Signalization Upgrade for the City of Harrisburg – Dauphin County, Pennsylvania
Herbert, Rowland & Grubic, Inc. (HRG) was responsible for the design and construction phase services associated with upgrading twenty-two traffic signals and designing one new traffic signal at various intersections within downtown Harrisburg.
In order to make use of available funding, HRG grouped the signals into five corridors and phased the design and construction of each corridor over a period of several years.
In designing these signalization upgrades, HRG conducted capacity analyses for each corridor. In addition, we conducted manual turning movement counts and performed queue analyses to determine the storage length required for auxiliary lanes. Each signal was then interconnected and coordinated with the existing signal system using overhead or existing underground ducts.
In designing these signalization upgrades, HRG worked with the City of Harrisburg to provide signal coordination and hardwire interconnect between signals and communication back to a central location.
To preserve the nostalgic quality of the area, HRG designed ornamental fixtures and nostalgic lighting on the signal supports along the Maclay Street and Market Street Corridors.
