Agencies in 20 states use INRIX Signal Analytics to identify and reduce excessive delays and emissions

Today, INRIX, Inc., a leader in transportation analytics and connected car services, announced that agencies in 20 states who collectively monitor more than 10,000 signalized intersections are leveraging INRIX® Signal Analytics to make managing signal and corridor performance easier, faster, and cheaper. Signal Analytics delivers unsurpassed intersection and corridor analytics in an easy-to-use yet powerful cloud-based platform designed for all levels of traffic professionals – management, engineering, operations, and maintenance.

“We’re thrilled to support the city, state, and MPO agencies of all sizes across the country who share the same goal to provide safe mobility, while also minimizing delay, energy, and environmental impacts,” said Scott Sedlik, senior vice president and general manager of public sector at INRIX. “With Signal Analytics, every transportation agency in America can monitor and manage the performance of their entire traffic signals network far cheaper than traditional hardware and physical sensor systems.”

Agencies across Arizona, California, Delaware, Florida, Idaho, Illinois, Maryland, Massachusetts, Michigan, Nebraska, Nevada, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Rhode Island, and Washington have tapped INRIX to monitor the performance of all approaches and movements at signalized intersections to improve the efficiency of their key corridors, critical arterials, and city centers. Specific agency use cases include:

• Florida DOT selected Signal Analytics for its statewide arterial management program to improve the safety and efficiency of its road network
• LA Metro is using Signal Analytics as part of their planning and performance monitoring effort on three key freeways in Los Angeles County that will be using Integrated Corridor Management (ICM) strategies to address on-recurrent congestion.
• Washington County (Portland, OR) uses INRIX to prioritize system enhancements, which has resulted in a 30% reduction in delay after retiming, and to validate citizen complaints.
  

Signal Analytics is the industry’s first intersection analytics platform based exclusively on anonymous connected vehicle data. The cloud-based application calculates industry-defined metrics including control delay, split failures, stops, and turn ratios at a far lower cost than instrumenting each intersection with equipment. New trajectory plots allow users to visualize vehicle paths for every approach or movement at any intersection available within the tool.

Leveraging vehicle movement data from more than 100 million trips and a billion miles daily, Signal Analytics delivers every metric necessary for operators to fully understand performance on nearly 250,000 signalized intersections across the U.S. Customizable daily, weekly, and monthly reports and dashboards highlight key metrics, problems, and trends for intersections and corridors across a road network. In-depth searches and advanced functionality, such as user-defined date(s) and time periods, leverage the Center for Advanced Transportation Technology (CATT) Laboratory at the University of Maryland’s powerful Regional Integrated Transportation Information System (RITIS) platform.

Reducing excessive delay has the direct and immediate benefit of reducing carbon emissions from unnecessary idling at intersections. INRIX calculated each second of delay reduced across signals nationwide would translate into 800,000 fewer metric tons of CO2 emitted annually. The recently passed Bipartisan Infrastructure Law contains more than $1.2 billion annually for DOTs to reduce the surface transportation system’s carbon footprint. Signal Analytics is a cost-effective tool to reduce emissions quickly and help ensure continued emission reductions by reducing needless vehicle idling. Signal Analytics qualifies under multiple eligible project categories of this new Carbon Reduction Program.
