One of the major evaluation goals of the TravTek operational test was to assess the safety impact of the TravTek system as implemented in Orlando, Florida during the 1-year deployment phase. Also, the results of the TravTek operational test, with respect to safety, were to be used to estimate the potential safety impact of a TravTek-like system under levels of high market penetration. The TravTek study entailed the collection of multiple safety-related measures across five different empirical studies. The empirical studies included two field studies with renters and local drivers that used the vehicles under normal driving conditions. In addition, three experimental field studies were conducted that included a camera car vehicle which was used to collect detailed driver performance and behavior data. Converging evidence from these empirical studies showed that the TravTek in-vehicle system did not degrade driver safety. The simplified Turn-by-Turn display was shown to lead to safest performance. Also, the Voice display of route guidance information was shown to enhance the safety of the complex Route Map display. As part of conducting a trade-off analyses between safety benefits and safety costs, safety related data from the five empirical studies were fused and used as input to the INTEGRATION model. The INTEGRATION model was used to project the potential safety benefits and costs associated with a TravTek system under high levels of market penetration.
