This map shows how many people are riding transit (volume) and how crowded it is in 2015 and 2050. The width of each line represents volume and the color represents crowding. These estimates are summarized to stop-to-stop transit segments, which may be served by multiple transit lines.
On most transit vehicles, crowding level 0.5 usually means most seats are occupied and some passengers may be standing. At 0.85, standing passengers are close and passenger movement is restricted. At 1.0, it is difficult for additional passengers to board. In this visualization, crowding is represented as an average across all of the individual vehicles in the time period, so some vehicles may be more or less crowded.
