Struct TrafficFlowData 

pub struct TrafficFlowData {
    pub shape_coordinates: Vec<GeographicCoordinate>,
    pub current_speed_kilometers_per_hour: Option<f64>,
    pub free_flow_speed_kilometers_per_hour: Option<f64>,
    pub congestion_level: TrafficFlowCongestionLevel,
}

Flow condition for one road segment (or polyline of road segments) inside the queried box, in kilometers per hour when the provider reports speeds and as a congestion classification otherwise.

Fields

shape_coordinates: Vec<GeographicCoordinate>

Segment geometry, ordered along the road.

current_speed_kilometers_per_hour: Option<f64>

Currently observed speed in kilometers per hour, when reported.

free_flow_speed_kilometers_per_hour: Option<f64>

Unconstrained (free-flow) speed in kilometers per hour, when reported.

congestion_level: TrafficFlowCongestionLevel

Congestion classification from the speed ratio or provider buckets.

Implementations

impl TrafficFlowData

pub fn from_speeds( midpoint_coordinate: GeographicCoordinate, current_speed_kilometers_per_hour: f64, free_flow_speed_kilometers_per_hour: f64, ) -> Self

Builds one single-point flow observation, deriving the congestion classification from the current-to-free-flow speed ratio.

pub fn from_congestion_level( shape_coordinates: Vec<GeographicCoordinate>, congestion_level: TrafficFlowCongestionLevel, ) -> Self

Builds one polyline flow observation where the provider reports only congestion buckets and no speeds (MapQuest JSON flow, for example).
