CMISST supports UMTRI’s goal of removing impediments to safe and efficient mobility for individuals in all parts of society and for productive freight vehicles. CMISST provides data related to travel behavior and heavy truck travel. Analyses of these data help us understand what changes have the greatest impact on mobility and heavy-truck capacity.
Elevating Sustainability
CMISST supports UMTRI’s efforts to reduce greenhouse gas emissions from the operation of ground vehicles by an order of magnitude in the next five years. We provide access to data on fuel use, driving behavior, transit use, and heavy truck transport, all of which can be used to better understand how to improve fuel efficiency across the fleet through driver behavior intervention and improvements in routing and load efficiency for heavy trucks. Many of these same data can be used to study the most cost effective ways to encourage vehicle electrification.
Advancing Safety
CMISST supports UMTRI’s strategic goal of working toward an order of magnitude reduction in fatalities and injuries from motor vehicle crashes within the next five years. We provide access to a rich array of crash datasets and other relevant, linkable datasets that can be used to show which crash and injury countermeasures have the greatest benefit in reductions in injuries and fatalities. The results of such analyses help shape public policy and vehicle and roadway design to improve safety.
CMISST Data GUI
The CMISST Data GUI allows users to study and manipulate different datasets, including FARS, NASS, many state crash data sets. FARS 2009 is available as a sample for users who are not yet affiliated with CMISST.
Data Query Tool
The Michigan Crash Facts Data Query Tool allows users to build queries of motor vehicle crashes, then view the results on a map, in a table, or on a graph. Users may also download subsets of the data and the actual (sanitized) police reports. Build a query
FARS Variable History Lookup
The FARS variable history lookup tool tracks changes in the names of variables and their values over time. Currently the tool is populated with information from 1975 through 2009. Try it out

Michigan Crash Fatality Trends
Figure 1. Long-range (left) and recent-years (right) views of Michigan crash fatalities over the last 50 years. The black line shows the year-to-year rise and fall in total fatalities. The green and red lines show two models of the underlying trends.
Figure 1 shows the behavior of Michigan crash fatalities over the time period of 1940 to 2010 (on the left) and focused on 1999-2010 (on the right). The black lines are the observed fatalities for each year while the green line indicates the trend observed over this time period. Looking at the trend line, we can see that 2010 was actually quite close to the expected number of fatalities whereas 2009 is extremely atypical, particularly as the variations from year to year appear to be much smaller in the past decade than in previous decades.

UTMOST
The Unified Theory Mapping Opportunities for Safety Technology (UTMOST) model was developed to aid in visualizing the effects of safety countermeasures and combinations of countermeasures. As UTMOST is updated and expanded, it will be used to identify how safety countermeasures interact, how they affect the crash population, and whether one or more technologies offer the greatest benefit.
