My plan is to generate a set of LSOA-to-LSOA matrices covering:
a. A drive-time matrix (this won't take account of variation incongestion or anything like that, so nominal departure/arrival time are largely irrelevant).
b. Travel-time matrices based on a small (3-5?) set of depart-after times.
c. Travel-plus-waiting-time matrices based on a small set (again 3-5?) of arrive-by times.
For the sake of easier explanation, I'm going to use the following LSOAs as examples:
