Anyone who relies on the bus to get around knows how important it is to be able to fine-tune your journeys, especially when you're trying out different routes. Now you can find out if your bus is running late, by clicking on "routes and schedules" at RTD's nifty informational Web site. If your bus is delayed by over five minutes, it'll be noted, and you can plan accordingly. RTD boasts that it's one of first transit agencies in the nation to provide such a service. Whether your bus itself is on time is another matter.
