Governor Josh Shapiro (D) recently issued $30 million to 57 municipalities across Pennsylvania through the state’s Green Light-Go Program to improve traffic safety and mobility by reducing roadway congestion and improving traffic flow.

Overseen by the Pennsylvania Department of Transportation, that funding will support projects that upgrade traffic signal detection and control technology, allowing signals to respond to real-time traffic conditions, reduce congestion, and improve safety for drivers, pedestrians, and cyclists.
“Green Light-Go” grants are provided as reimbursements to municipalities for projects that improve the efficiency and operation of existing traffic signals. Eligible improvements include, but are not limited to, installation of light-emitting diode or LED systems, traffic signal retiming, special-event traffic planning, traffic signal monitoring, and upgrades to modern signal technologies.
[Editor’s note: A recent episode of ‘The DOT POD’ podcast produced by the New York State Department of Transportation went ‘Inside the Signal Shop’ to detail how NYSDOT crews maintain traffic signals, as well as the communications systems that tie everything together.]
“Our top priority is serving the people of our Commonwealth by improving the services that make a real difference in Pennsylvanians’ lives,” said Mike Carroll, PennDOT’s secretary, in a statement. “The safety improvements supported by the Green Light-Go program will help municipalities reduce congestion, improve traffic flow, and keep Pennsylvanians moving safely and efficiently.”
Other state departments of transportation are engaged in similar traffic technology improvement efforts.
For example, in September 2025, the Connecticut Department of Transportation unveiled plans to replace traffic signal controllers/cabinets and install cellular modems at select state-owned traffic signals statewide in 22 cities and towns.
The agency said that the design plans for this traffic signal project are expected to be completed in February with a tentative construction start date sometime in May.
