Henning Schulzrinne, who previously served as chief technology officer at the Federal Communications Commission, will return to FCC as CTO and senior adviser for technology at the agency’s office of strategic planning and policy analysis.

Schulzrinne will succeed FCC CTO Scott Jordan, who is set to leave the agency in December, FCC said Wednesday.

“With complex technical challenges such as broadband privacy and confronting robocalls and spoofing, I am grateful both that Henning has agreed to return and that he and Scott will overlap for a time,” said FCC Chairman Tom Wheeler.

Schulzrinne joined FCC in 2011 as chief technologist and has continued as a part-time adviser when he left the agency in 2014.

He contributed to the development of the voice over internet protocol and Session Initiation Protocol and currently serves as Levy professor of electrical engineering and computer science at Columbia University’s Fu Foundation School of Engineering and Applied Science.

Jordan was appointed CTO at FCC in 2014 after he served as computer science professor at the University of California in Irvine.

Wheeler said Jordan has agreed to extend his stay at FCC to continue his work on broadband privacy and set-top box proceedings.

The Transportation Department, White House and National Highway Traffic Safety Administration have issued a call to action that seeks to engage stakeholders in efforts to address the 7.2 percent increase of traffic fatalities in 2015 through the use of data.

NHTSA will give access to its Fatality Analysis Reporting System to safety partners, government officials, technologists, data scientists and policy experts that can help identify factors that led to the increase, DoT said Monday.

A White House release stated the joint effort wants organizations, technology companies and the public to analyze NHTSA’s data and help determine the potential impact of economic conditions, climate change, driving behavior and public health on traffic-related accidents.

The White House added mobility analytics company StreetLight Data; location intelligence provider CARTO; traffic and navigation app company Waze; and mapping platform Mapbox have made separate data sharing and tool development commitments to support the call to action.

NHTSA said the rise in fatalities could be caused by increased driving due to job growth and low fuel prices and that human factors contribute to majority of the accidents.

The Congressional Budget Office has said a Senate bill that would require the Treasury Department and the Export-Import Bank to submit annual reports on the sale of commercial planes and aircraft parts to Iran would result in an increase in annual administrative costs at both institutions by less than $500,000.

CBO said in the report published Wednesday the Stop U.S. Support for State Sponsors of Terrorism Act would result in the application of pay-as-you-go procedures since its passage could raise direct spending and revenues due to potential expansion of prohibited forms of trade with Iran.

According to the report, the proposed legislation seeks to amend the existing law in order to restrict the Treasury to issue licenses for the export of commercial passenger planes to Iran and includes a private-sector mandate as stated in the Unfunded Mandates Reform Act since the bill contains a prohibition that would affect U.S. aircraft producers.

“CBO estimates that the aggregate cost of the mandate would probably exceed the annual threshold established in UMRA for private-sector mandates ($154 million in 2016, adjusted annually for inflation),” the report said.

CBO added that the enactment of the bill would not result in on-budget deficit growth “in any of the four consecutive 10-year periods beginning in 2027” and would not affect the Export-Import Bank’s lending operations.
