Key Findings: Intelligent Level Crossing

Analysis of vehicle performance measures indicated that, when a train was present, participants exhibited more gradual speed reductions and stopped earlier at the Intelligent Level Crossing compared with the existing standard (see Figure 9.2b). When no train was present, however, participants showed minimal slowing and adopted higher approach speeds than at the existing standard crossing.

The Intelligent Level Crossing was ranked equal first in terms of preference and received the highest number of first preference rankings (see Table 9.1). It also achieved the highest usability score (M = 79.6, SD = 18.9), but this was not rated significantly higher than the existing standard (M = 78.7, SD = 16.2). Subjective workload ratings were not significantly different when comparing the Intelligent Level Crossing and existing standard.

Verbal protocol analyses revealed that the Intelligent Level Crossing alerted participants to the presence of a train much earlier than other designs; the concept ‘train’ reached prominence when participants were up to 250 m from the crossing, whereas for all other designs, the train concept did not emerge until within 50 m of the tracks. Participants generally described the Intelligent Level Crossing in favourable terms. They found it easy to use and liked the clear visual and auditory warnings, including the train icon on the in-vehicle display. Perceived negatives of the system included its potential for driver distraction and concerns about the reliability of the technology.

Intelligent Level Crossing
The Intelligent Level Crossing concept is based around the use of new and emerging intelligent transport systems (ITS) technologies to better optimise the functioning of the transport system by improving communication and coordination between road and rail systems. It provides decision support systems...

Key Findings: Community Courtyard Crossing
Analysis of vehicle performance measures indicated that, compared with the existing standard, participants adopted slower travel speeds on approach to the Community Courtyard crossing when no train was present (see Figure 9.2c). This presumably reflects that this crossing incorporated a regulatory speed...

Key Findings: Comprehensive Risk Control Crossing
Analysis of vehicle performance measures revealed that speed profiles when a train was present were broadly similar on approach to the Comprehensive Risk Control Crossing compared with the existing standard (see Figure 9.2a). However, when no train was present, drivers reduced their speed noticeably...

Key Findings: Ecological Interface Design Crossing
Analysis of travel speeds on approach to the Ecological Interface Design crossing revealed different patterns for the train-present and train-absent conditions. When a train was present, drivers showed large speed reductions at the Ecological Interface Design crossing, with approach speeds being slower...

Main Hypotheses Tests of association between one's asset selection decisions and their regulatory focus did not provide any signiﬁcant results (H1). Neither the self-report nor the eye tracker measure yielded signiﬁcant results in this aspect. As such, H1 is unsup- ported, and it is concluded...
