The first thing (posted Wednesday night) is adding emergency and pedestrian turn exceptions. Disabling emergency and/or pedestrian systematically is two bits in an existing byte so it will not change the size. Disabling other types of vehicle on a systematic manner, would increase one byte per restriction. Depending on usage it can be interesting: I personally use my car map for short ped routing and would love to be able to disable turn restrictions in that case. The second one (posted Thursday evening) is much more interesting and allows via ways in restrictions. Has I said yesterday there are some know issues mainly because I did not get the full extent of the NOD file encoding. One thing that I forgot yesterday is that the turn restrictions are duplicated for now. I guess some sort of logic would allow to keep only one version of each of such restrictions. Regarding your suggestions of toll roads and others depending on vehicle type, I do not know if this is possible at this time. Thanks, N.
