Examination of the Michigan 2010 motor vehicle traffic crash fatality increase
In 2010, national fatal crash counts went down by 3.5%, following on the heels of substantial drops in 2008 and 2009. However, in Michigan, fatal crashes were down substantially in 2009, but up by nearly 8% in 2010. This report contains an in-depth look at the patterns associated with Michigan-s...
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...
The relative odds of involvement in seven crash configurations by driver age and sex
Introduction: Much is known about sex and age differences in collision types, but most studies have examined the effect of declining physical and mental capabilities on older drivers- performance. Fewer studies have focused on the relationship between younger driver-s sex and crash type, and these...
Evaluation of 2010 Delaware crash data reported to the MCMIS crash file
This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that...
Road safety in New York and Los Angeles U.S. megacities compared with the nation.
This study examined road safety in the two U.S. megacities, New York and Los Angeles. Patterns of fatal and all crashes in these megacities were compared with those for the entire U.S. (Also included were data for the two respective states, New York and California.) The data on fatal crashes came...
Road safety in the United States are the (relatively) good times over?.
From 2005 to 2011, we have witnessed an unprecedented trend: Road fatalities in the U.S. have dropped by 26%. However, there are some indications that a reversal of this trend might be beginning to take place. This brief note argues that the economic downturn contributed substantially to the large...
Bus operator types and driver factors in fatal bus crashes results from the buses involved in fatal accidents survey.
The Transportation Safety Analysis Division at the University of Michigan Transportation Research Institute (UMTRI) initiated the Buses Involved in Fatal Accidents (BIFA) project in 2000 to collect more detailed information about buses involved in fatal crashes. The BIFA project is supported by the...
