Engineering Study Automating Iowa's Speed Monitoring Program, HR-228, 1983

Excessive speed on State and County highways is recognized as a serious problem by many Iowans. Speed increases both the risk and severity of accidents. Studies conducted by the FHWA and NHTSA have concluded that if average speeds were increased by five MPH, fatalities would increase by at least 2,200 annually. Along with the safety problems associated with excessive speed are important energy considerations. When the national speed limit was lowered to 55 MPH in 1974, a tremendous savings in fuel was realized. The estimated actual savings for automobiles amounted to 2.2 billion gallons, an average of 20.75 gallons for each of the 106 million automobiles registered in 1975. These benefits prompted the Federal-Aid Amendment of 1974 requiring annual State enforcement certification as a prerequisite for approval of Federal-aid highway projects. In 1978, the United States D.O.T. recommended to Congress significant changes in speed limit legislation designed to increase compliance with the national speed limit. The Highway Safety Act of 1978 provides for both withholding Federal-aid highway funds and awarding incentive grants based on speed compliance data submitted annually. The objective of this study was to develop and make operational, an automatic speed monitoring system which would have flexible capabilities of collecting accurate speed data on all road systems in Iowa. It was concluded that the Automatic Speed Monitoring Program in Iowa has been successful and needed data is being collected in the most economical manner possible.

Evaluation of Limestone Filler in Gravel Mixtures "Asphaltic Concrete", R-228, 1968

This study was designed to provide background information on asphaltic concrete mixtures peculiar to northwest Iowa. This background is necessary to provide the basis for future specifications. There were several projects let in 1967 involving l", 3/4" and 3/8" mixes of Type "B'' asphaltic concrete which specified in part, II Not less than 40% of the material passing the No. 200 sieve shall be pulverized limestone or mineral filler, but in no case shall the per cent of pulverized limestone or mineral filler passing the No. 200 sieve be less than 2%. No credit will be allowed for limestone in gravel - II Northwest Iowa has no suitable limestone or mineral filler locally available. As a result, this material has to be imported, raising the cost of the mix approximately twenty-five cents per ton. The purpose of this study, therefore, was designed to compare some original job mix samples with alternate mixes from the same local material, but without the addition of pulverized limestone or mineral filler. Since the filler from the crushed gravel does not have the same crushing characteristics or sieve analysis as the pulverized limestone or mineral filler, they could not be compared on an equal percentage basis. Therefore, the alternate mixes were made to conform to the following proposed specification, "No less than 40% of the material passing No. 200 sieve shall be pulverized limestone or mineral filler or a 100% crushed gravel, but in no case shall the per cent of pulverized limestone or mineral filler or a 100% crushed gravel passing the No. 200 sieve be less than 2%."

Department of Human Rights Division of Central Administration Performance Plan, FY2005

This report provides valuable information about Central Administration’s coordination and provision of quality administrative, personnel, and financial services for all DHR divisions. Information is being provided in accordance with the Accountable Government Act to improve decision-making and increase accountability to stakeholders and citizens of Iowa. This report includes performance information for the division’s core function - resource management. The two services, products, and activities provided by the division – financial services and human resources services - also are reviewed. The division is comprised of seven full-time employees. The division’s FY2005 operating budget was $ 604,888 of which $292,660 was from the State General Fund. The additional $ 312,228 was received via intra-state transfers from the non-state funded programs administered by the Department of Human Rights. Central Administration oversaw expenditures of $ 66,868,806 for the entire department, and coordinated the personnel and payroll transactions of 56 FTEs. As we review the results from this year’s report we will continue to refine how we measure our successes and modify plans to improve results.
