Profile analysis of the LTPP SPS-6 site in Arizona
This report characterizes the longitudinal profiles of five pavement sections within the Arizona Specific Pavement Studies 6 project throughout their service life. This project was built and monitored as part of the Long-Term Pavement Performance Study. Road profile measurements were collected on...
Using naturalistic driving data to assess variations in fuel efficiency among individual drivers
Fuel consumption rates were studied from a naturalistic driving data set employing a fleet of identical passenger vehicles with gasoline engines and automatic transmissions. One hundred and seventeen drivers traveled a total of over 342,000 kilometers (213,000 miles), unsupervised, using one of the...

Finite element modeling of static tire enveloping characteristics
To investigate static tire enveloping characteristics, a three dimensional (3-D) finite element model is proposed. The vertical stiffness of the tire is studied on a flat surface with and without cleat. Tire rubber materials and cord layers are represented independently using -rebar- elements...

Integrated vehicle-based safety systems field operational test final program report.
This document presents results from the light-vehicle and heavy-truck field operational tests performed as part of the Integrated Vehicle-Based Safety Systems (IVBSS) program. The findings are the result of analyses performed by the University of Michigan Transportation Research Institute to...
Development of analysis methods using recent data a multivariate analysis of crash and naturalistic event data in relation to highway factors using the GIS framework.
This report documents and presents the results of a preliminary study into the use and validation of crash surrogates, to be obtained from naturalistic driving studies for the detailed analysis of risk factors. The approach is based on a unified statistical analysis of crash data and surrogate...
Analysis of crash rates and surrogate events Unified Approach.
A preliminary study was done into the use and validation of crash surrogates, which are obtained from naturalistic driving studies for the detailed analysis of risk factors. The approach is based on a unified statistical analysis of crash data and surrogate events that uses a spatial referencing...
