      <title>HUMAN FACTORS COUNTERMEASURES TO IMPROVE HIGHWAY-RAILWAY INTERSECTION SAFETY</title>
      <link>https://trid.trb.org/View/10572</link>
      <description><![CDATA[A field demonstration study in support of the evaluation of alternative railway-highway grade crossing accident countermeasures was conducted. Guidelines were provided for the development of countermeasure concepts. Investigations of the causative factors of accidents showed that maintenance of protective warning devices, driver attention and driver expectancy were precipitating and predisposing factors in accidents. An appraisal of inherent driver safety potential was made which included driver education and licensing, safety programs and law enforcement, attitude and habit components of railway-highway safety and psychophysiological capabilities and limitations. A broad base of data was obtained in a demonstration field study conducted in five states. (Modified author abstract)]]></description>

      <title>BASIC RESEARCH IN CRASHWORTHINESS II. FURTHER REFINEMENT IN ENGINE DEFLECTION CONCEPT</title>
      <link>https://trid.trb.org/View/10227</link>
      <description><![CDATA[An engine deflection, front structural modification to a full size automobile is refined from a concept that was developed within a previous program. The refinement includes use of normal automobile materials in the structure and a significant weight decrease from that utilized on the original concept. Although no operational automobiles were developed in this phase of the overall program, provisions were made for all normal operational requirements. Structural performance of the originally modified vehicles during fixed object collisions was maintained with the refined vehicles. Additional data were obtained for intervehicular tests involving full size automobiles, including both front-to-side and front-to-front impacts between full size automobiles. In addition to results for numerous low speed impacts, data on the performance of the modified front structure during twelve different tests where impact speed ranged from 30 MPH to 60 MPH were developed.]]></description>

      <title>BASIC RESEARCH IN CRASHWORTHINESS II. EXPERIMENTAL VALIDATION STUDY FOR THE LARGE DEFLECTION DYNAMIC ANALYSIS OF PLANE ELASTO-PLASTIC FRAME STRUCTURES</title>
      <link>https://trid.trb.org/View/10228</link>
      <description><![CDATA[A validation study is made for the analytical predictive technique developed for the large-deflection static and dynamic analysis of plane elasto-plastic frame structures. The test apparatus and test results for four mild steel frame/rigid barrier impact (or crush) tests conducted specifically for this purpose at Calspan Corporation are described. The test results are then compared with the corresponding analytical results. It is found that, in the dynamic cases studied, the analytical results which include material rate-sensitivity effects correlate reasonably well with the experimental results, while the analytical results which do not include such effects correlate very poorly with experiment.]]></description>

      <title>PERFORMANCE EVALUATION OF THE GENERAL MOTORS HYBRID II ANTHROPOMORPHIC TEST DUMMY</title>
      <link>https://trid.trb.org/View/14270</link>
      <description><![CDATA[A series of twelve static and dynamic component tests were performed to measure the GM Hybrid II dummy in accordance with the purchase description test procedures and specifications. Twenty type-2 belt restraint tests and twenty air bag restraint tests were performed using an accelerator sled to simulate a 30-mph impact crash. The dynamic performance of the dummies was statistically the same in terms of absolute value and variability of the measured parameters. The GM Hybrid II dummy exhibits statistically the same variability as the Alderson hybrid dummy previously tested under contract DOT HS-053-1-129, but has significantly different absolute values for the dynamic test parameters.]]></description>

      <title>STABILITY AND HANDLING CRITERIA OF ARTICULATED VEHICLES. PART I. TECHNICAL REPORT</title>
      <link>https://trid.trb.org/View/14271</link>
      <description><![CDATA[An analytical and experimental investigation on the stability and handling of articulated vehicles was conducted to develop stability criteria for tractor single-, double-, and triple-semitrailer vehicles during commonly encountered road and speed maneuvers subject to environmental influences. To this end, an experimentally validated digital simulation model, AVDS3, was further developed and validated. It was utilized to generate physical stability limits for articulated vehicles. During the investigation, the direct method of Lyapunov was employed to generate mathematical stability limits of cornering articulated vehicles. In addition, an effort was made to apply the concept of finite time stability to this problem. Portions of this document are not fully legible.]]></description>

      <title>OPTIMUM TWO-LAMP HEADLIGHTING SYSTEMS</title>
      <link>https://trid.trb.org/View/10581</link>
      <description><![CDATA[The development of a three-beam mode, two-headlamp lighting system was studied; beam pattern specifications for optimized low, mid, and high beams were devised and used as targets for lamp construction. Comparative visibility with lamps based on these specifications was not as good as that from similar three-beam mode, four-headlamp systems, and it was concluded it could not be made so.
