City of Austin Signal Timing Data Analysis

The City of Austin is well-known as a focal point for technological innovation. When traffic almost disappeared due to the widespread lockdowns from COVID-19, the City looked to Kimley-Horn and transportation technology solutions to collect and analyze traffic data to understand the effects of this sudden change in traffic patterns.

With more than 33 critical corridors, 1,000+ signals, and 600+ cameras, Kimley-Horn helped Austin’s Mobility Management Center (MMC) leverage big data analysis tools to gain insights quickly and adapt accordingly. This data was complemented by the use of Kimley-Horn’s KITS Smart Cities software. Our data-driven and proactive approach improving signal timing operations for the City during the pandemic led to the recommendation to use the off-peak traffic plan all day due to low traffic volumes. This approach saved the citizens of Austin time, resulting in more than $2.8M in benefit. In total, the Kimley-Horn team made changes to 856 traffic signals and 571 school zone flashing beacons. The team then used this data to implement a tailored plan to return traffic to normal.
