How To Present Information  
Suppose that you are designing a system to present information on a display that can show a screen of maybe 10-15 words worth of information at a time. Which of these timing patterns do you use to rotate items of information through the display?

TIMING PATTERN A:
(Item #1 relevant to about 1% of your customers)
(Item #2 relevant to about 1% of your customers)
(Item #3 relevant to about 1% of your customers)
. . . . .
(Item #9 or #10 or #11 or whatever relevant to about 1% of your customers)
(Train Schedule Info relevant to 100% of your customers)

or

TIMING PATTERN B:
(Item #1 relevant to about 1% of your customers)
(Train Schedule Info relevant to 100% of your customers)
(Item #2 relevant to about 1% of your customers)
(Train Schedule Info relevant to 100% of your customers)
(Item #3 relevant to about 1% of your customers)
(Train Schedule Info relevant to 100% of your customers)
etc.


If you answered "B" -- sorry, there are too many digits in your IQ for you to be employable with the Washington Metropolitan Area Transit Authority.

I dunno...seems to me the train schedule info should be repeated to give people a chance to memorize what they need of it. They may not have time to wait until after items 1-N of 1% relevance go by before the next replay of the schedule. And if the schedule info's display interval is too short, they may need it. ("Wait! What time was that second train again? That went by too fast!") So Timing Pattern B makes more sense to me. Of course, I hate waiting in general, so I may not be the best person to ask.

Er, that's what I said, in my sarcastic oblique way (i.e. the dimwits in charge of Metro run Pattern A, with a long list of elevator outages and shuttle service info from adjacent stations with working elevators -- necessary info for people who can't get off the platform any other way, but it's just stupid to do the whole list between showings of the train schedule info that is relevant to everybody).

At least they display schedule information. The MBTA commuter rail just says "Trains on or near schedule," until it becomes painfully obvious they aren't.

Guess I shouldn't be looking for a job with WMATA anytime soon. :(

Ah, WMATA. Some things never change.

Darn that 3-digit IQ. It keeps getting in the way.
