Good news is you can even overlay screenshots of Google Earth (which uses high-res data, some of it at 30 cm2 per pixel). Will take some fiddling with the coords, but it works!
Yup, we’ve got a big list of mods to help alleviate some of these issues. Due to the way we’ve modeled the corridors and daily population flow in and out of the city, we still get roving herds of ambulances…
Depends on how much of the games underlying assumptions you can overwrite, and of course the fidelity you’re going for. In our case we’ve modified everything from citizen lifecycles to traffic behaviour to population calculations based on square footage - but this is still more in the realm of “visualization and communication” than “professional planning tool”.
Typically you look for its use in both academia and in the field (hence CUBE, for instance; widely used by the academics at Moratuwa who then go on to work on actual projects)
We see broadly the same chokepoints (Galle Road, Baseline Road, the arteries feeding into Colombo). Modify these and the chokepoints distribute themselves. Small chokepoints don't always appear.
