TPD's Traffic Signal Design Team has the manpower and specific knowledge to provide prompt response and expert service to satisfy all of our client’s traffic signal needs. Our Team is comprised of professionals from across the board, including former DOT staff, engineers, and designers with proven expertise in every aspect of traffic signal design, operations, structural analysis, coordination, permit plan compliance review and inspection. TPD’s signals managers are IMSA Level II certified and possess specialized knowledge in the differing aspects of traffic signal projects.

In the area of traffic signal design, TPD has invested a great deal of resources to make certain that our team is fully trained in the use of the latest software packages needed in the design and coordination of traffic signal systems to minimize congestion and keeping traffic moving along the corridor.

TPD provides traffic signal system design services for projects ranging from a single isolated intersection to corridors with over 50 signalized intersections in heavily-traveled central business districts. In terms of modernization, TPD is fully capable of incorporating the latest technologies in adaptive signal control, detection systems, and Ethernet-based fiber optic communications systems to allow for the interconnection of signals for better synchronization and information access.

Once traffic signal systems are operational, TPD's Traffic Signal Design Team works with municipalities, DOTs and other stakeholders to remotely monitor the operation of the system and help troubleshoot issues that may arise.
