Areas of Expertise

Ground Transportation including Vehicles, Pedestrians, and Bicycles

The human element is repeatedly cited as a major cause of highway death and injury. Dunlap applies its human factors expertise to problem identification studies and the development of innovative and effective crash countermeasures. Our team members can either provide expert guidance on the development side, or conduct the necessary research to gather the information you need on an existing system to help you make informed decisions. 

Evaluation

Evaluation should be an inherent part of any program. The Dunlap approach includes problem identification, objective setting, measure development, data collection, assessment of outcomes, and feedback for project improvement. Our evaluations are rigorous, independent, and fully supportive of improved program performance. 

Effects of Alcohol and Drugs

The excessive use of alcohol (and other drugs) has been implicated as a significant causal factor in accidents of all kinds. The Dunlap team has conducted significant landmark research on the effects of alcohol, evaluated devices for measuring alcohol levels, and assessed performance decreases. We are in the process of conducting some of the largest studies of how alcohol and other drugs impact human behavior in the transportation system. We can provide data-driven expertise as to how alcohol and drugs impact individuals in a variety of circumstances and domains. 

Aerospace Systems

Human factors is an important component of safe aerospace operations. Both ground and flight activities can benefit from the smooth integration of humans, equipment, and rules and regulations. The Dunlap team has been in the forefront in applying human factors principles to military and commercial aviation systems and to spaceflight.  

Pupil Transportation Safety and Efficiency

Our team provides consulting services to school systems on the operation of school buses, development of safe routes for walking/bicycling, and for student drop-off/pick-up at the school. We can review existing operations and offer opinions on remedial actions that are needed, or assist with the development of new systems to provide the safest environment possible given the surrounding conditions.

Product Safety

We have had excellent success assisting plaintiffs and defendants during litigation. In addition, we welcome the chance to stop accidents before they happen. While accident avoidance cannot be guaranteed, we pride ourselves in finding potential safety problems and developing appropriate and cost-effective remedial solutions to them. 

Current Projects

Crash Risk of Drugs

A study on the relative risk of crash involvement by drug and alcohol positive drivers involved in fatal and serious injury crashes. Gathering blood samples on a minimum of 2,500 seriously injured drivers treated at three trauma centers and 5,000 control drivers sampled from live traffic at the crash sites of the injured drivers. The study will calculate the relative risk of a driver being severely injured or killed for the drugs tested. 

Older Driver Self-regulation and Exposure

A study of drivers between the ages of 60 and 89 who have a valid driver’s license and drive at least 3 times per week. The purpose of this research is to examine the conditions under which drivers in various age groups choose to drive and how general driving habits vary with age. This is a naturalistic driving study with video and tracking of drivers over a 30-day period. Drivers also completed a pc-based clinical battery and driving evaluation conducted by a certified driving rehabilitation specialist. 

Effects of Speed Education on Speeding Behavior

A project examining the impact of a short online speed education program’s impacts on driver opinions and actual speeding behaviors. The project involves the development and administration of a program to a sample of drivers cited for speeding who will have their opinions and driving behaviors measured before and after training. Drivers will have tracking devices installed in their vehicles to monitor actual speeding. 

EMS/Ambulance Operator Training

 The study is interested in learning if and how agencies providing emergency medical services train and regulate drivers of Type I, II, and III ambulances. This project will document the types of driver training offered, when this training is required, how driving incidents impact driving privileges, initial qualification standards, and other related topics.  

Evaluating Enforcement of Bicycle Safety Laws

A project that is examining motor vehicle and bicyclist crash types to determine which crashes could potentially be impacted by increased law enforcement of motor vehicle driver behaviors. The second phase of the study includes a full evaluation of an enforcement effort focused on the selected behaviors and crash types. 

Pedestrians and DWIs

A project examining whether fatally injured pedestrians with high BACs had prior DWIs as motor vehicle drivers which led to a license suspension/revocation. Data from a number of States will be explored to determine if alcohol positive/negative pedestrians and drivers with high BACs have different driving records.
