SUMMARY
The discussion centers on the justification for focusing on road segments rather than entire road networks in traffic forecasting models. The participant aims to test the effectiveness of forecasting algorithms, such as ARIMA and Kalman Filtering, to predict traffic flow under free-flowing conditions. Key insights include the need for precise definitions of traffic flow metrics, such as vehicles per time unit, and the importance of using real-world data or simulations for analysis. The conversation highlights the complexity of network analysis and suggests that studying segments may provide clearer insights into traffic dynamics.
