"NHTSA Crash Test Deformation and Impact Parameters Dataset (1972\u20132025) for Energy-Equivalent Speed and Severity Modeling"

"This dataset consolidates structured vehicle crash test measurements obtained programmatically via the NHTSA Vehicle Crash Test Database API b29b29b29, covering standardized impact tests conducted between 1972 and 2025 under controlled laboratory conditions. The collection contains vehicle-level and test-level parameters describing frontal impact experiments against rigid barriers, following protocols documented in the NHTSA Test Reference Guide.The dataset includes impact speed (CLSSPD), vehicle mass (VEHTWT), geometric characteristics (wheelbase and structural reference This dataset compiles structured vehicle crash test measurements obtained via the NHTSA Vehicle Crash Test Database API [1], covering standardized frontal impact experiments conducted between 1972 and 2025. The records include impact speed (CLSSPD), vehicle mass (VEHTWT), geometric attributes (e.g., wheelbase), and detailed residual deformation measurements across multiple crush zones (DPD1\u2013DPD6). Spatial geometry descriptors (AX1\u2013AX21 and BX1\u2013BX21) characterize the distribution of structural deformation along the vehicle front. All data originate from instrumented crash tests performed under controlled laboratory conditions following protocols described in the NHTSA Test Reference Guide [2]. The dataset enables research in crashworthiness analysis, accident reconstruction, impact severity modeling, and data-driven estimation of energy absorption, supporting both physics-based and machine learning approaches for studying nonlinear deformation behavior in vehicle collisions. Intended UseThis dataset is intended for research and educational applications in vehicle crashworthiness, accident reconstruction, impact severity analysis, and structural deformation modeling. It is suitable for developing and validating data-driven models, benchmarking physical reconstruction methods, and investigating nonlinear deformation patterns in modern vehicle structures. The data may also support studies in road safety engineering, forensic engineering analysis, and comparative evaluation of crash test protocols.
