Insights Traffic Speed Analysis provides you with a comprehensive speed reporting tool to analyze speeds on all roads in your county, municipal or custom boundary.
Traffic Speed analysis reports are organized by:
Boundary: Roads within a Municipal Boundary or Census Tract
Month: Selected month of recorded speed data
Layers: Aggregated datasets
Average Speed: Determined by averaging all of the traffic speeds per roadway segments.
85th Percentile Speed: Determined by 85 percent of the traffic speeds observed to travel under free-flowing conditions per roadway segments.
Roadway Segment Analysis Report
When you select a road segment, a report for that month and road will open.
The report includes analytics metrics for:
Average Speed by Hourly Periods
Percentile Speed by Hourly Periods
Speed Comparison by Month
The report includes analytics for
85th Percentile Speed
Speed Category: This is the Urban SDK estimated Posted Speed Limit.
95th Percentile Speed
AM Peak 85th Percentile Speed
Example Roadway Segment Analysis includes:
The Roadway Segment Analysis is designed for users to quickly analyze traffic speed and safety hotspots on a particular roadway segment.
Traffic Calming and Public Complaints:
Use Case: View 85% speed data on road classes 1-7 within the municipal boundary.
Benefit: Efficiently validate the validity of public complaints before sending a team member or consultant to collect roadway data.
Pre and Post Implementation Analysis:
Use Case: Analyze the impact of new measures implemented in the community.
Benefit: Assess the effectiveness of measures not only on individual roadways but also on the surrounding community.
Safety and Hotspot Identification:
Use Case: Identify correlations between crashes and speeding incidents.
Benefit: Overlay local and state crash data to pinpoint areas with high rates of speed and crash clusters.
Data Sharing and Reporting:
Use Case: Generate automated monthly reports for each road segment.
Benefit: Simplify communication with council members and stakeholders, providing clear insights into community status and aiding in the allocation of capital funds.

Travel Time Reliability
Layer Name: Average Speed
Description: Determined by averaging all of the traffic speeds per roadway segments. Speed limit is determined by reported limit or free flow of traffic.
Layer Name: 85th Percentile Speed
Description: Determined by 85 percent of the traffic speeds observed to travel under free-flowing conditions per roadway segments. Speed category is determined by posted speed limit or free flow of traffic when no post speed limit is available.
Below (yellow) - Below normal is determined by values -9.99 and lower than the speed limit.
Normal (green) - Normal is determined by values close to the speed limit.
Above (red) - Above normal is determined by values +9.99 and above the speed limit.
County - Geographic region of a country used for administrative or other purposes in some modern nations.
Census Tract - Geographic area roughly equivalent to a neighborhood established by the Bureau of Census for analyzing populations.
Custom - Geo-specific boundary for organizations that oversee multiple counties, MPO, DOT District or custom areas. Urban SDK can implement custom zone types upon request.
Overnight: 12 am - 3:59 am
Early Morning: 4 am - 6:59 am
AM Peak: 7 am - 9:59 am
Midday: 10am - 12:59 pm
Early Afternoon: 1pm - 3:59pm
PM Peak: 4pm - 6:59pm
Evening: 7pm - 11:59pm
Tooltip Info for Extended Score Card
When you hover over a road segment, we will display a hover tooltip for details including:
Road Segment ID- A unique identifier for the road segment
Name - The name of the road.
Functional Class - The functional classification of the road.
Speed Category- Generally indicated on posted speed limit or traffic sign reflecting the maximum permitted speed in mph on the roadway segment. If no posted speed limit is available, we refer to freeflow speed based on 85th Percentile speeds.
Average Speed - Generally indicated as the mean rate of speed on the roadway segment.
85% Percentile Speed - Generally indicated to show speed at or below 85 percent of drivers travel on the roadway segment.
95% Percentile Speed - Generally indicated to show speed at or below 95 percent of drivers travel on the roadway segment.
Where does the data come from?
We acquire data from vehicle telematics and connected vehicle sources aggregated by OEM manufacturers.
Our data is the same as used by the FHWA The National Performance Management Research Data Set (NPMRDS) Source
We are happy to validate our dataset against ground truth or recent speed studies.
How much historical data is available?
Accounts will have a minimum of 13 months historical data from the day a new account is created.
Urban SDK can provide historical backfills upon request.
Can I filter the time period ranges?
Currently, you can filter by month.
We have roadmap plans to allow for hourly periods.
Are the legends customizable?
No, legends are static. Custom legends are available by exporting data to a Studio map.
Where does Speed Limit come from?
The posted speed limit or if no posted speed limit is available, we display the record freeflow speed for the date range.
Can you select multiple links?
Not currently but is on the roadmap to allow users to create custom routes of multiple road segments on the same roadway.
