We derived a shifted Gamma traffic count distribution to describe the randomness of traffic flow caused by the uncertainty of drivers’ gap selection, and then derived the fundamental diagram (FD) based on the count distribution. We found out that the uncertainty of drivers’ gap selection ...
Fig. 6. Macroscopic fundamental diagram of mixed LHD and RHD vehicle traffic flow. a illustrates the flow- density relationships for the left, middle, and right lanes under different RHD vehicle penetration rates, with colors indicating the RHD penetration of the data points. b shows the ...
The transition between traffic states and the relationship of traffic parameters are critical to the causality of traffic conflicts. We aim to analyze traffic flow at various levels, such as Levels of Service (LOS), three-phase theory, and the fundamental diagram, to establish a connection ...

This paper aims to analyze the threshold of saturated flow of each lane in an eight-lane expressway merging area under different situations. The concept of saturated is defined firstly and the three-dimensional fundamental diagram which determines the flow, speed, and density thresholds for each lan...

Traffic congestion in the adjacent region between the highway and urban expressway is becoming more and more serious. This paper proposes a traffic speed forecast method based on the Macroscopic Fundamental Diagram (MFD) and Gated Recurrent Unit (GRU) model to provide the necessary traffic guidance...
And the transitions of free flow traffic to congested traffic and the transitions of other way around are different. Hence, the fundamental diagram of individual detectors has significantly impact on the hysteresis phenomena of MFD. It is worthwhile to study the key detectors when the hysteresis of...
