>We are well aware that GTFS accuracy is not perfect. (Though nobody Reported a 100-meter deviation so far). A potential solution, which could also work globally, is discussed below.
Some University researchers who were looking at the GTFS files noted the problem sometime ago in the US. One provider was a couple of hundred metres out on bus stop location. Locally they were a little better but it was only when the bus announcement system came in and they very very carefully measured the location of each bus stop to comply with the provincial instructions that the GTFS file became at all usable and even then it took a dedicated team to do it and it wasn't a straight import. Personally unless you can confirm the accuracy of the bus stops my feeling is no data is better than poor data that cannot be trusted. Please do not do this globally. Cheerio John
