OTREC-RR-11-12 By Kathleen Harder et al.
eBook (PDF): $0.00
Travel-time variability is a factor in network performance. It measures the time uncertainty for users moving between two nodes in a network. The importance of the time variance depends on the user... More > penalties. In road networks, travelers consider this uncertainty in their route selection. This complex decision is based not only on the attributes, but also on the traveler’s previous experience. Over the past several years, the analysis of these behavioral responses to fluctuations in travel-time variability has become a central topic in transportation research. These are generally based on theoretical approaches using Wardropian equilibrium or empirical formulations using Random Utility Theory. This report focuses on the travel behavior of commuters using Interstate 394 and the choices of commuters crossing the Mississippi River in Minneapolis. Inferences are based on GPS tracking data and surveys. Two distinct approaches are used to analyze the behavioral responses of two distinct sets of subjects.< Less
OTREC-RR-12-02 By Karen Dixon et al.
eBook (PDF): $0.00
The Highway Safety Manual (HSM) published by the American Association of State Highway and Transportation Officials in the spring of 2010 includes safety predictive methods which are used to estimate... More > the safety of a transportation facility. However, the safety performance functions (SPFs) were developed for states other than Oregon. Because of differences in crash reporting, driver and animal populations, and weather conditions, officials need calibrated SPFs for Oregon facilities. Predictive methods were developed for rural two-lane roads, rural multilane roads, and urban/suburban arterial roads. In this project SPFs were calibrated for these facility types based on their historic performance in Oregon. The report illustrates methods of site selection, collection of crash and site data, analysis methods, and an evaluation of crash severity distribution methods. Oregon agencies can use calibrated HSM predictive methods to more accurately assess expected facility safety performance for Oregon conditions.< Less
