Infrastructure and Transportation Task Force Report, August 2008

The Rebuild Iowa Infrastructure and Transportation Task Force is acutely aware of the critical role infrastructure plays in Iowa’s communities, the lives of the residents, and the economic well-being of the state. With encouragement to the Rebuild Iowa Advisory Commission (RIAC) for its consideration of great need for infrastructure and transportation repairs, the Task Force provides its assessment and recommendations. As the RIAC fulfills its obligations to guide the recovery and reconstruction in Iowa, infrastructure and transportation must be recognized for its impact on all Iowans. The tornadoes, storms, and floods were devastating to infrastructure and transportation systems across the state. The damage did not distinguish between privately-owned and public assets. The significance of the damage emerges further with the magnitude of the damage estimates. Infrastructure includes components that some might initially overlook, such as communication systems, landfills, and water treatment. The miles of damaged roads and bridges are more evident to many Iowans. Given the reliance on infrastructure systems, many repairs are already underway, though gaps have emerged in the funding for repairs to certain infrastructure systems.

Women, Work and the Iowa Economy, September 2008

Women play a substantial and crucial role in the Iowa economy. Women make up almost half the labor force, participating in the labor force at one of the highest rates in the nation. At the same time, disparities persist as to women’s prospects for success in that same economy. For instance, although women in Iowa are more likely than men to receive post-secondary education, they are also more likely to be in poverty and to earn a lower wage than male peers. The “gender gap,” the difference between male and female wages, is a much-discussed but often misunderstood tool that helps measure women’s success in the workforce. Women’s median wages are lower than men’s median wages largely because of differences in male and female occupations and work history, although gender discrimination in the workforce also plays a role. This report investigates Iowa’s gender gap in ways that clearly show both its causes and effects and suggests policy responses that could ensure women’s full and equal participation in Iowa’s economic future. Understanding the differences between men’s and women’s experiences in the state economy is important for developing policies that can effectively address barriers to economic success for all Iowans.

Relationship between Speed and Lateral Position on Curves, September 2012

Excessive speed is often cited as a primary driver factor in crashes, particularly rural two-lane crashes. It has also been suggested that speed plays a significant role in crashes on curves. However, the relationship between speed and crashes on curves is not well documented because it is difficult to determine driver speed after the fact when investigating a crash. One method to begin documenting this relationship is to explore the relationship between lateral position and speed as a crash surrogate. For this study, the researchers collected speed and lateral position data for three rural two-lane curves. The relationship between lateral position and speed was assessed by comparing the odds of a near-lane crossing for vehicles traveling 5 or more mph over the advisory speed to those for vehicles traveling below that threshold.
