Los Angeles DOT selects Inrix to provide city with urban mobility intelligence


To improve its urban mobility, the Los Angeles Department of Transportation (LADOT) has selected Inrix’s Roadway Analytics system for instant and highly precise road performance analysis of the city’s congested road network.

According to the 2016 Inrix Global Traffic Scorecard, Los Angeles drivers spent an average of 104 hours last year in traffic jams during peak congestion hours, more than any other city in the world.

Inrix Roadway Analytics will provide Los Angeles staff with instant analysis of traffic patterns to maximize mobility improvement efforts and minimize costs. The cloud-based traffic analysis tool will help LADOT identify areas that benefit most from road improvements, reduce the cost of operations, and more accurately measure and report the impact of transportation investments.

Roadway Analytics will help LADOT manage its road network with access to on-demand data to analyze, visualize and understand performance without the need for additional technology investments. The city can also identify and compare locations that are operating sub-optimally to help prioritize road improvement efforts.

In addition, Roadway Analytics allows city planners to perform before and after studies to quantify and communicate the impact of road projects; monitor and identify performance trends on roadways; produce and report key performance indicators on travel times and congestion reduction; and monitor, compare and adjust construction zones to minimize the impact on traffic flow.

LADOT will use various feature of the Roadway Analytics platform, including:

• Performance Charts, which produces line and bar graphs, enabling before and after studies and/or comparisons of roadways with visualizations to communicate findings;

• Congestion Scan uses heat maps to identify problem areas along a road, helping LA pinpoint the location of congestion to better target improvement efforts;

• Trend Maps is a visual communication tool that illustrates the impact of roadway conditions throughout the day;

• Bottleneck Ranking identifies hotspots or congested corridors during a specific analysis period within an area, and provides a ranking by determining the number of occurrences, length and duration of each jam;

• Data Downloader enables users to directly query Inrix XD Traffic speed archive data from 24 hours prior for any road segment and/or time period.

“Like many cities, traffic in and around Los Angeles has far-reaching impact, not only on commuters, but also to our economy and the environment,” said Tim Fremaux, LADOT transportation engineer. “With Inrix Roadway Analytics, we’re taking the necessary steps to maximize our efforts to move people and goods through our city.”
