criteria
50 km/h limit
Consider 60 km/h or 80 km/h if lesser
degree of development or engineering
measures not practical or cost effective
60 km/h limit if strong environmental
reasons or considerable VRU usage
60 km/h limit
100 km/h limit
60 km/h limit (or if
recommended route for
VRUs)
80 km/h
100 km/h limit if mixed function (best quality roads only)
