Re: Sign if you agree. RE:bus stop spacings

So much wrong with this.

Yes, but buses traveling 25 percent faster doesn’t save you 25 percent of the time.

Buses traveling at 8.5 mph for 2.3 miles equals traveling at .141 miles per minute so traveling 2.3 miles takes 16.31206 minutes.

Buses traveling at 10.5 miles equals traveling at .175 miles per minute so traveling 2.3 miles takes 13.14 minutes so you save three minutes, not four.

This is a nit (because the difference is small), but the difference of 2 mph is not 25% of 8.5 mph. 2 mph would be 25% of 8 mph. Corrected calculations:

8 mph / 60 minutes in an hour = 0.133 miles per minute
2.3 / 0.133 = 17.25 minutes

10 mph / 60 minutes in an hour = 0.167 miles per minute
2.3 / 0.167 = 13.8 minutes

You save 3.45 minutes, which is 20% of your original trip time.

If you walk only one more block to the bus stop, and you can do so in one minute, you only save two minutes provided you don’t miss a bus while walking which could add ten minutes to your trip.

If you walk two extra blocks, you only save one minute.

With buses stopping every other avenue block, your walk increases by 750 feet or three city blocks. So the three minutes saved is cancelled out by your three minutes extra walk and you have an even greater chance of missing the bus.

These categorical statements (especially the last one) assume that everyone who's affected lives or works exactly at an eliminated bus stop, resulting in the maximum additional walk. Many people don't live or work immediately adjacent to a bus stop, so their additional walk will be smaller.

Additionally, anyone who's concerned about the marginal time losses you're presenting and isn't using BusTime or a similar tool to figure out when to head for the bus stop, eliminating excess waiting time, is an idiot. (I suspect many, perhaps most, people aren't concerned about these marginal losses.)
