      <title>Visualizing Metra Design Intent Manual</title>
      <link>https://trid.trb.org/View/839940</link>
      <description><![CDATA[Planners and decision-makers in large organizations require access to different types of data and information, typically collected for different purposes by several departments over a period of time. Some of this data is scale-dependent, while other pieces of data and information are scale-independent and therefore likely to be useful in different decision-making contexts. In the case of Metra, Chicago’s regional commuter rail system, decision-makers in different departments (planning, engineering, operations, and marketing) all require information about Metra stations, station yards, data about location and quality of infrastructure such as rail lines, land use patterns, and ridership profiles, though not all information is relevant to each department’s needs. Disseminating information that is meaningful to different users requires that careful attention be paid to data organization and display so that the user can assemble and analyze data most appropriate to their immediate decision-making needs. Researchers are working collaboratively with Metra to develop a prototype information dissemination application that is adaptable to the needs of different departments within the agency. The interactive interface includes text and icon-based navigation. A geographic, scalable base map with embedded links allows the user to navigate to visual, quantitative, or text data that appear on separate pop-up windows. The changing scale (geographic boundary) of the base map allows the user to visualize and access data that is appropriate to that scale. This Manual is meant to be used as a guide to adding content to the Visualizing Metra prototype. The manual will show each section of the prototype and explain its function, features and content rationale.]]></description>

      <title>Paint-The-Region and Long-Range Regional Transportation/Land Use Planning: A Visualization Experience of Northeastern Illinois Planning Commission</title>
      <link>https://trid.trb.org/View/839909</link>
      <description><![CDATA[Northeastern Illinois, with 272 municipalities, more than 1,200 units of government, and 8 million people, requires effective and extensive collaboration on its regional planning process. In 2001, Northeastern Illinois Planning Commission (NIPC) initiated Common Ground, as a Blue Print for Regional Action to address a new standard for public planning. In 2005, this comprehensive planning effort led to the 2040 Regional Framework Plan that provides a set of guidelines for an interactive public planning process aided by the application of state-of-art technology. This paper describes the procedure that was developed to support the visualization of alternative feature in the public participation process. Utilizing internet based customized GIS software, participants are able to “paint the region” on the screen presenting their own desired future in terms of the region’s transportation, land use and the environment. User-friendly multiple digital layers of the existing infrastructure are provided to the participants to enable them to make choices and understand the full complexity of the region’s systems. The painted features are further explained and supported by both general statistics on quantifiable decisions made by each workshop group through innovative keypad technology, and the comprehensive synthesizing process done back at the agency. The final synthesized regional transportation and land use map (in the form of centers, corridors and green areas) is referred to as the Common Ground scenario. Compared with the traditional forecast scenario generated by population forecast and transportation modeling, the Common Ground scenario fills the gap between the qualitative public inputs and rigid transportation planning models through interactive visualization technology, where the geo-database is used as a bridging tool.]]></description>

      <title>Simulation and Rapid Prototyping to Support the Deployment of
Advanced Crash Avoidance Systems</title>
      <link>https://trid.trb.org/View/839938</link>
      <description><![CDATA[U.S. Highway 191 in southwestern Montana has been identified as the location of a number of accident clusters. The accident rate is not significantly greater than that for similar highways with similar traffic densities but the accidents that do happen tend to receive great visibility. Because of the roadway geometry and the lack of practical alternative routes, crashes and incidents in this area have a disproportionate impact on transportation in this heavily traveled corridor. A rapid prototyping approach is being used in the driving simulation laboratory at the Western Transportation Institute (WTI) to simulate approximately 22 miles of U.S. 191 between the Big Sky Resort community and the northern mouth of the Gallatin Canyon. The simulations are used to help the Montana Department of Transportation (MDT) develop and refine safety countermeasures for that roadway. Custom roadway tiles for the simulation were designed and programmed from MDT’s “as built” plans for the highway, topographic maps, and video taken from a vehicle driving the route. Projected safety-related system deployments such as dynamic message signs and revised delineation can be electronically simulated on a geo-typical roadway. MDT engineers can “drive the roadway” to examine the impacts of prototype deployments. A sample of drivers can drive the scenarios to test the effectiveness of deployments. If changes in the systems are suggested, the simulation can be easily altered to represent the new specifications and the refinements. The primary benefit of the visualization and rapid prototyping approach using interactive, immersive simulators is that it provides an opportunity for formative evaluation, allowing engineers to refine the design at an early stage in the system development process before significant resources are invested in the deployment. The proposed system hardware and operations are all produced by computer graphics for a very small fraction of the cost of the actual deployment. Changes at this point may involve only a “click and drag” operation on a computer interface, changing one image for another, switching JPEG images of signs, or selecting alternative commands. By evaluating and refining the deployment early in the process, considerable time and money can be saved if changes need to be made to achieve the desired traffic objectives.]]></description>

      <title>Minding the Gap: Using Ground Based Rotating Lidar for 3D Viewing and Measuring</title>
      <link>https://trid.trb.org/View/839907</link>
      <description><![CDATA[A geospatial technology firm from the United Kingdom has developed and tested a custom suite of hardware and software for measuring a railway's loading gauge. Called "OmniGauge™", the system is designed to achieve high speed surveys of railways and other networks with complicated infrastructure. OmniGauge™ is a laser gauging implementation that provides a complete solution for scanning tunnels, platforms, trackside objects and roadbed. The profile of a tunnel, for example, can be scanned with the vehicle running at 60mph, whilst keeping data loss to a minimum to enable a 3- dimensional reconstruction of the tunnel's interior.]]></description>

      <title>Visualizing Metra: An Interactive Visualization Tool</title>
      <link>https://trid.trb.org/View/839904</link>
      <description><![CDATA[An interactive visualization tool, Visualizing Metra, was developed for Metra, Chicago’s regional commuter rail system, to support decision-makers in different departments requiring information about Metra’s stations, lines, ridership, land use, surrounding stations and connections to other transportation facilities. The application was developed as an intranet application in Macromedia Dreamweaver with a scalable base map with embedded links. The application allows the user to navigate visual, quantitative and text data. The strength of the application lies in its design. The design developed a template for each level in a spatial hierarchy providing a consistent approach to accessing information based on scale. Each level provides access to many different functions with common headers for navigation. The main frame has a GIS map of the station and surrounding suburbs. A zoom tools allows the user to see more or less detail. The secondary frames include track video and a slide show of the station area. The track video is accessible by clicking on the secondary window or on the video icon in the main window. Functions available at other levels include: 1. System level - ability to navigate directly to a line or station; 2. Line level - zoom tool and ability to navigate directly to a station via a list or the map; 3. Station and nearby blocks level - aerial photographs, socioeconomic data for the community; 4. Station level - access to detailed Autocad representation of station information, and navigable station panoramas; 5. Station building level - parking information. The prototype was developed in collaboration with Metra staff to address their needs for access to and display of information. The presentation describes the system from the point of view of the various users.]]></description>

      <title>5th International Visualization in Transportation Symposium and Workshop, October 23-26, 2006, Denver, Colorado</title>
      <link>https://trid.trb.org/View/839903</link>
      <description><![CDATA[The 5th International Visualization in Transportation Symposium and Workshop was held October 23-26, 2006 in Denver, Colorado.  The goal of the conference was to develop an awareness of visualization in the context of  transportation needs, and promote ideas for action that evolves the  ability to address those needs. To achieve this goal, the Symposium embraced four primary objectives: (1) Continue to promote the education and awareness of the benefits (realized and potential) of visualization technologies and practice as applied to the transportation industry; (2) For the first time, provide a program that brings together the diversity of expertise needed to deliver effective transportation programs in the context of visualization technologies and practice; (3) Provide a balance of traditional presentations and audience-engaging panel sessions on research, demonstration & practice; (4) Gather and document the knowledge exchanged and ideas generated in order to drive innovation in practice, targeted research, and technology development to evolve the use of visualization in transportation.]]></description>

      <title>3D Visualization and Micro-Simulation Applied to the Identification and Evaluation of Geometric and Operational ‘Solutions’ for Improving Visually Impaired Pedestrian Access to Roundabouts and Channelized Turn Lanes</title>
      <link>https://trid.trb.org/View/839905</link>
      <description><![CDATA[The Institute for Transportation Research and Education (ITRE) at North Carolina State University is responsible for an NCHRP funded effort to identify and evaluate roundabout and channelized turn lane treatments intended to improve facility access for visually impaired pedestrians. As part of this effort, ITRE is utilizing VISSIM micro-simulation/modeling capabilities to investigate the (estimated) effectiveness of proposed treatments in advance of their full scale field evaluation. While VISSIM provides effective animation capabilities for use by engineers for preliminary design, its primary focus is on the representation of traffic operations. While the program has a very useful AVI graphic output, it does not have the capability to generate the type of photo-realistic 3D models shown to be useful in public involvement settings. ITRE, working in conjunction with the NY State DOT has generated additional 3D visual environments showing the range of treatments and treatment combinations currently proposed. The principle audience for this work were the NCHRP “panel’ members whose responsibility it was to provide the go-ahead to the Phase II treatment implementation and evaluation phase. The paper provides an overview of how 3D visual simulation and micro-simulation/modeling were used in an integrated fashion to address geometric design and operational facility performance issues. The work is responsive to research needs identified by the TRB Visualization Technical Committee that call for more effective techniques for integrating real time and non real time simulation methods and for increased recognition of modeling requirements underlying the visual simulation of transportation system ‘operations.’ The methodology being employed in NCHRP 3-78 is an outgrowth of the use of VISSIM by an NIH funded bioengineering research partnership effort that was headed by Western Michigan University and supported by NC State University, Vanderbilt University, Johns-Hopkins, and Accessible Design for the Blind. This is the first time, to the authors' knowledge that photo-realistic visualization methods and computer simulation/modeling have been applied to this problem area.]]></description>

      <title>Using Visualization for the Design Process of Rural Roads</title>
      <link>https://trid.trb.org/View/839910</link>
      <description><![CDATA[The three-dimensional image of a road, which gives drivers all the important information for driving, is only obtained when three design levels are superimposed. If design engineers do not follow current standards during this complex process, shortcomings may occur and effect road safety. That’s why during the classical road design process he must check the three-dimensional alignment with the aid of perspective images. In order to be able to avoid shortcomings it is necessary to develop a new methodology of road design by using special three-dimensional design elements. The three-dimensional design can consist of fixed dialogue and coupling elements. The three-dimensional course of the route is visually represented using a real time simulation and the three-dimensional image can be checked by stereoscopic techniques.]]></description>

      <title>Visualization Data Standards for Planning and Design</title>
      <link>https://trid.trb.org/View/839935</link>
      <description><![CDATA[The goal of transportation planning and design is to develop solutions that improve communities in terms of mobility, safety, or even to provide an environment suitable for a pleasant afternoon of shopping and dining on Main Street. Because of the many purposes and needs that a road can provide, public stakeholders are often in conflict with each other about a project. These conflicts can be over anything from the overall purpose of the project to impacts to a specific old growth tree or stonewall. They can be expensive, with time and money invested in solutions that do not move forward. Visualization techniques that place the proposed design in existing site photography have become critical to support consensus building throughout planning and design. When a before and after photo is presented, a common question is “How accurate is this proposed visualization?” This really depends on the stage in project development and available data. For the purposes of this discussion, consider visualization data standard as the characteristics of the complete set of information that goes into making the final product.]]></description>

      <title>Towards an Advanced Spatio-Temporal Visualization System for the
Metropolitan Washington D.C.</title>
      <link>https://trid.trb.org/View/839906</link>
      <description><![CDATA[This paper delves on a suite of visualization approaches for exploring real-time and historical loop-detector data in the Washington Metropolitan D.C. region. To that endeavor, the authors have developed an effective web-based visualization system, the Advanced Interactive Traffic Visualization System (AITVS). The AITVS provides capabilities to browse the spatiotemporal dimensions hierarchy via roll-up and drill-down operations. It supports data visualization in a standard web-based environment where users can conveniently access the system via the Internet, thus facilitating the utilization of transportation information.]]></description>
