Abstract
In this paper, the impacts of rain on the dynamics of network traffic flow are investigated empirically. The macroscopic fundamental diagram approach is used to obtain the dynamics of network traffic flow. The traffic data from single detectors and the whole network are classified into different categories according to the rainfall intensity. The Van Aerde traffic stream model is used to study the dynamic of traffic flow by calibrating the three key parameters, i.e., free flow speed, speed-at-capacity, and capacity. The calibrated results show that the macroscopic fundamental diagram performs more steady behavior than link fundamental diagram.
