The short answer
Tráfego with e commonly refers to the movement of vehicles, people, or data through a system: tráfego intenso (heavy traffic), tráfego aéreo (air traffic), tráfego de dados (data traffic). It describes flow rather than a particular crime.
Use tráfego for movement or flow

Use tráfico for trafficking or a trade
Tráfico with i often refers to trafficking, especially an illegal trade in people, drugs, weapons, or protected wildlife. In this use, it names an organized activity rather than ordinary movement on a road.
