Transportation engineering
Wireless communication networks

Background:

Modern transportation systems are complex cyber-physical systems integrating wireless communication.
Connected and automated vehicles necessitate advanced modeling tools to understand communication and traffic interactions.

Purpose of the Study:

To develop a high-fidelity, large-scale, dynamic, and integrated traffic and cellular vehicle-to-everything (C-V2X) modeling tool.
To capture the mutual interactions between communication and transportation systems in real-time.

Main Methods:

Developed a scalable analytical communication model for millisecond-level packet movement.
Coupled communication and traffic simulation models in real-time for a dynamic connected vehicle tool.
Implemented scalable approaches to adjust model coupling frequency based on vehicle density.

Main Results:

Demonstrated a scalable modeling framework on the Los Angeles downtown network during peak hours.
Achieved faster-than-real-time simulation performance on a standard personal computer.
Provided spatiotemporal estimates of packet delivery ratios for the simulated network.

Conclusions:

The novel modeling framework offers a breakthrough for large-scale testing of C-V2X applications.
Enables high-fidelity simulation of integrated traffic and communication dynamics.
Facilitates the development and validation of future connected vehicle technologies.
