      <title>THE IOWA GRAIN FLOW SURVEY: WHERE AND HOW IOWA GRAIN PRODUCERS SHIP CORN AND SOYBEANS</title>
      <link>https://trid.trb.org/View/462036</link>
      <description><![CDATA[To provide information on Iowa grain producer flows, Iowa State University, the Iowa Department of Transportation, the Iowa Department of Agriculture and Land Stewardship, and the Iowa Agricultural Statistics cooperatively conducted a survey of how and where Iowa grain producers ship their 1994-95 corn and soybean sales. The producer grain flow survey data were collected by questionnaire from a random sample of farm operators maintained by the Iowa Agricultural Statistics. the 3,501 questionnaires were mailed by Iowa Agriculture Statistics on August 17, 1995. The single mailing yielded 1,510 useable responses; 42.8 percent of those sampled returned useable questionnaires.]]></description>

      <title>AUTOMATED METHODS FOR COLLECTING BRIDGE INSPECTION DATA IN THE PONTIS FORMAT</title>
      <link>https://trid.trb.org/View/462037</link>
      <description><![CDATA[This paper briefly introduces the software that was developed for the Iowa DOT to collect bridge inspection data for the Pontis bridge management system. The program's menu-driven format guides the user through the inspection and data entry process. After completing an inspection, the software allows the user to prepare detailed inspection reports. More important, the program can combine into one file the inspection data for different bridges for the use by the Pontis optimization routines to investigate different maintenance activities.]]></description>

      <title>INTERMEDIATE DIAPHRAGM EFFECTS ON THE RESPONSE OF A PRESTRESSED CONCRETE GIRDER BRIDGE TO LATERAL FORCES</title>
      <link>https://trid.trb.org/View/462038</link>
      <description><![CDATA[The main objectives of the research reported in this paper were to investigate the effectiveness of intermediate RC and steel diaphragms in PC, girder-slab bridges that are subjected to lateral load and to determine whether steel diaphragms of some conventional configuration are essentially structurally equivalent to cast-in-place RC diaphragms. The investigation included analytical studies and testing of a full-scale-model, PC, girder-slab bridge.]]></description>

      <title>USE OF EXPERT SYSTEMS FOR ROADWAY WEATHER MAINTENANCE DECISIONS</title>
      <link>https://trid.trb.org/View/462039</link>
      <description><![CDATA[The authors developed expert systems for two specific tasks relating to roadway weather decision making. The first is a system for forecasting frost formation on bridges and roadways in central Iowa, and the second is a system for forecasting fog on US Highway 30 in Cedar Rapids, Iowa, due to plumes emitted by cooling towers at a corn-sweeteners production plant adjacent to the roadway. From these experiences the authors have concluded that expert systems can be useful in roadway weather maintenance decisions. These experiences also have allowed the authors to consider the more general issue of decision making with regard to the use of weather information.]]></description>

      <title>A METHODOLOGY FOR CONDUCTING RESEARCH INTO WINTER HIGHWAY MAINTENANCE</title>
      <link>https://trid.trb.org/View/462040</link>
      <description><![CDATA[A methodology is described whereby the ice scraping performance of cutting edges as a function of their geometry has been measured, first in the laboratory, then in controlled (closed road) field tests, and finally in a limited field deployment. The results of this study have been very promising. However, as important as the specific results have been, perhaps equally as important has been the development of a methodology whereby promising research ideas can be taken from the lab to the field as rapidly (with due care) as possible. Such a rapid research and development methodology can be applied to a number of winter maintenance activities and, no doubt, to other areas as well.]]></description>

      <title>CONCEPTUALIZATION OF THE FUTURE HIGHWAY MAINTENANCE VEHICLE</title>
      <link>https://trid.trb.org/View/462041</link>
      <description><![CDATA[Snow and ice control operations provide an environment that will benefit from utilization of advanced technology. In recognition of this potential, the state DOTs of Iowa, Michigan, and Minnesota have formed a consortium to support a project that will define vehicle and equipment requirements, develop and evaluate a prototype vehicle, and produce vehicles for fleet evaluation. A key element of this project is the inclusion of private sector partners into the consortium. The approach being pursued is defined in three phases: (1) description of the functions and a financial evaluation; (2) prototype development and evaluation; and (3) a comprehensive fleet evaluation. The schedule is to have a prototype vehicle ready for testing during the winter of 1996-97 and fleet vehicles available for the winter of 1997-98.]]></description>

      <title>THE PROCESS IN DEVELOPING INTERMODAL FREIGHT STRATEGIES</title>
      <link>https://trid.trb.org/View/462042</link>
      <description><![CDATA[The economic well being of the Kansas City region depends in great part upon the reliable and efficient movement of freight and goods between producers and markets. To facilitate this movement and to ensure that Kansas City remains a vital transportation hub, local, regional, and state governments in 1994 launched a major study of the area's intermodal resources -- "intermodal" meaning the shipment of freight by various methods of transport, including rail, air, water, and roadway. This study was sparked by the need for the Mid-America Regional Council (MARC) to fully integrate freight considerations into its overall metropolitan transportation planning process, as well as an outgrowth from the Chamber's July 1993 Inland Port/Intermodal Task Force Report, which recommended that industry-specific analysis, trends, and technologies be examined.]]></description>

      <title>AMASCOT: DEMONSTRATING TECHNOLOGY FOR AUTOMATING COLLECTION OF MILEAGE-BY-JURISDICTION DATA FROM COMMERCIAL VEHICLE FUEL TAX AND REGISTRATION FEE APPORTIONMENT</title>
      <link>https://trid.trb.org/View/462044</link>
      <description><![CDATA[This paper summarizes an ITS operational test project investigating an application of Intelligent Transportation Systems (ITS) to Commercial Vehicle Operations (CVO). The U.S. Department of Transportation Federal Highway Administration (FHWA) has undertaken efforts to develop and implement ITS in the U.S. The goals for ITS are to enhance transportation safety and efficiency and reduce the need for new highway construction. ITS applications range from metropolitan traffic management to automated toll collection to commercial vehicle operations. The Automated Mileage and Stateline Operational Test (AMASCOT) was conducted by a partnership that included the Iowa Department of Transportation; Rockwell International Corp.; Rand McNally-TDM, Inc.; Center for Transportation Research and Education; Minnesota Department of Public Safety; the Wisconsin Department of Transportation; the Western Highway Institute/ATA Foundation; the ATA-affiliated state trucking associations in Iowa, Minnesota, and Wisconsin; and the Federal Highway Administration.]]></description>

      <title>APPLICABILITY OF PERFORMANCE-BASED STANDARDS FOR U.S. TRUCK SIZE AND WEIGHT REGULATIONS</title>
      <link>https://trid.trb.org/View/462045</link>
      <description><![CDATA[This paper examines size and weight regulation in 31 industrialized countries to determine how performance standards have been employed, the positive or negative experience with the application of performance-based standards, and methods used to apply and enforce these standards. Similar to the experience of other countries, if the U.S. were to incorporate performance-based standards into federal size and weight regulations, it would probably adopt its own unique path of migration toward standards that are compatible with its own land-based trading partners.]]></description>

      <title>HIGHWAY FINANCE -- ENTERING THE SECOND CENTURY</title>
      <link>https://trid.trb.org/View/462047</link>
      <description><![CDATA[Four findings are evident from the facts and research results reported here: (1) As documented by the 1995 report on conditions and needs, both highways and transit are insufficiently funded to meet requirements of the systems over the next decade. (2) While it will remain a principal revenue source for at least the next two decades, the motor fuel tax faces problems and alternatives to it need to be considered and developed. (3) Use of transportation user fee revenue for non-transportation purposes drains resources at a time when more funding is needed for our highways and transit systems just to maintain current conditions, let alone improve service to the public. (4) Approaches to using existing federal, state, and local funds to leverage additional funding show promise.]]></description>

      <title>DETERMINATION OF A DISCRIMINANT FUNCTION AS A PREDICTION MODEL FOR EFFECTIVENESS OF SPEED ZONING IN URBAN AREAS</title>
      <link>https://trid.trb.org/View/462021</link>
      <description><![CDATA[Speed zoning is the application of a different speed limit to a section of roadway than is applicable to adjoining highway segments. In a 1985 Federal Highway Administration survey of state and local transportation officials, four factors received the highest frequency response as part of their speed zoning procedure. In descending order they are: 85th percentile speed, accidents and pace speed tied for second, type and amount of roadside development was fourth. These four factors are measurable in quantitative units and are utilized by a number of states as part of a procedure to adjust the speed limit. The purpose of this research is to identify additional factors which can be used to determine where speed zoning will be effective and to clarify their relationship to raising or lowering the speed limits. The hypothesis is that a quantifiable relationship exists between accident parameters, speed parameters, roadside friction, and environmental/geometric variables such that it is possible to predict the effectiveness of speed zoning in urban areas.]]></description>

      <title>SOME PERSPECTIVES ON CONGESTION: THE EMERGING MISSION OF MODERN TRANSPORTATION DEPARTMENTS</title>
      <link>https://trid.trb.org/View/462023</link>
      <description><![CDATA[Travel demand in the U.S. continues its steady growth, vastly outstripping the ability of state DOTs and the underlying will of their bodies politic to match this growth with capacity supply. The inevitable result is congestion, which is spreading everywhere in both time and space. A series of national policies and programs have grown up, including congestion management systems, special funding categories, interest in congestion pricing schemes, and the application of advanced technologies such as intelligent transportation systems to deal with this phenomenon. As a result, coping with congestion has emerged as a major mission of a modern state DOT, joining the ranks of the others.]]></description>
