Researchers at the University of California, Berkeley are working to increase freeway efficiency in a project called Connected Corridors. California's Bay Area and Los Angeles are tied for the second-worst traffic in the United States, and Connected Corridors aims to create technologies that will collect and analyze traffic data and make real-time, whole-system recommendations.
A prototype traffic-advisory system for an as-yet-unnamed commuting corridor is planned in the next three years.
Connected Corridors merges the Mobile Millennium project, which uses volunteer-supplied data from mobile phones to create a traffic-mapping application, with the Tools for Operational Planning project, which uses unique algorithms to model traffic. The combined program will rapidly assess traffic conditions and recommend a course of action for agencies that control the freeway and the nearby arterials.
Policy will factor into the project because various agencies might have conflicting interests. The model will feature a decision tree that rejects actions violating interagency agreements.
The project's software learns from experience by comparing predictions with historical outcomes to become more accurate over time.
In the second phase, Connected Corridors will add a public transportation component that will inform drivers of their route choices while they are in transit.
