ABSTRACT:
A race track is disclosed having a tri-oval banked, racing surface surrounded by a barrier support material delineating a race barrier support surface at a level below the racing surface. A plurality of barrier modules are mounted on the support surface in longitudinally aligned relationship to delineate two crash barrier rings circumscribing the racing surface. Each of the modules includes a base mounted on the barrier support surface with the inner ring in juxtaposed relationship with the racing surface. Each base includes a top surface substantially in elevational alignment with a perimetral portion of the racing surface. Each module includes a vehicle impact energy absorbing means mounted on and connected to its base for cushioning energy absorption upon impact by an out of control race vehicle; and, each module base and a portion of the barrier support material upon which that module is mounted together forming a further vehicle energy absorbing means. A method of conducting vehicle racing contests is also disclosed. The method includes constructing a plurality of race tracks of substantially equal configurations dimensionally, conducting racing events with vehicles each equipped with power trains and tires respectively constructed to a set of specifications such that competing vehicles have substantially equal performance capabilities, determining the relative position of each competing vehicle at the conclusion of each event, assigning values to the vehicles recording to the position determinations, and, utilizing the assigned values to determine an overall winner of a series of events.
