To optimize available funds in preserving the national transportation infrastructure, the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) mandates that state and local agencies develop and implement various infrastructure management systems. One of these systems is a pavement management system (PMS). To comply with ISTEA, jurisdictions must implement a working PMS in order to continue to qualify for federal funds. Institutional issues that obstruct the implementation of PMS by local agencies are identified and analyzed. For effective implementation and continued use, PMS is viewed as both a new philosophy that must be incorporated into the overall organizational goals of an agency and a support tool for better decision making. Since pavement management is usually only one of several agency functions, the large expenditure of resources associated with PMS implementation is impractical for smaller agencies with limited budgets. This situation has lead to the abandonment of several PMS programs. Through a case study of the San Francisco Bay Area's Metropolitan Transportation Commission, strategies for the effective implementation and continued use of PMS are examined, as is the umbrella role of larger metropolitan planning organizations in successfully implementing PMS at local levels. Competing pavement budget requirements between local agencies are examined within the new context of ISTEA's comprehensive system. Finally, it is suggested that implementing PMS within the broader context of an overall infrastructure management apparatus is a strong incentive for optimizing the complete infrastructure system and achieving ISTEA's goal.

Several local agencies in the San Francisco Bay Area use the Metropolitan Transportation Commission (MTC) pavement management system (PMS) that requires a pavement condition index (PCI) as the primary condition measure. This PCI is based on distress types, severities, and quantities. However, several of these local agencies must also submit present serviceability rating (PSR) data on a sample of their network for use in the Highway Performance Monitoring System (HPMS). Currently, these agencies use a trained rater to determine a subjective PSR value for each HPMS section to report to FHWA and another set of trained raters to inspect the pavement for surface observable distress from which the PCI is calculated. A study was performed to develop mathematical models to relate the PCI used in the MTC PMS to the subjective PSR submitted by local agencies for FHWA’s HPMS reports. Regression equations were developed to predict the PSR values, as defined for HPMS, from Bay Area PCI values and subcomponents of the PCI. These equations have R2 values that show moderate to strong relationships between the HPMS PSR and the MTC PCI. They provide reasonable values at or near the boundaries of the PSR scale. The local agencies using the Bay Area PMS can use these equations to estimate a PSR value from the inspection required for the PMS without inspecting pavement sections a second time.

<p>Emergency logistics is a special part of the logistics system. When emergencies occur, emergency logistics is indispensable. Currently, the current situation of cross-border emergency logistics has many drawbacks. In order to further reduce the losses caused by emergencies, it is necessary to improve the cross-border emergency logistics system, in-depth analysis of the current problems in the four aspects of cross-border logistics management, systems, logistics information, and material distribution in countries along the Belt and Road Initiative, through the establishment of a cross-border emergency logistics coordination mechanism, relevant strategies are established to ensure the effective implementation of emergency logistics.</p>

Pavement Performance Prediction

The progress made over the past three decades in the key elements of pavement management systems was evaluated, and the significant improvements expected over the next 10 years were projected. Eight specific elements of a pavement management system were addressed: functions, data collection and management, pavement performance prediction, economic analysis, priority evaluation, optimization, institutional issues, and information technology. Among the significant improvements expected in pavement management systems in the next decade are improved linkage among, and better access to, databases; systematic updating of pavement performance prediction models by using data from ongoing pavement condition surveys; seamless integration of the multiple management systems of interest to a transportation organization; greater use of geographic information and Global Positioning Systems; increasing use of imaging and scanning and automatic interpretation technologies; and extensive use of formal optimization methods to make the best use of limited resources.

Laws And Regulations

During recent years, the United States has paid increasing attention to controlling and minimizing environmental pollution. One result of this attention is the development of new laws and regulations, enforced by the Environmental Protection Agency (EPA) and by state and local agencies. These new environmental laws and regulations are considerably more stringent than those of past years and they directly impact how shipyards must conduct their operations. This paper discusses these laws and regulations at the national, state (including California, Virginia, and Connecticut), and local levels. With the environmental regulatory background in focus, the paper proceeds to explore the effects of the regulatory trend on one particular segment of the shipbuilding and ship repair industry: floating dry docks. Floating dry docks provide an illuminating example, because of the environmentally sensitive industrial activities carried out on board, such as grit blasting and painting with antifouling paints. The operational norms of floating dry dock pollution control are discussed, starting with present day commercial and Navy facilities, and culminating with the Navy's newest floating dry dock design, the AFDB 10.
