The document proposes improvements to TriMet's trip planning tools to better support accessibility for users with mobility devices or disabilities. Specifically, it suggests: 1. Mapping walking paths near transit stops in more detail with sidewalk and curb cut data. 2. Assigning accessibility ratings to stops based on amenities like ADA landing pads and pedestrian crossings. 3. Enhancing the user interface with new features like a disability preference triangle, travel speed slider, and elevation charts to provide more customized, accurate routing options.

1. Walk/Wheel to Transit with
Old Trip Planner
(ride.trimet.org)
Steep, high traffic road with
no sidewalk or shoulder

2. Walk/Wheel to Transit with
New Trip Planner
(rtp.trimet.org)
More detailed itinerary and walking path
Routes to Bus 54 instead of Bus 51 for
shorter more direct walking path
2

3. Ideal Curb Cut and Sidewalk Mapping
108,000 blocks/streets in TriMet service area
with 2 sidewalks & 4 curb cuts per block
Conservative assumption of 80% sidewalk
coverage would entail mapping 172,800
blocks of sidewalk and 345,600 curb cuts
Grant of $9,600 - strategy is not a viable
option
Maintaining this dataset is a significant task
Solution – focus on transit stops
Process Benefits
1. Map walkways near transit stops 1. Safer and more detailed itineraries around stops
2. Verify and enhance stop information 2. Enhanced stop amenity information
3. Assign accessibility ratings to stops 3. Users will be directed to stops with better

accessibility

4. Proposed Stop Accessibility Ratings
Category 0 - only sign/pole Category 1 – plus sidewalks & curbcuts in
area
Category 2 – plus ADA landing Category 3 – plus traffic signals, lighting,
pad, seating/bench, shelter
