Dynamic travel information strategies in advance traveler information systems and their effect on route choices along highways

Delay or travel time information? The impact of advanced traveler information systems on drivers’ behavior before freeway work zones

“…The participants' route choices after limited exposure to different display strategies on text-based VMS and network-based GRIP were measured in the computer task and revealed more route diversions for the GRIP than the VMS. Besides, the results from the stated preference survey showed that respondents preferred delay times on the GRIP but total travel times on VMS (Reinolsmann et al, 2020). These results have not been confirmed yet under (simulated) driving conditions.…”

“…An interactive computer study and stated preference survey was conducted among drivers in Qatar to understand which ATIS design and display factors influence drivers' route choices to a specified destination (Reinolsmann et al, 2020). The participants' route choices after limited exposure to different display strategies on text-based VMS and network-based GRIP were measured in the computer task and revealed more route diversions for the GRIP than the VMS.…”

“…Limitations of this study are that no definition of a poor VMS design was provided and that the design impact on driver's behavior was not specified. Reinolsmann et al (2020) investigated in a computer-based experiment the sensitivity to delay and travel time increases on freeways among drivers in Qatar when traveling on a free weekend or workday. Total travel times, delay times, and regular travel time plus delay were displayed in combination with warning pictograms showing the reason for the delay (e.g., crash, work zone, congestion).…”

“…Furthermore, crash warnings did generally increase the probability of diverting to the alternative route, which was also supported by the results of Ben-Elia and Avineri (2015), who stated that non-recurring incidents such as crashes are considered as being a greater source of uncertainty. Road work-related warnings benefited most from the displayed delay time strategy for the two available routes since the diversion rates were clearly increased as compared to the other time display methods (Reinolsmann et al, 2020). Given that the route choices were not made under realistic driving demands, it was recommended to replicate a work zone congestion incident in a driving simulator to investigate the impact of VMS and GRIP displaying total travel time and delays on drivers' voluntary route choices and driving responses.…”

“…Hayashi et al [33] proposed an information-providing method to express train service situations in central urban areas by combining multiple pictograms, such as sign logo images. Reinolsmanna et al [34] used the pictograms displaying traffic incidences to help drivers select the most appropriate routes along highways.…”
