SpeedReadingInterval

  • SpeedReadingInterval indicates traffic density on a segment of a path using start and end points and a speed category.

  • The interval is defined by startPolylinePointIndex and endPolylinePointIndex, representing the segment's start and end points on the path.

  • Traffic speed within the interval is categorized using the speed enum, providing information about traffic flow.

  • When an index value is 0 in the JSON representation, the corresponding field (startPolylinePointIndex or endPolylinePointIndex) may appear unpopulated.

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. In JSON, when the index is 0, the field appears to be unpopulated.
endPolylinePointIndex

integer

The ending index of this interval in the polyline. In JSON, when the index is 0, the field appears to be unpopulated.
speed

enum (Speed)

Traffic speed in this interval.
