OVERVIEW: The Southern Plains Transportation Center (SPTC) is a regional university transportation center focused on climate adaptive transportation and freight infrastructure. An active partner of the SPTC is the University of Oklahoma Center for Intelligent Transportation Systems (OU-CITS). OU-CITS was established in 1998 as the OU ITS Lab – a joint venture between the Oklahoma Department of Transportation (ODOT) and the OU School of Electrical and Computer Engineering. OU-CITS has assisted ODOT with the design and integration of Oklahoma’s statewide intelligent transportation system (ITS) since the beginning of that program. In cooperation with ODOT, OU-CITS implemented the first fully distributed, virtual Traffic Management Center. OU-CITS members share their expertise through training transportation agents in ITS technology. OU-CITS also works closely with other transportation stakeholders including the Oklahoma Department of Public Safety and municipal police agencies. Recently, OU-CITS collaborated across state agencies in the cooperative development of a Traffic Incident Management system as part of the statewide implementation of ITS (Figure 1). Additionally, the collaboration has produced a related research project that involves using connected vehicle technology to improve traveler safety in inclement weather. The collaboration between the OU-CITS and the SPTC is, therefore, unique in that the collaborative projects range from pure research to real deployment of systems.
PRODUCT DEVELOPMENT: The SPTC has facilitated and supported a collaborative effort between the OU-CITS, ODOT and the USDOT’s Traffic Safety Institute (TSI) in Oklahoma City to create training materials in the ITS area. Under the USDOT’s training mission, TSI provides multi-modal transportation safety training across the country. These modules consist of three key ITS areas, namely passenger vehicles, commercial vehicles and transit, and will be delivered by TSI in their training courses nationally to transportation professionals from Federal, State, and local government agencies, and the private sector.
The most significant product, so far, resulting from this collaboration is a Case Study entitled “ITS in Severe Weather Incident Management.” This case study ties closely to the SPTC’s focus on Climate Adaptive Transportation and Freight Infrastructure. The SPTC, OU-CITS and ODOT provided their domain expertise in developing this case study.
The “ITS in Severe Weather Incident Management” case study is based on the experiences of transportation agents from the May 2013 extreme weather events in Oklahoma. On May 19-20, 2013, Central Oklahoma was struck by a number of tornadoes, including an EF5 tornado that struck Moore, OK on the afternoon of May 20 (Figure 2).
According to the Oklahoma Department of Emergency Management, this single tornado in the southern portion of the Oklahoma City Metropolitan area killed 24 people and caused an estimated $2 billion in damages (Figure 3).
Many of the challenges introduced in the case study were faced by transportation engineers in the early aftermath of the May 20th severe weather event. Highways were blocked by damaged vehicles and some ITS infrastructure was damaged or destroyed (Figure 4). In addition to direct damage, electrical outages caused loss of power to several permanent ITS resources. Overloading of cellular networks caused communication difficulties.
The developed case study helps participants to familiarize with ITS technologies and asks them to assume the role of a DOT engineering team as they respond to a major extreme weather event. Teams utilize permanent and portable Dynamic Message Signs (DMSs), Advanced Traveler
Information Systems (ATIS, shown in Figure 1), and other resources to inform motorists about safety hazards and re-route interstate highway traffic during and in the aftermath of a major extreme weather event. As part of the case study, these teams meet on a second day to discuss their response. One of the unique aspects of this case study, “ITS in Severe Weather Incident Management,” is the set of secret envelopes. These envelopes give team members their own set of unique and unexpected challenges and provide dynamic complications that transportation engineers face in responding to disaster events and demonstrates the need for flexibility. While this study focuses on a tornado event, the challenges and approaches introduced are applicable to a variety of severe weather events including flooding and hurricanes.
PRODUCT IMPLEMENTATION: The case study was tested by Civil Engineering students in their Transportation Engineering course in the Spring of 2016. The participants provided a strong and positive feedback on the effectiveness of the case study. It will next be presented to engineers from ODOT’s Maintenance Division. In addition to the three ITS training modules, the SPTC and OU-CITS look forward to future opportunities to share their experience and expertise through collaboration with TSI and the development of training materials. These modules are expected to enhance driver safety and have local, regional and national impacts in the training of transportation professionals who manage severe weather incidents.
