Traffic Signal Design

Traffic Signal Design for MDOT

Maryland State Highway Administration

Since 1995, Brudis & Associates, Inc. has been working with the Maryland State Highway Administration’s Traffic Engineering Design Division, providing engineering services for new and modified signals throughout the state. The services involved in this project have included field investigations, the establishment of associated traffic control device needs, and the determination of safety standards and funding requirements.  Several of these signal designs were classified by the Maryland Department of Transportation (MDOT) as “STAR” projects, which required design services to be completed within one week of initial notification.

Traffic Signal Design for DDOT

District Department of Transportation

Under two consecutive, three-year agreements, Brudis & Associates, Inc. provided traffic engineering services for the District of Columbia Department of Transportation, IPMA.

Traffic Signal Design for Baltimore County, Maryland

Baltimore County Department of Public Works

Under two consecutive agreements with Baltimore County Department of Public Works, Bureau of Traffic Engineering & Transportation Planning, Brudis & Associates, Inc. successfully completed traffic signal design  and traffic engineering analysis services.

Traffic engineering tasks involved preliminary studies/concept plans, and final construction plans.  A summary of BAI’s traffic signal designs included the development of complete construction plans, specifications, utility coordination and cost estimates at multiple intersections throughout the county.

Francis Scott Key Mall Holiday Signal Timing

Frederick County Division of Public Works

Brudis & Associates, Inc. provided traffic analysis to optimize the traffic signal system timing parameters around the Francis Scott Key Mall (along Spectrum Drive and Lowe’s Lane) for the Winter Holiday season.  BAI conducted manual and machine traffic counts and created a Synchro Model to develop intersection and system timing along the Spectrum Drive corridor. BAI also prepared an analysis of truck traffic and made recommendations for truck restrictions to optimize traffic flow. 

BAI supervised the signal construction and trained field personnel for both the phasing change to signalized intersection and the changes to the controller.
