• Abstract:
  Effects of earthquake damage to highway components such as bridges and roadways can go well beyond life-safety risks and costs to repair damaged structures. Such damage can also severely disrupt traffic flows that can
  
  impact the region’s economy and its post-earthquake emergency response and recovery. These impacts will
  
  depend not only on the seismic performance of the components, but also on the characteristics of the overall
  
  highway system such as its network configuration and its trip demands. Unfortunately, such traffic impacts are
  
  usually not considered in seismic improvement activities at transportation agencies. One reason has been the
  
  lack of a technically sound and practical methodology for estimating these impacts. The Federal Highway
  
  Administration (FHWA) has funded research through the Multidisciplinary Center for Earthquake Engineering
  
  Research (MCEER) to develop methods to reduce the seismic vulnerability of roadway systems and
  
  components over the past 12 years. One of the tasks in this research program has focused on the development,
  
  programming, and application of a new state-of-the-art methodology for deterministic and probabilistic seismic
  
  risk analysis (SRA) of roadway systems nationwide. This work has culminated in the recent release of a software
  
  package named REDARS™ 2 for assessing the time-dependent impacts of earthquakes on a transportation
  
  network in terms of traffic delays and economic losses. In addition, over the past three years, the California
  
  Department of Transportation (Caltrans) has carried out a REDARS™ Demonstration Project. This project,
  
  which is described in this report, was aimed at transferring technical expertise from the developer community at
  
  FHWA and MCEER to Caltrans. In particular, the project was to enable Caltrans’ staff to assess the applicability
  
  of the REDARS™ for: (a) pre-earthquake planning of seismic-risk-reduction measures; and (b) post-earthquake
  
  emergency response in real time after an actual earthquake. The project has also supported the improvement of
  
  several models within REDARS™ -- which is an effort that was facilitated by close interaction between the
  
  REDARS™ Development Team (RDT) and Caltrans staff. Finally, Caltrans’ staff has beta tested the REDARS™
  
  2 software, and has provided the RDT with helpful suggestions for future methodology and software upgrades.
