      <title>HEALTH HAZARD EVALUATION/TOXICITY DETERMINATION REPORT 75-117-372, KOPPERS COMPANY, INCORPORATED, NORTH LITTLE ROCK, ARKANSAS</title>
      <link>https://trid.trb.org/View/57594</link>
      <description><![CDATA[Acting on a request received from an authorized representative of employees regarding their concern over the exposure of workers to creosote and pentachlorophenol, a health hazard evaluation was conducted by NIOSH at the wood treating operation of Koppers Company. The results of air sampling revealed that the workers were exposed to potentially toxic polynuclear aromatic hydrocarbons, while exposures to airborne concentrations of pentachlorophenol were not toxic at the levels encountered. Interviews of 9 of the 11 affected workers disclosed an episode of eye irritation and 4 cases of skin discoloration. Examination of the workers skin revealed 2 cases of mild oil folliculitis and 3 workers with pitch warts, both conditions probably due to creosote exposures. About 45% of the workers interviewed and examined had either elevated or borderline elevated blood pressure levels, although definite conclusions could not be drawn regarding the relationship of the pressor phenomena to occupational exposures. Recommendations are made for improving the existing working conditions and for the application of an occupational medical program.]]></description>

      <title>DATA ANALYSIS FOR DRIVER PERFORMANCE STUDIES. VOLUME I. PDP-8 DATA ACQUISITION SYSTEM FOR DRIVER SIMULATION LABORATORIES</title>
      <link>https://trid.trb.org/View/41353</link>
      <description><![CDATA[A data collection and handling system developed for driving simulation laboratories is described. The system is based on a PDP-8 computer with A/D conversion capabilities and a magnetic tape drive. The systems output is an IBM 360 compatible 9-track magnetic tape. Software developed for sampling and recording driver response data is documented.]]></description>

      <title>DATA ANALYSIS FOR DRIVER PERFORMANCE STUDIES. VOLUME II. A COMPUTER PROGRAM FOR ANALYSIS OF EYE MOVEMENT PATTERNS</title>
      <link>https://trid.trb.org/View/44649</link>
      <description><![CDATA[A digital computer program is described which analyzes visual search data from subjects watching a traffic film while performing a simulated driving task. Classification of eye states into saccades, fixations, pursuits, and blinks, statistical summaries of eye movement patterns, analysis of 'looks' at pre-selected events in the film, and analysis of a discrete response task performed by the subject are included in the capabilities of the program. Sources of error and program accuracy are discussed. The program is written in FORTRAN IV and is presently implemented on the IBM 360 at the UCLA Campus Computing Network. Volume I of this report is entitled PDP-8 Data Acquisition System for Driver Performance Studies.]]></description>
