CONNECTED SIGNALS, CITY OF SAN JOSE, BMW AND ARGONNE NATIONAL LABORATORIES LAUNCH DOE-SUPPORTED SAFETY AND EFFICIENCY STUDY

July 5, 2016 — With support from the US Department of Energy’s Small Business Vouchers Pilot program, Connected Signals is beginning a study to evaluate the safety and efficiency implications of providing drivers with real-time, predictive information on the state of traffic signals.

Working with the City of San Jose, CA, Argonne National Laboratories, and BMW, roughly four hundred drivers will be recruited. Over an approximately six-month period, their urban driving behavior will be analyzed with and without access to live, predictive traffic signal data, including time-to-green and green-wave speed recommendations. A variety of indicators of fuel efficiency, greenhouse gas production, and safety will be collected and analyzed to determine effects on safety and efficiency. The indicators will include acceleration, braking, red-light arrivals, and red-light wait times.

The study will collect and use data from a significant number of actual drivers during their normal driving activities, both with and without access to traffic signal data. The collected data will then be used to compute reliable fuel savings and safety impacts, augmenting existing estimates based largely on anecdotal observations, analytic modeling, and small-scale studies. The conclusions drawn will provide automakers and government agencies with objective bases for decision-making regarding connected vehicles in general. Click here to learn more or participate.
