“…Computer programs such as FORTRAN 77 have been used for aspects of highway optimization design, but did not integrate CAD drawings (Dhillon 1991). Computer programs have also been used in the past for optimizing of road network planning (Kiyota 1999). Others researched used algorithms with geographic information systems (GIS) to optimize highway alignment for cost effectiveness and proper time management (Jha et al 2004 andKang et al 2011).…”

This study proposes a 3D visualization model in highway design/construction that electronically represents information of highway projects. The 3D model will be based on the STEP (Standard for the Exchange of Product model data), which is an open standard, so it can be used as data structures. Since the design model includes integrated resources to represent 3D geometric shape and project management information of the infrastructure, the built visualization model will allow end-users to extract the necessary data from the object based 3D intelligent model. This integrated data model is expected to provide practical engineering information to improve the design/construction process. This study presents the framework for the integration of application programs such as existing 3D/CAD programs used in practice by applying the STEP-based information model and information technologies. With the system integration framework composed of the information model, data repository, application program, and application programming interface, this research proposes establishing a prototype system according to the system integration framework so that end-users can manage information of an infrastructure in an integrated computing environment. The final output of this research is to present a methodology to automatically generate a construction schedule from infrastructure facility design information. This method is performed by the full connection between construction quantity takeoff analysis and design information by using the information model.

Policymakers interested in evaluating the costs and benefits of earthquake retrofit and reconstruction strategies require a way to measure the benefits (costs avoided) of competing proposals. This requires an integrated, operational model of losses due to earthquake impacts on transportation and industrial capacity, and how these losses affect the metropolitan economy. Our approach to this problem advances the information provided by transportation and activity system analysis techniques in ways that help capture the most important economic implications of earthquakes. These full cost results have four dimensions: structure damage, business interruption, network performance, and infrastructure damage. Preliminary results for all four measures are summarized for a hypothetical magnitude 7.1 earthquake on the Elysian Park blind thrust fault in Los Angeles.

“…The disruption of a transportation network can have substantial consequences on an economy, either at a local, regional, or national level (Kim et al, 2002;Ham et al, 2005a, Ham et al, 2005b, Sohn et al, 2003. Given these impacts, research has been conducted to aid engineers and planners in finding optimized reconstruction schedules following such disruptions (Lee and Kim, 2007;Chen and Tzeng, 1999;Kiyota et al, 1999) or identify network vulnerabilities (Matisziw and Murray, 2009;Ball et al, 1999). While useful for long-term planning, such research fails to address transient traffic dynamics in the short term.…”

This paper discusses the observed evolution of traffic in the Minneapolis-St Paul (Twin Cities) region road network following the unexpected collapse of the I-35W Bridge over the Mississippi River. The observations presented within this paper reveal that traffic dynamics are potentially different when a prolonged and unexpected network disruption occurs rather than a preplanned closure. Following the disruption from the I-35W Bridge's unexpected collapse, we witnessed a unique trend: an avoidance phenomenon after the disruption. More specifically, drivers are observed to drastically avoid areas near the disruption site, but gradually return after a period of time following the collapse. This trend is not observed in preplanned closures studied to date. To model avoidance, it is proposed that the tragedy generated a perceived travel cost that discouraged commuters from using these sections. These perceived costs are estimated for the Twin Cities network and found to be best described as an exponential decay cost curve with respect to time. After reinstituting this calibrated cost curve into a mesoscopic simulator, the simulated traffic into the discouraged areas are found to be within acceptable limits of the observed traffic on a weekby-week basis. The proposed model is applicable to both practitioners and researchers in many traffic-related fields by providing an understanding of how traffic dynamics will evolve after a long-term, unexpected network disruption.
