The objective of this study is to evaluate the feasibility of intrusion barriers that will: (1) prevent errant railroad or highway vehicles from intruding into the operational space of an HSGGT guideway from an adjacent or overhead facility; (2) prevent a derailed HSGGT vehicle from intruding into the operational space of adjacent railroad or highway; and (3) prevent a derailed HSGGT vehicle from falling from an elevated track or guideway. This study addresses Maglev, High Speed Rail, Conventional Railroad and Highway vehicles. Alternatives for intrusion barriers along HSGGT guideways are explored, and the feasibility and effectiveness of the various types of intrusion barriers are evaluated. An analysis method is presented and prototype designs shown which can provide a basis for future HSGGT intrusion barrier design nationwide. Eight alternative steel and concrete structural barrier designs are detailed. Barrier construction costs are estimated along with an assessment of the collision damage and repair cost likely to be incurred by vehicles and barriers.
