Summary

This document serves as a newsletter summarizing the activities, priorities, and findings of the Oregon Department of Transportation (ODOT) Research Unit for Spring 2007. It outlines the prioritization of research projects for Fiscal Year 2008, reports on completed studies regarding environmental streamlining, contracting, and water quality, and announces ongoing surveys concerning older drivers. For FY 2008, the ODOT Research Advisory Committee (RAC) prioritized twelve stage-two problem statements to guide future research. These topics include evaluating safety at high-speed signalized intersections, assessing steel anchorage performance, analyzing multi-modal investment criteria, and addressing institutional barriers to incident clearance. The selection process involved sorting approximately 125 initial problem statements into eight subject areas, with final funding decisions coordinated with the Oregon Transportation Research and Education Consortium (OTREC) to maximize resource efficiency. Several completed research projects are detailed. A case study on the State Bridge Delivery Program identified nine key lessons for successful environmental streamlining, emphasizing the need for executive leadership, entrepreneurial staff, and a tiered negotiation process. This program received the FHWA Environmental Excellence Award in 2005. Another project established guidelines for Incentive/Disincentive (I/D) contracting, developing an Excel-based model to determine effective incentive amounts by balancing contractor acceleration costs against public Road User Costs. Additionally, a study on highway stormwater runoff addressed Clean Water Act compliance challenges; it produced a Microsoft Word template for monitoring plans and highlighted the logistical difficulties of sampling dispersed, storm-dependent runoff. The newsletter also highlights ongoing and upcoming initiatives. A statewide mail survey, conducted in cooperation with Portland State University, is examining reasons for driving cessation among elderly Oregonians to inform public transit planning for the aging population. Furthermore, the document lists recently published reports, including studies on tsunami design criteria for coastal infrastructure and a summary of the 2004 Traveler Opinion and Perception Survey. Administrative updates include improved online access to Transportation Research Board journals for ODOT staff and information on the Technology Transfer (T2) Center, which provides technical assistance and training to local governments.

Key finding

The document reports that completed research projects yielded practical tools and insights, such as a model for determining incentive amounts in contracting, a template for stormwater monitoring plans, and lessons learned for implementing environmental streamlining programs.
