That’s my point. It needs to be ramps, and the ramps need to go in the direction people are going anyway. This way using the bridge is just a matter of taking a hill at a different point than one would staying on the ground and it’s not a detour.
If stairs or an elevator are involved, it’s a detour. In some circumstances this might be OK, but not in general as a replacement for a traffic light.
At University it would help if the lights were motor vehicle activated rather than button activated. The lights could be green for the path until a vehicle comes, then turn. I’ve mentioned it before: two sets of sensors in each direction, one well in advance of the crossing so that in low-traffic conditions the light is turning green just as the vehicle approaches the crossing; and another right at the crossing so vehicles can’t get stuck at a red that never ends. Lights would only be green for vehicles when vehicles are there (subject to a maximum, of course), resulting in much more green time for the path.
