We all know improving station access is good.  But, how do we rank access projects relative to each other?   Step 1: Ridership

In our recent post, we gave you an overview of our Station Access Investment Strategy project.  We’ve identified 1,000s of recommendations for new pedestrian and bicycle infrastructure near our Metrorail stations and need a way to prioritize them.  After some thought, we’ve come up with a number of potential criteria.  In this post, we’ll discuss those that deal with ridership.

Once again, one of key concepts we’ve been telling you about in recent months is that by improving access to stations we can grow ridership.  For stations with relatively small walk sheds, we’ll conduct a detailed analysis of what happens to the walk shed when the proposed projects are built.  For example, add a sidewalk at Cheverly and the walk shed will grow by X%.  We will then look at the amount of households and jobs in the newly connected area and, using some methods we’ve shown you in other posts, calculate the potential ridership gained by the new project.  The higher the potential ridership gain, the better the project scores.

But, we also want to understand the value of a new project to a part of the station that is already connected to the network and how this could relate back to ridership.  To do this, we’ve come up some other metrics.  They include: Read more…
