Guidelines for Development of Smart Apps for Assessing, Coding, and Marking Highway Structures in Emergency SituationsTRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 223: Guidelines for Development of Smart Apps for Assessing, Coding, and Marking Highway Structures in Emergency Situations provides guidance for developing mobile devices-based smart applications for preliminary damage assessment responders to use in emergency scenes for assessing, coding, and marking transportation structures. The primary intent of this manual is to facilitate communication between structural engineers, responders, inspectors, and the IT professionals who will develop and manage the application and associated data. The report includes guidelines for developing interfaces, basic functions, and server or cloud-side services to support the smart functions. The smart application automates the manual and paper-based assessing, coding, and marking procedures, which are described in detail in NCHRP Research Report 833: Assessing, Coding, and Marking of Highway Structures in Emergency Situations, Volume 2: Assessment Process Manual and Volume 3 Coding and Marking Guidelines. |
DEVELOPMENT OF OPTIMIZED 20-YEAR PRESERVATION PLAN FOR IOWA STATE OWNED BRIDGE INVENTORY: Phase IIThe Iowa Department of Transportation (Iowa DOT), in collaboration with IDS Inc., is undertaking a study to investigate the development of a new multi-objective optimization technique to develop long-term optimal renewal plans for Iowa’s state-owned bridge inventory. The first phase of the study investigated trade-offs between funding levels and system-wide performance and risk levels by quantifying the impact of funding levels on the network’s overall condition and risk levels and determining required funding to achieve desired condition or risk targets. Phase II builds on results from the first phase to further extend and enhance the analysis and optimization methods to better meet the requirements of Iowa DOT and be more aligned with current planning practices and policies. Phase II has implemented several recommendations furnished by Iowa DOT engineers to address several limitations in the first phase of the project. A report is available containing information pertaining to the second phase of the project. Readers of this Phase II Progress Report should become familiar with the contents of the project proposal and previous progress reports. |
