Route Match Extension API Developer's Guide

Real Time Use Cases

Route Match Extension API can also be used for (almost) real time use cases, where short traces from vehicles are matched and feedback during the journey is provided (driver alerts), or the journey is influenced (re-routing). Matching a trace that contains the latest few hundred driven meters provides better match results than matching isolated coordinates. Note that for sensitive matches (alerts or rating penalties), the end of the trace (last points) sent to Route Match Extension API should be disregarded from the result, because they are missing future points for sufficient match quality.
