Bus schedule method, applied to the Hlučínsko lines at sad B. Němcové (25 Oct 2026)

The owner asked for the lines 281, 282, 290 and 292 to be checked by hand, step by step against ../bus-schedule-method.md (v3), as the Hranečník lines were (../ostrava-bus/method-check-odis-2026-10-20.md): "Yes, I want you to check - that's the point of you doing it, so you'll not produce incorrect results." Their published rows (21 Oct, sheet v6) were the builder's automatic fits (at: 'auto'), and every one of them failed Step 4. Final state: sheet v8.

Data: the sheet's own JDF trips for Tue 20 Oct 2026 (data/derived/trips.json), the whole-day reading (data/derived/reading/.txt) and the ODIS live-map plate chains (chains.json, 13:00–19:30).
Step 4 test, per direction: in the model window the slots must equal the real departures ±1, and at least 80 % of the slots need a real departure within 3 min. Then most exact over the day, then the simplest.
Typed values are (real − 61) mod every: every terminus is a loop.

What the plates show: outstation lines

The buses of these lines sleep at the far ends: the Hať garage, Třebom, Strahovice, Chuchelná and Píšť. The first morning trips start there (290 Hať 4:02–5:54, 281 Třebom 3:51, 292 Strahovice 3:46 / 4:48 / 6:03), and in the afternoon the buses go home on the peak trips out of Ostrava. Between 14:00 and 17:00, 19 departures leave sad B. Němcové on the four lines and 12 arrive. The deficit cannot be paired across the four lines (Step 5b): every one of them sends more out than it brings back, and the live map shows the extra buses ending their day at the far end or running back empty for another line (24-1105: out on 290 at 14:16, then back empty for 281 at 15:45).

So each line is timed both ways at its inbound rate, and the extra peak departures out of Ostrava (buses going home) are off the pattern. That breaks Step 4's "slots = real departures ±1" out of Ostrava for 281 and 292, by the owner's choice:

v7 (withdrawn) put the extra departures on B lines with an empty return (281B, 290B, 292B, the 387 / 543B precedent): 5 more buses, shuttling back empty all day in the game.
Owner, 25 Oct 2026: "Unless those empty runs add something really needed and specific, don't add them just for frequency." The B lines ran the same stops as their core lines (coverage stays 0 uncovered without them), so they were dropped in v8.

Step 5b does pair two trips at Píšť. 282 out at 14:53 comes back as 292 at 15:53 (via Vřesina). 292 out of Hlučín at 14:30 comes back as 282 at 15:55 (via Bohuslavice). That is a 1:1 swap of paths, so it changes no count, and each line stays balanced on its own path.

Summary

Line	Published (v6)	Step 4	Now (v8)	Buses
281	every 60, Třebom :16 / Ostrava :18	Třebom :16 is 15–20 min off the afternoon (15:01, 15:56)	every 60, Třebom :58 (Kobeřice :13) / Ostrava :18	3 → 3
282	every 180, Píšť 15:55 / Ostrava 13:54 slot, model hour 13:00–15:00	the 13:54 slot has no trip	every 120, Píšť :55 / Ostrava :53, model hour 16:00	1 → 1
290	every 40, Hať :07 / Ostrava :19	3 slots for 5 departures out; 15:39 and 15:27 slots empty	every 120, four slots each way, exact	3 → 4
292	every 90, Ostrava 14:04 / Chuchelná 14:21	14:04 slot empty; 15:51 slot empty	every 80, Ostrava 14:33 / 15:53, back timed at Hlučín :59	2 → 2
Total				9 → 10

The sheet needs 126 buses (was 125). The published buses stay where they are still seen on their line (config.keep_roster = data/published/roster_v6.json): 281 takes 24-0002 in place of 24-0004 (whose 13:16 trip is now off the pattern), and 290 adds 24-1111. The seven rows these lines had on the To check list are gone from the "slot without a real departure" kind. The owner chose 290's four slots (4 buses) over every 40 (3 buses): "290 uses more buses".

290 Hať – Hlučín – Ostrava, Přívoz

(a) Core points: Hať, točna; Hlučín, autobusové nádraží; Ostrava, Přívoz, sad B. Němcové. Model hours 14:40–16:40.
(b) Afternoon: out of Ostrava (at sad B. Němcové) 13:59, 14:19, 14:44, 14:59, 15:24, 15:49, 16:19, 16:54, 17:29; from Hať 13:49, 14:47, 15:31, 16:07, 16:37, 17:37 (to Hlučín), 18:08.

(c) Step 4 out of Ostrava (window 5 real):

Candidate	Window slots	Within 3 min
every 40 :19 (published)	3	2 of 3, FAIL
every 30 :19	4	2 of 4, FAIL
every 60 :19 :44	4	2 of 4, FAIL
every 60 :24 :49	4	2 of 4, FAIL
every 120, 14:44 14:59 15:24 15:49	4	4 of 4, exact

From Hať (window 4 real): every 40 :07 2 of 3 FAIL; every 60 :07 :37 2 of 4 FAIL; every 60 :07 :47 2 of 4 FAIL; every 120, 14:47 15:31 16:07 16:37: 4 of 4, exact.

(d) Simutrans line 290: every 120. Hať Offset 30, Also at 66, 96, 106 (real 15:31, 16:07, 16:37, 14:47); Ostrava Offset 23, Also at 48, 103, 118 (real 15:24, 15:49, 14:44, 14:59). The plates pair 14:44 → 15:31 (24-1104), 15:24 → 16:07 (24-1006) and 15:49 → 16:37 (24-1111). The fifth departure is left off: 16:19 (24-1115 goes home to the garage), not 14:59; with 16:19 in the pattern instead, one bus waits 108 min at Hať and the line needs 5 buses, not 4.
(e) Knots: Hlučín within 1 min of the real passing times (3 for 14:44); the model reaches sad B. Němcové 2 min after the real arrivals.
(f) Off the pattern 12–20 h: out 12:09, 13:19 (5), 13:59 (10), 14:19, 16:19 (home runs), 16:54 (5), 17:29 (5); from Hať 12:29 (8), 13:49 (18), 19:58 (9); the Hlučín – Hať trips (17:37, 18:40) and the 13:39 to Hať, garáž ČSAD.
(g) Need: 4 (waits Hať 33, 18, 7, 28; Ostrava 32, 11, 6, 21).

281 Třebom – Kobeřice – Hlučín – Ostrava, Přívoz

(a) Core points: Třebom, náměstí; Kobeřice, autobusová stanice (the knot where the Třebom, Strahovice and Kobeřice trips split); Hlučín; sad B. Němcové. Model hours 14:10–16:10.
(b) Afternoon: out of Ostrava 13:43, 14:18, 14:48, 15:18, 15:48 (Strahovice), 16:13 (Strahovice), 17:18; towards Ostrava, read at Kobeřice: 13:31, 14:11 (starts there), 15:16, 16:11, 17:38 (Třebom 13:16, 15:01, 15:56, 17:16). Hlučín – Bolatice shuttles 13:40, 14:40, 15:10, and Bolatice 15:23 → Ostrava.
(c) Step 4: back at Kobeřice: every 60 :11 1 of 2 FAIL; :16 1 of 2 FAIL; :13 2 of 2 within 3 min (14:11, 15:16; also 16:11). The published Třebom :16 is 15–20 min off every afternoon trip. Out of Ostrava the timetable is exactly every 30 (:18 / :48); the line runs at the inbound rate, hourly at :18 (14:18, 15:18 exact).
(d) Simutrans line 281: every 60, Třebom Offset 57 (real :58, so the bus passes Kobeřice at :13), Ostrava Offset 17 (real :18).
(e) Knots: out exact at Kobeřice and Třebom; back Hlučín 15:48 / 16:48 against 15:46 / 16:41 (the model's median running time to Hlučín includes the longer Bolatice path).
(f) Off the pattern: out the :48 departures (12:48, 13:43, 14:48, 15:48; their buses go home), 16:13, 18:43; back Třebom 13:16, 17:16, 19:37; the Hlučín – Bolatice shuttles (Bolatice stops are on 252, 254 and 284).
(g) Need: 3 (waits Třebom 35, Ostrava 22).

282 Píšť – Bohuslavice – Hlučín – Ostrava, Přívoz

(a) Core points: Píšť, kostel; Hlučín; sad B. Němcové.
(b) Afternoon: Píšť leaves exactly every 2 h at :55: 13:55 (to Dolní Benešov), 15:55 (to Ostrava), 17:55, 19:55, 21:55 (to Hlučín). Ostrava → Píšť 14:18, 14:53, 16:54; Hlučín → Píšť 16:10, 18:10, 19:15 (with the Ostrava trips, hourly at :10 at Hlučín from 15:10 to 18:10). Hlučín – Závada shuttles 13:05 / 13:28, 14:05 / 14:28.
Model hour: the line's busiest stretch, 13:00–15:00, is the Závada shuttles, whose stops are all on 282. Its pattern runs later, so the anchor is set by hand to 16:00 (window 15:30–17:30), as was done for 451 and 533.
(c) Step 4: published every 180 (Ostrava 13:54 slot): 0 of 1 FAIL. Every 120: Píšť :55 exact 4 times over the day; Ostrava :53 (14:53, 16:54).
(d) Simutrans line 282: every 120, Píšť Offset 54 (real 13:55, 15:55, 17:55; read to Hlučín, as the later trips end there), Ostrava Offset 112 (real 14:53, 16:53).
(e) Knots: Hlučín within 1–3 min.
(f) Off the pattern: Ostrava 14:18; Hlučín → Píšť 16:10, 18:10 (their stops are on 282); the Závada shuttles.
(g) Need: 1 (waits Píšť 16, Ostrava 13). Bohuslavice has no other line.

292 Ostrava, Přívoz – Hlučín – Vřesina – Píšť – Chuchelná / Strahovice

(a) Core points: sad B. Němcové; Hlučín (the knot for the way back: the trips start at Píšť, Chuchelná or Strahovice); Píšť, Mýto (where the Chuchelná and Strahovice paths split); Chuchelná, železniční stanice. Model hours 14:00–16:00.
(b) Afternoon: out of Ostrava 13:29 (Píšť only), 13:53, 14:33, 14:58, 15:33, 15:53, 17:04, 18:49; towards Ostrava, at Hlučín 13:39 (Píšť), 15:02 (Chuchelná), 16:16 (Píšť), 17:26 (Strahovice), 19:34 (Strahovice).
(c) Step 4: back at Hlučín: every 80 :59 (13:39, 14:59, 16:19; within 3, 17:26 is 13 off) and every 72 (15:02, 16:14, 17:26; 13:39 11 off) both pass in the window; 72 hits one more on the minute, but only 80 lets the line leave Ostrava on two exact departures (14:33, 15:53), so 80. The published every 90 (Ostrava 14:04) 1 of 2 FAIL, Chuchelná 15:51 slot empty. Out of Ostrava the timetable is every 30 (:33 and :53–:58); the line runs at the inbound rate.
(d) Simutrans line 292: every 80, Ostrava Offset 12 (real 14:33, 15:53), Chuchelná Offset 77 (real 14:18, 15:38; the bus passes Hlučín at 14:59 / 16:19). Out trips are counted to Píšť, Mýto, so the Strahovice runs (15:53) count.
(e) Knots: out Hlučín 14:49 / 16:09 (real 14:50 / 16:10). The sheet's knot check shows 18–19 min for the 15:53 slot and 77 at sad B. Němcové for the 15:38 slot. Those compare only with trips that run the whole Chuchelná path; the 15:53 runs to Strahovice by the other path and the 15:38 slot stands for the Píšť 15:53 trip, both within 1–3 min at Hlučín.
(f) Off the pattern: out 12:34, 13:29 (Píšť only), 13:53, 14:58 and 15:33 (their buses go home to Chuchelná / Strahovice), 17:04, 18:49; back at Hlučín 17:26 (13), 19:34; the Hlučín – Vřesina / Píšť Mýto shorts and the Chuchelná – Strahovice and Bělá shuttles (stops on 292 and 282).
(g) Need: 2 (waits Ostrava 39, Chuchelná 9).

Shared stop: sad B. Němcové (Step 5)

Model departures 14:00–16:20 of the four lines: 14:18 (281), 14:33 (292), 14:44 (290), 14:53 (282), 14:59 (290), 15:18 (281), 15:24 (290), 15:49 (290), 15:53 (292), 16:18 (281). Every one but 281's 16:18 (real 16:13, a Strahovice trip) is a real departure, and no two leave within 3 min. The DPO lines at the same stop (34, 56, 67, 68 …) were not changed.

Buses and other sheets

281: 24-1103, 24-1010, 24-0002 (in place of 24-0004). 282: 24-1001. 290: 24-1104, 24-1102, 24-1009, 24-1111 (added). 292: 24-1116, 24-1007. All seen on these lines on 20 Oct; every other line of the sheet keeps its buses.
No bus is on two sheets: checked against the HKO, TFJ, Novojičínsko and Bruntálsko rosters, the Ostrava Hranečník cards and the Havířov/Karviná/Orlová town sheet (the roster step excludes the 304 plates of the earlier sheets).
keep_roster is new in the shared odis-regional-hko/scripts/04_roster.py (step 6, opt-in per sheet): published buses stay on their Simutrans line wherever they are still evidence for it, so a rebuild moves the fewest buses.
Pooling (not applied): the real buses swap between these lines at sad B. Němcové all afternoon. One pool for the corridor would need fewer buses than 10 separate ones. That is the owner's choice.

The rest of the sheet

Owner, after the four lines above: "verify all sheets with this level of detail". The work list was this sheet's part of ../audit/audit-regional-2026-10-25.md: 58 failing legs on 34 Simutrans lines (55 EMPTY, 3 FEWER). 281, 282, 290 and 292 stay as above (their FEWER rows are the owner-approved outstation case). Every other failing line was read over the whole day (data/derived/reading/.txt, plates from the 20 Oct live map) and set by hand in authoring/opa_spec.py; the cards are in authoring/opa_notes.py, the new owner checks in authoring/opa_config.py. Typed values are (real − 61) mod every (every terminus is a loop); each real time below is worked out from its own value. Model windows are each line's anchor −30 to +90 (05_schedule), except where set by hand (075, 555, 285).

How the candidates were chosen. For each line both directions were searched together: every interval of the method's list (10 … 480) and 1–8 slots per direction, the slots placed on the window's real departures, both directions on the same interval with the same number of slots (Step 7), and the need from the slot matching of 05_schedule. Then:

Gate: Step 4 in each direction (window slots = real departures ±1; at least 80 % of the slots with a real departure within 3 min). Where a direction has two or more departures in the window the interval is at most 120, so the pattern repeats at least as often as the window it stands for (every 160 with three slots also "fits" a 2-hour window, at three quarters of the real rate).
Order among passing rows: most departures exactly on the minute over the day (5–23), then within 1 min, then fewest slots, then fewest buses. On one-departure-per-window lines these counts are 1–3 and mostly tie; there the real 13:00–18:00 headway decides, never "the longer interval" (a 2-hourly line is not pulled to 240 or 480).
More buses than a passing cheaper row (the cheaper one has one slot fewer than the window's departures, or is the earlier approximate row): the exact row goes on the sheet, the cheaper one on the owner checks with its saving (the 290 precedent: "290 uses more buses").
Window imbalance (more out than back): the outstation rule of 25 Oct, inbound rate, the departures that fall off chosen by the plates and the waits.
Hourly line, narrow window (mistakes table: 409 and 411): an hourly row with one stray trip stays hourly, approximate, rather than be halved by a passing every 120.
No pattern passes both ways: the simplest even row at the real rate, approximate, on the To check list.

Rebuilt with 05_schedule.py --base odis-regional-opavsko: coverage 633 afternoon stops, 0 uncovered. Re-audit (step4_regional.py odis-regional-opavsko): 141 timed legs, 128 ok (was 85 of 143), 10 EMPTY, 3 FEWER; the failing ones are the approximate rows and owner checks listed at the end, and the three FEWER rows are 281, 292 and 236 (outstation).

(c) Published hourly: Opava 2 / 2 filled 0 (14:25 is 5 min off, 15:25 empty), FAIL; Kobeřice passes. No hourly phase passes out of Opava. Every 120 with two slots each way: 2 / 2 filled both, 2 + 8 exact, need 3. Every 120 with one slot (14:50 / 13:45) passes too but halves the line.
(d) 252 every 120. Opava Offset 79 (14:20), Also at 109 (14:50); Kobeřice Offset 44 (13:45), Also at 104 (14:45) (the same as every 60 at :45, Offset 44).
(e) Kravaře and Kobeřice 6–7 off (the model takes the commonest path's running time); back exact at Opava for 14:45.
(f) Off: Opava 12:45, 15:45, 16:25, 17:25, 18:25; Kobeřice 12:15.
(g) Need 2 → 3 (waits Opava 28, 58; Kobeřice 98, 8). Owner check: the earlier hourly row, 2 buses, approximate.

(c) Published every 90 (14:13 / 14:10): 2 / 2 filled 1 and 2 / 2 filled 0, FAIL. Every 120 with two slots each way: all filled, 3 + 2 exact, need 3. Every 80 with one slot (14:43 / 14:45): passes, 2 + 2 exact, need 2.
(d) 262 every 120. Opava Offset 74 (14:15), Also at 102 (14:43); Bílovec Offset 44 (15:45), Also at 104 (14:45) (the same as every 60 at :45, Offset 44). Out via Slatina as before.

Plates: 22-0101 out 15:31, back 16:12; 22-1008 out 16:59 ends at Pustá Polom; the morning trips start there (4:38, 6:00, 7:00): the buses sleep at Pustá Polom.
(c) Published every 120 (16:38 / 17:13): both 0 of 1, FAIL. Inbound rate, every 120: Opava 15:31 (or 16:59) with Těškovice 15:58: both pass, 1 / 2 and 1 / 1 filled, 1 + 1 exact, need 2. 16:59 is the bus going home, so 15:31 stays.
(d) 263 every 120. Opava Offset 30 (15:31); Těškovice Offset 57 (15:58), so the bus passes Pustá Polom at 16:12.
(e) Pustá Polom 16:12 exact. The card's knot check compares with whole Opava – Těškovice trips (few in the afternoon: 18:38 out, 17:40 back), so it shows 94–190 there.
(f) Off: Opava 16:59, 18:38, 19:46; Těškovice 17:40; the Budišovice and Hlubočec trips.

285 Ostrava, Poruba, Dílny DP – Dobroslavice – Štítina

(b) The Štítina trips run 13:03–15:50 only: Poruba 13:09, 14:09, 15:09; Štítina 13:03, 13:48, 14:53, 15:50, by two buses alternating (24-1112: 13:09 / 13:48, 15:09 / 15:50; 22-0005: 13:03, 14:09 / 14:53). The 16:00 model hour of the line came from the Dobroslavice short trips.
(c) Published every 90 (16:11 / 16:48) in 15:30–17:30, where the trunk has no departures: 1 / 0 and 1 / 1, 0 filled, FAIL. In 13:00–15:00: every 120, Poruba 13:09 / 14:09 and Štítina 13:48 / 14:53: 2 / 2 and 2 / 3 filled, 3 + 2 exact, need 2; hourly :09 / :50 passes with 3 + 1, need 2.
285 Dobroslavice (Poruba – Dobroslavice shorts) counted the Štítina trips past Dobroslavice (:09 → :21) as its own. With them taken out, its afternoon is out 15:49 (to Mokré Lazce), 16:49, 17:19 (to Háj) and back 17:01: no pattern passes, and all its stops are on 285 (Step 8: a variant whose stops another line serves is listed, not a line). Dropped; the shorts (hourly :09 / :41 at midday) are listed on the 285 card.
(d) 285 every 120. Poruba Offset 8 (13:09), Also at 68 (14:09) (the same as every 60 at :09); Štítina Offset 47 (13:48), Also at 112 (14:53).

(c) Published every 90 (16:55 / 16:11): both 0 of 1, FAIL. Every 120 (17:05 / 16:22) passes, 2 + 1 exact, but one of the two is 293 ŽD's 13:05: every 120 at odd hours :05 leaves Hlučín at 13:05 with 293 ŽD (check 6). Every 96 (17:05 / 16:22): 1 + 1 exact, need 1, no shared minute, and the real headway is about 95.
(d) 293 every 96. Hlučín Offset 4 (17:05); Bohumín Offset 57 (16:22).
(e) Exact both ways.
(f) Off: Hlučín 15:10; Bohumín 15:02, 18:17.

555 Bohumín, Starý Bohumín – Ostrava, Náměstí Republiky

(a) Starý Bohumín, nám. Svobody; Ostrava, Náměstí Republiky. Model hour 16:00 by hand (was 14:00).
(b) From 15:00 Bohumín :01 / :28 (15:01 – 17:28) and Ostrava :20 / :50 (14:50 – 17:50); before that 13:08, 13:41, 14:28 and 13:20, 14:00, 14:30. Two Nový Bohumín AS shorts (13:35, 14:03, stops on the line) made 13:30–15:30 the busiest; without them 15:00–17:00 ties it, so the v4 rule (as 282) sets 16:00.
(c) Published every 30 at 14:00: 4 / 4 filled 3 and 2, FAIL. At 14:00 the passing rows are every 120 with three or four slots (exact there, but :28 / :01 / :41 every 2 h, wrong from 15:30 on). At 16:00: hourly with :01 / :28 and :20 / :50, 4 / 4 filled 4 both ways, 7 + 10 exact, need 4; every 30 (:28 / :20) passes with 4 + 10.
(d) 555 every 60. Bohumín Offset 0 (:01), Also at 27 (:28); Ostrava Offset 19 (:20), Also at 49 (:50) (that entry is every 30 at :20; the sheet prints the line's every 60).
(e) Within 2 at both ends.
(f) Off: Bohumín 13:08, 13:41, 18:15, 19:05; Ostrava 12:30, 14:00, 14:30, 19:10.
(g) Need 4 (waits Bohumín 26, 29; Ostrava 10, 7).

Failing legs left approximate

217 (both ways, hand-set hourly :04 / :25): the window's Koupaliště slots and Slavkov 15:25 have no trip because the early-afternoon trips run Divadlo – Slavkov; that is the open owner check. Not changed.
920 (four legs): the :17 pattern from Svinov holds 10:17–15:17; in the 16:00 window the Šumperk trip leaves at 16:47 (not 16:17), there is no 17:17 Rýmařov trip, and the Šumperk 16:35 and Rýmařov 15:32 slots have no trip. This is the open 920 owner check (the split); no single minute is wrong within the chosen design. Not changed.
248 (Heřmanice → Opava): hourly with gaps, kept hourly (rule 5); owner check offers every 120 with 1 bus.
251 (Opava → Chlebičov): hourly, 7 of 9 on the minute, the 15:35 runs at 15:05; kept hourly (rule 5). Every 120 (16:35 / 17:05) would pass with the same bus.
254 (both ways): out 14:38, 15:18, 16:28 and back 14:30 in the window (16:30 sits on its end), so no pattern passes both ways; the published every 90 is already the best phase (Opava 16:28, Chuchelná 14:30 / 17:30 exact, 16:28 → 17:30 is one bus, 22-1040). Kept, approximate; 14:58 and 16:00 slots have no trip. Not moved to the outstation every 120 (it would need 1 bus), because the 16:28 bus does come back at 17:30.
236 (Vítkov → Budišov) is FEWER by design (outstation), as 281 and 292.

For the orchestrator

Fold: four entries are evenly spaced on their line's interval and are every 30 / every 60 in the fork's terms: 555 Ostrava (every 60 at :20 / :50 = every 30, Offset 19), 285 Poruba (every 120 at 13:09 / 14:09 = every 60, Offset 8), 252 Kobeřice and 262 Bílovec (every 120 at 13:45 / 14:45 and 14:45 / 15:45 = every 60, Offset 44). 06_render prints one every per line and does not fold; fork-schedule.md says to type the folded form.
Owner checks: the sheet now has seven, and 06_render writes their number as a word from a list that ends at "seven": an eighth would fail the render.
Roster: 285 Dobroslavice no longer exists (its bus is free); 215, 233, 241, 252, 262, 264 and 285 need more buses (keep_roster keeps the published ones where they are still seen). 04_roster, 06_render and publishing were not run.
Pooling (not applied): the Opava – Vítkov lines 240 / 241 / 242 share one pool at both ends (241 alone needs 4 buses for four trips run by four pool buses); 252 / 255 hand buses over at Kobeřice.
