Transportation & Traffic Engineering

We design transportation systems that enhance mobility, safety, and connectivity through data-driven solutions and collaborative planning.

what we do

Our integrated transportation engineering services improve mobility for all users, enhance safety, and support sustainable long-term growth.

Smarter traffic solutions for our communities

We support projects from permitting and planning through ongoing traffic operations—delivering solutions that work today and adapt for tomorrow.

Highway Engineering

Roadway and intersection design, multimodal planning and design, and large culvert design and habitat connectivity.

Traffic Engineering

Traffic impact studies, signal and system design, modeling and simulations, safety analyses, and flow optimization.

Traffic Signal Operations

Traffic signal management, traffic data analytics, signal inventory and inspection, support, and training.

“The renderings developed by Sebago Technics were an invaluable part of the development of the Town of Orono’s Comprehensive Plan. They brought the community’s land use vision to life, and combined it with a previously developed transportation plan for a major corridor (also done by Sebago). Sebago’s work truly enhanced the ability to communicate complex ideas in a compelling and accessible way.”
