Add Latvia (NAP/CC0), Portugal (Porto/ODbL) and Ukraine (data.gov.ua/…

[travelcamnet]

Adds three open, free-to-reuse traffic data sources to the Europe list that aren't currently included.

Latvia — the Latvian National Access Point (transportdata.gov.lv), 55 Datex-II v3 datasets (incidents, closures, roadworks, restrictions, weather), all CC0. Free registration + per-dataset subscription.

Portugal — the national NAP (anonymous JSON catalog); road-traffic Datex-II is municipal, with Porto's unplanned-road-conditions feed (Datex-II v3, ODbL) as the cleanest native road-events source.

Ukraine — no national NAP/Datex, but data.gov.ua (CC BY 4.0) carries accident black-spots, Kyiv road closures/repairs, and historical border-queue data.

For transparency: I found these while building napspan, an EU traffic-data aggregator, and integrate each of them — figured the open ones missing from this list were worth contributing back. All entries follow the existing portal + format + license style; licenses verified (CC0 / ODbL / CC BY 4.0).

Can you specify the more specific links to these data sets? It seems you included just the links to their generic open data platforms.

Sure — here are the concrete dataset links. The portal roots were deliberate for Latvia (each feed is a separate subscription card) and Ukraine (it's a dataset-by-dataset portal, not one feed), but the specific
cards/datasets are below, and I'm happy to fold these into the README lines.

🇱Latvia — transportdata.gov.lv. 55 CC0 DATEX-II v3 datasets, each its own subscription card. The road-event headliners:

• Accidents & incidents — https://transportdata.gov.lv/card/e8659cdd-9372-41fd-8b28-e7c742895bdd

• Road closures — https://transportdata.gov.lv/card/75611a36-e66b-40cf-af2c-69db48c278cf

• Road works — https://transportdata.gov.lv/card/35fa5c41-90ce-4b74-a4a3-08216d470134

• Weight & dimension restrictions — https://transportdata.gov.lv/card/d5337096-f00f-4d51-93f2-32f643c65f9e

• Poor road conditions / weather — https://transportdata.gov.lv/card/fc967039-7c4f-4958-b61e-0c75db56e2dd

• The full card catalogue is browsable from https://transportdata.gov.lv/en (filter by publisher "Latvijas Valsts ceļi"); all pull via the same POST /api/v1/get/file/download-file endpoint once you subscribe to a card.

🇵Portugal — Porto "Condicionamentos não programados" (unplanned road conditions), DATEX-II v3, ODbL:

• Dataset page — https://opendata.porto.digital/dataset/cb350387-ceb0-4aac-8a27-adfcf512a456
• Direct DATEX-II XML — https://opendata.porto.digital/dataset/cb350387-ceb0-4aac-8a27-adfcf512a456/resource/6758556c-bddf-4c87-a98c-9af08d6932c3/download/condicionamentos_nao_programados.xml

🇺Ukraine — the specific CC BY 4.0 datasets (it's dataset-by-dataset, no single feed):

• Accident black-spots / hazardous road sections (WGS84 coords) — https://data.gov.ua/dataset/7576fcf4-d79f-49af-ab1e-be0671116a57
• Border truck/bus queue — historical (monthly CSV) — https://data.gov.ua/dataset/a8909a08-4da6-49c5-9238-6ab227059c51
• Border-crossing points directory — https://data.gov.ua/dataset/d3e67d5f-f9b9-426f-8140-718a68d88791
• Kyiv road closures & repairs (Kyiv open-data ArcGIS) — https://gisserver.kyivcity.gov.ua/mayno/rest/services/KYIV_API/Перекриття/MapServer/0
• Kyiv official parking inventory — https://gisserver.kyivcity.gov.ua/mayno/rest/services/parking/Parking_ADM_INSP/MapServer/0

Want me to update the three README lines to embed these specific links directly?

[karussell]

Yes, please update the PR to include the more specific links (we only need road closures and accidents, i.e. only those that lead to blocked roads or have a specific km/h associated)
