Terminal Obstacle Protection Ermes T4 110 km/h.

Road Safety

Rijkswaterstaat has published the Compendium of Starting Points for Guardrail Constructions as a supplement to the Motorway Design Directive (ROA). The start of the guardrail is no longer buried but provided with a Terminal, also called EndTerminal. Rijkswaterstaat requires that the Terminals be sufficiently strong to function as an anchorage with which the pull-through forces of the connecting guardrail can be absorbed. The Ermes Terminal T4 with connecting guardrail has been tested for these tensile forces and amply meets Rijkswaterstaat's requirement of 250 kN. We can even absorb tensile forces of 400 kN and 600 kN. Compensating measures such as an extra rail or special constructions are not necessary. This makes installing our terminal simple and affordable. Install the terminal and connect the (existing) guardrail to the terminal. The narrow Ermes Terminals are also very suitable for central reservation security thanks to the double-sided operation in 2 directions.

End Terminal

Application parallel or deflected guardrail construction with terminal as starting point

If an obstacle cannot be shielded with a crash cushion, a guardrail construction must be used. The starting point of the guardrail structure shall be located such that vehicles moving off the road do not touch the obstacle. A fixed angle of five degrees is used for this. When sufficient space is available upstream in the cross section, the guardrail construction must be designed in a curved manner. On the basis of the formulas below, the road designer must determine the required length of the barrier provision upstream of the obstacle. An arrangement with deflection after 8 meters (Ll) is preferred here. If an arrangement with deflection is not possible, a parallel arrangement can be realized. The designer should strive for a solution with a minimum construction length, the curved design is therefore preferred. The starting point of the guide rail construction is formed with a terminal. The starting point of the guardrail construction is a terminal that complies with the performance class according to prEN 1317-7 based on the design speed: Vo = 50 km/h: T50, Vo = 70 km/h: T80, Vo = 90 km/h: T100 , Vo = 120 km/h: T110 with ASI value A or B.

Tested according to EN1317

The Terminal Ermes T4 has been tested as a terminal according to ENV1317-4 and prEN1317-7, but also as a crash cushion according to EN1317-3 up to 110 km/h. and is therefore the only terminal in the market with CE marking. This terminal guarantees the best performance for vehicle occupants in the event of an unexpected collision. Thanks to the modular construction, damage can be repaired quickly and easily after a collision, often on site. Parts of this terminal are up to 80% reusable and 100% recyclable. In this way, huge savings can be made on the costs of damage repair.

Ready for the future

The use of electric, larger and heavier vehicles is constantly increasing. In order to optimally protect the start of guardrails and obstacles along roads for these heavier vehicles, we supply and install these durable and maintenance-free Ermes Terminals that have been tested for these heavier vehicles. The Ermes Terminal T4 is the only Terminal that has been tested with a 2000 Kg vehicle. By installing these terminals, Road Safety is ready for the future. The Ermes End-Terminal T4 adds a new standard to the Dutch market. The performance (D1 and Z1) of a crash cushion for the price of a terminal.

Wooden Guide Rail

Wooden crash barriers are increasingly being installed because it is durable and fits better into the streetscape. Wooden guide rail constructions are often composed of wood and steel and are available in different performance classes. Because a steel start construction does not aesthetically match a wooden endterminal, the start is often buried at an angle. This is not a safe solution. Vehicles can be launched or shoot uncontrollably into the roadway. We have now devised a safe solution to properly secure the beginning of the wooden guardrail and not to detract from the aesthetics of the wooden crash barrier. The Ermes Terminals sprayed in color from the connecting wooden guardrail. The Ermes Terminals can be seamlessly connected to the wooden guardrail with tailor-made connections, so that the start of the guardrail is optimally secured.

Easy repair and maintenance

With NFC technology, we can easily map our installed traffic safety systems. An NFC Tag is mounted on every Terminal, Crash Cushion or Guardrail. As soon as you hold a smartphone in front of the NFC Tag, the App will open automatically. Clear instructions are given step by step on how to install the roadside protection. At each step a photo and possibly a comment can be added. When all steps have been completed, the data, including the GPS position, will be centrally stored on our portal. All data about the placement, model, type and year of construction are then available via the Portal. After a collision, this data can be passed on to us, so that the damage can be repaired quickly and the road is safe again. An extensive manual is also available in the NFC Tag. The damage can be easily repaired via a step-by-step plan, with photos of the various parts.
