Book Description
This document consists of three sections, each with its own table of contents and independent numbering. Part I, Operational Analysis of Collector-Distributor Systems, develops a procedure for capacity analysis of Collector-Distributor (C-D) roads between successive interchanges. The description of the capacity analysis procedure generally follows the 1985 Highway Capacity Manual procedures; however, a new procedure developed in July 1990 at the University of California, Berkeley, is used for the weaving sections. There is a completed example of the entire procedure for the existing Roe-Nall and the once-proposed braided ramp systems on I-435 in Johnson County, Kansas. This study also identified problems at the merge/diverge areas of the system as a result of "the concentration of two freeway diverging flows at one off-ramp junction, and the accumulation of two C-D merging flows at one on-ramp junction". Configuration changes such as the addition of an auxiliary lane at the merge location and a second off-ramp between the interchanges for the diverge area, were also analyzed for comparative purposes. Part II, Operational Analysis of the Full Cloverleaf Interchange Equipped with Collector-Distributor Roads, describes the advantages of the C-D interchange, a methodology to analyze the interchange, and some of the problems associated with the analysis. The study demonstrates the analysis procedure and reveals that the merge and diverge points become problem areas of the interchange when C-D roads are added. Therefore, the improvements made by moving the weaving area off the mainline should be compared to the decreased level of service at the merge/diverge areas. The study recommends auxiliary lanes for both the merge and diverge areas when C-D interchanges are being considered. Part III is the Technical Appendix for Part II

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Description
This report examines the economics of community-scale solar systems that incorporate a centralized annual cycle thermal energy storage (ACTES) coupled to a distribution system. Systems were sized for three housing configurations: single-unit dwellings, 10-unit, and 200-unit apartment complexes in 50-, 200-, 400-, and 1000-unit communities in 10 geographic locations in the United States. Thermal energy is stored in large, constructed, underground tanks. Costs were assigned to each component of every system in order to allow calculation of total costs. Results are presented as normalized system costs per unit of heat delivered per building unit.

Book Description
Provided is an overview of the Nation's transportation system which identifies future investments required to maintain and develop its infrastructure. The contents of this study were used in support of the National Transportation Policy Statement, issued by the Department of Transportation during March 1990. It is organized around a framework in which transportation is viewed as an integral part of our socioeconomic system. The future development of transportation will be influenced by the same factors affecting the rest of the system, namely, demographic changes, the future course of the economy, the energy supply, and preservation of the environment.
