The frequent bus service, rapid transit lines and commuter rail networks of major cities are what people typically think of when they think transit. Some cities such as San Diego have led the way. San Diego showed its commitment to transit with a new light rail linking downtown to Tijuana.
Many major cities, whose transit systems were considered revolutionary in years past, have allowed stagnation. The bulk of Chicago’s elevated mass transit lines are over 100 years old. While this is a testimony to transit’s sustainability and durability, improvements and expansions are needed. Suburban growth, demographic shifts, and other changes can alter travel patterns and create new needs. In the largest cities, millions of people depend on up-to-date transportation systems whose design reflects current travel patterns. This means updating transit.
Extending lines to emerging communities, removing bottlenecks, and other service expansions are a key need, but that’s only part of the story. Major repair projects, station renovations, and other maintenance projects are necessary for any mass transit system.
