Evaluation of Work Zone Speed Reduction Measures, 2000

The Iowa Department of Transportation (DOT) has made improving work zone (WZ) safety a high priority. Managing vehicle speeds through work zones is perceived to be an important factor in achieving this goal. A number of speed reduction techniques are currently used by transportation agencies throughout the country to control speeds and reduce speed variation at work zones. The purpose of this project is to study these and other applicable work zone speed reduction strategies. Furthermore, this research explores transportation agencies' policies regarding managing speeds in long-term, short-term, and moving work zones. This report consists of three chapters. The first chapter, a literature review, examines the current speed reduction practices at work zones and provides a review of the relevant literature. The speed control strategies reviewed in this chapter range from posting regulatory and advisory speed limit signs to using the latest radar technologies to reduce speeds at work zones. The second chapter includes a short write-up for each identified speed control technique. The write-up includes a description, the results of any field tests, the benefits and the costs of the technology or technique. To learn more about other state policies regarding work zone speed reduction and management, the Center for Transportation Research and Education conducted a survey. The survey consists of six multipart questions. The third chapter provides summaries of the response to each question.

Preliminary Engineering Work Area, 1981

The purpose of the audit is to provide a report to management of the adequacy of controls employed to manage this work area. Where appropriate, recommendations and comments are provided for management consideration. Consideration is given to compliance with applicable policies and procedures, both federal and state. Economy and efficiency of operations are considered to the degree feasible but are not primary objectives.

Iowa Courts Work for Iowans, January 13, 2010

There is much more to the work of the courts than the occasional high-profile case that attracts public attention. The bulk of our work involves everyday problems that affect ordinary Iowans.
