These tags expect an integer value, optionally preceded by a + or - which make the adjustment relative to the original value.
This is a good idea. But I think it would be better to allow for non-integer values of adjustment. E.g. if I have a long street through a city with 10 traffic lights I don't want it to end up with a road_speed of -8. This might route me through small narrow side streets. A correction value of "-0.1" for every traffic light might be better. The value can be rounded to the nearest integer after all corrections are applied. Another suggestion: Add the possibility to mark a road with a minimum and maximum road_speed it can ever get when being corrected in the above way. E.g.: highway=primary [road_speed=4 min_road_speed=2 max_road_speed=5]
