Iteris performance measurement system to manage traffic on California’s I-405 Improvement Project

One of the USA’s leading suppliers of applied informatics systems for the transportation industry, Iteris Inc., has been awarded a further expansion of its role on the I-405 Improvement Project in southern California, one of the largest infrastructure programs currently underway in the USA.

Undertaken by the Orange County Transportation Authority (OCTA) in cooperation with the California Department of Transportation (Caltrans), the I-405 Improvement Project is a massive redevelopment and widening of a 16-mile (25.8km) long section of the San Diego Freeway (I-405) between State Route 73 (SR-73) and Interstate 605 (I-605).

The multi-year improvement project also includes the addition of dynamically-priced tolled Express Lanes, with the entire scheme due to be completed in 2023. The project is being delivered by OC 405 Partners, a joint venture (JV) between OHL USA Inc. and Astaldi Construction Corporation, in conjunction with exclusive subcontractors, Myers and Sons Construction, and All American Asphalt.

Since the I-405 Improvement Project’s launch in March 2017, Iteris has supported work on freeway intelligent transportation system (ITS) and 405 Express Lanes infrastructure design, temporary ITS infrastructure for use during construction, development of the project traffic management plan, and signal design.

In May 2018, the company was subsequently awarded a US$2.4m contract to deploy temporary ITS infrastructure for use during construction, bringing its total contract awards so far to US$8.1m. Iteris has now announced that OC 405 Partners will use its iPeMS (Iteris Performance Measurement System) cloud-based Software as a Service (SaaS) platform as part of the I-405 Improvement Project, supporting its traffic management operations during construction.

In combination with real-time and historical traffic data from Here Technologies, iPeMS will give OC 405 Partners the ability to analyze and visualize traffic data to manage congestion, safety and mobility for 370,000 daily southern California road users for an initial 12-month period during the construction phase of the US$1.9bn project. The project’s iPeMS features include:
• Real-time congestion maps to support maintenance of traffic during construction;
• Bottleneck monitors to identify construction-related problem areas;
• Graphical representations of traffic conditions to analyze events and optimize response plans;
• Historical trend and route reports, maps and congestion charts to track reliability and support planning of project detour routes in and around the cities of Costa Mesa, Fountain Valley, Huntington Beach, Westminster and Seal Beach.

The proven Iteris iPeMS software is able to manage, measure and optimize complex transportation networks, and is currently in use by several government agencies and municipalities throughout North America, including those in California, Utah, Virginia, Oregon, and Toronto.

“We are excited to further expand our role in this vital initiative that will ultimately make roads safer and more efficient for residents and commuters in Orange County and the Los Angeles County area,” said Scott Perley, vice president of transportation systems at Iteris.

“iPeMS will provide real-time and historical traffic data that will offer actionable insights to support safe mobility and traffic management operations during the construction phase of this historic project.”
