Traffic flow research focuses on understanding and improving the movement of vehicles on roadways. This area of study typically involves analyzing the interactions between different vehicles, road infrastructure, and traffic control systems to optimize traffic flow, reduce congestion, and improve safety. Researchers in this field may use a variety of methods such as data collection, modeling, simulation, and statistical analysis to investigate traffic patterns and develop strategies for more efficient and sustainable transportation systems. Ultimately, the goal of traffic flow research is to enhance the overall functioning of road networks and improve the quality of transportation for drivers and pedestrians.
