relation to MAP/SPAT message? #56

Closed emiltin closed 4 months ago

emiltin commented 5 years ago

1.0.13 added support for time-to-green/time-to-red. what's the relation to standard MAP/SPAT messages?

SPAT must also include data about the signal groups. this is not in the RSMP time-to-green message.

SwarcoPalm commented 5 years ago

If the idea is to generate SPaT/MAP based on the data in RSMP, the main blocker will be latency. RSMP is not nearly fast enough (cleartext large JSON messages) to deliver data needed for a SPaT/MAP interface.

emiltin commented 5 years ago

Are there documents describing requirements regarding latency and throughput? My guess would be that the network type and processing mechanisms is much more likely to generate latency that the fact that JSON is used.

Old discussion, not actionable.
