• Optimal Method for Traffic Accident Case Retrieval and Evaluation
  Abstract: An optimal method for traffic accident case retrieval has been proposed to improve accuracy of case retrieval. This method aims to assist users in decision-making in real-time under traffic accident conditions. And a new evaluation index called matching degree, as supplement of case similarity, is proposed for assessing the retrieved case set comprehensively. Different from previous studies, the presented optimal method and evaluation index have the following four critical features: (1) proposing an information entropy method to evaluate dispersion of traffic accident data and determining the weight value of each traffic accident case feature objectively; and (2) establishing a traffic accident case retrieval base which contains several sub-case bases, and that puts a solid foundation for equalizing case retrieval; then (3) proposing a global similarity model of traffic accident cases and two equations for calculating local similarity of numerical traffic data and categorical traffic data; and (4) presenting a new evaluation index called matching degree firstly, make up deficiency of the original evaluation index. This study develops a prototype system for traffic accident case retrieval experiments. Dozens of case retrieval experiments have demonstrated the promise of this optimal case retrieval method and evaluation method for traffic accident management in real-time.

• Decision Support System for Smart Growth Innovation in Urban Midwest: GIS Connection Between Brownfield Site Redevelopment and Transportation
  Abstract: This paper documents the design and development of a prototype web-based data distribution system for brownfield site redevelopment in the urban Midwest. The system is designed to support smart growth initiatives through the application of innovative technology for economic redevelopment and sustainable utilization of brownfield sites in Toledo, Ohio. Many Midwestern cities have experienced industrial decline that has led to a preponderance of brownfield sites, particularly in poorer urban core areas. Brownfield sites are typically situated along existing and often deteriorating infrastructure. Greater efficiency in economic development can be gained by linking transportation infrastructure resources with brownfield remediation. In addition, communities gain countless health, safety, environmental and revenue benefits through the identification and remediation of brownfield sites. A lack of data resources is one major barrier to redevelopment of these sites. The system developed here seeks to reduce that barrier by providing a user interface and information delivery system to support the identification and reuse of brownfield sites for policy and decision-makers; this methodology and design can be replicated for use in other regions to further promote smart growth. Detailed here is the development and implementation of an interactive web-based geographic information system (GIS) designed as a user-centered decision support tool to augment policymakers’ and stakeholders’ site selection and infrastructure capital investment decisions in support of brownfield remediation and development. This system thus provides not only a comprehensive data delivery tool and decision support system but also serves as a template for application in other urban regions.

• Development of Connectivity-Based Underground Fiber-Optic NetworkInventory Systems
  Abstract: Major State Departments of Transportation such as the New Jersey Department of Transportation (NJDOT) operate and maintain networks of thousands of miles of conduits, many carrying fiber optic cables that are vital to State communication systems. These conduits are located alongside or across highways and frequently must be located and marked to avoid damage from digging or boring resulting from construction. The existing inventory system consisted of sections of pipelines of varying length with differing lengths and sometimes unknown or changing diameters and materials. In order to facilitate the location of fiber optic facilities by operations personnel and enable access to junction boxes and conduits, a computerized connectivity-based inventory system for fiber optic segments and nodes (junction boxes) was developed in a first phase. The system enabled the transition from a flat incomplete and inaccurate system of facility identification to a comprehensive hierarchical system of facility cataloguing. An expansion of the system to include multiple inner layers within pipes and junction boxes, such as Conduits and Cables enabled the definition of a Routing entity, an essential component of a comprehensive fiber optic connectivity-based system. Key to the system design is the definition of the multi-layered hierarchical relationships between various levels of facility definition. The ability to “drill-down” from an external layer to an inner component and to establish multi-directional facility contiguity enables the progressive improvement of data quality and the establishment of a reliable connectivity model between facilities. This extended prototype enables the successful transition from a system based on section records to a more connectivity-based hierarchical asset management model of fiber optic underground facilities, with significant savings in operational costs and reliability of the field investigative work.
