Released/updated on: 2006-05-18
Geographic coverage: United States
This special topic poll, conducted January 26-31, 2005, was undertaken to assess public opinion about traffic. After first being asked their opinion of how President Bush was handling his term in office, respondents were queried about how often they traveled by car, traffic conditions in their area, and the availability and quality of public transportation and whether or not they used it. The survey also asked questions about respondents' commutes, opinions about traffic congestion, and possible measures to reduce congestion, such as tolls, high occupancy vehicle lanes, building new roads, better timing of traffic lights, carpools, and higher gas taxes. Respondents were also asked about air pollution from cars, how driving made them feel, how often they or others were guilty of speeding, not paying attention, being aggressive, and road rage. Other questions pertained to respondents' opinions of the greatest dangers to safety, how they passed time in traffic, and what type of vehicle they drove as well as their opinion of it. Demographic information included the number of licensed drivers and automobiles in their household, political orientation, education, age, marital status, number of children, Hispanic origin, ethnicity, income, and sex.

Access to Justice in Ontario, 1985-1988 (ICPSR 9729)
Released/updated on: 1999-11-19
Geographic coverage: Canada, Ontario, Global
Time period: 1985-01-01--1988-01-01
This data collection, which was designed to assess experiences with the Ontario, Canada, civil justice system, is a replication and extension of a survey conducted by the Civil Litigation Research Project at the University of Wisconsin. Interviews were conducted with the heads of households. Questions were asked about the nature of the problem, e.g., auto accident, work injury, discrimination, problems with landlord, violations of privacy, or victimization. Questions were also asked about actions taken in response to the problem, such as whether a lawyer was contacted, reasons for not contacting a lawyer, whether non-lawyer assistance was sought, whether a claim was made, and reasons for not making a claim. Finally, questions were asked about the household's experience with the Ontario justice system if a claim was made, including whether there was a trial or a hearing, how much the lawyer charged, evaluation of the result, satisfaction with the result, evaluation of the cost, perceived delay, agreement reached, and compensation awarded. Major demographic variables include age, occupation, number of persons in household, language, ethnic background, religion, education, and family income.

Harnessing Existing Technologies to Mitigate Driving Distraction Among Law Enforcement Officers, Iowa, Tennessee, Wisconsin, Wyoming, 2019 (ICPSR 38994)
Released/updated on: 2026-06-29
Geographic coverage: Iowa, United States, Wyoming, Tennessee, Wisconsin
Nearly half of the law enforcement officers killed in the line of duty in the United States were due to automobile crashes. Driver distraction has been identified as a common causal factor leading to the crash, with the primary source of distractions being the mobile computer. While there is plenty of literature on officer safety, what is lacking is an understanding of the needs of the officers to interact with the control or communication equipment while driving and how that interaction impacts distraction and, consequently, officer safety. To examine these issues, the research team conducted focus group discussions with law enforcement officers from local, county, and state agencies in four states. The two primary topics of discussion were:
- Officer requirements to operate different pieces of equipment while driving, and
- Different software and systems being used in patrol cars.

Impact of Legislation to Prohibit 'Happy Hours' in Indiana, 1983-1986 (ICPSR 9732)
Released/updated on: 2006-01-18
Geographic coverage: Indiana, United States
Time period: 1983-01-01--1986-06-01
This research program was undertaken in Indiana to evaluate the effectiveness of legislation that prohibited "happy hours," the sale of alcoholic beverages at reduced prices during specified times. The happy hour ban sought to curb abusive drinking that can occur when alcoholic beverages are served at significantly reduced prices for a limited time only. The goal of the data collection was to determine whether any reduction in automobile accidents could be attributed to the ban on happy hours. Researchers used an interrupted time-series design to observe trends over time. Data used in this evaluation were extracted from the Accident Statistical Master Tapes for 1983 through 1986 for the state of Indiana, which include annual compilations of all accidents. Variables measure the number of accidents during the specified times. The first data file has as its unit of analysis weeks, defined as beginning Monday and ending on Friday. The second data file has as its unit of analysis bi-weekly periods.

The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.
This research was an evaluation of the Los Angeles Police Department's (LAPD) Training Evaluation and Management System II (TEAMS II) Early Intervention System conducted by Justice and Security Strategies, Inc. TEAMS II was designed to identify officers at-risk for engaging in future problematic behavior. This system was mandated as part of the Consent Decree (Section II) that was formally entered into on June 15, 2001 between the U.S. Department of Justice and the LAPD. Justice and Security Strategies, Inc. research staff worked with the Information Technology Bureau to obtain and analyze TEAMS II data, conducted informal interviews with officers, sergeants, civilians, command staff, and technologists involved with TEAMS II, and worked with the TEAMS II contractors to examine and provide recommendations.
The data collection includes 3 Stata data files. The concentration analysis dataset (TEAMS-Concentration-Analysis-FINAL-v2.dta) with 143 variables for 15,710 cases, the regression-discontinuity dataset (TEAMS-Regression-Discontinuity-FINAL.dta) with 98 variables for 297,779 cases, and the time series dataset (TEAMS-Time-Series-FINAL.dta) with 43 variables for 192 cases.

Minimum Legal Drinking Age and Crime in the United States, 1980-1987 (ICPSR 9685)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1980-01-01--1987-01-01
This collection focuses on how changes in the legal drinking age affect the number of fatal motor vehicle accidents and crime rates. The principal investigators identified three areas of study. First, they looked at blood alcohol content of drivers involved in fatal accidents in relation to changes in the drinking age. Second, they looked at how arrest rates correlated with changes in the drinking age. Finally, they looked at the relationship between blood alcohol content and arrest rates. In this context, the investigators used the percentage of drivers killed in fatal automobile accidents who had positive blood alcohol content as an indicator of drinking in the population. Arrests were used as a measure of crime, and arrest rates per capita were used to create comparability across states and over time. Arrests for certain crimes as a proportion of all arrests were used for other analyses to compensate for trends that affect the probability of arrests in general. This collection contains three parts. Variables in the Federal Bureau of Investigation Crime Data file (Part 1) include the state and year to which the data apply, the type of crime, and the sex and age category of those arrested for crimes. A single arrest is the unit of analysis for this file. Information in the Population Data file (Part 2) includes population counts for the number of individuals within each of seven age categories, as well as the number in the total population. There is also a figure for the number of individuals covered by the reporting police agencies from which data were gathered. The individual is the unit of analysis. The Fatal Accident Data file (Part 3) includes six variables: the FIPS code for the state, year of accident, and the sex, age group, and blood alcohol content of the individual killed. The final variable in each record is a count of the number of drivers killed in fatal motor vehicle accidents for that state and year who fit into the given sex, age, and blood alcohol content grouping. A driver killed in a fatal accident is the unit of analysis.

Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 2001-01-01--2002-01-01
The 2001 National Household Travel Survey is a combination of the Federal Highway Administration's Nationwide Personal Transportation Survey (NPTS) and the Bureau of Transportation Statistics American Travel Survey (ATS), which were conducted separately in previous years. The National Household Travel Survey serves as the nation's inventory of daily personal travel. It collects data on daily trips including purpose of the trip, means of transportation used, travel time, vehicle occupancy, driver characteristics, and vehicle attributes. These data are collected for all personal trips, all modes and purposes, all trip lengths, and all areas of the country, urban and rural. The 2001 National Household Travel Survey collected additional data on trips to a destination 50 miles or more from home (long-distance travel) that started from home and ended at home during a four-week travel period. This was a change from previous years, where the travel range was 75 miles or more. Part 1, the Household File, contains data unique to a household, such as the number of household vehicles, household income, the relationship between household members, demographic information for household members, and educational level of the household respondent. Part 2, the Person File, contains demographic information, driver status, information on travel to work, miles driven, customer satisfaction, and Internet use. Part 3, the Vehicle File, contains data relating to each of the household's vehicles, including annualized vehicle miles. Part 4, the Travel Day Trip File, contains data about each trip the person made on the household's randomly assigned travel day. Parts 5 and 6 are weight files for the Household File (Part 1) and the Person File (Part 2), respectively.

Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 1990-03-01--1991-02-01
This survey provides information on the nature and characteristics of personal travel in the United States. Data are provided on personal trips for all purposes and using all modes of transportation. Both household-level and personal-level data were collected. For each contacted household, information was collected on household vehicles, number of drivers in household, number of accidents during the past five years, availability of public transportation, household location, size and composition of household, and household income. In addition, each household was assigned a specific 24-hour "travel day" and a 14-day "travel period" for which detailed data on all travel were collected. Person-level interviews were attempted with each member of the household over 5 years of age. Persons over 13 years of age were asked to report all trips they had taken on the designated travel day, as well as trips of 75 miles or longer taken during the 14-day travel period ending on the travel day. A knowledgeable household resident, aged 14 or older, was asked to report all trips taken by household members between the ages of 5 and 13 years. The person-level interview also collected information on occupation and work-related travel, driver information, and accidents. The data are provided in six files. Part 1, the Household File, contains demographic information on the household as well as data on drivers and vehicles in the household. Part 2, the Person File, includes demographic data on individuals in the household, information on modes of transportation to work and costs for parking, and details on traffic accidents in the past five years. Part 3, the Vehicle File, provides information on vehicles owned or used by household members, including make, model, year, and mileage.

North Carolina Highway Traffic Study, 2000-2001 (ICPSR 4078)
Released/updated on: 2006-03-30
Geographic coverage: North Carolina, United States
Time period: 2000-01-01--2001-01-01
This study investigated whether the North Carolina State Highway Patrol (NCSHP) practiced racial profiling. The NCSHP provided data on all vehicular stops (Parts 1 and 2), written warnings (Part 3), and citations (Part 4) its officers issued in 2000. This included data on what the stops or tickets were for, the race, sex, and age of the driver, and the make, model, and year of the car being driven. Data on accidents in 2000 (Part 5), also obtained from the NCSHP, were used to examine whether there were racial disparities in unsafe driving practices. These data included information about what caused the accident and the race, sex, and age of the driver. The NCSHP also supplied data on all officers who worked for the NCSHP in 2000 (Part 6), including their race, age, and rank. The data in Part 6 can be linked to the data in Parts 3 and 4. In addition, two surveys of North Carolina drivers were conducted to gather information on reported typical driving behaviors that may influence the probability of being stopped, and to gather information about stops conducted by law enforcement agencies across the state. One was conducted using a sample of North Carolina drivers who had recently renewed their licenses (Part 7), and the other used a sample of North Carolina drivers who were ticketed for speeding between June 1, 1999, and June 1, 2000 (Part 8).
