Traffic engineers are professionals who focus on the design and management of roadways and transportation systems. They analyze traffic patterns, assess safety, and develop solutions to improve the flow of vehicles and pedestrians. Their work often involves using technology and data to create efficient traffic signals, signage, and road layouts. These engineers collaborate with urban planners and government agencies to ensure that transportation systems meet the needs of the community. They also consider factors like public transportation, bicycle lanes, and pedestrian pathways to create a balanced and safe environment for all users of the road.
