I’m working on my master’s project about bike parking distribution and equity in Chicago and while working on a section in the paper, I decided to get some help from readers. Many transportation projects are measured on predicted changes like trip travel time savings or trip cost savings (I give two examples below the photo).

My question is this: What are a bike parking installation’s measurable benefits to a traveler or a community?

To figure equity (fairness) for these project types, you measure these impacts for different groups (often high, medium, and low income), either in the alternatives analysis, or project selection phases. So, converting a lane on a highway to charge tolls for the lane’s users will have a certain benefit for many trips: a lower trip time. A new bus route may be convenient enough for some travelers to switch from driving to taking the bus, possibly reducing their trip cost.
