• Abstract:
  The Small Car Exposure Data Project represents the first phase of an effort to build a data
  
  base of exposure variables for crash-avoidance studies. Among these are: (1) vehicle make,
  
  model, year, body style, wheel base, weight, and horsepower; (2) driver sex and age; (3) vehicle
  
  headway, speed and turning maneuver; (4) permanent site characteristics; and (5) temporary
  
  site characteristics. Phase I data collection took place from March 15 to November 21, 1984
  
  in 12 towns in the western suburbs of Boston. This report is concerned with data collection
  
  methodology and recommendations for its improvement in Phase II.
  
  The most significant methodological change in this study from previous roadside exposure data
  
  collection efforts was the introduction of portable computers. With appropriate software,
  
  these lap computers permitted a single observer to record estimates of vehicle type, driver sex
  
  and age decile, and turning maneuver. The computer also automatically triggered a camera to
  
  photograph the license plate and recorded speed from a radar gun.
  
  In the data editing process, license plates from the film were appended to each record. From
  
  these plate numbers, the Registry of Motor Vehicles supplied the corresponding vehicle
  
  identification numbers. These were run through the VINDICATOR program to generate a file
  
  of output records with all of the vehicle characteristics above.
  
  Traffic counts and Police Accident Report data were also collected for the same area and
  
  time period as the exposure data. All of these data are being analyzed and intepreted in a
  
  report prepared by Mid-America Research Institute.
