"Normal Sequence" The last definition wrt transit is 'normal is what the signal does when there is no bus' Since we are discouraged to deviate from normal, what does that mean?21 May 2026 20:05 +0000at://did:plc:zvbvhvbfsik2unri5raxegff/app.bsky.feed.post/3mmf7rpiwtc2nhttps://bsky.app/profile/jerryschippa.bsky.social/post/3mmakwsqjv227Hansa Teutonica up first at Starkweather Brewing.

Recently in an effort to try and figure out some performance metrics I came across some interesting datapoints from signal delay, stop delay, percent of signals stopped at...and also alignment.19 May 2026 01:19 +0000at://did:plc:zvbvhvbfsik2unri5raxegff/app.bsky.feed.post/3mm67wftfxk22https://bsky.app/profile/jerryschippa.bsky.social/post/3mm4whcfwcs26Tracked my ride in this morning. I've measured an average of 35" signal delay here on previous rides. We had 5" and reviewing yesterday's runs we averaged 17". But uh, 56% of signal delay from 4 state signals! 😬 [contains quote post or other embedded content]18 May 2026 12:57 +0000at://did:plc:zvbvhvbfsik2unri5raxegff/app.bsky.feed.post/3mm4whcfwcs26https://bsky.app/profile/jerryschippa.bsky.social/post/3mm3gcl5zvk2oUpgrading my bike tour gear.

Replace loops with new non-intrusive detection that has vehicle classification abilities and its just a matter of political will. Let's make every route a BRT route!

Not, design for best vehicle LOS...but make 1 fewer lanes work here.
