Traffic information and connected driver services provider Inrix said its crowd-sourced traffic network has become the largest network in the world across public sector, automotive and mobile businesses, after doubling its customers in 2011.

Bryan Mistele, Inrix president and CEO, said the company is the fastest growing traffic intelligence platform in the world.

"We are setting the standard for leveraging Big Data to solve transportation issues worldwide," Mistele added.

The company said that twenty five US State Departments of Transportation are using their services for daily operations, traveller services or congestion performance measures.

The traffic intelligence platform of the company delivers better coverage at 25% of the per mile lifecycle cost, with the added ability to reduce user delay costs by up to $100,000 per incident, according to the company.

The company also signed deals with more than 50 customers in 2011, and has launched traffic services for next-generation two-way connected navigation with Toyota, as well as Audi and BMW, in Europe. Collaboration between Inrix and Ford expanded, with the convergence of automotive and mobile markets and SYNC Destinations, a smartphone application offering reliable traffic forecasts to the drivers.

The application enables users to send future destinations directly from their phone to their car. Inrix’s real-time traffic information is used by 20 automakers worldwide.

The company also powered eight iPhone traffic navigation applications in North America, while in Europe Inrix traffic intelligence fuels mobile applications from Bosch, Garmin, Navigon, Sygic and Telmap.

The company is making efforts to come up with breakthrough designs to reduce the economic, environmental and individual toll of gridlocks. Inrix has further expanded its customer base by acquiring European traffic provider IT IS.
