Fundamental traffic flow diagramUnmanned aerial vehicleARCGISGeospatial analysisLateral gapLane disciplineA significant difference in the behavior of heterogeneous and undisciplined traffic streams is observed when compared with the conventional traffic flow. Most of the existing traffic flow models are ...
Bicycle has become one of the important commuting travel ways to residents who are living in developing countries including China. Therefore, it's of great theoretical interest and industrial significance to study on the fundamental diagram of bicycle traffic flow. According to the operating characteris...
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 ...
The Macroscopic or Network Fundamental Diagram (NFD) describes the relationship between the network flow and the number of travellers within the network. The shape of the NFD is important for control purposes like perimeter control or routing. However, it is unknown how the network structure influen...

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 ...
we propose a quantitative and consistent theory of the empirical\nfindings based on a phase diagram of congested traffic states, which is\nuniversal for all conventional traffic models having the same instability\ndiagram and a fundamental... D Helbing,I Farkas,D Fasold,... 被引量: 7发表: ...
The Macroscopic Fundamental Diagram(MFD)is the essential attribute of the road network,which can reflect the changing law of traffic state intuitively and accurately.A method of network traffic congestion discrimination was proposed based on macroscopic fundamental diagram and Markov chain model.This metho...
The evolution of the fundamental diagram with changes in maximum platoon length is studied to investigate the impact and magnitude of maximum platoon lengths on the road capacity under different CAV permeabilities. Finally, the study explores the stability and safety of heterogeneous traffic flow ...
The spatio-temporal features of traffic flow are essential to analyze and predict congestion. Our study proposes a data-driven model to predict the traffic congested flow. Firstly, the traffic zone/grid method is used to store the local area roads’ average speed of the vehicles. Second, the ...
