and why areas of the city became congested. MRA has shown that tracking the location of taxicabs could be a better way to identify the underlying problems with a city’s transportation network, helping officials determine how to best ease congestion.
The researchers used GPS data from more than 33,000 Beijing taxicabs. That data was collected in 2009 and 2010. The researchers were not just looking for bottlenecks—trouble spots that regular commuters may know only too well.
