    GSE RVSS technology can be deployed as either surface mounted or embedded devices, and the provide these benefits;

    1. Slow down vehicles moving too fast.

    2. Provide compressed air for barriers or other uses.

    3. Automatically reset after being triggered.

    4. Present smooth or enhanced traction roadways for traffic.

    5. Minimize the need for police patrols and ticketing.

    6. Can be linked to sensors to provide conditional triggering.

    7. Will stem citizen's protesting about discriminatory  speed cameras.

    8. Eliminate both citizen and emergency vehicle driver complaints and resistance from speed bumps...which are rapidly increasing.

    9. Avoid both potential lawsuits and negative impacts on customer traffic caused by speed bumps on commercial parking lots.

    Anecdote: Drivers of older cars, and the average age of a car in the US is almost 11 years, parking lot speed bumps are a real dis-incentive to patronize a particular mall.  The impact of the often numerous speed bumps on aging suspensions far exceeds the speed control benefits.  Many modern parking lots are refusing to use speed bumps, but expose themselves to accident and potential lawsuits.

    GSE speed sponges are a new and exciting form of speed control that can make the roads safer without burdening law abiding drivers or pedestrians.   

    GSE speed sponge technology unlike police or speed cameras are on the job 24/7, and treat all drivers fairly.   Municipal budgets for policing roadways are becoming increasingly scarce.  Growing budget pressure when combined with citizen pressure about both non-random coverage (profiling) and in-effectiveness (ride any freeway in the world and notice how few people obey posted or safe speed limits), despite the persistence of traffic police.

    As a result of these budgetary, political, and public safety concerns many communities are turning to speed cameras.  Yet, speed cameras have their own problems. 

    First their is a well developed industry that allows drivers to effectively mask their tags from these cameras, using highly reflective paint and other methods. 

    Second, in a society with dramatic income diversity, the speed cameras, which tax but do not censure drivers, are increasingly recognized as an unfair burden on poor and middle income drivers.   

    Anyone may make a mistake or just be in a great hurry, perhaps due to some emergency, few drivers have never exceed the posted speed limits.  However, high income drivers view, even substantial, fines as the cost of doing business [with no points against their license], this is the underlying rational behind the rise of paid express lanes.  While a person on a tight budget with a sick child, often throwing up in the back seat, dares not exceed the speed limit, since a large fine may mean that she has to give up a few family meals next month.

    GSE speed sponge technology solves all of these problems.  Our devices provide equal outcomes to all drivers, despite economic, racial, or political status.   Widely implemented GSE speed sponge technology can reduce the costs of policing, camera maintenance and operations, and actually ensure that all drivers behave safetly.

     

    GSE RVSS are based upon PEC [Pressure to Energy Conversion] a force redirection or vector modification technology. The technology conserves intermittent pressure and momentum energy as heat and gas compression.  The energy conserved  as heated compressed gas is then channeled perpendicular to momentum as exhaust or storage. GSE speed sponge technology can be a compliance component that conforms with CIP-006-1 Physical security of critical cyber assets.

    RVSS technology represents a dramatic new approach to handling excessive vehicle speed, or loss of control.

    RVSS surface mounted Speed Spongestm have the external appearance of large speed bumps.  However, unlike a speed bump, which reflects energy back into the vehicle, surface mounted speed sponges are soft and completely compressible, while an embedded speed sponge is as rigid as the regular roadway. 

    Our embedded models are transparent to all classes of traffic, including cars, trucks, pedestrians and cyclists.  The embedded RVSS units can only be triggered by a heavy vehicle moving at excessive speed. 

    RVSS systems absorb targeted impacts and convert them into gas compression and heat.  RVSS units can be deployed in harsh environmental conditions, including extreme cold, or un-paved roadways

    RVSS technology has many advantages over traditional physical attenuation methods, such guard rails, crushable gravel, nets, or entanglements.

    All RVSS:

    1. Do not impede normal vehicle traffic

    2. Are automatically regenerative

    3.  Can withstand harsh environmental conditions.

    4.  Can be used to pump water or compress air for secondary usage.

    5.  Can be employed without secondary energy generation.

    6.  Can be either engineered, or set in the field, to trigger at specific traffic speeds.

    Embedded RVSS:(only)

    7. Transparent to  all classes of traffic, including cyclists

    8.  Are safe for snow plows with "steel plate" notifications.

    RVSS are naturally regenerative, and can be retrofitted to existing structures. RVSS can easily be relocated as conditions require.

    Naturally regenerative RVSS can remove energy from a targeted process, and within seconds return to 100% capacity.  The regenerative nature of the RVSS makes it ideal for a much wider variety of recurring or non-emergency physical attenuation applications.

    R-series vehicle safety systems [RVSS] are available in both horizontal and vertical orientations.

    Horizontal RVSS: applications

    Horizontal RVSS are alternatives or adjuncts to runaway truck ramps, crushable resistance systems, and entanglement stoppage systems.  The units are either retrofitted or constructed into targeted vehicle surfaces, such as roadways, runways, or ramps. 

     

    GSE RVSS are engineered to impede vehicle momentum in safe low impact steps.  A 40 ton vehicle traveling at 80 mph, would be slowed to 70 mph by the initial RVSS, 55 mph by the second, 40 mph by the third.  This stepped velocity reduction allows the operator to regain control, due to the reduced speed and increased traction. Each stepped reduction. while sudden, is not a threat to the integrity of the vehicle, is operator, or its load.  The effect for the operator of the targeted vehicle is very similar in feel and action, to driving in deep sand.

    The automatic regeneration of the RVSS requires no power not contained in the initial impact.  Each RVSS can provide years of service with no maintenance, and a light inspection regime.

    Traffic calming:

    Horizontal RVSS are designed for permanent placement on roadways; vehicle ramps, such as cloverleaf's and emergency stoppage ramps. RVSS units when employed on sharp or irregular curves, guarantee that drivers maintain optimal operating speeds. 

      This video from a toll plaza in China, perfectly illustrates where our RVSS technology can save lives and property.

    RVSS would have safely slowed this truck significantly before it reached the buildings.

    Repairs, and delays, associated with this crash are estimated to have cost the regional economy approximately 25 million USD.

    Emergency stoppage:

    When employed on emergency ramps, RVSS units can effectively reduce both grade and length required for a given amount of slowdown potential. When  RVSS units are applied to existing ramps, the ramps' engineered limits are effectively upgraded.  RVSS can transform wide shoulders into stoppage ramps, minimizing overall construction costs.

    Security perimeters:

    RVSSH can also be employed as a key component of security perimeters, to slow approaching vehicles.  When employed for security purposes a series of RVSSH units can effectively prevent vehicles from gaining sufficient momentum to compromise security barricades.

    Vertical RVSS

    Vertical RVSS models are designed for wall mounting.  Vertical RVSS can mitigate damage to vehicles and passengers at significantly higher impacts than conventional methods.  RVSS automatically regenerate crash resistance, within seconds of impact, mitigating maintenance costs, and maximizing the availability of protection. GSE vertical RVSS comply with containment level N2 in accordance with EN 1317-2 .

    Vertically mounted RVSS can replace or adjunct existing crash barriers, such as guardrails, retaining walls, and structural voids.  The units are either bolted to existing structures, or integrated during new construction.   RVSS-V are naturally regenerative, providing the highest level of effectiveness when compared to alternative methods.   RVSS-V are generally composed of recycled tires, and can be engineered to a wide variety of cosmetic requirements, including advertising backboards.


    GSE RVSS convert velocity (impacts or inertia) into air or gas compression and heat.  RVSS are maintenance free, and self regenerating. Each unit is engineered to absorbs a fixed amount of energy from impacts safetly reducing vehicle inertia with minimum passenger jarring or vehicle damage.  Horizontal RVSS also increase control traction.

    The energy absorbed by the RVSS is converted into to heat and gas compression.  The compressed gas can be discarded, stored for future usage, or employed immediately in a wide variety of applications, such as barrier activation.  Another byproduct of the RVSS is heat, which can also be employed in a variety of applications.

    .

    RVSS units are bolted to the roadway or walls and are designed for years of maintenance free operation.  Standard RVSS units are built of 90% recycled materials.

    GSE RVSS can maintain high PSI in a compressed air storage tank.  RVSS can  allow the user to directly manage traffic flows, including both average traffic speed, and flow rates.

    The R-series include modular designs which allow systems to be linked to cover roadways of any width.   The higher series models are also designed to work with a wide variety of both road and weather conditions.

    Applications:

    Horizontal RVSS:

    •  Energy and inertia removal from out of control vehicles

    • Security perimeter enhancements

    •  Reduction of vehicle speed and inertia at sharp turns

    •  Traffic calming during emergency repairs or  accident mitigation

    Vertical RVSS:

    - Self-regenerating crash barriers
    - Earthquake buffering for tight clearances
    - Structural damage mitigation
