Strategic Plan Iowa Workforce Development October, 2004

For the 2004 strategic planning process at Iowa Workforce Development, Director Richard Running asked for as much input from all staff as possible. As a result, planning staff designed an extensive process to gather input over about a three month period during the late spring and summer: • A Guide to Staff Involvement was drafted and distributed to staff in offices throughout the state. This guide provided a brief explanation of the planning process and quoted extensively from the Vilsack/Pederson Leadership Agenda and the 2003 IWD strategic plan to illustrate each step and to show examples of alignment. The guide also provided suggestions for staff in various locations and work units to conduct their own planning sessions. The structure was designed to solicit feedback regarding elements (vision, mission, guiding principles, goals and strategies) of the existing 2003 plan. Particular attention was devoted to securing non-management staff’s perspective during the internal and external assessment exercises. • Several local offices did conduct their own structured input sessions following the suggested guidelines and sent the results to planning staff in the central administrative offices. • Other work units in many locations opted to ask planning staff to facilitate planning sessions for them. The results of these sessions were also gathered by planning staff. In all, dozens of input sessions were held and hundreds of IWD staff participated directly in the process. Because all the sessions followed similar guidelines, it was relatively easy to combine all of the input received and spot common themes that surfaced from the many sessions. A composite of all the flip chart notes was compiled into one large document (for those who like lots of detail) and another document summarized the key themes that emerged. This information was used in a day-long planning retreat on August 20. Management staff members from throughout the department were invited and each work unit and sub-state region also brought a non-management staff person as well. This group reviewed the themes from the earlier sessions and then addressed each element of the 2003 plan, proposing refinements for almost all sections. Subsequently, senior management reviewed the results of the retreat and made the final decisions for the new 2004 plan. This thorough approach, with its special emphasis on input from line staff, did result in some significant changes to IWD’s plan. Local office staff, for example, consistently expressed the need to step up our marketing efforts, especially with employers. Another need that was expressed clearly and often was the need to beef up staff training efforts, much of the capacity for which had been lost in budget and staff reductions a few years ago. Neither of these issues is new, but the degree of concern expressed by IWD staff has caused us to elevate their importance in this year’s plan.

On The Spot Damage Detection Methodology for Highway Bridges, July 2010

Vibration-based damage identification (VBDI) techniques have been developed in part to address the problems associated with an aging civil infrastructure. To assess the potential of VBDI as it applies to highway bridges in Iowa, three applications of VBDI techniques were considered in this study: numerical simulation, laboratory structures, and field structures. VBDI techniques were found to be highly capable of locating and quantifying damage in numerical simulations. These same techniques were found to be accurate in locating various types of damage in a laboratory setting with actual structures. Although there is the potential for these techniques to quantify damage in a laboratory setting, the ability of the methods to quantify low-level damage in the laboratory is not robust. When applying these techniques to an actual bridge, it was found that some traditional applications of VBDI methods are capable of describing the global behavior of the structure but are most likely not suited for the identification of typical damage scenarios found in civil infrastructure. Measurement noise, boundary conditions, complications due to substructures and multiple material types, and transducer sensitivity make it very difficult for present VBDI techniques to identify, much less quantify, highly localized damage (such as small cracks and minor changes in thickness). However, while investigating VBDI techniques in the field, it was found that if the frequency-domain response of the structure can be generated from operating traffic load, the structural response can be animated and used to develop a holistic view of the bridge’s response to various automobile loadings. By animating the response of a field bridge, concrete cracking (in the abutment and deck) was correlated with structural motion and problem frequencies (i.e., those that cause significant torsion or tension-compression at beam ends) were identified. Furthermore, a frequency-domain study of operational traffic was used to identify both common and extreme frequencies for a given structure and loading. Common traffic frequencies can be compared to problem frequencies so that cost-effective, preventative solutions (either structural or usage-based) can be developed for a wide range of IDOT bridges. Further work should (1) perfect the process of collecting high-quality operational frequency response data; (2) expand and simplify the process of correlating frequency response animations with damage; and (3) develop efficient, economical, preemptive solutions to common damage types.

On the spot damage detection methodology for highway bridges (tech transfer summary)

The objective of this work was to develop a low-cost portable damage detection tool to assess and predict damage areas in highway bridges. The proposed tool was based on standard vibration-based damage identification (VBDI) techniques but was extended to a new approach based on operational traffic load. The methodology was tested using numerical simulations, laboratory experiments, and field testing.

Endeavors Update, Iowa Medicaid Enterprise: Late Addition, Vol. 1, Issue 7, February 24, 2011

The Iowa Medicaid Enterprise (IME) is an endeavor, started in 2005, to unite State staff with “best of breed” contractors into a performance-based model for administration of the Medicaid program.

Effectiveness of Dynamic Messaging on Driver Behavior for Late Merge Lane Road Closures, 2009

Efforts to improve safety and traffic flow through merge areas on high volume/high speed roadways have included early merge and late merge concepts and several studies of the effectiveness of these concepts, many using Intelligent Transportation Systems for implementation. The Iowa Department of Transportation (Iowa DOT) planned to employ a system of dynamic message signs (DMS) to enhance standard temporary traffic control for lane closures and traffic merges at two bridge construction projects in western Iowa (Adair County and Cass County counties) on I-80 during the 2008 construction season. To evaluate the DMS system’s effectiveness for impacting driver merging actions, the Iowa DOT contracted with Iowa State University’s Center for Transportation Research and Education to perform the evaluation and make recommendations for future use of this system based on the results. Data were collected over four weekends, beginning August 1–4 and ending October 16–20, 2008. Two weekends yielded sufficient data for evaluation, one of transition traffic flow and the other with a period of congestion. For both of these periods, a statistical review of collected data did not indicate a significant impact on driver merging actions when the DMS messaging was activated as compared to free flow conditions with no messaging. Collection of relevant project data proved to be problematic for several reasons. In addition to personnel safety issues associated with the placement and retrieval of counting devices on a high speed roadway, unsatisfactory equipment performance and insufficient congestion to activate the DMS messaging hampered efforts. A review of the data that was collected revealed different results taken by the tube counters compared to the older model plate counters. Although variations were not significant from a practical standpoint, a statistical evaluation showed that the data, including volumes, speeds, and classifications from the two sources were not comparable at a 95% level of confidence. Comparison of data from the Iowa DOT’s automated traffic recorders (ATRs) in the area also suggested variations in results from these data collection systems. Additional comparison studies were recommended.
