I agree, that would be a good example where the length of way that has its speed/class reduced should be limited. I suspect it will get done sometime but I'm not doing it right now - my mkgmap hacking energy level is depleted, got to wait till it recharges. Still, it's not really a big deal because all it means is that the router will be a bit less keen (if routing for speed) to use that way than it would do otherwise, a speed level reduction of -1 (for example) is not going to make much difference even over several Km. What I was aiming for was a means to add a time penalty for each instance of lights/crossings/miniroundabouts/etc so that when cross-town routing it would, hopefully, pick a faster route. We will see if that proves to be the case in practice. Cheers, Mark
