Hi all, attached is a patch that changes parts of the program logic regarding restriction relations to make it more stable and add further plausibility checks. The compiled binary is here: http://files.mkgmap.org.uk/download/198/mkgmap.jar Compared to r3189 it fixes some errors and adds new checks: 1) only these restrictions are evaluated: no_right_turn / no_left_turn / no_u_turn / no_straight_on / only_right_turn / only_left_turn / only_straight_on / no_entry / no_exit 2) to-ways that build a loop so that first and last point end at the via node are now supported if the restriction contains a direction info (left, right,...). 3) Further plausibility checks are performed to find restrictions where the angle of the from and to way don't match the direction info, for example when a no_right_turn looks more like a no_left_turn. 4) Restrictions with multiple via ways are now supported as well as via ways with additional nodes. The new limit is given by the img format: it allows to specify a "path" with up to 8 routing nodes. I've tested the patch with default style and all tiles for Germany, as well as Hennings and Minkos style. I found no more severe error message, and the remaining warnings seem to be correct. Please test this patch with your style and check the log regarding warnings for restrictions, if I hear no complains, ll commmit it on friday. Gerd
