    Same problem addressed architecturally. Aesthetically appealing, but not sure if dangerous. Robson Square. Vancouver, British Columbia, Canada.

    A whole lot less dangerous than that tracked wheelchair contraption if a gear breaks or those cylinders lose pressure while climbing steps.

    I don't know how architecturally. Aesthetically appealing I would call their solution. But I would most defiantly class those stairs as a health hazard.
    I count at least 2 dozen possible toe stumble points. At no time should any tread ever extend above ant landing either horizontal or inclined thereby creating a possible place where a persons toe or heal of their shoe may be caught . All of those treads should have been ground away to the same level of the inclined ramp. Additionally most safety codes require a handrail to be within a persons extended reach from any vertical assent or decent path of a stair . this would mean that there should be at least 2 additional sets of handrails going up the stairs.
    As for the tracked chair that looks like a variant of the one a man by the name of William Robertson of Robertson machine was developing before his cancer overtook him in the early 1990's
    The thing he was working on had a positive lock ratchet to the tracks in case of some mechanical failure. and his cylinders were electric linear actuators ( screw jacks if you will).

    Not sure why they didn't taper the ends of every trip point to the angle of the ramp? It wouldn't negatively impact the stairs or the ramp and it would eliminate all of the trip points
