New Hampshire tolls: how to maintain

Files: /srv/toll/draft/NH, last built 2026-10-09 21:33 ET · the NH toll page · map test · facts below are read from the files each time this page is built (python3 /home/geo1/system/handbuilt/maintain_pages.py NH)

Procedure for this state

NHDOT's Turnpike System: 7 plazas (Hooksett Main and Ramp, Bedford Main, Hampton Main and Side, Dover, Rochester), 12 classes, from NHDOT's schedule effective January 1, 2022: NH E-ZPass accounts pay the E-ZPass Fare (the 30% / 10% discount, RSA 237:11 V), everyone else — cash, other states' E-ZPass, plate billing at the all-electronic plazas — the posted Cash Fare. Plus the private Mt. Washington Auto Road (per person).

When to check

• January 1, 2027: 2026 chapter 343 changes the tolls (RSA 237:11 V is repealed that day). Fetch NHDOT's new schedule and replace nhdot_toll_rates_2022 (a new source name with the new year), then update the builder's source name and the regression amounts.
• dot.nh.gov refuses geo1: fetch NHDOT documents on b100 with node ~/apitest/fetch_b100.mjs ~/nhfetch <name>=<url>, then rsync -a ~/nhfetch/ geo1@192.168.50.220:/home/geo1/maps/toll/NH/sources/. The statute (nh_rsa_237_11) and NHDOT's plaza layer (nhdot_facilities_toll_plazas) fetch from geo1.
• Mt. Washington Auto Road: its own page each season (mwar_drive_yourself).

Rebuild

python3 nh_state.py parses the schedule PDF (asserts the 7 plaza names and 12 values each) and the class chart (asserts 12 classes). Full chain with NH after an OSM refresh.

Watch out

• Positions are NHDOT's facilities layer (official); booths are the OSM nodes named for each plaza, listed in PLAZA in the builder (asserted within 400 m).
• Merrimack ramp tolls (Exits 10, 11) and the Bedford Road toll are discontinued (schedule header): decisions, not points.
• The Auto Road fee is per person: the amount is the driver alone; the season is not modeled.

The chain every state shares

Hosts: geo1 (192.168.50.220) holds the sources, builders, drafts, map and API; b100 (192.168.50.14) is the test client. All times are Eastern.

1. Refresh a source

1. Fetch into a new dated folder: python3 /home/geo1/system/handbuilt/fetch_list.py NH [name ...] (no names = every line of urls.txt). A new source: add a line to urls.txt first, then fetch it by name.
2. A site that refuses geo1 (HTTP 403) or scripts: fetch it on b100 in headless Chrome with node ~/apitest/fetch_b100.mjs <out> <name>=<url> ..., then rsync -a <out>/ geo1@192.168.50.220:/home/geo1/maps/toll/NH/sources/. Its meta.json records that it came from b100.
3. Compare the new file with the previous dated one (diff, pdftotext -layout for PDFs). Same content: nothing to do. Changed amounts or a new effective date: rebuild (step 2) and update the expected amounts of the affected regression trips from the operator's own figures.

1b. The corpus (NJ, PA, VA start from it; DE is published from it)

python3 /home/geo1/maps/toll/bin/tollup.py NH update fetches the adapter's sources (bin/adapters/nh.py), stores a document only when its content changes, writes one rate file per version under /home/geo1/maps/toll/NH/rates/ and appends every price change to history.csv (every run to runs.log). TOLL_WEB=/home/geo1/maps/toll/corpus python3 /home/geo1/maps/toll/bin/publish.py NH writes the corpus /home/geo1/maps/toll/corpus/NH from it (DE: plain publish.py DE writes /srv/toll/DE). Never hand-edit either. Then rebuild the draft (step 2) so it picks up the new rates.

2. Rebuild

• Amounts or schedules changed, toll points unchanged: cd /home/geo1/system/handbuilt && python3 nh_state.py
• The full chain in one command: bash /home/geo1/system/handbuilt/chain.sh NH (logs in /tmp/nh1.log ... nh6.log; it prints the points, any point on no road and the untied count). The builders written since October 2026 share state_kit.py (sources, booths, terms, rows, write) and own_state.py (keeps a state's untied list to toll nodes inside the state, by the local geocoder; cache osm/node_state.json).
• Toll points added, moved or renamed, or a new OSM extract: the full chain (about 2-4 minutes):
  cd /home/geo1/system/handbuilt; H=$(ls osm/nh_highways_*.geojsonseq); J=$(ls osm/nh_junctions_*.geojsonseq)
python3 nh_state.py && python3 osm_streets.py NH $H $J && python3 nh_state.py && python3 osm_snap.py NH && python3 toll_ways.py NH && python3 nh_state.py
• Read the end of toll_ways.py's output: nodes claimed by two points: {} and points on no road: [] must both be empty.
• A point whose booth is an OSM way (OSM way <id>) needs that way in osm/nh_lane_ways.json (the builder writes it). A point on a road priced entry to exit needs gantry in its location name, or toll_ways.py treats it as a position-only exit marker.
• Rebuilding NY changes osm/ny_not_toll_nodes.json (congestion-zone gantries that are not tolls); every state's untied list leaves those out, so rebuild NJ and PA after NY.

3. Load it into the API and test from b100

1. The API reads the toll pages and tolls.js when it starts. Restart it: cd /home/geo1/maps/api && kill $(cat logs/test.pid); (nohup /home/geo1/maps/node/bin/node server.mjs > logs/server.log 2>&1 & echo $! > logs/test.pid) (it is started by hand, not a service).
2. From b100 only: python3 ~/apitest/run.py ~/apitest/site/cases.json. Every trip must be OK. Add a trip for every rate or rule you change, with the amount taken from the operator's own source.
3. Engine change (tolls.js): edit /home/geo1/maps/web/tolls.js, check with /home/geo1/maps/node/bin/node --check, copy to /srv/maps/tolls.js with sudo install -o www-data -g www-data -m 644, restart the API, run the trips.

4. OpenStreetMap refresh (all states at once)

The builders match toll points to the OSM way ids the router drives, so the extracts here must come from the same us-latest.osm.pbf the router (Valhalla, /home/geo1/maps/valhalla_data) was built from (now 2026-09-27). New OSM data means: rebuild the router tiles, then for each state cut the box, rebuild its OSM inputs and run the full chain, then compare untied_toll_nodes.csv and the estimated positions below. The box for NH and the cutting commands are in the state's procedure above; the toll-node and way index comes from python3 tollnode_ways.py NH.

5. Publish

A rebuild writes the draft (/srv/toll/draft/NH); the published page (/srv/toll/NH) does not change. python3 /home/geo1/maps/toll/bin/promote.py review NH lists the draft for review: the map and the API then read it instead of the published page. Run the regression trips from b100. After approval, python3 /home/geo1/maps/toll/bin/promote.py publish NH copies the draft to /srv/toll/NH (the previous page is kept under /home/geo1/maps/toll/NH/published/<time>/) and takes it off the review list. After a change, update the coverage line for NH in the API page (/api.html, generator /home/geo1/maps/api/doc/api_page.py) and rebuild this page: python3 /home/geo1/system/handbuilt/maintain_pages.py NH.

Sources (10)

Each fetch is kept in its own dated folder under /home/geo1/maps/toll/NH/sources/<name>/; the builder always reads the newest one, so a new fetch takes effect at the next rebuild and the old one stays for comparison.

Facilities (4)

Positions placed by estimate (1): re-check when OpenStreetMap or the operator changes

Decisions by rule

R1: 7, R3: 1, direction: 7, not: 3, per: 1, scheduled: 1 (all in decisions.csv).

Open gaps (0)

None.

Untied OSM toll nodes: 74

Toll booths / gantries mapped in OpenStreetMap on or near this state's roads that no toll point claims; a route through one lists it under unpriced. After an OSM refresh, look at new ones here (untied_toll_nodes.csv): a new gantry on a priced road means a point is missing.

Regression trips for NH (6)

Run from b100 (never on geo1): python3 ~/apitest/run.py ~/apitest/site/cases.json. Every trip must come back OK; a changed amount is either a rate change (update the expected amount from the operator's own source) or a fault.
