OSMAND TRAFFIC ANDROID
The abstraction layer makes the ecosystem of traffic data sources independent from the apps used, thus multiple apps can use the same ecosystem.Īs of now, there is only one live data source: Qz, an Android app, which receives TMC data (requiring an external FM/RDS tuner), converts them to TraFF and forwards them to consumers. There is also a Java library for the TraFF object model, which I could expand to parse TraFF data in XML format. I can provide some first-hand experience on processing TraFF data on the data consumer side.
OSMAND TRAFFIC UPDATE
As there is a standardized exchange format, there is no need to update the consumer app when new sources become available. ĭata is provided by external apps consumers (Osmand in this case) only need to add the capability to receive and parse TraFF data and translate it into their own data model. More information on the exchange format is available at. At the core, there is a generic exchange format, with a logical data model loosely inspired by TMC, and locations expanded to WGS84 coordinates. I have been working on something like that over the past years.
OSMAND TRAFFIC FOR FREE
Don't know how exactly this works, but maybe Osmand could use that source for free when they participate in data collection. Unfortunately, I doubt that this is open data. It looks like Mapbox offers a traffic data service now that's usable for OSM-based apps. But as stated in the other issue, the OpenTraffic initiative did not succeed (yet?!).
we 😛 ) needs is an open data source for traffic information where everyone can participate. not necessarily structured) and lacks sufficient coverage. "Public" information from FM station's websites on the other hand is rather inaccurate, not perfectly machine readable (i.e. This gives them the advantage over competitors like Osmand to have great traffic information available. Google for example collects its own traffic information utilizing the mass of Android phones with GMaps installed out there. However, that's not how it is as of today. Ideologically you are right that this information should not be private property. After all: these information can be seen by anyone who is looking at the corresponding streets, so how could those information be private property? Ans on the contrary, the spreading of these information is in everybody's interest, isn't it? So, I would guess, these information are neither top secret nor anyone's private knowledge.
