Q: I can’t find the Traffic view on my Today screen anymore (the one that shows up when you pull down the Notification Center). It usually comes up right below the weather report and tells me things like how long it will take me to get home from work, but not anymore. When I go to “Edit” my today widgets, I’m pretty sure “Traffic” used to be a separate line, but it’s not even showing up there. Any ideas on what I can do to bring it back?
A: The built-in “Traffic” feature on iOS is a little bit tricky, as it’s supposed to work automatically in the background, but does depend on a couple of other settings in order to work. Since your iPhone bases traffic data on the time of day, where you are, and your previous habits, the actual information won’t always appear — it’s dependent upon the iPhone “learning” your normal routine and deciding that you are normally likely to be going somewhere at the point at which you’re looking at it. That said, if you normally commute to and from work every day, it should at least be showing up at the beginning of the day and the end of the day.
Further, regardless of whether it has any information to show, you’re correct that the “Traffic” line should normally appear when editing your Today Extensions, so that you can at least choose whether you want to see it or not. If it doesn’t appear anywhere on this list, there are a couple of things you can do to bring it back.
First, since Traffic is based on background monitoring of your traveling habits, it requires that Location Services be enabled in general, and specifically that you’ve turned on “Frequent Locations.” These options can be found in your iPhone Settings app under Privacy, Location Services, System Services. If “Frequent Locations” is disabled, your iPhone won’t know where you’ve been, and therefore won’t be able to determine where you’re likely to be going. Note that the “Routing & Traffic” option in this section doesn’t need to be specifically enabled to get traffic — this option simply determines whether you want to send traffic and route information to Apple while you’re navigating to improve the back-end Maps data for other users.
If this option is enabled and Traffic still isn’t appearing, one other way you can give it a kick is to go into the Apple Maps app and toggle the option to “Show Traffic” on your map view. While this isn’t technically necessary, it does sometimes help to “wake up” whatever background service is used for traffic tracking, and is often enough to make the option reappear if it’s gone away on you.
