Sometimes, Automatic Scripting Errs

One of the many problems plaguing crowdsourced traffic data are the errors. Part of this is due to Google partnering with Waze, a mobile app that crowdsources traffic data from users on the road. Sure, Interstate 5 is a very long freeway and it spans across the western US coast. Given the masses of regional data that Google has at its disposal, one would think that having a traffic incident related to the King County metro area wouldn't show up in the Portland/Clark County metro area, 170 miles away. Why this incident shows up at the Washington/Oregon border is anyone's guess.

In the Waze smartphone app, users can indicate the speed and flow of the route they are currently on. An incident happening on I-5, might not actually be in Seattle but be somewhere on the Portland portion of I-5. For example:


2015-01-20, a Seattle incident reported in Portland
