Per game. Still it is a weird design choice for something where you need a lot of people to move at the same time. They need to decrease the distance of the skates, chain them together or get bigger ones. Automatic people movers are nothing new, but if this is what it takes for the US to be excited about infrastructure then I am all for it. Half of the utility if these types of systems tends to be in the overall design though. The interior of the vehicles, the location and design of the terminus, how long you have to wait etc.
