Dr. Campbell has over 35 years of experience examining issues related to human factors, driver behavior and performance, and roadway safety. His scientific expertise includes human factors aspects of traffic safety, the capabilities and limitations of road users, and the relative contributions of vehicle, infrastructure, and road user factors to motor vehicle crashes. He has developed guidelines, tools, and training resources to support roadway design, diagnostic assessments, and countermeasure selection. 

Dr. Campbell's on-going research projects for the National Academy of Sciences include development of the 4th Edition of the Human Factors Guidelines (HFG) for Road Systems, the 2nd Edition of the Highway Safety Manual, and the 8th Edition of A Policy on Geometric Design of Highways and Streets (the Green Book).

His expertise also includes the design and evaluation of advanced driver-vehicle interfaces, including head-up displays, collision warning devices, and navigation systems.  Dr. Campbell's on-going research projects for the U.S. Department of Transportation include efforts to address the many challenges for vehicles equipped with driver assistance and driving automation systems, including mental models and driver trust, human-machine interface requirements, and evaluations of driver monitoring systems.
