Urban SDK provides data to stream-line and enhance traffic analysis, routing, and planning with live and historical data.

Traffic Speed Schema
The dataset is available in JSON, Shapefile, GEOJSON, and CSV file types.

Detailed Calculations
Travel Time
The expected travel time along the roadway; will not exceed the legal speed limit.
Confidence
The value of the confidence
field indicates the proportion of real time data included in the speed calculation. It is a normalized value between 5 and 40 with the following meaning:
confidence
= 5 indicates gap-filled speeds10 <
confidence
<= 15 indicates suggestive speeds20 <
confidence
<= 25 indicates highly suggestive speeds30 <
confidence
<= 35 indicates confident speedsconfidence
= 40 indicates highly confident speeds
This field can be used to identify whether the data for a location is derived from real time probe sources or historical information only.
funclass_id
The functional class is used to classify roads depending on the speed, importance and connectivity of the road.
Must satisfy: 1 ≤ value < 5
The value represents one of the five levels:
1: allowing for high volume, maximum speed traffic movement
2: allowing for high volume, high speed traffic movement
3: providing a high volume of traffic movement
4: providing for a high volume of traffic movement at moderate speeds between neighborhoods
5: roads whose volume and traffic movement are below the level of any functional class
