Evaluation of a fleet safety management information system

Despite recent interest in work related road safety, relatively little research has been conducted to examine the effects of institutional factors on fleet safety. This paper conceptualized an evaluation framework and utilized it to assess fleet coordinators' attitudes toward and the usage of a fleet safety management system. First, focus group interviews revealed that monitoring fleet safety was not considered an important task within the government agencies participating in the research. Second, similar results were obtained in a survey of the fleet coordinators, which showed that most fleet coordinators were not utilising the full diagnostic capabilities of the management information system. In particular, fleet coordinators reported significantly higher competence, usage and importance on the coordination of fleet vehicle efficiency than on the coordination of fleet safety. These results were supported by the finding that fleet coordinators were required to report more on fleet efficiency than on fleet safety.     

Development of pictograms for dynamic traffic control systems in South Korea

This study developed a set of pictograms for lane control systems, to provide additional information to drivers on weather and traffic incidents. The results suggest that in the design of traffic signs, it is important to consider local context and not simply adopt standards and practices that are developed elsewhere. The differences in the social and cultural environments may affect the ease of reading and comprehension by local drivers. However, the study also showed that not all locally developed signs were rated higher for their ease of reading than others… Since some design characteristics are more salient, whereas others tend to be more dependent on the local context, it is important to conduct simple experiments and exploratory research to find the optimal designs to be used.

St Ursula sails again

The commonest version of the legend of St Ursula tells how she was betrothed to a prince but obtained a 3-year moratorium because she wished to remain a virgin [1]. She spent this time cruising with 11 noble companions, each of whom occupied a ship with 1000 more. After visiting Cologne and Basle and making a pilgrimage to Rome they were all massacred by Huns for their Christianity, Ursula having refused to marry the chief. Variations on this legent include providing her with a Cornish origin and saying that she sailed to Brittany with 11 000 maidens. Whatever her origin and whatever happened to her, it is now thought that the remarkable number of her companions may have stemmed from a medieval copyist's error. This involved expanding the abbreviation 'XI MV' into '11 000 virgins' when it should have read '11 virgin-martyrs'. Whilst there is no real evidence for any of the story (her cult was suppressed by the Roman Catholic authorities in the reforms of 1969) it may be contended that morals may be drawn from it.

Personal space,evasive movement and pedestrian level of service

This study proposed a behavioral theory‐based approach to better assess pedestrian levels of service for sidewalks, using the concepts of personal space and pedestrian evasive movements. Data from pedestrian interviews and video recordings at 28 commercial, residential, and leisure locations were used to analyze the effects of pedestrian movements on pedestrian perceived levels of service. With these results, a new measure of pedestrian level of service was developed. With the use of a separate validation sample, the revised levels of service obtained were found to be more consistent with the pedestrian perceived levels than the levels prescribed by the Korean Highway Capacity Manual. Hence, this research recommended the use of the revised measures for pedestrian level of service in the design and evaluation of pedestrian facilities. We also found that pedestrian evasive movements on sidewalks could better explain pedestrians' perception of the levels of service for a given facility. Moreover, pedestrian evasive movements were found to be sensitive to the width of the sidewalk and pedestrian volume. Copyright © 2013 John Wiley & Sons, Ltd.     

Collecting longitudinal data from freight operators: survey design and implementation ideas and challenges

Freight transport research has generally been limited by a lack of data of the breadth and quality available for passenger transport, particularly in terms of behavioural data. This paper discusses the survey design and implementation of a survey intended to collect longitudinal behavioural data on the responses of freight transport firms to environmental policies. The design of the survey is centred around a hypothetical scenario where respondents are asked how they would complete a given freight task within common constraints. One of the key components of the survey design is a dynamic component intended to simulate the changing business environment. The paper illustrates the many challenges in getting complex freight related surveys in the field.
