A transportation engineer designs and improves roads, intersections, bridges, transit and drainage so people and goods move safely. Most people enter with an ABET-accredited bachelor's degree in civil engineering, pass the FE exam, work under a licensed Professional Engineer (PE) for about four years, then take the PE exam. This roadmap takes you from the core math and physics, through the design and analysis tools employers screen for (Civil 3D, Synchro, HCM, GIS), to advanced work in safety analysis, simulation and project leadership. Everything here is free to learn. You will build a portfo

Stage 1 of 3 · about 16 weeks
Understand how traffic and roads work, and build the math, statics and CAD habits every transportation job assumes.
Engineering math and physics for roads
Every design decision, from stopping distance to curve radius, is physics plus algebra. If you can do the math by hand, you can spot when software gives a wrong answer.
Traffic flow fundamentals
You cannot fix congestion until you can describe it. Flow, speed and density are the three numbers behind every traffic study, and the Highway Capacity Manual builds on them.
Basic CAD and Civil 3D
Plans are the product of the job. Entry-level engineers spend much of their first years drafting and checking drawings, so CAD fluency gets you hired.
Reading design standards
Engineers do not invent rules. They apply AASHTO, state DOT manuals and the MUTCD. Learning to find the right section fast is a daily skill.
Technical writing and Excel
Your top skills in the job are writing, reading and critical thinking. Reports, memos and cost estimates go to clients and the public, so clear and accurate writing earns trust.
