I'm currently working on a methodology to investigate the effect of taking one car away from a two-car (or more) family. It's hypothetical, we won't actually take a car off them, instead we'll get them to keep travel diaries and vehicle logs for maybe a week, then map out their activities and the locations of those activites, and ask them to figure out how they'd get to where they need to with one less car.
I guess some of their options would be
a) ride share
b) take public transport
c) walk, cycle or skateboard (non-motorised individual transport)
d) cancel the activity
e) delay the activity
f) reorganise other activities
The idea is to investigate whether putting restrictions on car ownership may actually lead to less efficient travel and higher VMT (or VKT here).
My question is this: does anyone know of any software (or just clever ideas!) that we could use for visually mapping peoples' activities by location and time, to enable us to use as a discussion point with the participating families, to see how their travel would change.
An interesting project....
