救護車端Ambulance side
回傳位置與警笛狀態Share location and siren status
救護車端回傳位置與偵測到的警笛狀態，作為後端判斷提醒的依據。The ambulance app sends location updates and detected siren status for the backend to evaluate.
運作方式How it works
六個方向，
兩個提醒階段。Six directions.
Two alert stages.
CLEARWAY / DIRECTION ZONES
救護車從哪裡接近？Where is the ambulance coming from?
前方FRONT右前FRONT-R右側RIGHT後方REAR左側LEFT左前FRONT-L
目前方向Current direction左前方Front-left
−45°方向語音示例Direction voice example
「請注意！左前方有救護車，請立即準備避讓。」“Ambulance approaching from the front left. Stay alert.”
方向以駕駛行進方向為基準，圖中駕駛固定朝向上方。Directions are relative to the driver’s travel heading. The driver faces upward in this diagram.
ClearWay 將救護車來向分為六個相對方向，依距離與提醒條件提供兩階段音訊，協助駕駛留意周邊路況。ClearWay describes an ambulance’s approach using six relative directions. Two audio stages, based on distance and alert conditions, help drivers stay aware of surrounding traffic.

圖中以 300 公尺／100 公尺示意兩階段提醒；提醒圈、車輛與道路不按真實比例呈現。The diagram uses 300 m and 100 m to illustrate the two alert stages. Rings, vehicles, and roads are not drawn to a common real-world scale.

資訊鏈The information flow
從位置更新，到聽得懂的提醒。From a location update to a useful cue.
測試駕駛完成設定並啟用監測後，App 可在背景接收及播放提醒；實際運作仍受定位、網路與手機設定影響。After setup and monitoring are enabled, the test app can receive and play alerts in the background. Operation depends on location data, connectivity, and phone settings.
02
後端Backend
判斷提醒條件與方向Check alert conditions and direction
後端比對雙方位置、駕駛行進方向與資料狀態，符合提醒條件時，以六個相對方向描述救護車來向。The backend checks both vehicles’ locations, the driver’s travel heading, and data quality. Eligible alerts describe the ambulance using six relative directions.
03
駕駛端Driver side
以兩階段語音提醒Play two-stage audio cues
符合提醒條件時，約 300 公尺提供方向提醒，接近約 100 公尺時提醒準備避讓；若首次符合條件時已在近距離，則直接進入第二階段。When alert conditions are met, a direction cue plays around 300 m, followed by a prepare-to-yield cue around 100 m. If the ambulance is already close when an alert first qualifies, the system goes straight to Stage 2.

ClearWay 不會What ClearWay does not do
替駕駛做道路決策Make road decisions for a driver
- 不提供正式交通指示或要求變換車道It does not issue official traffic directions or lane-change commands
- 不取代警笛、號誌、法規與現場判斷It does not replace sirens, signals, laws, or on-scene judgment
