Maintaining the existing transportation network and improving state of good repair are substantive priorities of ON TO 2050. In particular, recent investment in the transit system has been insufficient to keep system condition from declining. This indicator has three separate components.
This measures the percent of active revenue public transit buses that have exceeded their useful life. This represents the number of vehicles that have reached an age where maintenance cost and vehicle performance issues are likely to increase.

This measures the percent of transit rail track with performance restrictions. The CTA refers to these as “slow zones”, where trains are required to operate at slower than normal speeds. This could be the result of construction, power systems, signals, or other issues. Elimination of slow zones can help to make transit more competitive by decreasing travel times and improving reliability.
