Light Rail avoids congestion. It runs on electricity. Light Rail is therefore quiet, and does not emit harmful pollutants. The schedule is dependable. Unlike buses, which are subject to traffic and boarding delays, light rail runs on a dependable schedule that gets people to their destination quickly.
Stations can promote quality development.
Because planners want easy pedestrian and bike access to stations, development around the stations is designed for neighborhood compatability. The bus system benefits. Buses act as feeders for light rail systems, and thus they would enhance crosstown routes for Austin. I think for me personally, light rail is going to save time and energy, especially in getting downtown to th Capitol, the Children's Museum or to big events. Now we can go together as a family and not have to worry about parking or traffic.
