The Center for Transportation Research and Education performed a traffic signal inventory study for the Iowa Department of Transportation. The purpose of this study was to determine the level of compliance with the Manual on Uniform Traffic Control Devices (MUTCD) and other industry standards of traffic signals on the state highway system. Signals were randomly selected throughout the State of Iowa. Only signals in cities with a population less than 5,000 were considered. Several intersections need to be addressed immediately to correct clearance timing settings. Red clearance intervals were frequently too short. A handful of intersections had inadequate pedestrian clearance times. Six intersections had at least one yellow clearance interval that did not meet Institute of Transportation Engineers standards. Some of the intersections likely would not meet traffic signal warrants and should be investigated for possible removal. The most common problem found with traffic signals was a lack of maintenance. Many of the signals had at least one of the following problems: burned out lights (signals and/or pedestrian heads), pedestrian lenses in need of replacement, dirty cabinet/missing or poor filter, missing visors, or inoperative pedestrian push buttons. Timing sheets were frequently missing or out of date. Another frequent noncompliance issue was the use of backplates. The MUTCD states that backplates should be used on signals viewed against a bright sky. The majority of signals inventoried did not have backplates on the mast-arm mounted signals. The timing at some intersections could likely be improved by reducing the cycle length. Where there were multiple signals in close proximity rarely was there any attempt at signal coordination. Finally, a number of intersections had equipment that by today’s standards would be considered obsolete.

The Iowa Department of Education, in collaboration with CASAS, initiated an English Literacy Pilot project during program Year 2001 (July 1, 2001- June 30, 2002). The overall goal of the project is to research and identify promising instructional strategies and curriculum offerings designed to meet the unique learning needs of Iowa's adult immigrant target populations.

Governor Vilsack and Lt. Governor Pederson are encouraging the development of a strategic community plan to encourage a smooth transition for bringing skilled workers and their families to Iowa from other countries. Skilled workers from other countries can provide a valuable resource to Iowa employers and can add cultural richness and diversity to Iowa's communities. New Iowans can help Iowa's communities, businesses, and economy grow
