I estimated back during my week long commute on the WES, and even before what the rider levels would be. I was spot on +- about 5 riders per trip.
My original spreadsheet is below (I created this table via Excel back on February 3rd).
| Station | Total Per Station | Drive Up Guess | Riders |
| Beaverton Transit Center | 86 | 15 | 2392 |
| Hall/Nimbus | 76 | 10 | 456 |
| Tigard | 121 | 15 | 760 |
| Tualatin | 201 | 15 | 152 |
| Wilsonville Station | 447 | 25 | 1520 |
| | 0 | | |
| Total For Route | 931 | 80 | 5280 |
| | | | |
| Best Total | 1547 | | |
| My Estimate Total | 1800 | | |
| Reasonable Total | 1238 | My Bet | |
| Optimistic Total | 3000 | | |
Now I'm thinking of doing an estimate for the Green Line to see how close I can get. Of course, the Green line will take a LOT more calculations as the stations are greater, the inputs are greater, and there are tons of bus lines to figure out. On that note, maybe Mr. Rose, Al M, Erik H, or some other want to weigh in with their estimates? If you have any thoughts on what the rider levels will be, please comment, I'd love to have a little unofficial guess work going on. :)
So what are the guesses? I'll narrow it to average riders per day for the first year. Will it be 6,000 per day, 15,000, or 45,000? Let me know!
