Diamond Future Technology Pc 034 Driver
the highway driving simulator allowed researchers to determine which signal timing strategies help and hinder drivers’ ability to avoid the red signal. for example, they found that the simulated drivers were generally aware of which type of signal (i.e.
after constructing and operating a driving simulator model of the kansas city interchange design, fhwa found the design to be safe, efficient, and effective, and concluded that it could be used to evaluate a significant number of other ddi designs. the fhwa human centered systems team and modot agreed that ddis would be potentially safer and less disruptive than conventional diamond interchanges. fhwa concluded that the design had the potential to reduce vehicle crashes and to improve safety and efficiency. the project is currently in the process of assessing the design and evaluating the operation of the kansas city ddi.
in addition to evaluating the safety of a ddi, fhwa was interested in determining how drivers reacted to, and performed in, a ddi environment. driving simulators are tools that are increasingly being used for evaluating human performance in new systems. fhwa’s research technologies center has developed a model of human-vehicle interaction for the purpose of evaluating new transportation systems. it is a five-variable, analog, human-vehicle simulator that has been calibrated to replicate vehicle and driver behavior in an actual highway setting. it consists of a fully controlled instrumented vehicle that is driven by a trained operator. the system can be used to evaluate single driver performance in a variety of road conditions as well as to assess the performance of drivers operating in different highway environments. after evaluation of the kansas city ddi, the driving simulator model of the design was calibrated to replicate a high-speed urban intersection, and drivers were evaluated to determine how they reacted to the design.
