It is shown that the branch of the empirical fundamental diagram for congested traffic strongly depends both on the type of the congested pattern at a freeway bottleneck and on the freeway location where the fundamental diagram is measured. Since the type of the pattern at the same bottleneck can depend on traffic demand, a qualitative form of the empirical fundamental diagram can strong depend on traffic demand also. At freeway locations where the average speed in synchronized flow is higher…

In this paper, traffic features of urban ring road are investigated based on empirical data of Beijing 2nd Ring Road. According to the concept of "synchronized flow" as well as the stability and
A Macroscopic Model of Heterogeneous Traffic Flow Based on the Safety Potential Field Theory
TLDR
A novel macroscopic model of the heterogeneous traffic flow under a partly connected and automated environment based on the safety potential field (SPF) theory is developed and indicates that introducing the CAVs into the pure traffic flow of HVs may slightly have a negligible impact on road capacity, but the impact increases significantly as theCAVs penetration rate increased.
Mathematical Models for 3-Phase Traffic Flow Theory
TLDR
The Kerner's 3-phase traffic flow theory, which states that the flow of vehicular traffic occur in three phases i.e. free flow, synchronized flow and wide moving jam phases, is outlined.
Stochastic Modeling and Simulation of Traffic Flow: Asymmetric Single Exclusion Process with Arrhenius look-ahead dynamics
TLDR
Based on scaling and limit arguments, a macroscopic description is obtained of this microscopic dynamics formulation which up to leading term of the expansions takes the form of integrodifferential Burgers or higher-order dispersive partial differential equations.
Automatic Calibration of Freeway Models with Model-Based Sensor Fault Detection
This dissertation presents system identification, fault detection and fault handling methodologies for automatically building calibrated models of freeway traffic flow. Using these methodologies,
Approximation Strategies for Routing in Stochastic Dynamic Networks
TLDR
A new class of Monte-Carlo route planning algorithms that optimize the route using a sample of multiple traffic-state trajectories are presented and it is shown that these methods are able to outperform Monte- carlo methods based on greedy policy look-aheads applied most frequently to solve the stochastic decision problems.
Machine learning solutions for transportation networks
TLDR
A generative probabilistic graphical model to describe multivariate continuous densities such as observed traffic patterns and a dynamic Bayesian network framework that learns and rectifies systematic biases varying from site to site, leading to improved supervised detector performance with little need for manually tagged data.

Congested Traffic Flow: Observations and Theory
Recent and some new results of observations of traffic flow dynamics in congested conditions are considered. On the basis of these results, hypotheses about properties of congested flow are proposed
Empirical Features of Congested Patterns at Highway Bottlenecks
TLDR
It was found that the most frequently observed congested pattern is the general pattern (GP), in GP synchronized flow occurs upstream of a bottleneck and wide moving jams spontaneously emerge in that synchronized flow.
Traffic Flow Fundamentals
TLDR
The remaining portion of the book, Chapters 8 through 13, is devoted to analytical techniques involving the total traffic flow situation; chapter subjects are, respectively, demand-supply analysis, capacity analysis, traffic stream models, shock wave analysis, queueing analysis, and computer simulation models.

TLDR
Experimental investigations of a complexity in traffic flow show that this complexity is linked to space-time transitions between 3 qualitative different types of traffic: 'free' traffic flow, 'synchronized' Traffic jams, and traffic jams.
EXPERIMENTAL FEATURES OF SELF-ORGANIZATION IN TRAFFIC FLOW
Features of the ``stop-and-go'' phenomenon are found. First, the local phase transition ``free flow $\ensuremath{\rightarrow}$ synchronized flow'' is realized. Then the ``pinch effect'' in
