Study: Just Six Tracks Carry 30% of People Across the Potomac (57 Highway Bridge Lanes Carry the Rest)
A new Virginia study (PDF) finds that Metro and other transit operators carry a major portion of all cross-Potomac travel in a just a few crossings, using far less space than the 57 highway bridge lanes that carry the rest. If built, an expanded bridge crossing will need transit to maximize its ability to move people across the river.
Transit’s Role is Critical
While some media outlets focused on the study’s highway expansion recommendation, the presentation acknowledged that Metro, VRE, and other bus operators plays a major role in the movement of people across the river from Virginia to DC in the core of the region. Seeing that, we thought we we’d drill down further to estimate how many people are actually crossing the river, using which bridge, and by what mode. Supplementing the study with available transit ridership data and vehicle occupancy data (PDF), we arrived at the following estimates: Read more…
