showing decreased crash rates. Two of these were statistically significant decreases. None of the increased rates were found to be statistically significant. Next Steps The next step to this research effort is to apply the empirical bayes methodology to the data set utilizing a rural twolane highway safety prediction algorithm. The use of this methodology will correct for regression-to-the-mean bias and improve the precision of the statistical analyses. Posters 638 ICOET 2007 Proceedings
Simulation-Optimization Framework to Support Sustainable Watershed Development by Mimicking the Pre-Development Flow Regime Abstract Dr. Emily Zechman, Research Assistant Professor (919-513-7920, emzechma@ncsu.edu), Department of Civil, Construction, and Environmental Engineering, North Carolina State University, Campus Box 7908, Raleigh, NC 27695-7908, Fax: 919-515-7908 USA A new approach is presented to achieve a more aggressive sustainability objective for designing transportation infrastructure and land use planning: to design BMPs to continuously mimic the natural flow regime and ensure that ecosystems downstream of development would not be adversely affected. As the land uses are changed for development of urban areas and transportation infrastructure, ecosystems in receiving water bodies are significantly affected by the changes in duration, peak, and minimum flows. Though Best Management Practices (BMPs) are typically designed to not exceed some peak flow during a design storm and perhaps maintain a minimum flow at low-flow periods, downstream conditions are altered, potentially harming ecosystems. A new approach is presented to achieve a more aggressive sustainability objective: to design BMPs to continuously mimic the natural flow regime and ensure that ecosystems downstream of development would not be adversely affected. This objective may not be achievable through the implementation of a single detention pond at a watershed outlet; a system of BMPs strategically placed throughout the watershed may be required. Several BMPs exist as options for treatment, such as detention/retention ponds, constructed wetland systems, infiltration systems (i.e., porous pavement), and vegetative filtrations systems. As each system chosen for implementation must be specified by a set of design decisions and placement location, an efficient mechanism of optimization is needed to handle the large array of decisions. In addition, a comprehensive modeling framework is needed to simulate a collection of BMPs simultaneously. A quantitative analysis framework is described and illustrated for coupling BMP and watershed models with optimization techniques. Bridging the Gaps, Naturally 639 Posters
