Public law litigation and marine affairs: The boldt decision

Abstract

The management and conservation of the marine environment and its natural resources are increasingly understood to be issues of public policy with consequences for society at large. On a variety of dramatic occasions over the last decades, the federal judiciary has departed from its traditionally passive role in the shaping of social policy. This paper examines a critical marine controversy, the Boldt Decision (U.S. v. Washington 1974), to illustrate and evaluate nontraditional judicial behavior. The first two sections introduce Indian‐United States treaties concerning Pacific Northwest salmon resources, and the unfolding of the Boldt Decision. A third section argues that a “public law”; model of litigation fits the legal events of the Boldt Decision. A fourth section addresses the competence of the Boldt court as it is manifest in judicial organization, analysis, and implementation. A final section comments on the potential for public law litigation elsewhere in the governing of marine affairs.     

Evaluating Boating Safety Risk in Intracoastal Waterways

Growth in the number of recreational vessels that use inland and coastal waterways, coupled with the diversity of boating activities, results in increased boating-related conflicts, accidents, and fatalities. This situation has led to numerous requests from boaters, shorefront property owners, waterfront businesses, and local governments for the imposition and enforcement of boating safety speed zones within Florida's Intracoastal Waterways. A decision-support framework that incorporates Geographic Information Systems (GIS)–based risk assessment was developed to assist the Florida Fish and Wildlife Conservation Commission's Division of Law Enforcement evaluate requests and applications for the establishment of boating safety zones, pursuant to the Florida Administrative Code Rule 68-D-23.105 “Criteria for Approval of Regulatory Markers.” The risk assessment uses geospatial data compiled from multiple government agencies, survey data from subject matter experts, and public input from participatory workshops. Relevant spatial data includes waterway features and marine infrastructure from field surveys, vessel traffic patterns observed and mapped from aerial reconnaissance, and indicators of boater behaviors extracted from accident and citation reports. The outcome is a characterization of waterway segments according to perceived risk to boating safety. The application was tested in two Florida counties and it helped guide the establishment of new, and the revision of existing, boating regulatory zones within their Intracoastal Waterways. The application design is such that it is adaptable to waterways beyond those in Florida.

Automated short headway urban transportation systems were viewed in the early Seventies as a possible means of effecting radical change in the type of transit service available in cities. However, interest has declined and government‐sponsored efforts in this area have ceased. The decline in interest was accompanied by much debate among the advocates of the various forms of transit. However, it does not appear to reflect the potential merits and limitations of short headway systems as disclosed by analysis.

This paper provides a basis for comparing short headway systems of citywide scale with conventional transit means.

The limitations inherent in rapid rail installations are reviewed and contrasted with the performance of short headway systems. Illustrative, large‐scale guideway configurations for systems operating in the three‐second headway range are defined and levels of service are deduced using simplified heuristic methods. A basis is provided for specification and analysis of systems conforming to realistic spatial and passenger‐movement constraints.

It is concluded that automated transit systems operating in the three‐second headway range remain viable candidates for large‐scale installations.     

Defining and measuring service availability for complex transportation networks

Service Availability of a transportation system is a measure of a performance that has been generally defined according to the reliability and maintainability terms of mean-time-before-failure and mean-time-to-restore, as borrowed from the aerospace/defense industry. While such definitions correctly describe the availability of a system and its equipment to function they do not directly measure the percent of designed and scheduled service available for passenger use. For the more complex transportation systems having multiple tracks and routes, fleets of vehicles, more than two stations and more than one mode of service there are needs for definitions that account for isolated failures that partially interrupt or delay service. Successful definitions of service availability have been based on data that is easily and directly entered in the operating log or automatically collected by Automatic Train Supervision (ATS) system and reports generated by software. The following paper first defines measures of service availability in current use and analyzes exact and approximation methods for data collection and computation. Second, the paper postulates and explores classical and new definitions of service availability applicable for complex networks such as Personal Rapid Transit (PRT). Insight is provided for choosing a suitable definition based on the type of transportation network.     

雾封层沥青材料和添加剂的分析与评价

路面再生性的雾封层能减少和预防沥青路面的老化,从而可以减少路面的开裂和松散,使得路面更好更耐久。雾封层的作用是在原有的沥青路面上罩面,起到保护和再生的作用,同时雾封层也可降低水和空气的渗透性。在某种程度上说,渗透性的降低,可以改善路面的防水性能,并且使得粘结剂氧化引起的老化敏感性减少。     

Application of Elementary Neural Networks and Preview Sensors for Representing Driver Steering Control Behaviour

This paper demonstrates the use of elementary neural networks for modelling and representing driver steering behaviour in path regulation control tasks. Areas of application include uses by vehicle simulation experts who need to model and represent specific instances of driver steering control behaviour, potential on-board vehicle technologies aimed at representing and tracking driver steering control behaviour over time, and use by human factors specialists interested in representing or classifying specific families of driver steering behaviour. Example applications are shown for data obtained from a driver/vehicle numerical simulation, a basic driving simulator, and an experimental on-road test vehicle equipped with a camera and sensor processing system.
