Active Barrier Systems. Commercially available active vehicle barrier systems are
presented in this section. This listing is only a compilation of reference material and does not imply
endorsement by the government, nor is it a complete listing of vehicle barriers that are
commercially available. Selection of a specific barrier should be based on site conditions and
results of the design, selection, and installation checklist provided in Section 7.5. Results of this
checklist can be used to establish cost, operational, performance and environmental requirements
and select the optimum active and passive barriers from those presented in this section. Users are
advised to consult with manufacturers on current and more detailed information regarding products
and options available. See Appendix A for a list of manufacturers.
NOTE: Information provided below is current as of August 1998, unless otherwise
stated. Cost for selected barriers (those certified by DOS) is provided in Appendix C. A
consolidated list of active barriers, kinetic energy, and penetration data is provided in
Appendix E.
Crisp and Associates Vehicle Surface Barrier.
Description. The vehicle surface barrier (VSB) shown in Figure 10 is a movable, self-
contained, portable (Model VSB 80187-P10) or fixed (Model VSB 80187-F10) roadway barrier. It
can be controlled as a manned checkpoint. Standard equipment is a 50-foot (15.2-meter) cord
attached to a control box. For unmanned control, options include either an electric card reader or
keypad. The self-contained hydraulic system is located in the curb panels and sealed to prevent
fluid leaks. The unit can be placed on any roadway or other flat surface (with passive barriers
installed to prevent bypass). Once the electricity is connected, the system is operational. This
barrier is best used for temporary installations, where high water table is a concern, or where
portability is a requirement. Contact the manufacturer for current cost information. The DOS has
certified this barrier. Performance and cost data are shown in Table 4.
Testing. The VSB was tested by the Naval Facilities Engineering Service Center
(NFESC) at a vehicle barrier test bed in China Lake, California. Upon impact, the cab of a 15,200-
pound (6,909-kg) truck, moving at 50.5 mph (81 kph), was crushed by the impact. The VSB, with
the truck on top, slid 9.2 feet (2.8 m).
