Item An Examination of the Potential to Reduce the Cost of an Underground LRT Alignment through Geologic Planning and Technological Innovation: Phase I(1987-09) American Underground-Space AssociationThe question of whether Twin Cities Metropolitan Region transportation needs should be served by fixed rail transit has been debated for many years. It appears that the issue may be approaching resolution as a result of the formation of the Regional Transit Board (RTB) and recent activity on the part of Hennepin County in forming a Regional Rail Authority and moving ahead with planning activity. Some important questions about light rail (LRT), such as the capacity of the system, are being answered, but others are not resolved. One of these is whether to site portions of a light rail system underground. While many decisionmakers endorse the worth of an underground alignment in at least the most densely developed urban areas, the cost versus benefit to construct underground versus a surface alignment has been an important factor.Item Urban Congestion Reduction for Energy Conservation: Control Strategies for Urban Street Systems: A State of the Art: Final Report(1988-01) Hajjiri, Samir A.; Stephanedes, Yorgos J.The primary objective of this study is to acquire an understanding of the current state-of-the-art of traffic signal control strategies at urban street systems. Control of traffic signals is by far the most common type of control at heavily trafficked intersections in urban areas. Inefficient use of the transportation system results when traffic signals are set without the aim of optimizing them. The byproducts of such situations include greater fuel consumption, increased vehicle emissions, increased travel time, higher accident rate, and less reliable services.Item Urban Traffic Monitoring, Navigation, and Guidance to Alleviate Urban Traffic Congestion(1988-03) Chang, Kui-Kuo; Stephanedes, Yorgos J.Traffic congestion in urban area seems to be rapidly spreading in space and in time. A few years ago, roads surrounded the central business district of any metropolitan areas had hardly any traffic at all. But now, thousands of commuters crowd in there and try to find shortcuts from their suburban homes to their suburban office destinations. Traffic congestion is spreading to the entire highway network instead of the main radial corridors from downtown. Similarly, the traditional rush hours during the morning and afternoon in the urban area disappeared and have been replaced by a high plateau rush hour which continues from early morning to evening.Item Transportation and Economic Development(1988-07) Stephanedes, Yorgos J.This report summarizes the results of a project undertaken by a University of Minnesota team for the Minnesota Department of Transportation (Minnesota DOT) to determine the existence and extent of relationships between transportation and economic development (in particular, employment) in Minnesota. The interdisciplinary team was directed by the Department of Civil & Mineral Engineering and included experts from Civil & Mineral Engineering, Geography, Economics (both Twin Cities and Duluth campuses), Applied & Agricultural Economics, Industrial Engineering & Operations Research, and Regional Economics.Item CTS Report (August 1988)(Center for Transportation Studies University of Minnesota, 1988-08) Center for Transportation StudiesArticles in this issue: First Monthly Report; Establishment of the Center; Interim Advisory Committee; Committee report mailing; Communication efforts; Multiple disciplines involved; Partnership with Logistics; Pavement Engineering Professor hired; University participating in Airport Study; National HOV facilities conference in October; Sixth Annual conference on Great Lakes Ports and Shipping; Research proposal on Snow Plowing and Blowing Snow Control; Transit Research Proposal; Additional Oil overcharge fundsItem CTS Report (September 1988)(Center for Transportation Studies University of Minnesota, 1988-09) Center for Transportation StudiesArticles in this issue: Work Program for Fiscal year 1989; Permanent Advisory Board; Survey Results; Center mailing list; Transportation Library; Faculty on Airport Expert Panel; Video Technology for Traffic management; Funding from Federal research programs; LCMR Transportation Research; Cold weather research; URISA addresses Transportation Information Systems; Upcoming Transportation eventsItem Case Study: Downtown Seattle Transit Project(1988-09) Center for Transportation StudiesThe Downtown Seattle Transit Project is a $412 million construction project undertaken by Seattle Metro, which centers on a 1.3 mile-long tunnel under downtown Seattle.

Prior to seeking improvement of transit operations and the attractiveness of public travel, the problems of the transit industry had to be clearly defined. To that effect, an initial set of eight problem areas was defined and prioritized on the basis of short- and long-term by a group of local experts. However, as seeking solution to all the problems hence defined would be a most demanding task, it was desirable to reduce the set to a more manageable size that included the problems that were well defined, important, feasible and desirable for analysis and solution in Minnesota and elsewhere. To conduct this analysis, a well known and proven methodology, the Delphi Technique, was used. The findings of the Delphi procedure indicate a prioritization that is, in principle, different from what was initially suggested by the group of local experts. Both groups - the Delphi participants and the local experts ? did concur on the ratings of a few problems (e.g., EFFECT OF COLD CLIMATE). The results of the Delphi procedure and the suggested prioritization of the local experts are exhibited on the following page.Item Center for Transportation Studies Annual Report 1989(Center for Transportation Studies, University of Minnesota, 1989) Center for Transportation StudiesThis publication contains highlights of transportation research, education, and outreach activities conducted by the Center for Transportation Studies and its affiliated programs for the period July 1988 through June 1989 (fiscal year 1989).Item CTS Report (January 1989)(Center for Transportation Studies, University of Minnesota, 1989-01) Center for Transportation StudiesArticles in this issue: Elizabeth Deakin is Winter speaker; Advisory board meetings scheduled for this winter; Traffic signal proposal for counties and cities; Students to TRB conference; Freeway operations conference in June; Diesel engine research funded; Air travel and transit research papers published; Light rail transit planning; Center's outreach activities; Upcoming Transportation eventsItem CTS Report (February 1989)(Center for Transportation Studies, University of Minnesota, 1989-02) Center for Transportation StudiesArticles in this issue: Advisroy board meets for the first time; Pikarsky speaks on transportation challenges; Executive committee begins planning future directions; FAA researchers visit University; Interviews begin for transportation faculty position; Steve Keefe speaks on airport study; Center assists MnDOT's recruiting efforts; David Newcomb receives TRB award; University presentation at TRB; ARTBA student proposals requested; Upcoming transportation eventsItem CTS Report (March 1989)(Center for Transportation Studies, University of Minnesota, 1989-03) Center for Transportation StudiesArticles in this issue: 170 people attend Deakin Luncheon; California investigates Minnesota Tax-sharing; Advisory board will discuss transportation issues; Conference on advanced technologies in transportation engineering; Federal research funds available for second year; Timber bridge proposal; Transit laboratory project; Donald Harper receives award; Underground space center research for MnDOT; Mobility 2000 workshop; Art, architecture, and engineering conference; Editor joins Center Staff; Upcoming Transportation eventsItem CTS Report (April 1989)(Center for Transportation Studies, University of Minnesota, 1989-04) Center for Transportation StudiesArticles in this issue: Robert Ervin is Spring speaker; Advisory board identifies research priorities; Academic leaders address advisory board; CME career development: a student hiring program; Transportation study board presentation; Travel inventory and forecasting projects; Faculty participating in airport issues; MnDOT involves school of management; Soil water research for pavements presented; Spain shows interest in traffic video detection system; Upcoming transportation eventsItem CTS Report (May 1989)(Center for Transportation Studies, University of Minnesota, 1989-05) Center for Transportation StudiesArticles in this issue: Center issues request for proposals; Executive committee will select projects; Faculty invited to meeting about Center; Executive committee established annual cycle; CTS will sponsor annual research conference; Students hear MnDOT presentations; Transportation plays major role in art, architecture, and engineering conference; Bridge design is topic of research proposal and paper; Transportation paper presented at Geographers conference; Aircraft noise research paper published; Matthew Huber receives award; University students receive transportation scholarships; Upcoming Transportation eventsItem Transportation of Energy in Minnesota: Review and Analysis(1989-06) Harper, Donald V.The purpose of the study reported on here was to investigate and analyze the energy transportation system in Minnesota in order to identify what the system consists of and how energy sources' are transported to and within the state, and to evaluate the system and to make recommendations for state policy on the matter.
