If unspecified, 'exit' would mean 'exit right' to the right side of the traffic flow. In dense urban areas it might make sense for geography or cost reasons to put it on the left in which case youll see "Exit Left" to make sure people know to be in the 'fast lane' in preparation to leave the highway since it departs the highway exceptionally on the left
I-94 and I-35E in St. Paul, Minnesota comes to mind. You just merge left onto the other highway if you need to change.
While (relatively rare) left-hand exits are a thing in the US, I don't think that's what the arrows on this app is showing. The screenshot appears to be showing a single exit.
The arrows probably tell you whether your first turn will be a left or a right immediately after leaving the interstate. Many exits have two lanes, one for left turns and one for right turns onto the connected surface street. You have to know which exit lane you want to be in.
On a road trip, gas stations and fast food to the "right" of your travel direction on the interstate are slightly preferable because you don't have to wait for any left-turn signals. The US allows you to turn right at a red traffic light as well, saving even more time.
In US highways the exit ramp off the road is usually on the right, but is some cases the exit is on the left, especially in areas where the highway is elevated or in crammed downtowns. The left lane is also usually the “passing lane” and cars drive faster than on the right, so if there is a left exit and you’re cruising on the right line, you have to know in advance to safely move over to the left
Very nice app, btw. Thank for you creating and sharing it. We have the same issue with our family, we want to stop but don't know what's coming and if we should wait for something better or not. So the non-driving person is in charge of scouting ahead on their phone on the map for restaurants and gas stations.
I think with the left vs right, it might be just a regional / cultural thing. Left exits are frowned up or just not allowed and many places (and for good reason) so people may not be familiar with them.
Hey!
I am master student at the technical university in Vienna and trying to finish my thesis until fall.
I have worked intensively on downstream LLVM backends and
I would be looking for a compiler/vm related job.
I am working on my master thesis. My research group has developed an architecture description language and I am generating a LLVM compiler from this specification.
In Austria, you have usually one exit. Alternatively, there might be a roundabout.
