Corridor management pilot projects by David Plazak( Book )

2 editions published in 2004 in English and held by 15 WorldCat member libraries worldwide

Managing existing and newly constructed highway corridors has recently become a significant concern in many states, including Iowa. As urban land and land on the urban fringe develops, there is pressure to add features such as commercial driveways, at-grade public road intersections, and traffic signals to arterial highway routes that should primarily serve high-speed traffic. This diminishes the speed and traffic capacity of such roadways and can also cause significant safety issues. if mobility and safety are diminished, the value of the highway investment is diminished. Since a major highway corridor improvement may cost tens of millions of dollars or more, corridor management is as critical to preserving that investment as is more "hard side" management practices such as pavement or bridge management. Corridor management is a process that applies access management principles to highway corridors in an attempt to balance the competing needs of traffic service, safety, and support for land development. This project helped to identify routes that should be given high priority for corridor management. The pilot study in the form of two corridor management case studies provides an analytical process that can be replicated along the other Iowa commuting corridors using commonly available transportation and land use data resources. It also offers a general set of guidelines for the Iowa Department of Transportation to use in the development of its own comprehensive corridor management program
Access management awareness program by T. H Maze( Book )

2 editions published in 1997 in English and held by 14 WorldCat member libraries worldwide

This report presents the results of a number of detailed Iowa access management case studies. Case studies were selected to provide a cross-section of locations and community sizes in Iowa as well as a variety of project types. Generally, access management projects completed during the mid-1990s were chosen as case studies. Projects ranging from driveway consolidation to full raised medians were analyzed on a before and after basis in terms of traffic safety, traffic operations, and adjacent business vitality. Sources of information used for the case study analysis included: road project files; traffic accident records; state sales tax records; and personal interviews of business owners, business customers, and local officials. The case study results from Iowa essentially confirm results of previous access management research from around the nation. Recent access in Iowa had significant, positive impacts in terms of traffic safety. The average reduction of annual accidents and accident rates on improved roadways was approximately 40%. Improvements in access management also led to significantly better roadway operations for most case studies. Although a small number of individual businesses do report sales losses and/or customer complaints once projects have been completed, access management projects in Iowa have not had an adverse impact on the majority of businesses located along them. In fact, some access management projects in Iowa seem to have contributed to an improved business environment along the corridors that have been improved. The results from the Iowa case studies presented in this report will be used to develop access management education materials for Iowa transportation professionals and other audiences interested in the impacts of access management
Iowa's Mississippi River Trail plan by David Plazak( Book )

2 editions published in 2003 in English and held by 14 WorldCat member libraries worldwide

The Mississippi River Trail (MRT) is a world-class bicycle trail that will follow the Mississippi River all the way from its headwaters in Minnesota to the Gulf of Mexico. The trail is partially completed; much of it is still in the planning and development stages. When complete, the MRT will Link over 2,000 miles of recreational trails through 10 states, including 280 miles in Iowa. Designated as a National Millennium Trail, the MRT will preserve natural environments along the river, stimulate economic growth in river communities, and provide bicyclists access to a variety of landscapes, history, and culture. The Iowa Department of Transportation commissioned the Center for Transportation Research and Education at Iowa State University to develop a plan for a safe, economically beneficial, and scenic MRT route through Iowa. This report presents the MRT plan for Iowa. It is organized in the following chapters: Executive Summary; (1) Introduction - vision statement and objectives; (2) Iowa MRT Minimum Design Standards; (3) Iowa MRT Route Analysis; (4) Recommended Improvement Plan; (5) MRT Implementation; and (6) Estimated Benefits and Impacts of the Iowa MRT. Additional information is provided in the following appendices: (A) GIS Analysis for the MRT; (B) Iowa MRT Maps; (C) Public Input; (D) Public Comments; and (E) References

Process to identify high-priority corridors for access management near large urban areas in Iowa by David Plazak( Book )

2 editions published in 2002 in English and held by 11 WorldCat member libraries worldwide

This research project was intended to produce a strategy for addressing current and future access management problems on state highway routes located just outside urban areas that serve as major routes for commuting into and out of major employment centers in Iowa. There were two basic goals: (1) to develop a ranking system for identifying high-priority segments for access management treatments on primary highways outside metro and urban areas and (2) to focus efforts on routes that are major commuting routes at present and in the future. The project focused on four-lane expressways and two-lane arterials most likely to serve extensive commuter traffic. Available spatial and statistical data were used to identify existing and possible future problem corridors with respect to access management. The research team developed a scheme for ranking commuter routes based on their need for attention to access management. This project was able to produce rankings for corridors based on a variety of factors, including proportion of crashes that appear to be access-related, severity of those crashes, and potential for improvement along corridors. Frequency and loss were found to be highly rank correlated; because of this, these indicators were not used together in developing final priority rankings. Most of the highest ranked routes are on two-lane rural cross sections, but a few are four-lane expressways with at-grade private driveways and public road intersections. The most important conclusion of the ranking system is that many of the poor-performing corridors are located in a single Iowa Department of Transportation district near two urban areas--Des Moines and Ames. A comprehensive approach to managing access along commuting corridors should be developed first in this district since the potential benefits would be highest in that region
Performance measures for Iowa transportation systems by David Plazak( Book )

3 editions published in 2006 in English and held by 11 WorldCat member libraries worldwide

The purpose of performance measures in planning operations is to identify and track meaningful, quantifiable measures that reflect progress toward the goals of the plan. The Iowa Department of Transportation (DOT) has already adopted performance measures in a number of operational areas, including highway maintenance, highway safety, public transportation, and aeronautics. This report is an initial effort to utilize performance measures for transportation system planning. The selected measures provide a cross-section of system performance indicators across three selected transportation planning goals (safety, efficiency, and quality of life) and five transportation modes (highway/bridge, public transit, railroads, aviation, and pedestrian/bicycle). These performance measures are exploratory in nature, and constitute a first attempt to apply performance measures in the context of a statewide multimodal transportation plan from the Iowa DOT. As such, the set of performance measures that the Iowa DOT uses for planning will change over time as more is learned about the application of such measures. The performance measures in this document were developed through consultation with Iowa DOT modal staff (aviation, railroads, highways, public transportation, and pedestrian/bicycle) and the Office of Traffic and Safety. In addition, faculty and staff at the Iowa State University Center for Transportation Research and Education were consulted about performance measurement and data within their areas of expertise
Development of a transportation and land use public policy education program for Iowa( Book )

1 edition published in 2000 in English and held by 10 WorldCat member libraries worldwide

This literature review serves as a foundation for a transportation and land use public policy education program for Iowa. The objective of the review is to summarize relevant research findings, to review the state of practice and policies of other state and local governments, and to explore land use trends both within the state of Iowa and the nation as a whole. Much of what we learned has been incorporated into the course materials. Because we expect to identify more useful sources throughout the project, this literature review should be considered a work in progress

The purpose of the study was to review Iowa's public policy issues related to the state provision of overnight commercial truck parking and to make recommendations regarding the same. It was decided to limit the research and data gathering to a study of national trends in public commercial truck parking at facilities along and adjacent to Iowa's interstate highways
Access management : a review of recent literature( Book )

2 editions published in 1996 in English and held by 8 WorldCat member libraries worldwide

The Iowa Department of Transportation's Access Management Task Force was established as part of the Iowa Department of Transportation's overall Safety Management System (SMS) effort. The goal of the Access Management Task Force is to develop a program designed to educate and market the concept and benefits of access management to landowners and developers, professional planners and engineers, planning and zoning staff members, appointed and elected officials, and motorists. Access management is pursued through the design and control of driveways, curb cuts, turning movements, interior circulation of parking lots, and public street connections and intersections. Usually, state highways or major urban and suburban arterial streets are the targets of access management projects. Access management is also a concern on main county roads when there is a transition from a rural environment to a town or city
Access management research and awareness program( Book )

2 editions published in 1999 in English and held by 7 WorldCat member libraries worldwide

Access management involves balancing the dual roles that roadways must play - through travel and access to property and economic activity. When these roles are not in proper balance, the result is a roadway system that functions sub-optimally. Arterial routes that have a too high driveway density and provide overly extensive access to property have high crash rates and begin to suffer in terms of traffic operations. Such routes become congested, delays increase, and mean travel speeds decline. The Iowa access management research and awareness project has had four distinct phases. Phase I involved a detailed review of the extensive national access management literature so lessons learned elsewhere could be applied in Iowa. In Phase II original case study research was conducted in Iowa. Phase III of the project concentrated on outreach and education about access management. Phase IV of the Iowa access management project extended the work conducted during Phases II and III. The main work products for Phase IV were as follows: 1) three additional before and after case studies, illustrating the impacts of various access management treatments on traffic safety, traffic operations, and business vitality; 2) an access management handbook aimed primarily at local governments in Iowa; 3) a modular access management toolkit with brief descriptions of various access management treatments and considerations; and 4) an extensive outreach plan aimed at getting the results of Phases I through IV of the project out to diverse audiences in Iowa and elsewhere
Development of the Des Moines access management plan by David Plazak( Book )

1 edition published in 2004 in English and held by 7 WorldCat member libraries worldwide

According to Iowa crash records, almost 10% of all crashes in Iowa occur at commercial driveways. Most of these crashes occur on arterials within municipalities. In recent years, nearly a quarter of these crashes have occurred in the Des Moines metropolitan area. This makes the Des Moines metropolitan area a prime candidate for improved access management. Case study research in Iowa has shown that access management is an extremely effective highway safety tool - well-managed routes are, on average, 40% safer than poorly managed routes. The Des Moines metropolitan area has many miles of four-lane, undivided arterials constructed when less was known about the importance of managing access to adjacent land development. This project involved a cooperative effort of the Des Moines Area Metropolitan Planning Organization (Des Moines Area MPO) and the Center for Transportation Research and Education (CTRE) at Iowa State University to develop a comprehensive access management study and program for the Des Moines metropolitan area. The goal of the study is to use the knowledge developed to make improvements that will reduce access-related crashes. It is also anticipated that this project will help local officials make better decisions about access management so that future safety and operational problems can be avoided

Infrastructure management system project report by Tom Maze( Book )

1 edition published in 1998 in English and held by 1 WorldCat member library worldwide

A geographic information system (GIS) is a technology that combines database management with digital mapping on a computer (Korte 1994). Users are able to query the database and have the results displayed on a map or obtain detailed information about objects displayed on a map or obtain detailed information about objects displayed on a map with the click of a mouse button. Relationships between different types of data can easily be understood, displayed, and analyzed with GIS. Useful maps can be printed out or saved for later use. GIS technology has been dropping in price and increasing in ease of use and is now used by many organizations. The project documented in this report developed and pilot tested an infrastructure management information system (IMIS) for two key "traditional infrastructure" systems in Iowa -- sanitary sewer and water supply and distribution systems. The main goal of this project was to develop an effective and useful infrastructure management information system for infrastructure funding organizations, economic developers, and environmental regulators. The project used GIS technology to make the management information as useful as possible for decision makers. The project established a new partnership by combining financial resources from the U.S. Department of Commerce Economic Development Administration (EDA) 302A program, the administrative assistance of the Iowa Department of Economic Development, technological expertise of the Center for Transportation Research and Education (CTRE) at Iowa State University, and the management information of state government and regional planning/development organizations in rural Iowa
