Interview with Muhammad Fahad- Research Scientist at the University of Wisconsin–Milwaukee: Redefining Traffic Flow and Intelligent Mobility for the United States

Q1. Muhammad Fahad, could you tell us about yourself, your background, your research focus, and what drives your work in autonomous and intelligent transportation systems?

Muhammad Fahad: I’m a researcher dedicated to making transportation safer, smarter, and more efficient through the application of automation and artificial intelligence. My academic foundation began with a master’s degree in mechanical engineering from Tsinghua University, where I published 11 papers that have garnered over 205 citations, with 4 more submitted and under review. As one of the world’s most respected engineering schools, I and currently pursuing my Ph.D. at the University of Wisconsin–Milwaukee.

One of my works focuses on understanding how autonomous and human-driven vehicles interact, and how these interactions shape traffic flow, safety, and energy efficiency. I use deep learning, control theory, and real-world data from roadside sensors and cameras to develop models that predict and optimize driving behavior.

What drives me is purpose. The U.S. is entering an era of automated mobility, and my research helps the nation lead this transition responsibly, balancing innovation with safety, policy, and public benefit.

Q2. Why is your research critical to the United States?

Muhammad Fahad: The U.S. invests billions of dollars in smart infrastructure, connected corridors, and autonomous systems. But the success of these technologies depends on how accurately we can model and manage real-world behavior. My work provides that foundation. It gives U.S. transportation agencies and automakers the scientific tools to predict how automation affects congestion, stability, and safety. This research directly supports national goals for Vision Zero, energy efficiency, and global leadership in intelligent transportation.

Q3. How does your work advance traditional traffic flow theory for the autonomous era?

Muhammad Fahad: Traditional models were built for human drivers. I’ve redefined those frameworks to include automated vehicles and adaptive systems. Using real trajectory data, I’ve shown how automation changes the mathematical relationships between flow, speed, and density, giving planners the ability to forecast how future highways will operate under different levels of automation. It serves as a bridge between classical transportation theory and the modern, AI-driven world.

Q4. What makes mixed-traffic modeling such an urgent challenge today?

Muhammad Fahad: Because this is the phase we’re living in right now. Automated and human-driven vehicles are sharing roads, and their interactions are complex. Human drivers are unpredictable; AVs follow algorithms. My research uses AI to model these dynamics precisely. This helps U.S. cities and states prepare for the next decade, where policies, signals, and designs must simultaneously accommodate both worlds.

Q5. Why is Adaptive Cruise Control (ACC) such a central part of your research?

Muhammad Fahad: ACC is the first widespread automation feature already influencing American highways. It determines how vehicles accelerate, decelerate, and maintain gaps, small behaviors that collectively shape congestion, safety, and fuel consumption. My analysis reveals how these systems behave in real traffic and provides insights manufacturers can use to improve performance. By refining ACC logic, we make every road safer and more efficient.

Q6. What have you learned about how automation affects road capacity and safety?

Muhammad Fahad: Automation reshapes the balance between caution and coordination. At low adoption levels, AVs can create small inefficiencies because they maintain conservative gaps. But once penetration increases, their precision eliminates stop-and-go waves, increasing both capacity and stability. My models pinpoint the exact thresholds at which automation transitions from a limitation to a benefit, providing critical information for national policy and infrastructure investment planning.

Q7. Your research uses vision-based roadside perception. How does that strengthen your results?

Muhammad Fahad: Real-world validation is essential. Using panoramic cameras and RTK-GNSS, I capture precise trajectories of vehicles and pedestrians, then project them into physical coordinates. This enables me to test theoretical models against actual driving behavior. These datasets serve as the foundation for developing standardized U.S. benchmarks in roadside perception, a key component of nationwide safety and performance certification for AV systems.

Q8. How do you approach the balance between mobility and safety in automated driving?

Muhammad Fahad: It’s a delicate trade-off. Shorter headways improve flow but raise risks; longer gaps enhance safety but reduce capacity. My models quantify this balance mathematically and identify optimal control parameters that achieve both. This research helps guide the development of U.S. automation policies that prioritize life safety while maintaining the national economy’s efficient operation.

Q9. Where does artificial intelligence add the most value in your research?

Muhammad Fahad: AI enables the system to learn from behavior rather than rely solely on equations. By training on thousands of real-world trajectories, I can capture nuances of both human and automated driving, including decision timing, reaction delay, and cooperative following. These insights drive the development of the next generation of self-adaptive traffic models, which are capable of anticipating risks and adjusting dynamically. It’s a shift from reactive transportation to predictive mobility.

Q10. What direct impact does your research have on U.S. agencies and industry?

Muhammad Fahad: My frameworks can be implemented in pilot programs and policy studies. They help transportation agencies evaluate mixed-traffic safety, assess automation readiness, and optimize road designs. For the industry, these models provide benchmarks for AV performance, enabling companies to align their products with U.S. traffic conditions and federal standards. Its research is designed to move from the lab to real roads with measurable national benefits.

Q11. How does your work strengthen America’s position in global transportation research?

Muhammad Fahad: Scientific leadership is a defining characteristic of technological leadership. The U.S. can’t afford to follow in mobility innovation; it must lead. My work builds standardized data pipelines, evaluation tools, and analytical frameworks that make the U.S. the reference point for future AV and infrastructure design. It enhances America’s ability to set global safety and performance standards, rather than adapting to others.

Q12. What is your long-term vision for autonomous mobility research?

Closing Remark
