场景图

导航场景下，支持在当前导航路径上以Icon形式展示出前方交通事件；

路径线上的交通事件

展现的交通事件可以进行交互，点击Icon查看对应的事件详情；

关键参数

事件类型列表见附件1。
使用前需要开启tip交通事件开关：RouteService.control(RouteControlConfigSetTipsInfo, "1")

核心接口

路径的交通事件信息，AutoSDK图层有内聚显示，如果HMI需要主动获取，可以通过调用PathInfo.getTrafficIncident接口取得相关信息。

获取当前路线交通事件信息个数\nshort com.autonavi.gbl.common.path.option.PathInfo.getTrafficIncidentCount(boolean outer)\n\n获取当前路线路径交通事件信息\nTrafficIncident com.autonavi.gbl.common.path.option.PathInfo.getTrafficIncident(short index,boolean outer)

说明：函数详情，请复制函数名称到在线API搜索

关联图层场景见：路线上封路事件图层、路线外封路事件图层
