Traffic Signals, Management
PennDOT plays an active role in keeping people and goods moving through the state. Whether it's ensuring traffic management procedures and best practices are followed, or providing assistance to local governments for traffic signals, the department has many resources available.
For example, information on funding programs, engineering, design, and more is available through PennDOT's Traffic Signal Portal.
Flashing Yellow Arrow
PennDOT is implementing a new type of traffic signal to provide a safer, more efficient left turn for motorists. The flashing yellow arrow indication is a new type of display that will replace the circular green indication for left turns at signalized intersections.
The signal is more intuitive to motorists and, according to national data, can reduce left-turn crashes by as much as 20 percent!

Green Light-Go reimbursement grant awards can be used on existing traffic signals to installing light-emitting diode (LED) technology, performing regional operations such as retiming, developing special event plans and monitoring traffic signals, as well as upgrading traffic signals to the latest technologies.
Act 101 of 2016 recently provided updates to the program by reducing the applicant match to 20 percent, expanding eligible applicants to planning partners and counties, and allowing all projects to be led by applicants. Green Light-Go was made possible by Act 89, the far-reaching transportation plan adopted in November 2013.
Editor's Note: Following is a county-by-county list of Green Light-Go Round 3 funding recipients, the amount of state funding, and a brief description of the projects. Note the state funding represents only part of the total project funding:
