The engineer's job at an intersection is to read what's there, then design for all of it.

Context-sensitive design is a literal instruction. Look at the corner. A transit station says: prioritize pedestrian crossing time. A school says: eliminate turning conflicts at arrival. Residential says: shorten crossing distances. The street is telling you what it needs. Pay attention.

Walkshed, not drive-shed. That's how you measure whether a school serves its community.

Schools built on the suburban fringe chose cheap land over walkable siting. If students can't reach school on foot because it's too far, that's a siting problem. If routes are dangerous, that's a design problem. Both are fixable - but only if you measure the right thing.

NYC mixing zones: cars cross bike lanes upstream before signals. I prefer full protected intersections with islands and separate bike signals. Design philosophy matters at conflict points. #MrBarricade #BikeInfrastructure #StreetDesign #UrbanPlanning #CompleteStreets
San Jose's Better Bikeways: phase 1 paint, phase 2 posts, phase 3 tack-on curbs, phase 4 full buildout. Infrastructure evolves. Watched it from striping to concrete. #MrBarricade #BikeInfrastructure #UrbanPlanning #CompleteStreets
Old railroad geometry at Bird Ave and Willow St creates dangerous off-intersection crossings. Protected intersections bring trails into actual crosswalks where drivers expect them. #MrBarricade #BikeInfrastructure #SafeStreets #UrbanPlanning #CompleteStreets
Paint and posts make crossings safer near schools: shorter distances, more visibility, slower turns. California law clears 20 feet for parking near crosswalks. Quick-build safety. #MrBarricade #SchoolSafety #TrafficCalming #CompleteStreets
Two-stage turn box: cross straight, stop in green box, cross again with next signal. No merging across lanes. Safer, less stressful for all rider ages. #MrBarricade #BikeInfrastructure #CompleteStreets #UrbanPlanning
Tack-on curbs: drill dowels into asphalt, extrude concrete, keep existing drainage intact. Cheaper than full rebuild, more substantial than paint. Smart middle-ground for bulb-outs. #MrBarricade #PedestrianSafety #Infrastructure #CompleteStreets
Uncontrolled crosswalks come in layers: paint, curb ramps, yield signs, flags, RRFBs, HAWK signals. The right tool depends on speed, volume, sight distance. Safety design, not one-size-fits-all. #MrBarricade #PedestrianSafety #UrbanPlanning #CompleteStreets
