I have been asking MCDOT to look into something like this to report pedestrian problems for a while now. It would only take a few reliable pedestrians with smart phones to asses a great deal of the pedestrian transportation system in a given area. A pedestrian safety app could utilize both the camera and GPS of a smart phone in conjunction with a brief description to notify MCDOT and SHA when there is a problem.
In June of 2008 I organized a pilot project test of PDAs used to gather pedestrian and cyclist conditions in downtown Silver Spring and East Silver Spring. While the data was not comprehensive, the 8 teams of two volunteers gathered more than 200 data points in under three hours. There data was a snapshot, but a continuously-updated, smart phone-based system could keep a running tab on things - including conditions at night, during inclement weather, and during construction.
Something akin to what I have set-up on Google maps could be used to collect data. The ability to overlay data from different sources could help MCDOT and SHA pick-up on formerly unseen patterns.
I have no idea what something like this would cost to maintain. The technology is off-the-shelf. Social media could play a major role. No training for the public needed. Include this in subsequent Street Smart campaigns. The possibilities are numerous...
