This project presents five tools that were created for a geographical information system to estimate Annual Average Daily Traffic using linear regression. Three of the tools can be used to prepare spatial data for linear regression. One tool can be used to calculate a connectivity importance index for the streets of a city. The main tool can be used to conduct linear regression to estimate Annual Average Daily Traffic. The tools were created for ArcGIS 10 using open-source python scripting.

Forest information collection plays an important role in the process of building modern forestry. This paper proposes a monitoring system-Sensing Forest System, based on the Internet of Things, 3G and 3D GIS, to make up for the shortcomings of traditional monitoring methods. Key issues, such as system architecture, design of wireless multimedia sensor nodes and data transfer process in the network, have been studied and presented, for obtaining real-time comprehensive forestry information, accurately, automatically and remotely, to lay foundations for applications of the Internet of Things in forestry.

Anecdotal and empirical evidence has shown strong associations between the built environment and individuals travel decision. To date, data about individuals travel behavior and the nature of the retail environment have not been linked at the fine-grained level for verifying such relationships. GPS and GIS have revolutionized how we measure and monitor land use and individual travel behavior. Compared with traditional travel survey methods, GPS technologies provide more accurate and detailed information about individuals trips. Based the GPS travel data in the Twin Cities we analyze the impact of individuals interactions with road network structure and the destinations accessibility on individuals destination choice for home-based non-work retail trips. The results reveal that higher accessibility and diversity of services make the destination more attractive. Further, accessibility and diversity of establishments in a walking zone are often highly correlated. A destination reached via a more circuitous or discontinuous route dampens its appeal. In addition, we build an agent-based simulation tool to study retail location choice on a supply chain network consisting of suppliers, retailers, and consumers. The simulation software illustrates that the clustering of retailers can emerge from the balance of distance to suppliers and the distance to consumers. We further applied this tool in the Transportation Geography and Networks course (CE 5180) at the University of Minnesota. Student feedback reveals that it is a useful active learning tool for transportation and urban planning education. The software also has the potential of being extended for an integrated regional transportation-land use forecasting model.

This chapter provides a comprehensive and chronological review of the procedures that were used to identify suitable sites for wetland and stream restoration in the Swan Creek and Tenmile Creek/Ottawa River watersheds within northwest Ohio. It includes an explanation of the datasets that were used to generate aerial photographic base mapping, evaluation of existing conditions within the two watersheds and the development of the GIS predictive model that was utilized to identify potential wetland and stream restoration sites and that were used to select the final 26 sites for the development of conceptual wetland and/or stream restoration plans.

The main service interoperability models (SOA and REST) are currently implemented in the Web with text based technologies (XML, JSON, HTTP), conceived for large grained hypermedia documents. Their extension to the Internet of Things context, involving devices with constrained capabilities and unreliable wireless network protocols, implies using a subset of the features of those technologies and adapting the network and message level protocols. This chapter starts by establishing a layered interoperability framework, from the organizational down to the network protocol levels. Then, it assesses the constraints and limitations of current technologies, establishing goals to solve these problems. Finally, a new interoperability technology is presented, based on a distributed programming language (and its execution platform) that combines platform independence and self-description capabilities, which current data description languages exhibit, with behavior description (not just data), elimination of the need of a separate language for schema or interface description, complete separation of data and metadata (optimizing message transactions) and native support for binary data (eliminating the need for encoding or compression).

Exploring new applications and services for mobile environments has generated considerable excitement among both industries and academics. In this paper we propose a context-aware recommender system that accommodates user's needs with location-dependent multimedia information available in a mobile environment related to an indoor scenario. Specifically, we propose a recommender system for the planning of browsing activities that are based on objects features, users' behaviours and on the current context the state of which is captured by apposite sensor networks. We present the features of such a system and we discuss the proposed approach.

State Departments of Transportation, including the Texas Department of Transportation (TxDOT), have long been moving towards the development and implementation of pavement management systems that would enable monitoring of the performance of their roadways, as well as assist transportation officials with maintenance budget allocation and planning decisions. Various past attempts focused on using the available performance databases as well as state-of-the-art concepts for the development of such systems. The unique characteristics of the state of Texas, the most predominant of which is the vast size of the managed pavement network--79,696 centerline miles of highways including 49,829 bridges--have made some of the decision support models and/or algorithms a challenge to implement. This report presents a new approach to the development of such a decision-support system with its focus on maintenance management for TxDOT. The new system is web-based and provides functional capabilities that allow transportation officials and engineers to make informed decisions regarding their budget planning and budget allocation for pavement maintenance management, fully utilizing available historical data. The developed system has successfully supported some of the TxDOT Districts in the development of their 4-year pavement management plans.

Coordinated data sharing is important for government jurisdictions that overlap the same geographic area. For efficient planning and operations purposes, each jurisdiction should have knowledge of the other organizations' activities that may affect them.

The Western Lake Erie Basin has been targeted as a major contributor of non-point source pollution into Lake Erie largely due to its predominant land use; agriculture. An increased use of GIS among planners in watershed related issues is needed in order to improve their decision-making capabilities to address the overall health of the watershed. An online GIS system had been created for data sharing and management across the Western Lake Erie Basin. The object of this study was to conduct a survey examining the usage of GIS across the Western Lake Erie Basin in order to advance the knowledge of civic leaders, agency administrators, and planners involved in managing the watershed. Survey participants were asked about their current use of GIS, spatial data resources, data distribution, data sharing, data exchange, and future use of GIS. The survey analysis indicated that while the current online GIS system was a good start, there needed to be more training on how to use GIS among the watershed planning community.

The seven Florida Department of Transportation (FDOT) districts are multicounty districts that each interact with a number of county and municipal agencies, including local transit agencies. FDOT District 7 includes the Tampa-St. Petersburg-Clearwater areas, which are among the most populous and complex in the state. District 7 employees regularly need information from the many entities that may interact with transportation planning, design, construction and maintenance. Accessing this information usually nvolves multiple manual steps to locate, acquire, and convert data. To facilitate their work, District 7 has initiated an effort to create an electronic means for intraregional data sharing.
