Evaluating the Effectiveness of the Safety Investment Program (SIP) Policies for Oregon

Christopher Monsere
Karen Dixon
The Oregon Department of Transportation (ODOT) Safety Investment Program (SIP) seeks to allocate safety funds in a manner that maximizes safety benefits on preservation projects and at specific high-crash locations. The SIP philosophy targets highway sections for investment with the premise that the most effective use of safety dollars to save lives is to invest in areas where the most people are being killed or seriously injured in traffic crashes. The SIP categorizes five-mile roadway secti... Read More

Development of a Model to Predict and Mitigate Environmental and Public Health Impacts of Traffic Flows and Traffic Management Policies in Urban Transportation Microenvironments

Linda George
Christopher Monsere , Miguel Figliozzi
Urban residents spend a considerable amount of time in transportation microenvironments as pedestrians, bicyclists, public transit users, residents and workers situated along roadways, and automobile commuters. Within these microenvironments, vehicles powered by carbon-based fuels (e.g., gasoline, diesel) have a negative impact on air quality. Vehicular exhaust is the source of a multitude of air contaminants, including particulate matter (PM). Particulate matter of concern ranges in size fro... Read More
