Richard J. Pope invented a bicycle barometer that tells you whether today is a good day to ride or if you’re better off taking transit.
The bicycle barometer takes the data about the weather and the status of the subway, and reduces it down to a single value, determining whether it’s better to ride or take the subway.
It displays this decision in a most simplistic way – a simple dial with a bike sign to the left and a subway sign on the right.
So if it’s raining for example, the dial will move a bit toward the subway sign, but if the subway is experiencing delays, the dial will move a bit back in the bike direction. Different data points get different weightings, e.g.: snow gets a bigger weighting than drizzle.
