Painted Rumble Stripes: Alternatives To Raised Pavement Markers (Rpms), Thomas M. Brennan Jr, Stuart R. Mikey, Darcy M. Bullock

JTRP Posters

This poster highlights research completed by the Joint Transportation Research Program (JTRP) led by Darcy Bullock, Lyles School of Civil Engineering, Purdue University, for JTRP Project SPR-3528, "Alternatives to Raised Pavement Markers (RPMs)." The poster includes photos taken at a construction site on State Road 25 located near Shadeland, Indiana. The top photo demonstrates how the center line corrected a driver when snow covered to avoid oncoming traffic. Photo was taken on US 231 near Country Road 800 in Tippecanoe County.

Managing Risk Perception In Adventure Tourism Activities, Ann O'Connor

Theses

The Adventure Tourism Industry is a customer service industry where product development and presentation is propelled by the clients' needs and desires. The majority of people who participate in adventure tourism activities are novices and have no prior experience or relevant skills. It is this market of 'no skills required' which is the focus of the commercial adventure tourism industry. As there are inherent risks involved in all adventure activities, risk, risk perception and risk management are key skills for the Adventure Activity Provider and Guide. Risk however is multidimensional, made up of physical risk components and subjective risk components. …

Equipment Fragility Due To Shock Response, Christopher Y. Tuan

Department of Civil and Environmental Engineering: Faculty Publications

Because of its simplicity, the shock response spectrum has become widely used as a means of describing the shock responses and fragilities of structures and equipment. This paper focuses on the drawbacks of using the shock response spectrum for defining equipment shock tolerance. A cantilever beam with a tip mass was used to model a hypothetical piece of equipment subjected to strong ground motion such as that caused by an explosion. The exact solution from a detailed modal analysis shows that multiple modes of response were excited. Contributions from higher modes can be more predominant than that from the fundamental …

Naval Aviation Squadron Risk Analysis Predictive Bayesian Network Modeling Using Maintenance Climate Assessment Survey Results, Harry Michael Robinson

Computational Modeling & Simulation Engineering Theses & Dissertations

Associated risks in flying have resulted in injury or death to aircrew and passengers, and damage or destruction of the aircraft and its surroundings. Although the Naval Aviation's flight mishap rate declined over the past 60 years, the proportion of human error causal factors has stayed relatively constant at about 80%. Efforts to reduce human errors have focused attention on understanding the aircrew and maintenance actions occurring in complex systems.

One such tool has been the Naval Aviation squadrons' regular participation in survey questionnaires deigned to measure respondent ratings related to personal judgments or perceptions of organizational climate for meeting …

Analysis Of Factors Affecting Technological Innovativeness In Engineering Enterprises In Tanzania, Emanuel Mjema

Tanzania Journal of Engineering and Technology (TJET)

This paper discusses the technological innovativeness in engineering enterprises in Tanzania and analyses the factors affecting the innovativeness. It starts by analyzing various concepts regarding innovation, then analyzed from documentary review factors affecting innovativeness and then analyzed the innovativeness in Tanzanian enterprises. From the documentary review it was learnt that the following key factors influence technological innovativeness: Existence of innovation management; Existence of market to absorb the products of innovation; Existence of partnership between the universities and the firms; Existence of positive culture and politics towards innovation; The government playing its role to influence innovation; Existence of the right knowledge; …

Optimising The Performance Of Roundabouts In Dar Es Salaam City, David Mfinanga

Tanzania Journal of Engineering and Technology (TJET)

Intersections are one of the major bottlenecks that aggravate congestion in road networks; effective control of which is an important strategy in improving traffic flow. While developing countries have found it hard to adopt sophisticated means of intersection control, they have also not optimised the performance of roundabouts. This paper reviews the performance of roundabouts, which have become increasingly popular in recent years, as simple and low cost forms of intersection control. The performance of three major roundabouts in Dar es Salaam has been analysed and results show that roundabouts can accommodate high traffic volumes without causing excessive delays. The …

Network Interdependency Modeling For Risk Assessment On Built Infrastructure Systems, Vhance V. Valencia

Theses and Dissertations

As modern infrastructures become more interconnected, the decision-making process becomes more difficult because of the increased complexity resulting from infrastructure interdependencies. Simulation and network modeling provide a way to understand system behavior as a result of interdependencies. One area within the asset management literature that is not well covered is infrastructure system decay and risks associated with that decay. This research presents an enhanced version of Haimes' input-output inoperability model (IIM) in the analysis of built infrastructure systems. Previous applications of the IIM characterized infrastructure at the national level utilizing large economic databases. This study develops a three-phased approach that …

An Analysis Of Safety Culture & Safety Training: Comparing The Impact Of Union, Non-Union, And Right To Work Construction Venues, Harry Miller Csp, Tara Hill, Kris Mason, John S. Gaal Edd

Online Journal for Workforce Education and Development

The construction industry is one of the most dangerous sectors of the US economy. As such, the safety attitudes and climate within small (residential) contracting firms may play a role in providing a safe culture and working environment. The intent of this practitioner-based research study is to compare and determine if there is a difference in safety practices—based on documented field inspections and their related original number of violations observed by OSHA—between union residential carpentry contractors in the St. Louis area and:

1) non-union residential carpentry contractors in the St. Louis area;

2) non-union residential carpentry contractors across Missouri; and …

Issue Brief: Saving By Mitigating, University Of Louisville, New England Environmental Finance Center

Sustainable Communities Capacity Building

Natural disasters can cause loss of life, inflict damage to buildings and infrastructure, and have devastating consequences for a community’s economic, social, and environmental well-being. Hazard mitigation means reducing damages from disasters.

Local governments have the responsibility to protect the health, safety, and welfare of their citizens. Proactive mitigation policies and actions help reduce risk and create safer, more disaster-resilient communities. Mitigation is an investment in your community’s future safety, equity, and sustainability.

On The Primitives Of Causality: From The Semantics Of Agonist And Antagonist To Models Of Accident Causation And System Safety, Loïc Brevault, Francesca Favaro, Joseph Saleh

Faculty Publications

Controversial discussions on causality have been present in ancient philosophy since the days of Aristotle. Despite the use of this concept in numerous subjects, there is no consensus on the definition of causality and its possible mathematization. Many authors have analyzed the relation between causes and effects; the predominant school of thought reduces causation to a physical relation (either deterministic or probabilistic) between two events. The distinction between causes and consequences is not always clear and meaningful as different “layers of understanding” may be applied to the notion of causality. From this point of view the cause-effect implication relation can …
