The Mathematics of Light Rail

So a new sign went up at my Park-and-Ride yesterday:

Though it's a year or two away, I'd already done some preliminary number-crunching as far as the economics and scheduling of taking the light rail a few months ago:

• The light-rail and bus will depart from the same location;
• The light-rail has nine stops between where I'd be getting on and the closest stop to where I work;
• The bus has two stops, at most, between my boarding and deboarding areas, and frequently has only one, since I tend to walk from the Market Street Station to the office (as noted earlier);
• Once the light-rail's running, the end of the line is two or three blocks further from my office than the Market Street station (though I gather that they'll close that station down in favor of Union Station, where the light-rail will stop);
• The bus has to deal with traffic, while the rail won't.
• The rail will run every 8-10 minutes, I gather, while the bus runs every 30 minutes (though, to be fair, there are 4-5 bus-routes that'd get me downtown within walking distance of the office).

All in all, I'm still kinda on the fence about whether I'll continue busing in, or plan to be on the train. Guess I'll have to wait and see...
