OmniRadar：出門前，把路況與天氣放在同一個視野OmniRadar: road and weather conditions in one view before you go

專案是什麼

OmniRadar（山海路全方位雷達）是給台灣騎士與戶外玩家的出發前儀表板。跑山路線的沿線攝影機、海邊的浪況與潮汐、高山的氣溫與日出時間，連同即時氣象數據，被整理在同一個頁面。它是民間的資料整合服務，不是導航軟體，也不是官方的道路安全評估。

為什麼做這個

出發前常常要開好幾個分頁：到公路局找沿線監視器，到氣象署查氣溫與降雨，再開地圖看路線；去海邊還要另外查潮汐與風浪。資訊分散在不同網站，決定要不要出門總是拿不定主意。OmniRadar 想把這些決定性的資訊放在同一個畫面，減少出發前來回切換的時間。

可以做什麼

• 沿線影像：選一條路線，沿線攝影機依里程排列，不必在地圖上逐一尋找。
• 氣象數據：影像旁附上最近測站的氣溫、雨量與風速；海邊與高山專區另有潮汐、浪高、紫外線與日出倒數。
• 燈號提示：用「適合」「注意」「不建議」標出需要留意的路段，並寫出原因，而不是只給一個顏色。
• 車友回報：登入的車友可以回報落石、濕滑、事故等狀況，由其他車友確認，到期自動消失。
• 三個專區：跑山、海洋與高山，各有適合該情境的資料與判斷。

怎麼使用

以出發前確認一條山路為例：

1. 選擇要去的路線，查看沿線攝影機的畫面與畫面標示的更新時間。
2. 對照旁邊的氣溫、雨量與風速，留意最近一兩個小時的累積雨量。
3. 看燈號與它寫出的原因，確認是哪一段、為什麼被標為「注意」。
4. 另外到公路局確認即時的封路與管制公告。
5. 最後以現場狀況和自己的判斷決定是否出發。

設計上的取捨

• 分清楚資料的層級：官方觀測、本站推估與車友回報在頁面上分開標示，讀者可以知道每一個數字是誰給的。
• 推估只往保守的方向修正：例如路面乾濕的推估只會朝「比較濕」修正，不會因為雨停了就直接說「已乾」。
• 資料太舊就不判斷：每個頁面標出觀測或更新時間，資料超過三小時就不做判斷。
• 不顯示未經確認的「正常通行」：站內沒有自動介接即時封路，因此不會顯示正常通行的訊息，請以公路局公告為準。

技術與資料來源

• 即時影像：交通部公路局、新北市政府交通局，以及國家公園、風景區與林業署的直播；影像由你的瀏覽器直接向來源載入，本站不儲存也不轉播。
• 氣象與天文：中央氣象署的氣溫、濕度、風速風向、雨量、紫外線、資料浮標的浪高與海溫、潮汐預報與日出日落。
• 道路管制：交通部公路局公告，本站人工整理固定的限制並註明查證日期。
• 地圖與路線：OpenStreetMap 貢獻者資料與地形高度資料，爬升與下降為估計值。

限制與注意事項

• 這不是導航軟體，不提供路線導引。
• 燈號與推估只是依資料計算的參考，不代表官方發布的封路、災情或放行公告。
• 測站不在路面上，攝影機與測站都可能斷線或延遲，山區的溫度與降雨可能差異很大。
• 請勿在騎乘或駕駛途中操作網站，需要查看時請先停車。
• 本站為民間資料整合服務，與任何政府機關無隸屬關係。

What it is

OmniRadar is a pre-trip dashboard for riders and outdoor people in Taiwan. Roadside cameras along mountain roads, surf and tides at the coast, and temperature and sunrise on high mountains are gathered on one page together with live weather data. It is an independent data-aggregation service. It is not a navigation app and not an official road-safety assessment.

Why we built it

Before a trip you often open several tabs: the highway bureau for roadside cameras, the weather agency for temperature and rain, a map for the route, and separate sites for tides and waves if you head to the coast. Information is scattered and the go or no-go decision is hard to make. OmniRadar puts the deciding information in one view so you spend less time switching between sites.

What you can do with it

• Roadside images: choose a route and the cameras along it are listed by distance, so you do not have to find them one by one on a map.
• Weather data: temperature, rain and wind from the nearest station next to the images; the coast and mountain zones add tides, wave height, UV and a sunrise countdown.
• Signal lights: "suitable", "caution" and "not recommended" mark sections to watch, with the reason written out instead of a colour alone.
• Rider reports: signed-in riders can report rockfall, slippery roads and accidents, which other riders confirm and which expire automatically.
• Three zones: mountain roads, ocean and alpine, each with data and judgements suited to the situation.

How to use it

Checking a mountain road before leaving, for example:

1. Choose your route and look at the cameras along it, along with the update time shown on each image.
2. Compare the temperature, rain and wind beside them, and pay attention to rain accumulated over the last hour or two.
3. Read the signal light and the reason it gives, to see which section is marked "caution" and why.
4. Check the highway bureau separately for live road closures and restrictions.
5. Decide whether to go based on the conditions on site and your own judgement.

Design decisions

• Keep the layers of data apart: official observations, site estimates and rider reports are labelled separately, so you can see who produced each number.
• Estimates only move toward caution: for example, the road wet/dry estimate only gets corrected toward "wetter", and does not claim "dry" just because the rain stopped.
• No judgement from stale data: each page shows its observation or update time, and data older than three hours is not used for a judgement.
• No unconfirmed "normal traffic": live closures are not connected automatically, so the site never shows a normal-traffic message. Rely on the highway bureau's announcements.

Technology and data sources

• Live images: the Directorate General of Highways, the New Taipei City Transportation Department, and live streams from national parks, scenic areas and the Forestry Agency. Images are loaded by your browser directly from the source and are not stored or relayed by the site.
• Weather and astronomy: the Central Weather Administration's temperature, humidity, wind, rainfall, UV, buoy wave height and sea temperature, tide forecasts, and sunrise and sunset.
• Road restrictions: announcements from the Directorate General of Highways. Fixed restrictions are compiled by hand with the verification date noted.
• Maps and routes: OpenStreetMap contributors and terrain elevation data. Climb and descent are estimates.

The full sources, update frequencies and licences are on OmniRadar's data sources page.

Limitations

• It is not a navigation app and gives no route guidance.
• Signal lights and estimates are reference values computed from data. They do not represent official closure, disaster or reopening announcements.
• Stations are not on the road surface, cameras and stations can go offline or be delayed, and temperature and rain in the mountains can differ a lot.
• Do not use the site while riding or driving. Stop first when you need to check.
• It is an independent service and is not affiliated with any government agency.

Other projects

• KESI Tools: You just want to convert an image or merge two PDFs, but you are asked to install software, sign up, or upload files to a server you know nothing about.
• GearLab: You bought a high-refresh monitor or a high-polling-rate mouse, but have no easy way to tell whether it really runs to spec on your own PC.
• AfterHero: Receipts and warranty cards are scattered across drawers and inboxes, and you only find out a warranty has expired when something breaks.
