This poster session includes five papers covering subjects in visualization for support of transportation design, planning and construction. There are three posters demonstrating solutions using Building Information Modeling (BIM) including modeling of historic sites, airport asset management, and design of steel bridge structures. Two posters demonstrate applications of virtual reality (VR) technologies applications to traffic analysis and design of urban streets

The growing necessity to recover and digitally represent heritage infrastructure, has led the experts to face the challenge of choosing different Building Information Modeling (BIM) platforms that will be used to manage the implementation of the semi-automatic design and the reconstruction processes of reverse engineering modelling. The approach to the integrated management of information derived through Heritage-BIM (H-BIM) has been applied to Via del Duomo, one of the main roads in the old town of Naples, Italy. During preliminary inspections of the construction site, it was possible to acquire geometric features and stratigraphic information as well as conducting a photographic survey. Subsequently, the acquired data were processed to obtain a mesh using Dynamo as BIM-based tool. Then, a library, with the inclusion of all the possible stone paving package alternatives, was created in order to design an algorithm able to select the optimal solution in the listed library depending on the context, including all the structural and stress-deforming characteristics . The research has considerable potential in the field of facility management for the enhancement of the existing building and infrastructural heritage.

In today’s modern world, aging infrastructure falls short of addressing the rapidly changing demands of the society. Airports -forming one of the most important economic engines- play an essential role within the infrastructure industry. Addressing inefficiencies in capital expenditures (CapEx) and operational expenditures (OpEx) via digitally transformative approaches has become a forefront topic. As one of the promising digital process techniques in Architecture, Engineering, Construction, and Operation (AECO) industry, Building Information Modeling (BIM) is fundamental for enabling a digital platform to efficiently manage project lifecycle. This study proposes a novel scalable BIM-based digital platform architecture, which leads to hosting an airport digital twin, for streamlined management of airport asset lifecycle data. The research methodology includes literature and industry review, an online survey, focus group discussions for data collection; mixed method analysis for data analysis; and Model Based System Engineering (MBSE) with Systems Modelling Language (SysML) for data mapping. Establishing a BIM-enabled digital platform architecture is expected to enhance asset management practices via co-creating value across various management disciplines.

The recent push to adopt building information modeling (BIM) for bridges and structures in the transportation industry has encountered major barriers due to the lack of standardization. Unlike the building industry that has the U.S. National BIM (NBIMS) standard as a formal standard and guide for the development of interoperable BIM software, the transportation industry does not currently have a similar standard to enable the creation of interoperable BIM software to serve the needs of transportation stakeholders. The purpose of this paper is to present the findings of the research that developed the one of the first use cases of adopting the National BIM standard for the transportation industry. A subcommittee of the Association of State Highway and Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) Steel Bridge Collaboration was formed to conduct a pilot study in the creation of information delivery manuals (IDM) for steel bridges. This study serves as pilot for the development of future IDMs in the transportation industry. As a result, the current “IDM for Steel Bridge Detailing and Fabrication” serves as the starting point of the TPF-5(372) BIM for Bridges and Structures development of the Design to Fabrication Model View Definition (MVD). Finally, this study provides the outcomes and recommendations needed to expediate the development of IDMs for other use cases in the bridge and transportation industry.

While the development of cities focuses on improving traffic mobility, it has gradually neglected people’s demand for safety and comfort walking on the streets. To address this problem, shared streets that can integrate traditional street life and traffic mobility are getting more attention as pedestrian-friendly development. The shared street aims to ensure pedestrian safety in the roads and reduce the dominance of vehicles by allocating all road elements in the same road layer. In order to measure shared street effectiveness, it is essential to identify how people feel when driving and walking around. However, investigating the various factors that influence the real world is not simple because of cost, time-consuming, and safety problems. Virtual reality and the Human-in-the-loop(HIIL) have become useful tools for conducting experiments without compromising them. The experiments are performed on both pedestrians and drivers’ sides. The three shared street layouts in a virtual environment designed according to the real shared street examples implemented in Milan and South Kensington, Europe. For the evaluation of shared street effects, questions in five aspects are asked to participants. MPR, EWM, and Fuzzy Comprehension Evaluation method are used to assess the performance. The results revealed that different groups of people have different sensitivity and preferences regarding amenity, walking or driving experience, safety, and environmental aspects. The city planners can get helped through this shared street analysis where the new design and layout of the shared street could be tested in advance.

Although there have been efforts to achieve the zero deaths on horizontal construction projects, undesired crashes within work zones continue to happen, highlighting the need for continuous studies on work zone safety improvements. An advantageous tool to be used in such studies is the Virtual Reality (VR) technology, as it provides a safe and highly realistic environment for performing behavioral experiments without endangering the participants. However, researchers still face the challenge of integrating real-world traffic data and interactions in VR back to simulation environments. This study presents the development of an integrated platform that allows a two-way interface between traffic simulation packages (e.g., SUMO) and VR environments (e.g., Unity 3D). The integrated platform enables both applications to spontaneously interact with each other to represent realistic traffic and work zone conditions in the VR environment. The main contribution of this study is the development of the integrated and immersive platform and its customized API tool, called Traffic Simulation-Virtual Reality Integration (TSVRI). The TSVRI API, which bidirectionally transfers information between simulation and VR in real-time, guarantees that the VR environment represents the dynamic characteristics of the work zone traffic and user interactions are fed back to the simulation model to continuously update the traffic information. The integrated platform was tested in alpha experiments and shown to be effective to reproduce realistic traffic scenarios, scalable to different work zone settings (long-, intermediate-, short-term, or mobile), and is ready to be used in experiments with a higher number of participants with different construction experience.
