Detailed Information

About Me: 

Dr. Arhin is an Assistant Professor in the Civil and Environmental Engineering Department at Howard University where he teaches several transportation and traffic engineering courses. He has managed several research projects for the District of Columbia and others, with an annual average research budget of $1.5 million since he joined the Center in 2001. Dr. Arhin has conducted several safety studies which have led to several implementations in DC, particularly, the evaluation of countdown pedestrian signals in DC (which led to the citywide installations) and the HAWK Signal at Georgia Avenue and Hemlock Street to improve pedestrian crossing at the intersection. He is a registered Professional Engineer (PE) in DC, MD and VA; a registered Professional Traffic Operations Engineer (PTOE), and a PMI-certified Project Management Professional (PMP). He is the current President-elect of the DC Society of Professional Engineers.

Dr. Stephen Arhin has 19 years of experience in all facets of traffic/transportation engineering that includes traffic safety and operations, planning and Intelligent Transportation Systems. He has extensive experience working with state and local transportation agencies on a wide variety of safety, operations, and design projects. Prior to becoming a faculty member and starting his transportation consulting firm, he was a Senior Traffic/Transportation Engineer with nationally-recognized engineering consulting firms (Baker Engineers, LPA Group, Daniel Consultants, RBA Group and others). In 2014, he was part of the team that prepared the DC Speed Safety Nexus for the District of Columbia. Dr. Arhin co-authored DC’s first Traffic Calming Policies and Guidelines and Work Zone Manual (through DDOT’s Research Program) and has been involved in a substantial number of safety projects in the District as well as in jurisdictions in the metropolitan area. Due to his background and prominent role in improving safety in the District, he was selected to serve on the DC Council Safety Improvement Panel in 2012.
