SpeedReadingInterval

JSON representation
Speed

Traffic density indicator on a contiguous segment of a polyline or path. Given a path with points P_0, P_1, ... , P_N (zero-based index), the SpeedReadingInterval defines an interval and describes its traffic using the following categories.

Fields
`startPolylinePointIndex`	`integer` The starting index of this interval in the polyline.
`endPolylinePointIndex`	`integer` The ending index of this interval in the polyline.
Union field `speed_type`. `speed_type` can be only one of the following:
`speed`	`enum (Speed)` Traffic speed in this interval.

Speed

The classification of polyline speed based on traffic data.

Enums
`SPEED_UNSPECIFIED`	Default value. This value is unused.
`NORMAL`	Normal speed, no slowdown is detected.
`SLOW`	Slowdown detected, but no traffic jam formed.
`TRAFFIC_JAM`	Traffic jam detected.
