SpeedReadingInterval

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

  • It classifies traffic speed into categories: NORMAL, SLOW, and TRAFFIC_JAM.

  • The interval is represented in JSON format including start/end point indexes and speed information.

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.
The type of speed in this interval. The following is a list of mutually exclusive fields. At most one of the fields will be set in a response:
speed

enum (Speed)

Traffic speed in this interval.
End of mutually exclusive fields.

Speed

The classification of polyline speed based on traffic data.

Enums
SPEED_UNSPECIFIED Default value. This value is unused.
NORMAL Normal speed, no traffic delays.
SLOW Slowdown detected, medium amount of traffic.
TRAFFIC_JAM Traffic delays.
