Stress based route mapping
- Blue -- Paths. No auto traffic conflicts, but limited maximum speeds.
- Dark Green -- Low Stress. Suitable for novice cyclists and up.
Roads: Low traffic speeds (< 25 MPH). Bike
lanes, or low auto traffic volume.
Intersections: Stop signs, stop
lights, no wide/fast crossings, even at lights.
- Light Green -- Moderate Stress. Suitable for intermediate cyclists
Roads: Dedicated bike lane with adjacent high speed traffic (>
30 MPH) speed road, or sufficient lane width that a cyclist does not
need to take the lane. On lower speed roads, cyclists must take the
Intersections: Consistent with roads, or, on a low stress road,
crossing a wide, higher speed arterial with the aid of a light.
- Orange -- High Stress. May be Bikeable, but not comfortable for any cyclist.
Roads: Higher (> 30 MPH) speed road. Frequently must take the lane with high speed traffic.
occasional wide lane, which may be taken by parking. No bike lane.
Intersections: Must share a lane with higher speed auto traffic.
- Yellow -- Extreme High Stress. Do not go here.
Roads: Narrow and high speed. No choice
except to take the lane in > 40 MPH traffic. In Palo Alto
this is Alma and Oregon near the Alma underpass, and the San Antonio
Intersections:Freeway interchange ramps, one lane only.
I am not sure on color / marking. Do not want to
make bad places eye catching on this map. Not using bright Red for
Which Roads are worth marking?
- Roads that cross barriers (Arterials, or train tracks), or make longer connections.
- Assume: Neighborhood streets are Low Stress, unless marked higher.
- Assume: Arterials are High Stress. and mark them if not(??)
