Roads Management Insights is a geospatial analytics product that accepts user-defined
routes to provide trip duration and speed reading intervals data. This data is
available as periodically collected data to build long-term analysis datasets
and as near real-time data for event updates.
Why use Roads Management Insights?
With Roads Management Insights, you can use road data to develop solutions for managing
road networks and address challenges in transportation and public utilities.
These solutions drive improvements in road safety, efficiency, and
sustainability.
The following are examples on how you can use Roads Management Insights:
Develop systems to identify and mitigate high-risk road segments with
the objective of reducing road crashes and injuries.
Design traffic pattern analysis tools to optimize road network flow,
reduce congestion, and shorten travel times.
Build applications that analyze traffic patterns to identify correlations
with vehicular emissions, contributing to air quality improvements and
sustainable urban planning.
What you can do with Roads Management Insights?
You can use the Roads Management Insights to include the following capabilities in your
applications:
Create, manage and analyze custom routes datasets: Accumulate routes data
over time using BigQuery.
Access near real-time road condition updates: Receive live streams of data
using Pub/Sub.
How Roads Management Insights works
Roads Management Insights provides road data by integrating the Roads Selection
API, BigQuery, and Pub/Sub.
Use the Roads Selection API to begin collecting road data by defining and
submitting specific routes. This API accepts requests containing latitude
and longitude coordinates that specify origins, destinations, and intermediate
waypoints for a route.
The API then validates the submitted routes against criteria such as
jurisdiction and road utility. Upon validation, the API begins sending
continuous updates of the following road data for the selected routes:
Trip duration: The calculated travel time for a route. This includes
both the traffic-aware duration, which accounts for current traffic
conditions, and the static duration, which is traffic-unaware.
Speed reading intervals: The traffic density indicator on a route. This
data indicates if vehicles on the route are traveling at a normal speed with
no traffic delays, if there is a slowdown detected with medium amount of
traffic, or if there are considerable traffic delays.
You can access this data though your Google Cloud project through two main
channels:
BigQuery: Accumulated road data is available in dedicated BigQuery
tables. This data includes travel duration, speed reading intervals (SRIs),
and route geometry for each selected route. These
tables are shared with your project through a private data exchange in
BigQuery (Analytics Hub).
Pub/Sub: Near real-time traffic updates every 2 minutes. These updates
are available in a dedicated Cloud Pub/Sub topic associated with your
project. Each message contains traffic details such as travel duration and
speed reading intervals in a defined Protobuf format.
