As transportation systems and technologies evolve, understanding driver performance and behavior is more important than ever. Kittelson LLC has expanded our human factors capabilities to help agencies and clients answer questions like: How do driver interpret new sign designs? How does visibility change with lighting, age, or retroreflective materials? What design choices reduce workload and improve safety? With expertise in driver attention and workload, factors that affect driving performance, driver-vehicle interface design and in-vehicle technologies, and visibility and conspicuity, we help clients translate human-centered research into clear, defensible evidence about how driver perceive, interpret and respond to roadway information. In addition, how to smartphone interfaces and mobile dispatch systems introduce competing attentional demands that degrade timely hazard detection and response?
For attorneys, this mean stronger cases built on:
- Objective, empirical data about what a reasonable driver could attend, see, read, or process
- Reconstruction of driver information load prior to and at the moment of a crash or conflict
- Age, and condition-specific visibility assessments grounded in validated methods
- Expert testimony supported by rigorous, peer-aligned research protocols
Whether evaluating driver attention, sign placement, lighting, retroreflectivity, or driver behavior, our expanded capabilities help legal teams move beyond assumptions and toward measurable, courtroom-ready evidence.
We’re committed to supporting attorneys with the clarity and technical rigor needed to strengthen complex transportation cases.
