Estimating the impacts of route changes for Chicago's rapid transit system

The Chicago Transit Authority is the second largest transit agency in the US, and the CTA's rail transit division currently serves nearly half of the rides in the system. The system is adaptable to changes in population and ridership demand: most lines can be run either across the original Loop 'L' elevated lines, or through the mid-20th Century-era subways, with the additional option for lines on the Loop of either running back to their originating terminal or through the downtown to a terminal elsewhere in the system. Ridership has grown significantly in recent decades but the current route structure is not optimized for current demand, leading to portions of the system which are underutilized and others which are overburdened and congested. As ridership has grown, congestion has increased on certain portions of the system, especially on the Loop, where up to 35 trains per hour are run on certain line segments.
