IVHS Countermeasures for Rear-End Collisions. Task 1. Volume 3: 1991 NASS CDSCase Analysis

摘要

The volume of the Task 1 Interim Report for IVHS Countermeasures for Rear-EndCollisions, Contract DTNH22-93-C-07326, deliverable item 5, contains an overview and summary of the analysis of rear-end collision cases from the 1991 National Accident Sampling System Crashworthiness Data System (NASS CDS). The purpose of the analysis was to determine the specific nature of each rear-end collision in order to help identify valid collision countermeasures for each dynamic situation and system type. The different types of dynamic situations are described in detail in Volume I of the report. By analyzing in detail each accident based on the dynamic situation the ocurrance of each type of dynamic situation can be determined. This allows estimation of the occurance of dynamic situations within the entire population of rear-end collisions. Once the population of dynamic situations has been estimated, functional goals can be developed that are qualitative descriptions of the data processing algorithms which will drive the processing function of countermeasure systems. Functional goals will be unique to each dynamic situation and possibly unique to each system type (i.e., headway maintenance, driver warning, automatic control). The clinical analysis performed on the 1991 NASS CDS is also being used to provide inputs to the simulation effort (Task 4).
