Alerts service extracts information from the road graph and helps track it through eHorizon. AlertServiceOptions control how Navigation SDK extracts road objects from the road graph and which objects are collected. Some objects may take significant effort to extract and thus there's an option to disable collection of some of the types.
Electronic Horizon supports live incidents on a most probable path. To enable live incidents IncidentsOptions should be provided. If both graph and apiUrl are empty, live incidents are disabled (by default).
