Combining the Trimet datasets/services with the datasets pertaining to curbs, sidewalks, and slope/elevation would allow a user to plan an "accessible" trip.

Walking or otherwise traveling to a station that's technically the closest one may not be the best option if it's a 50ft elevation gain or the travel path has no sidewalks or curb ramps.

The solution is a front-end to the TriMet trip planning services that picks the best routes and walking paths for those that are in a wheelchair, walker, scooter, or would simply prefer not to hike up a hill if it's not necessary.

Evaluating a series of available routes and weighing them based on the user's preferences - elevation, sidewalks, curbs, etc - would be a fairly straightforward task.

This could also be useful for those traveling with children that don't want to walk along the edge of streets with no sidewalks.

Hi, I'm the developer of ADA PDX (http://adapdx.com) I have been looking into routing algorithms and this is a very difficult problem to solve. However, I would like to attempt to come up with some sort of routing solution. I'll keep you posted on any ideas I have
