The comment resolution committee resolved all comments
from the first recirculation of the ballot, and the P2450/D5-IEEE
Draft Standard for the Performance of Down-the-Road Radar
Used in Traffic Speed Measurements was submitted to IEEE SA
Standards Board for approval in the RevCom meeting held on
March 21, 2019, in Munich, Germany. The draft standard was
disapproved by RevCom, who recommended that the draft
standard be recirculated once again. RevCom assembled a group
of mentors to advise the working group in the recirculation.
Under the mentorship of RevCom, the draft standard was
recirculated a second time. The results of the second recirculation were roughly 38:2 to approve, and four comments were
received. The comment resolution committee resolved all
comments from the second recirculation of the ballot.
After the comments from the second ballot recirculation
were resolved, the P2450/D6-IEEE Draft Standard for the
Performance of Down-the-Road Radar Used in Traffic Speed
Measurements was submitted to RevCom for their June 12,
2019 agenda in Panama City, Panama. On June 12, 2019, RevCom approved the draft standard and recommended it for
publication to IEEE-SA.
Following RevCom's recommendation, IEEE-SA approved
the draft for publication, and on November 5, 2019, the 24502019-IEEE Standard for the Performance of Down-the-Road
Radar Used in Traffic Speed Measurements was published.
The project P2450 is currently in Stage 6 (maintaining the
2450-2019 standard) of the standards development lifecycle.
Per IEEE-SA policy, the standard has a validity period of ten
years during which it may be amended, corrected or revised.

Project 2452
In December 2016, the TC-41 submitted a PAR to initiate a
new IEEE standards project for the performance of lidar systems used in traffic enforcement. In February 2017, the IEEE

approved this request, and P2452 Standard for the Performance of Lidar Used in Traffic Speed Measurements was
established with John Jendzurski as the chair. The P2452 PAR
expires on December 31, 2021.
To support the development of the lidar performance standard, the Lidar Working Group was formed to develop the
P2452 and chaired by John Jendzurski. A call for working
group members was sent out to various IEEE societies, and the
Lidar Working Group grew to an international participation
level with 31 members from government, industry, academia,
and test laboratories.
The Lidar Working Group had a kickoff meeting on August
5, 2019. The Lidar Working Group is currently in the process of
drafting the lidar performance standard.

Future Activities
TC-41 will continue to develop the P2452 Standard for the Performance of Lidar Used in Traffic Speed Measurements and
maintain 2450-2019-IEEE Standard for the Performance of
Down-the-Road Radar Used in Traffic Speed Measurements.
Although the work to this point been focused on technologies
for vehicle speed measurement, TC-41 is not limited to this
area. There has been some discussion in the TC-41 to address
other technologies used in traffic enforcement such as bloodalcohol-content measurement devices, red light cameras, and
school-bus-violation cameras.
John Jendzurski (john.jendzurski@nist.gov) is an Electrical
Engineer at National Institute of Standards and Technology
(NIST) where he conducts research and standards development in through-barrier and traffic enforcement radar. He is
currently the Chair of TC-41-Traffic Enforcement Technologies, the committee responsible for performance standards in
down-the-road radar and lidar used for traffic enforcement.
