Freeway Travel Time - Traffic
Contains travel times and traffic conditions collected from road-side sensors for freeways throughout Melbourne. The data includes (where available)the spatial location of the freeway, actual travel time, nominal travel time, rounded travel time, travel time variance, average speed, traffic conditions, congestion index, delay and excess delay. The source data is updated every 30 seconds. To obtain an 'API Key' please continue to signup using our Data Exchange Platform (https://data-exchange.vicroads.vic.gov.au/).

|---|---|---|---|---|
| type | Type | Fixed Value: FeatureCollection. | ||
| features | Features | Array of Feature object. Refer to Feature object details. | ||
| feature | Feature | Each named freeway and freeway segment is represented as a single feature in GeoJSON. | ||
| feature.type | Feature Type | Fixed Value: Feature. | ||
| feature.geometry | Feature Geometry | The geometry of the feature. Refer to Geometry object details. | ||

| geometry.type | Geometry Type | Fixed value: LineString. | ||
| geometry.coordinates | Geometry Coordinates | Coordinates are in x, y order (longitude, and latitude for geographic coordinates) precisely in that order and using double values. Altitude or elevation MAY be included as an optional third parameter while creating this object. Example: {"type": "LineString","coordinates": [[100.0, 0.0],[101.0, 1.0]]} | ||

| properties.variancenominal | Variance Nominal | The variance of the actual travel time from the nominal travel time. | ||
| properties.datasubstitution | Data Substitution | The percentage level of interpolation that has been applied to missing movement data. The percentage is measured as a percentage of the length of the path that has been interpolated against the total distance. | ||
| properties.includesrampwaittime | Includes Ramp Wait Time | Indicates whether the ramp wait times are included in the travel time measures in the case where the travel time path is from a sign associated with an on-ramp. | ||
| properties.congestionindex | Congestion Index | The congestion index for the travel time path. This applies only to travel time paths from remote systems, and is calculated by the remote system. | ||
| properties.delay | Delay | The delay for the travel time path. This applies only to travel time paths from remote systems, and is calculated by the remote system. | ||
| properties.excessdelay | Excess Delay | The excess delay for the travel time path. This applies only to travel time paths from remote systems, and is calculated by the remote system. | ||
| properties.orderonparent | Order On Parent | The order on the parent path, if it is a sub-path. | ||
| properties.source | Source | An object that describes information source. Refer to Source object details. |
