Traffic speed along the path from the previous waypoint to the current waypoint.
SpeedReadingIntervalLog
Traffic density indicator on a contiguous segment of a path. Given a path with points P_0, P_1, ... , P_N (zero-based index), the SpeedReadingIntervalLog defines an interval and describes its traffic using the following categories.
[null,null,["Last updated 2025-08-27 UTC."],[],["The provided content defines how traffic density is represented along a vehicle's path using `SpeedReadingIntervalLog`. This log contains an array of intervals, each described by a `startPolylinePointIndex` and `endPolylinePointIndex` indicating its position within the path. Each interval also has a `speed` field, which is an enumeration indicating the traffic speed within that segment. The `speedReadingInterval` is an array of these objects, showing all segments in a given trip.\n"]]
