Intelligent Transportation<\/h3>\n

\"\"<\/p>\n

As many as 270,000 vehicles per day use the I-80 corridor, one of the busiest transportation corridors in California\u2019s San Francisco Bay Area.<\/strong> Starting in July 2016, the California Department of Transportation (Caltrans) began activating elements of the I-80 SMART Corridor Project, a network of integrated electronic signs, ramp meters, and other state-of-the-art elements on the 20-mile stretch of highway between the Carquinez and Bay Bridges. This project implements one of the most sophisticated intelligent transportation systems (ITSs) in California and is designed to enhance motorist safety, improve travel time reliability, and reduce accidents and associated congestion.<\/p>\n

Scope Of Work<\/h3>\n

Parsons\u2019 scope of work on the project included system design, procurement, development, integration, testing, and training. As system integrator, we developed innovative enhancements to Caltrans\u2019 active traffic management (ATM) system to support ATM scenarios, adaptive ramp metering, and variable advisory speeds. We also served as the subcontractor coordinator, overseeing four subcontractors during the life of the project.<\/p>\n

Better Decisions On The Road<\/h3>\n

The most familiar elements of the project, such as variable speed and blocked lane signs, allow drivers to make informed decisions if an incident occurs. In addition, real-time ramp metering on 44 on-ramps reduces merging conflicts and manages traffic volumes. Other state-of-the-art elements of this elaborate project include:<\/p>\n
