摘要:
Embodiments of the invention are generally directed toward methods, systems, and computer-readable media for prioritizing bridge repairs. A bridge score is generated that represents various factors such as conditions, load issues, risk of failure, and importance. Repairs to bridges or bridge segments that pose a greater risk may be prioritized before repairs made to bridges posing a lower risk.

Embodiments of the invention are generally directed toward methods, systems, and computer-readable media for prioritizing bridge repairs using a risk-based analysis. An overall risk factor is generated for each of a plurality of bridges. The overall risk factor represents the probability of failure times the consequence on failure for the bridge. Repairs to bridges that pose a greater risk may be prioritized before repairs made to bridges posing a lower risk.

Generating a scanned-surface model representing a scanned surface includes various steps. For example, instrument model coordinates may be obtained that represent a position of the instrument in the 3D model. In addition, surface-distance measurements may be derived describing a distance from the scanned surface. Inertial measurements are also recorded. The instrument model coordinates, surface-distance measurements, and inertial measurements are correlated and filtered by a rules based selection process to determine scanned-surface model coordinates.

Methods and systems for building a stress ribbon structure over an opening via incremental launching, a construction fixture, a support structure, an anchorage panel, and a stress ribbon structure are disclosed. Construction fixtures are constructed adjacent to a support structure. The stress ribbon structure is constructed in a staging area and in sections that are suspended between the construction fixtures. Anchorage panels at each end of a section engage a blister on the construction fixtures and the support structure. Completed sections are launched from the construction fixtures onto and along the support structure. Sections are individually constructed and launched and adjacent sections abut along a lateral edge. Adjacent sections are aligned by adjusting tension in integral support cables and their ends pivot or rotate about the blisters via a bearing system with both rotational flexibility and low friction to support sliding in the direction of launching.

Travel-demand forecasting methods are described for predicting traffic volume based, at least in part, on user-entered data in the form of anticipated traffic routes, demographic data and/or other types of socioeconomic data. This data can source a prediction algorithm or be used to forecast traffic patterns. Methods and systems are described for, among other things, optimizing traffic predictions, forecasting traffic patterns using user-assigned trip patterns, associating rich attribute information to navigation routes, exposing personal-logistic information to a group, communicating traffic-situation-generated alerts based on user information, optimizing a presentation of user-defined traffic routes, and presenting location indications based on proximity (temporal or geographical).

The invention generally relates to enabling the management of survey data. One embodiment includes providing an upload description that describes characteristics of survey data to be uploaded, assigning a thread to process a group of files that store aspects of the survey data, dividing the file into data chunks, deriving from a given data chunk a corresponding data-integrity value and respectively associating the same with the given data chunk, communicating the data chunks to a remote storage device, utilizing the corresponding data-integrity values to ensure successful communication of the data chunk, and spatially storing the survey data such that it is retrievable upon a request that describes a geographic area of interest.
