[Electronics-talk] GPS in the Big City

[Larry Wayland]

I like using the gps on my iPhone and think it works as well as any gps I have used, However, I have a question I have wondered about often. Does using the GPS use up a lot of data? If it does this could be a issue with the limited data plans.

The problem with all these GPS apps and devices is that they are designed to simply give you directions for the shortest route between two points, not necessarily the safest route.  If these devices were truly designed with blind pedestrians in mind, their primary route  suggestion, regardless of length, should include only streets with sidewals or walkways that are 
isolated from traffic.    If no such route is available, then they should 
alert you to this fact.  When you use Google Maps to get directions between two points, the walking directions include a warning, if appropriate, that some parts of the trip may involve walking on highways or other areas that might be hazardous.  GPS devices designed for the blind should do the same. 
After all, when you work with an O&M instructor, he will usually recommend the safest route between two points even if it means walking out of your way to get to your destination.
