3702 Alaska Bridge Bent Pushover Software Including Concrete Confinement Effects
Software for the pushover analysis of Alaska-style bridge bents will be developed for this project. Freely available software libraries will be utilized in the software development. A graphical user interface will be created from the OpenGL graphical library, while the modules for nonlinear structural analysis will be created using OpenSees, an open sources finite element software framework. It is anticipated that the proposed software will significantly reduce the cost and time spent designing Alaska-style bridges to new displacement-based American Association of State Highway and Transportation Officials (AASHTO) seismic guidelines. Currently, engineers use disparate computer programs, making the design of new bridges time consuming. The socio-economic benefits derived from the software will be felt by all residents of Alaska in the form of better and more cost-effective bridges designs.

3922 Roadway Weather Information System and Automatic Vehicle Location (AVL) Coordination
Along with impaired driving and speeding, inclement weather is a major cause of vehicle accidents on roadways. In particular, winter storms are a frequent emergency that must dealt with by the Oklahoma Department of Transportation (ODOT), the Department of Public Safety and local municipalities. Response to weather conditions involves the use numerous vehicles statewide, including snow plows and spreader trucks. These trucks can utilize a variety of chemicals which can increase traction on the roadways and reduce the potential for the precipitation to form solid ice on the treated roads. Such chemicals include sand and salts. <br><br> The application of chemicals is necessary to maximize traffic safety in the worst winter weather conditions. However, these chemicals not only negative environmental impacts, they also take their toll on the pavement and bridges on which they are applied. They accelerate corrosion and increase the frequency of required pavement and bridge maintenance. It is desirable to effectively use the resources available to state and local transportation-related agencies in order to both improve public safety on highways and roadways, and to reduce any needless impact the application of winter weather chemicals causes on pavement and bridges. <br><br>This research project will propose the development of an intelligent winter weather vehicle monitoring system that integrates automatic vehicle location (AVL) information from relevant vehicles with information regarding where and which chemicals have been recently applied. This information will also be integrated with weather sensor data from ODOT pavement and bridge sensors as well as other weather information including date from the Oklahoma Mesonet. This information will allow for improved monitoring of road conditions across the state and improved coordination and deployment of relevant vehicles. By maximizing the application of winter weather techniques (including the application of chemicals) to areas in which conditions pose the highest risk of accidents, traveler safety can be improved while at the same time, the destructive impacts of these techniques can be applied less frequently to pavement and bridges in areas in which conditions pose a lower risk. As the nature of bridges lends themselves to increased likelihood of icing, these locations will be a particular focus of this work. Using the system to monitoring surface conditions on bridges will indicate when these structure need to be more frequently treated relative to other paved roadways. <br><br> This system will be developed within the University of Oklahoma Intelligent Transportation Lab. The system will integrate data from ODOT and will be made available to dispatchers and policy makers at that agency. Once developed, it may be possible to integrate data from individual municipalities in the state and make the system available to relevant local agencies to improve state and local coordination during weather emergencies.<br><br>

4142 Greenroads: Application and Evaluation
Greenroads is a sustainability rating system for roadways. It is being developed at the University of Washington (UW) under 3 different projects, one of which is funded by TransNow from 2007-2009. CH2M HILL is a partner in this development and has contributed their own internal funds and time in a process completely separate from UW funding. Detailed Greenroads information can be found at: As Greenroads version 1.0 nears completion, the next phase of this project is to investigate its use and impact on actual roadway projects. This involves partnering with owner agencies and consultants to select ?pilot projects? that will intentionally pursue a Greenroads rating certification level and actively use the rating system to influence the design and construction phases of a roadway project. The Greenroads team, in conjunction with these partners will evaluate the following: (1) feasibility of using the system, (2) potential modifications to the rating system based on use, (3) potential for formal adoption by pilot project partners, (4) initial and life cycle cost impacts of a Greenroad, and (5) workflow of project application, review and certification. The end goal is to have Greenroads be the roadway rating system of choice in the U.S. This research will be divided into two parts: Part 1 will obtain pilot project commitments from partners and apply Greenroads in the design phase, and Part 2 will apply Greenroads in the construction phase and fully assess project impacts once the pilot projects are complete. UW has identified the Oregon Department of Transportation (ODOT), Western Federal Lands Highway Division, Perteet Inc., PB World, and Triad Development as potential partners for pilot projects.

5747 Changing Economy, Demographics, Land Use, Transportation Policies and their Impacts on Travel Behavior
Facing major challenges relating to energy consumption, global warming, environmental quality, and economic viability, metropolitan regions around the world are examining the consequences of alternative growth patterns on resource consumption. As agencies plan for new land use policies and investments in the transportation system over the next decade, they will face a new set of challenges tied to the changing demographic and economic conditions in Ohio, in addition to the rising costs of energy and related policies aimed at reducing the carbon footprint of our economy. The first step in understanding the possible implications of these changes is a deeper understanding of the current relationships between land use and travel behavior, and how these might be impacted by future land use, transportation and energy policies.

5757 Green Noise Wall Construction and Evaluation
The Ohio Department of Transportation (ODOT) is required to consider noise abatement for projects funded through Federal Highway Administration (FHWA) and ODOT has developed a noise abatement policy. Executive Leadership has charged the Department with incorporating green alternatives in construction, design, and mitigation of impacts to roadway projects in accordance with ODOT's 2010-2011 Business Plan, Initiative 6, "Go with Green." With regard to the environmental mitigation of highway projects, a green noise wall was selected for evaluation and assessment as a pilot/experimental option to reduce traffic noise. The objective of this project is to evaluate the feasibility of construction of this type of wall in terms of structural integrity, plant sustainability, acoustic protection, geotechnical stability, construction costs, and maintenance costs and concerns.

5953 Decision-Support Framework for Quantifying The Most Economical Incentive/Disincentive Dollar Amounts for Critical Highway Pavement Rehabilitation Projects
In an effort to motivate contractors to complete construction projects early on high-impact highway pavement construction projects, state transportation agencies (STAs) including the Texas Department of Transportation (TxDOT) have often used incentive/disincentive (I/D) contracts. However, determining I/D rates is extremely difficult due largely to the lack of systematic methods for helping STAs determine effective I/D rates. The primary goal of this project is to develop a novel framework for determining the most realistic and economical I/D dollar amounts for high-impact highway improvement projects. To achieve its goal, this project proposes an integration analysis including project schedule and the lower and upper bounds of the I/D contract. The lower bound is the contractors additional cost of acceleration, and the upper is the total savings to road users and to the agency. This project will provide the research community with the first view and systematic estimation method that STAs can use to determine the most economical and realistic I/D dollar amount for a given projectan optimal value that allows the agency to stay within budget while effectively motivating contractors to complete projects ahead of schedule. It will also significantly reduce the agencys expenses in the time and effort required for determining I/D dollar amounts.
