Stantec’s Susan Langdon Named Transportation Engineer of the Year


Susan Langdon, PE, PTOE, a principal within Stantec’s Transportation practice, was named Transportation Engineer of the Year by the Texas District of the Institute of Transportation Engineers (TexITE). The award honors one engineer each year for outstanding practice, teaching, or research of the science and art of transportation engineering in Texas.

ITE is an international association of transportation professionals, including transportation engineers and planners, consultants, educators, technologists, and researchers, who work to improve mobility and safety for all transportation system users and help build smart and livable communities.

Langdon is an ITE fellow and has served the association in several capacities, including past president for TexITE and current executive board member for the ITE Traffic Engineering Council (TENC). A thought leader in traffic signal design, she also served as a panel expert for developing the Federal Highway Administration’s (FHWA) Signal Timing Manual, 2nd Edition, and she is currently an officer for the Transportation Research Board (TRB) Traffic Signal Systems Committee.  

 “This is a great honor for Susan to be recognized for her leadership and commitment to advancing innovative transportation solutions for our communities in Texas and throughout the nation,” said Cliff Hall, vice president and transportation business leader for Stantec’s South Central region.

Langdon received her bachelor of science in civil engineering from the University of Wisconsin. She is a professional engineer (PE) in multiple states and a certified professional traffic operations engineer (PTOE).
