Cruel Seas: World War 2 Merchant Marine-Related Nautical Fiction from the 1930s to Present

Krummes, Daniel C
2015

Cruel Seas is an annotated bibliography of fiction in English that involves civilian steamships of the merchant marine in works set during World War Two (or slightly before). While the subtitle states "1930s to Present," the last entry was added in 2008, and the work will not be updated. The entries include novels, novellas, and short stories, but exclude poetry, theater plays, and fiction written for juveniles (unless the work can appeal to adults as well). Many of the works involve ships in convoy across the Atlantic.An earlier version of Cruel Seas was published in softcover edition in...

Sources of Information in Highways: A Bibliography

Krummes, Daniel C.
Ambler, Betty
Atwood, Paul
Bix, Janet
Clark, Laurel
Gallwey, John
Geary, Kay
Gutshall, Judy
Haake, Susan
Krummes, Daniel
Matis, Lynn

Sweet, Robert
2001

This bibliography, containing over 650 entries, is intended to serve as a guide to the major sources of information on highways. While sources listed focus primarily on the United States and Canada, some international materials have been included. Though emphasis is on current publications, some materials of historical interest have also been included. Resources listed in the bibliography include both print and electronic materials, with many Internet sites falling within that latter category. The bibliography was a collaborative effort and was compiled by twelve members of the...

The Ethical Challenges and Professional Responses of Travel Demand Forecasters

Brinkman, Anthony P.
2003

Thirty years ago scholars first presented convincing evidence that local officials use biased travel demand forecasts to justify decisions based on unstated considerations. Since then, a number of researchers have demonstrated convincingly that such forecasts are systematically optimistic-often wildly so-for reasons that cannot be explained solely by the inherent difficulty of predicting the future. Why do modelers-professional engineers and planners who use quantitative techniques to predict future demand for travel and estimate its potential impact on built and proposed transportation...

Understanding and Mitigating Capacity Reduction at Freeway Bottlenecks

Chung, Koohong
2005

Two freeway bottlenecks, each with a distinct geometry, have been investigated in an effort to understand traffic conditions leading to capacity losses (i.e., breakdown). One bottleneck is formed by a horizontal curve and the other by a reduction in travel lanes. These bottlenecks are shown to exhibit breakdowns after queues form immediately upstream. The vehicle accumulations that arise near these bottlenecks are shown to be good proxies for the mechanisms that trigger breakdowns. Evidence is provided to show that these losses can be recovered, postponed or even avoided entirely by...

Spatial Models of Morning Commute Consistent with Realistic Traffic Behavior

Lago, Alejandro
2003

Urban planners are increasingly concerned about the sprawling suburban development in metropolitan areas around the world, which they often blame for growing traffic congestion and excessive highway investment needs. This dissertation seeks to shed light on this issue by studying the relationship between morning commute congestion and urban form. The causes and consequences of traffic congestion have been extensively studied in the economics and engineering literatures. Unfortunately, most conclusions have been drawn from very idealized models, which either fail to consider adequately the...

Electric Two-Wheelers in China: Analysis ofEnvironmental, Safety, and Mobility Impacts

Cherry, Christopher R.
2007

Electric powered two-wheel bicycles, while extremely popular in China, have been recently banned by policy makers due to safety, congestion, and environmental concerns. This study investigates the tremendous growth of electric two wheel bicycles in China and compares and quantifies their environmental and safety impacts with the impacts of alternative modes of transportation, such as traditional bicycles, public transportation, or personal cars. The research also analyzes the benefits of electric two wheel bicycles, such as increased mobility and access to opportunities. Additionally, the...

Vehicle Reidentification and Travel Time Measurement Using Loop Detector Speed Traps

1998

This dissertation presents a vehicle reidentification algorithm for consecutive detector stations on a freeway, whereby a vehicle measurement made at a downstream detector station is matched with the vehicle’s corresponding measurement at an upstream station. The algorithm should improve freeway surveillance by measuring the actual vehicle travel times; these are simply the differences in the times that each (matched) vehicle arrives to the upstream and downstream stations. Thus, it will be possible to quantify conditions between widely spaced detector stations rather than assuming that...

Deep Discount Group Pass Programs as Instruments for Increasing Transit Revenue and Ridership

Nuworsoo, Cornelius Kofi
2004

Transit properties in the USA have historically experienced loss of market share and low levels of farebox recovery. They resorted to service expansion to maximize subsidies. Experience suggests that: (a) fare increases have not had the desired effect; (b) fare reductions can boost ridership but can also reduce revenue and increase subsidies. The challenge lies with the adoption of such strategies as deep discount group pass programs that can produce more marginal revenue than cost. Deep discount transit pass programs provide groups of people with unlimited-ride transit passes in exchange...

Welfare Analysis of Informal Transit Services in Brazil and the Effects of Regulation

Golub, Aaron David
2003

In Brazil, the recent explosion of informal transport activity is having profound effects on formal, regulated transport systems and is the source of great controversy in the urban passenger transportation arena. A variety of policies are being proposed to manage what has been an uncontrolled growth of the sector. This study seeks to understand the advantages these systems have for users who choose them, and how proposed policies will impact these benefits. A corridor in Rio de Janeiro with substantial informal activity was used as a case study and field trips were made to gather basic...

An Analysis of Port Selection

Malchow, Matthew Brian
2001

The objective of this research is to study the competition among ports. In particular we study the relation between port characteristics and port market share of maritime traffic. Maritime carriers make two primary decisions that affect ports. In the long-term, they assign vessels to routes. In the short-term, they assign each shipment to a vessel and, with that vessel, a port. In this research, we assume that vessel schedules are fixed and model the assignment of shipments as a function of the attributes that describe each port. For a carrier, some assignments are simpler than other...
