Analyzing the relationships between travel mode indicators and the number of passenger transport fatalities at the city level

Objective: A number of efforts have been conducted on travel behavior and transport fatalities at the neighborhood or street level, and they have identified different factors such as roadway characteristics, personal indicators, and design indicators related to transport safety. However, only a limited number of studies have considered the relationship between travel behavior indicators and the number of transport fatalities at the city level. Therefore, this study explores this relationship and how to fill the mentioned gap in current knowledge.

Method: A generalized linear model (GLM) estimates the relationships between different travel mode indicators (e.g., length of motorway per inhabitants, number of motorcycles per inhabitant, percentage of daily trips on foot and by bicycle, percentage of daily trips by public transport) and the number of passenger transport fatalities. Because this city-level model is developed using data sets from different cities all over the world, the impacts of gross domestic product (GDP) are also included in the model.

Conclusions: Overall, the results imply that the percentage of daily trips by public transport, the percentage of daily trips on foot and by bicycle, and the GDP per inhabitant have negative relationships with the number of passenger transport fatalities, whereas motorway length and the number of motorcycles have positive relationships with the number of passenger transport fatalities.     

The more I want,the less I have left to give: The moderating role of psychological entitlement on the relationship between psychological contract violation,depressive mood states,and citizenship behavior

Research has emphasized the negative effects of organizations' broken promises and failed obligations on employee attitudes and behaviors. However, not all employees respond in the same manner. This paper integrates research on psychological contracts and psychological entitlement to examine how individuals with exceedingly high demands and expectations react to a perceived letdown by the organization. Drawing on conservation of resources theory, we argue that a psychological contract violation is associated with employee depressive mood states, which, in turn, influence the amount of citizenship behavior displayed. We further posit that psychological entitlement moderates the link between contract violation and depressive mood states. Using Hayes' PROCESS macro to assess a moderated mediation model, findings from a multi‐source field study support our predictions. This research contributes to the work on psychological contracts and psychological entitlement on multiple fronts. Suggestions for future research and practical implications for managers are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Drink driving and risky behavior among university students in southwestern Nigeria—Implications for policy development

Background: Drink driving contributes significantly to road traffic injuries. Little is known about the relationship between drink driving and other high-risk behaviors in non-Western countries. The study aimed to assess the relationship between drink driving and other risky behaviors including making phone calls, sending text messages, nonuse of protective gear, and driving against traffic.

Methods: A cross-sectional survey of risky behavior among undergraduates was conducted. A stratified random sampling method was used to identify young undergraduates who had driven a motorized vehicle in the past year. The Alcohol Use Disorder Identification Test (AUDIT) and other tools developed by researchers were used to identify the risky behaviors.

Results: Of 431 respondents, 10.7% had engaged in drink driving in the past 12 months. The most common risky behavior was making phone calls (63.7%), followed by nonuse of helmets (54.7%), driving against traffic (49.2%), nonuse of seat belts (46.8%), and sending text messages (26.1%). Alcohol use was significantly associated with making phone calls (U = 1.148; P < .0001), sending text messages (U = 1.598; P = .021), nonuse of helmets (U = 1.147; P < .0001), driving against traffic (U = 1.234; P < .0001), and nonuse of seat belts (U = 3.233; P = .001). Drink driving was associated with all risky behaviors except nonuse of seat belts (U = 1.842; P = .065).

Conclusion: Alcohol use and drink driving were associated with multiple risky driving behaviors. This provides useful insight for policy development and presents additional challenges for traffic injury prevention.

The current status and future issues in human evacuation from ships

The International Maritime Organization (IMO) developed guidelines in May 1999 for the evacuation analysis of Ro-Ro passenger ships to prevent loss of life in maritime accidents. However, IMO considered these guidelines only as an interim measure and allocated 3 years for their improvement and further development as very limited experience and data were available. In this paper, the requirements of the IMO and current research regarding ship evacuation are reviewed. In addition, applicable evacuation models are presented as well as several experimental methods of obtaining the data of human behavior in regard to listing and the dynamic effect of waves on a ship are evaluated. Recommendations on further issues are discussed at the end.     

PUBLIC PARTICIPATION IN WATER PLANNING: A CRITIQUE OF THEORY,DOCTRINE, AND PRACTICE1

ABSTRACT. Water development planning has virtually since its beginnings over one hundred fifty years ago utilized a variety of devices for involving segments of the public. But a new insistence for increased public participation, particularly at the Federal level, has stimulated re-examination of objectives and methods for relating water planning to citizen interests and preferences. Involved is partly a recommitment to democratic symbols, partly a recognition that segments of society have been overlooked, and partly a reaction to the pressures of confrontation and demonstration. The rhetoric and polemics of participation have often implied a kind of “town-meeting” process of decision, difficult at best in a nation of 200 million. In water planning more emphasis has been placed on listening to citizens, which has meant providing opportunities for influentials to express their views and preferences. A more adequate approach would seem to require identification of all who are significantly affected by plans and proposals (even though they may not perceive then-interest). But gaining greater participation does not make the planning job easier. It may increase tension and conflict; it may require difficult choices; and it can alter existing power relationships and generate changes with considerable consequences for the agency and its programs.     

COMPUTER SIMULATION OF RECREATIONAL BOATING ACTIVITIES1

ABSTRACT This paper is concerned with the portion of harbor improvement planning which identifies the refuge and transient service needs at points along Lake Michigan. The travel behavior model developed to predict this use is sensitive to five criteria: boater characteristics which influence travel behavior; entry rates into the Lake from each access site; site characteristics; weather conditions; and planning parameters. The information provided by this computer model includes: the number of boaters demanding a given access point at a given time; the length of stay at that point; the probability of travel to specific access sites in given amounts of time; and those facilities used during a specified time period. The simulation modelling boat movement consists of two parts; a traffic generation routine and an activity simulation. The former schedules the entry of boats into the Lake from each site and the latter establishes the probabilistic movement of boats on the Lake. This simulation of interport movements and port activities enables the planner to investigate some impacts of alternative small boat harbor development plans.
