Transportation agencies are currently challenged to keep up with culvert infrastructure that is rapidly deteriorating due to lack of adequate maintenance and capital improvement. It is imperative for the transportation agencies to identify and rehabilitate deteriorated culverts prior to their failures. Among several concerns, lack of rational rehabilitation prioritization tools is foremost. Complicating this need further, current practices vary widely across the state departments of transportation (DOTs) which makes it difficult to develop a universal approach for prioritizing failing culverts. This paper presents and demonstrates a failure risk-based culvert prioritization approach that is compliant with the inspection procedures of the South Carolina DOT. The approach presented in this paper is specifically developed for reinforced concrete pipe (RCP) and corrugated metal pipe (CMP) materials because of their wide popularity. Outcomes from a survey of state DOTs informed the development of parametric weightings using the principles of analytical hierarchy process (AHP). Weightings developed for several critical inspection parameters are combined with the corresponding condition assessment scores to determine the failure criticality of culverts, which are subsequently combined with estimated failure consequences to determine failure risk estimates. The prioritization approach is demonstrated using the condition assessment scores of over 5200 culvert structures in South Carolina.

Performance measurement is an evolving practice. All state departments of transportation (DOTs) have used some aspect of performance measurement for analyzing system uses and conditions as part of the engineering and planning disciplines. Yet the business management process and accountability aspects of the performance measurement field have emerged in the transportation industry just in the past decade. State DOTs operate under heightened political pressures, and accountability mandates drive change in performance measurement practices. This paper illuminates important trends that drive the evolution of the field and that need greater attention in research. The emerging purposes and needs for performance measurement and performance management have substantial implications for practitioners and managers. The paper first describes the research purpose and method and presents a generational model for conceptualizing the stages in performance measurement development in transportation agencies. Next, the major pressures that drive performance measurement development are noted, and the most pertinent responses uncovered by this research are summarized. The paper concludes with recommendations for advancing the field and opportunities for further research. This report does not critique specific practices or judge state capabilities. Its intention is to describe emerging trends and needs driving the changing practice of performance measurement at state DOTs by using illustrative examples to help practitioners understand the state of the field and prepare for potential challenges ahead.

As bicycling and walking have become more integrated into transportation agencies’ processes of planning, design, and operations, some state, regional, and local agencies have established nonmotorized data collection programs of varying scopes and with varying methods. The purpose of this study was to identify ways to plan and implement a nonmotorized count program in Virginia, and the scope included reviewing existing U.S. national-level guidance and examples from state departments of transportation (DOTs) other than Virginia’s to determine the most effective ways of implementing such a program. Study tasks included synthesizing the literature to obtain relevant information with regard to nonmotorized travel monitoring programs, practices, and technologies, as well as obtaining information from representatives of three states through interviews of public agency staff and researchers involved in each state’s program. The study found a large volume of recent research on the topic of nonmotorized travel monitoring. The study concluded that the practice of nonmotorized travel monitoring has evolved and expanded in recent years; that many commercially available counting technologies exist and have been evaluated; that the practice of nonmotorized travel monitoring, as with motorized travel monitoring, has several aspects beyond purchase and installation of automatic count equipment; and that several states are developing nonmotorized count programs and have begun putting their data to use. The findings provide a foundational resource for state DOTs that are considering developing state-level counting programs.

Faced with a growing number of work zones, transportation agencies are being challenged to effectively manage the impacts of these zones, alleviate congestion, and maintain the safety of motorists and workers without disrupting project schedules. Coordinating work zones has already been practiced by various state departments of transportation and transportation agencies, yet there are no universal department of transportation policies that address how agencies should coordinate or consolidate projects. In addition, only a few states utilize computer tools specific to regional or corridor-based work zone coordination. State departments of transportation mostly coordinate significant and long-term projects. However, the majority of roadway projects include minor repair, roadway maintenance, bridge maintenance, surveying, and landscape and utility work that require relatively short-term work zones. The Work Zone Coordination Software tool was developed to provide the New Jersey Department of Transportation with an easy-to-use tool to evaluate the feasibility and effectiveness of coordinating short- and long-term work zones and to measure the benefits. This online tool is implemented with a web-based user interface. It integrates all scheduled and active construction projects, identifies conflicts between work zone projects, and estimates the benefits of conflict mitigation. The Work Zone Coordination Software tool works with the New Jersey work zone database by automatically importing data to provide up-to-date information to its users. However, the tool is built on a flexible framework that allows the integration of any work zone database provided that it includes all the required information.

Qfd Method

The Musculoskeletal disorder (MSDs) is skeletal muscle disorders that lead to damage in nerves, muscles, joints and cartilages. The damage is caused by muscle tension and degeneration. From the preliminary research in virgin coconut oil (VCO) processing industry, Central Java, Indonesia, there are potential risk of MSDs for workers. The majority of operators complaining on the right thigh (score 37) and left thigh (score 35). In addition, 50% of operators is work with moderate risk (rapid entire body assessment scores 4-7) and 50% others at a high risk level (rapid entire body assessment scores 8-10). Therefore, improvement is needed to prevent MSDs through work facility design using an integrated quality function deployment (QFD) method. In QFD, there is a concept screening phase to select some product design concept. To determine the priority, the QFD method can be integrated with analytic hierarchy process (AHP) method. The research shows that attributes of work facility needed by user are ergonomic, portable, durable and aesthetic. Concept design B have the highest priority score 0,32 and selected as the final work facility design. The technical specification are made from mahogany wood with an attractive design, red colour combination and developed based on user's anthropometry data.

In order to address challenges in the sustainable development of transportation, economy, and environment, governments along with conventional automobile manufacturers and consumers are extremely interested in the development of the electric vehicle (EV) manufacturing industry and market. However, many manufacturers are worried about entering the EV market because of some of the limitations of EVs and government economic policies. A framework for failure risk-based ranking of EV projects is proposed that applies the Analytic Hierarchy Process (AHP) as a method of ranking. The hierarchy structure of the AHP is created with the risk categories, risk factors, and EV project candidates at different levels of the decision. By specifying the failure risk categories and failure risk factors, the ranking of EV project failure risks and the EV projects are accomplished via the pairwise comparison in the AHP. The results from the ranking provide useful information for planning and decision making. In fact, the results of the proposed method make it possible to specify the EV projects that are feasible to carry out and to compare the various projects at the technical and economic level.

The amount of data being maintained by state departments of transportation (DOTs) and local transportation agencies is increasing steadily. Although data provide opportunities to facilitate decision making at transportation agencies, there are challenges involved in managing large and diverse data. This article provides an assessment of the maturity of three data management practice (stewardship, storage and warehousing, and integration) for 16 transportation data groups based on a survey of 43 DOTs in the United States. The assessment results show that data management practices at the monitoring and operations phases of transportation infrastructure life cycle are likely more mature than those at other phases. Inventory data, in particular, has the most mature data management practices. On the other end, real estate data and travel modeling data have the least mature data management practices. A comparison of the practices indicates that data stewardship is more mature than data integration and storage and warehousing practices.

The operation and maintenance sectors of electric multiple unit (EMU) are considered as game participants to optimize the preventive maintenance (PM) schedule of EMU components. The total cost of a component over a life cycle includes failure risk and maintenance cost. The failure risk of EMU components is assessed quantitatively by using an analytic hierarchy process and scoring and weighting the factors that affect the failure risk of such components. The operation sector expects failure risk to be minimized, whereas the maintenance sector expects maintenance costs to be low, and their interests interfere with each other to some extent. This study establishes a tristage bargaining dynamic game model of the operation sector priority bid and maintenance sector priority bid considering the PM reliability threshold R as the bargaining object. A numerical example demonstrates that the result is more beneficial to the sector that bids first, and the operation priority bid allows the component to maintain a higher reliability level over a life cycle, especially in the latter half of the component life cycle.

Biodiversity Analysis

Because transportation projects have the potential to affect local and regional biodiversity, it is likely that the evaluation of impacts on biodiversity will become an increasingly important issue in the planning process. Transportation Research Board's Task Force on Natural Resources conducted a survey of state transportation agencies in early 1995. Its intention was to determine the current state of biodiversity analysis in the transportation community, the extent to which biodiversity is becoming an emerging issue for state departments of transportation, and how the issue is being managed.
