Development of warrants for installation of dual right-turn lanes at signalized intersections

Description: "Right-turn lanes provide space for the deceleration and storage of right-turn vehicle, and separate turning vehicles from through movements. Dual right-turn lanes are increasingly used at urban intersections primarily for two reason: (1) to accommodate high right-turn demands and avoid turn-pocket overflows, and/or (2) to prevent right-turn vehicles that exit from a nearby upstream freeway off-ramp (on the left of the roadway) from abruptly changing too many lanes toward the right-turn lane at intersection."

The economic efficiency of allowing longer combination vehicles in Texas

Description: "This paper shows the economic efficiency of allowing longer combination vehicles in Texas. First, an overview of the truck size and weight policies is explained, with an emphasis on those that affect Texas. Next, LCV operations in other countries are described. Then, an LCV scenario for Texas is chosen, with specific routes and vehicle types. Operational costs for these vehicles are calculated on a cost per mile and cost per ton (or cubic yard) mile. The LCV scenario and the current truck base case are analyzed to find the number of truck trips, the number of mile, and the cost per mile for the chosen routes. These are then compared to estimate the change if LCVs were allowed in Texas."

An evaluation of the effects of transit oriented development in a suburban environment

Description: "Transit-Oriented Development (TOD) refers to dense, pedestrian-friendly, livable communities that have good transit as a nucleus. While transit facilities are missing in most suburban towns and the residents are heavily dependent on their vehicles, it is wondered whether residents would take advantage if public facilities were available. This paper presents information about some vital aspects of TOD when viewed in suburban communities."

Export growth, energy costs, and sustainable supply chains

Description: "The report examines sustainable supply chains in North America and the role played by rail inter-modal operations in lowering ten-mile fuel and emission costs. It examines whether current systems favor imports over exports - a current complaint from some shippers - and whether the development of inland inter-modal ports offers a solution to moving future freight into and out of large metropolitan areas."

Fracture properties and fatigue cracking resistance of asphalt binders

Description: "The main objective of this study was to evaluate the inherent fatigue cracking resistance of asphalt binders in the form of a matrix with rigid particle inclusions. The underlying rational for this approach was to subject the binders to a state of stress that is similar to the one in a full asphalt mixture."

High speed rail : a study of international best practices and identification of opportunities in the United States

Description: "In the United States, passenger rail has always been less competitive than in other parts of the world due to a number of factors. Many argue that in order for a passenger rail network to be successful major changes in service improvement have to be implemented to make it more desirable to the user. High-speed rail can offer such service improvement. With the current administration's allocation of $$8 billion in its stimulus package for the development of high-speed rail corridors and a number of regions being interested in venturing into such projects it is important that we understand the factors and regulatory structure that needs to exist in order for passenger railroad to be successful. This study aims to review how foreign countries have developed and their railroad systems to identify key factors that have contributed to its successful implementation. An evaluation of the factors, such as organization structure, operation, administration, development and type of funding, that are common to each of these projects will used as performance measures to identify potential locations and opportunities for high speed rail projects in the U.S. Southwest region."

Hybrid distribution trucks: costs and benefits

Description: "This project evaluated a package delivery truck, beverage delivery truck, and a refuse ruck. The research determined that the additional cost (with current prices) of the hybrid refuse truck was justified, but not for the other two trucks. The social cost of emissions was also estimated to help justify hybrids' implementation. With this information, the rate of hybrid truck adoption was estimated for various policy scenarios. The results indicated that a correctly designed incentive program can greatly increase the rate of hybrid adoption and could be justified by the additional social benefits of emission reduction."

Impacts of pending federal greenhouse gas legislation on the Texas transportation sector

Description: "This 2010 study, funded by the Southwest Region University Transportation Center, assesses current regulatory attempts to mitigate climate change and how such proposed action would impact the Texas transportation sector economically. Social and political trends suggest the United States may soon join other United Nations Framework Convention on Climate Change (UNFCCC) countries in drafting substantive, national climate change policy. After providing a brief overview of past and present climate efforts taken both nationally and internationally, this paper explores different economic solutions to address the externalities of fossil fuel emissions. Alternatives include command-and-control regulation, a carbon tax, and a cap-and-trade program. Several factors, including the difficulty of quantifying and constraining greenhouse gas emissions downstream at the vehicle tailpipe, suggest a carbon tax levied upon upstream refiners is the most promising market-based alternative to reduce carbon emissions within the United States's transportation sector. Texas business leaders and lawmakers have repeatedly voiced their disapproval of mandatory national carbon controls over the past decade. A crucial factor why much of the Lone Star State's populace remains opposed to climate change action is Texas leads the nation's energy industry, which is decidedly fossil-fuel based and therefore carbon intensive. Prevailing thought is a carbon tax would only elevate fuel prices increasing the cost of residential and commercial activity heavily dependent on motor vehicles. This paper articulates how greenhouse gas legislation may financially impact transportation within the Lone Star State and concludes with ways energy and environmental policymakers can build consensus within Texas to address the carbon externality."
