Tatroz Thomas J. Fisher x  \nAbstract  \nEvery year the National Highway Traffic Safety Association (NHTSA) and Insurance Institute for Highway Safety (IIHS) release safety ratings for popular makes and models of vehicles produced. We link these safety ratings with the accident data provided in the National Automotive Sampling System (NASS) General Estimates System (GES). We develop a web-based dashboard to graphically explore the relationship among these datasets. We create a metric that measures average injuries per vehicle per accident and map it to vehicle safety ratings. Our web application allows a user to explore different aspect of accidents (e.g., use of alcohol, speeding, etc.) and compare injuries and safety rating performance based on these conditions. Lastly, our dashboard allows a user to see differences between the NHTSA and IIHS ratings systems and how they correspond to the data in NASS GES.  \nKey Words: Accident Data, Dashboard, Vehicle Safety Ratings.  \n1. Introduction  \nThe National Highway Traffic Safety Administration (NHTSA) is a federal agency part of the Department of Transportation tasked with saving lives, preventing injuries and reducing vehicle-related crashes; see NHTSA (2016c) . Each year, the National Automotive Sampling System (NASS) collects vehicle accident data from police reports nation-wide. In particular, the General Estimates System (GES) within NASS records data from a nationally representative sample of police reported motor vehicle crashes of all types, from minor to fatal; see NHTSA (2016b) . Since its inception in 1988, the GES has created a database of nearly 30 years of motor-vehicle accident data including variables on vehicles parameters, personal injuries, and environmental conditions. The GES is similar to the well-known Fatality Analysis Reporting System (FARS) data but includes all levels of vehicle accidents.  \nData in the GES is sampled from police accident reports that involve at least one motor vehicle traveling on a traffic way, and the result of the accident must be property damage, injury, or death. The accident reports are sampled from 60 areas that reflect the geography, roadway mileage, population, and traffic density of the United States. Approximately 50,000 police accident reports are collected each year and included in GES. The raw GES data are available: [ftp://ftp.nhtsa.dot.gov/GES/](ftp://ftp.nhtsa.dot.gov/GES/) .  \nVehicle safety is a primary criterion for many when purchasing a new car. Since 1978, the NHTSA has implemented the so-called “5-Star Safety Ratings Program” for motor-vehicles, wherein vehicles undergo a series of crash-safety tests and are assigned a qualitative measure of safety (1  \n􀀃 Corresponding author Cody Philips is a Senior Undergraduate Student in Mathematics & Statistics with an Analytics Co-Major at Miami University, contact information: Department of Statistics, Miami University, 311 Upham Hall, Oxford, OH 45056 USA, Tel: 1-513-529-7828, Fax: 1-513-529-0989, Email: [philipcr@miamioh.edu](philipcr@miamioh.edu)  \n[y](y Robert Garrett is a Sophomore Undergraduate student in Mathematics & Statistics with an Analytics Co-Major at)[ Robert Garrett is a Sophomore Undergraduate student in Mathematics & Statistics with an Analytics Co-Major at](y Robert Garrett is a Sophomore Undergraduate student in Mathematics & Statistics with an Analytics Co-Major at)[ ](y Robert Garrett is a Sophomore Undergraduate student in Mathematics & Statistics with an Analytics Co-Major at)Miami University, Email: [garretrc@miamioh.edu](garretrc@miamioh.edu)  \nzA.J.
