#Navigation apps are great for visitors and commuters alike. You can't beat getting nearly instant traffic information and rerouting. However, these apps are only as useful as the accuracy of the information in them. The City of Austin Transportation Department does a great job of listing upcoming closures for major #events (see reference URL).
Unfortunately, closures aren't always communicated to the navigation systems accurately. During SXSW this year, the closures for entrance and exit ramps to I-35 at the Cesar Chavez and 3rd-8th Street exits were missing. Many visitors, locals, and even our ridesharing drivers were unable to rely on the accuracy of the directions from these apps. I saw so many people slow down traffic significantly by attempting to take these exits.
The Transportation Department needs to take on the responsibility of not only posting these closures, but communicating the information to major navigation applications and devices, and checking the validity of existing information during major events. Let's make sure we're doing everything we can to prevent traffic delays from planned closures.
