Regional Data Archiving and Management for Northeast Illinois

This project studies the feasibility and implementation options for establishing a regional data archiving system to help monitor and manage traffic operations and planning for the northeastern Illinois region. It aims to provide a clear guidance to the regional transportation agencies, from both technical and business perspectives, about building such a comprehensive transportation information system. Several implementation alternatives are identified and analyzed. This research is carried out in three phases. In the first phase, existing documents related to ITS deployments in the broader Chicago area are summarized, and a thorough review is conducted of similar systems across the country. Various stakeholders are interviewed to collect information on all data elements that they store, including the format, system, and granularity. Their perception of a data archive system, such as potential benefits and costs, is also surveyed. In the second phase, a conceptual design of the database is developed. This conceptual design includes system architecture, functional modules, user interfaces, and examples of usage. In the last phase, the possible business models for the archive system to sustain itself are reviewed. We estimate initial capital and recurring operational/maintenance costs for the system based on realistic information on the hardware, software, labor, and resource requirements. We also identify possible revenue opportunities. A few implementation options for the archive system are summarized in this report; namely: 1. System hosted by a partnering agency 2. System contracted to a university 3. System contracted to a national laboratory 4. System outsourced to a service provider The costs, advantages and disadvantages for each of these recommended options are also provided.ICT-R27-22published or submitted for publicationis peer reviewe

ADMINISTRATIVE RESILIENCE: EVALUATING THE ADAPTIVE CAPACITY OF ADMINISTRATIVE SYSTEMS THAT OPERATE IN DYNAMIC AND UNCERTAIN CONDITIONS

An administrative system's capacity to take effective action can be undermined by the uncertain and rapidly changing conditions that are often generated by disruptive events. Resilience has been identified as the most practical approach to overcoming this administrative problem. Resilience has multiple definitions, one of which is "[t]he capacity of a system, community or society potentially exposed to hazards to adapt, by resisting or changing in order to reach and maintain an acceptable level of functioning and structure. This is determined by the degree to which the social system is capable of organizing itself to increase this capacity for learning from past disasters for better future protection and to improve risk reduction measures" (International Strategy for Disaster Reduction 2005, p. 4). This study argues that, in contrast to conventional administrative systems, resilient administrative systems have the capacity to successfully respond to disruptive events because they possess the organizational stability to maintain the effectiveness of the community in which it operates and the organizational flexibility needed to adapt to uncertain and rapidly changing conditions.This study advances a framework for administrative resilience, which can be used to evaluate the resilience of administrative systems. Through the use of a nested case study that employed a mixed-methods design, the framework was used to investigate the administrative response system that operated in Indonesia after the Great Sumatran Earthquake and Tsunami of 26 December 2004. The study generated a number of findings. First, the system was a system of sub-systems, and the organizations that operated in the domestic sub-system possessed extremely low levels of resilience. The consequence was that the domestic sub-system could not formulate an effective response to the constraints present in the post-tsunami environment. Second, it was the inclusion of the organizations in the international sub-system, which brought with them high levels of resources, technology and experience, as well as the interactions exchanged between international and domestic organizations, which improved the resilience of the overall administrative system. These findings indicate that policy makers can promote the development of administrative resilience through the development and implementation of sociotechnical infrastructures that facilitate administrative action

Towards a National 3D Mapping Product for Great Britain

Knowing where something happens and where people are located can be critically important to understand issues ranging from climate change to road accidents, crime, schooling, transport and much more. To analyse these spatial problems, two-dimensional representations of the world, such as paper or digital maps, have traditionally been used. Geographic information systems (GIS) are the tools that enable capture, modelling, storage, retrieval, sharing, manipulation, analysis, and presentation of geographically referenced data. Three-dimensional geographic information (3D GI) is data that can represent real-world features as objects in 3D space. 3D GI offers additional functionality not possible in 2D, including analysing and querying volume, visibility, surface and sub-surface, and shadowing. This thesis contributes to the understanding of user requirements and other data related considerations in the production of 3D geographic information at a national level. The study promotes Ordnance Survey’s efforts in developing a 3D geographic product through: (1) identifying potential applications; (2) analysing existing 3D city modelling approaches; (3) eliciting and formalising user requirements; (4) developing metrics to describe the usefulness of 3D data and; (5) evaluating the commerciality of 3D GI. A review of current applications of 3D showed that visualisation dominated as the main use, allowing for better communication, and supporting decision-making processes. Reflecting this, an examination of existing 3D city models showed that, despite the varying modelling approaches, there was a general focus towards accurate and realistic geometric representation of the urban environment. Web-based questionnaires and semi-structured interviews revealed that while some applications (e.g. subsurface, photovoltaics, air and noise quality) lead the field with a high adoption of 3D, others were laggards due to organisational inertia (e.g. insurance, facilities management). Individuals expressed positive views on the use of 3D, but still struggled to justify the value and business case. Simple building geometry coupled with non-building thematic classes was perceived to be most useful by users. Several metrics were developed to quantify and compare the characteristics of thirty-three 3D datasets. Results showed that geometry-based metrics such as minimum feature length or Euler characteristic can be used to provide additional information as part of fitness-for-purpose evaluations. The metrics can also contribute to quality control during data production. An investigation into the commercial opportunities explored the economic value of 3D, the market size of 3D data in Great Britain, as well as proposed a number of opportunities within the wider business context of Ordnance Survey
