Constructing a fundamental diagram for traffic flow with automated vehicles: Methodology and demonstration

چکیده
Increasingly, commercial vehicles are equipped with automated vehicle (AV) features such as adaptive cruise control systems. The AV feature can automatically the headway between current and preceding in an manner. automatic may lead to significantly different car- following motions compared those of human-driven vehicles, which challenges applicability classic traffic flow theory emerging road AVs. To investigate impacts AVs on flow, this paper proposes a general methodology that combines both empirical experiments theoretical models construct fundamental diagram (FD), i.e., foundation for traffic. demonstrate experiment settings, we collected high-resolution trajectory data multiple one another platoon settings. field results revealed traditional triangular FD structure remains applicable describe characteristics Further, by comparing FDs it was found although shortest setting improve capacity, other settings decrease capacity existing human-driven-vehicle It also affect stability has been studies but first verified data. With these findings, mixed were derived incorporating penetration rates. method proposed paper, including designs, collection approaches, analyses, construction serve methodological studying future uncertain evolving technologies.

Derivation of a Fundamental Diagram for Urban Traffic Flow
Despite the importance of urban traffic flows, there are only a few theoretical approaches to determine fundamental relationships between macroscopic traffic variables such as the traffic density, the utilization, the average velocity, and the travel time. In the past, empirical measurements have primarily been described by fit functions. Here, we derive expected fundamental relationships from ...

This paper further investigates the specification and calibration of FDs. The purpose is to provide a consistent, systematic, and adaptive way to obtain FDs from single-loop detector measurements. In particular, the piecewise linear form is adopted for the FD, because (a) more-complex forms of the FD can be approximated by a piecewise linear form with arbitrarily many pieces, and (b) empirical ...
