[OSM-dev] Project Proposal - Waze Integration

[steve brown]

Sorry, phone keeps pressing wrong buttons for me, I may give up soon... but
I think given good client software this could be a valuable project. At the
very least, for any support for temporal restrictions we need something like
this, and OpenSatNav would be able to make good use of this, difficult
algorithms or not. Don't be discouraged.

 Hi Peter,

 Your proposal is interesting, but given the technical challenges you
 will face, it seems overly optimistic to me. I'm also not convinced
 that many people would be sufficiently motivated to manually report
 transient information such as "roadworks here", so I think your focus
 should be on automated extraction of information from live GPS logs.

 I expect that matching poor quality GPS logs (think smartphones) to
 OSM data (without concern for the dynamic nature of this data), and
 generating information with sufficient confidence about missing ways,
 turn restrictions, missing or incorrect oneway tags would already be a
 good challenge. Generating information about traffic conditions would
 be another possibility, but with less direct utility to OSM.

 Concerning the matching of GPS logs, I suggest you read the paper
 "Hidden Markov Map Matching Through Noise and Sparseness"[1] and perhaps
 prior art from the CarTel project[2].
