속도계 알림 구성
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
탐색이 사용 설정되고 이동 모드가 운전으로 설정되면 iOS용 탐색 SDK는 현재 제한 속도를 보여주는 제한 속도 컨트롤을 지도의 왼쪽 하단에 표시합니다. 운전자가 제한 속도를 초과하면 컨트롤이 확장되어 제한 속도 표시 옆에 속도계가 표시되고 속도가 특정 기준점에 도달하면 알림이 트리거됩니다.
기본적으로 Navigation SDK는 운전자가 제한 속도를 5mph (또는 10kph) 초과하면 경미한 속도 알림을 트리거하고 속도계 텍스트의 색상을 빨간색으로 변경합니다. 운전자가 제한 속도를 16km/h (10mph) 초과하면 심각한 속도 알림이 트리거되고 속도계 배경색이 빨간색으로 바뀝니다.
알림을 트리거하는 기준점과 속도계에 표시되는 텍스트 및 배경색을 모두 맞춤설정할 수 있습니다. Navigation SDK를 사용하여 운전자의 속도 정보를 제공할 수도 있습니다. 예를 들어 차량 공유 서비스 운영자가 운전자가 제한 속도를 준수하고 안전을 개선하도록 장려할 수 있도록 속도 정보를 제공할 수 있습니다.
속도 알림 기준 맞춤설정
현재 속도의 제한 속도에 대한 백분율로 경미한 속도 알림과 심각한 속도 알림의 속도 알림 기준점을 맞춤설정할 수 있습니다. 지도가 알림을 표시하기 전에 임곗값을 초과하는 기간을 지정할 수도 있습니다.
다음 코드 예시에서는 경미한 속도 알림의 기준을 제한 속도보다 5% 높게, 심각한 속도 알림의 기준을 제한 속도보다 10% 높게 설정합니다. 경고 임곗값이 5초 동안 초과된 후 지도가 경고를 표시하도록 지정합니다.

애플리케이션에서 운전자 속도에 관한 정보를 공유해야 하는 경우 Navigation SDK를 사용하여 운전자 속도 정보를 제공할 수도 있습니다.
이는 운전자의 과속을 모니터링하여 안전을 개선하려는 운영자가 있을 수 있는 차량 공유 애플리케이션에 유용할 수 있습니다.
예를 들어 다음 예에서는 속도가 제한 속도를 지정된 비율만큼 초과하는 경우 속도 정보를 공유합니다.

If a driver exceeds the speed limit, the\ncontrol expands to display a speedometer next to the speed limit display and\ntriggers alerts when the speed reaches a certain threshold.\n\nBy default, the Navigation SDK triggers a minor speed alert when the driver\nexceeds the speed limit by 5 mph (or 10 kph), and changes the color of the\nspeedometer text to red. It triggers a major speed alert when the driver exceeds\nthe speed limit by 10 mph (or 20 kph), and changes the speedometer background\ncolor to red. \n\nYou can customize both the threshold for triggering the alerts and the text and\nbackground colors the speedometer displays. You can also use the Navigation SDK\nto make the driver's speed information available. For example, you could make\nspeed information available to rideshare operators to help them encourage their\ndrivers to adhere to the speed limit and improve safety.\n\nCustomizing thresholds for speed alerts\n---------------------------------------\n\nYou can customize the speed alert threshold for both minor and major speed\nalerts as a percentage over the speed limit of the current speed. You can also\nspecify how long the threshold is exceeded before the map displays the alert.\n\nThe following code example sets the threshold for a minor speed alert to five\npercent over the speed limit, and the threshold for a major speed alert to 10\npercent over the speed limit.
