<o:p></o:p></p>
<p class="MsoNormal">In some situations, especially on off-ramps, there isn’t any speed limit sign at the beginning of the link only at the end of it or in the middle. I observed that in these situations the speed limit of the motorway is added on the first
part of the link. Because this is the predominant way of adding speed limit on links, we will map in the same way: if there isn’t a speed limit sign at the beginning of the link we will add the speed limit of the motorway and other speed limit that occurs
along the link. If there is a speed limit sign at the beginning of the link (e.g.SL60 in our example) we will add the speed limit in the way you mentioned (60 then 100).<o:p></o:p></p>

<p class="MsoNormal">In Qld at least (& I think Aust-wide) speed limits officially change at the sign - you may start accelerating as you pass it, not before; but you must start slowing early so you're at the lower limit as you pass the sign.<o:p></o:p></p>
