1394 Ennis Prismo Traffic Safety Solutions has made a successful first installation of its Stimsonite snow-ploughable road studs in Estonia.
The studs were installed by Road Service, Ennis Prismo’s partner in the country for the 2666 Estonian Road Administration. The Stimsonite 101/944 studs were specified specifically because of the relatively harsh climate in the country, which experiences harsh winters. Snow cover in the country usually lasts from mid-December to late March and snowploughs are widely used to keep roads clear. Standard milled or surface mounted road studs are of no use as the ploughs would either damage them, or strip them away.

The outer body of Stimsonite 101/944 is made from hardened cast iron and is designed to withstand the harshest conditions. It is also designed to be sunk in to the road surface and its curved shape means that the snow plough blades can pass safely over it, without damage to the reflective inserts. These inserts are available in a wide selection of colours and have an abrasion resistant coating to provide enhanced reflectivity. The Stimsonite studs were applied on two projects - the Tallinn-Tartu road (E263) and the Tallinn-Narva road (E20); the latter of these highways being the biggest road construction project in Estonia to date.

    Each year in Germany, up to 80 accidents are caused by drivers on the wrong side of the road, of which many are on- and off-ramps to a main highway. To prevent this, a pilot test has been devised to alert drivers to their wrong-way direction. Cold plastic, one-sided rumble strips are being installed on the road surface within a 100cm-wide by 2cm-deep recessed groove across the lane. The specially shaped cold plastic coating with an uneven, rough bulge gives drivers a strong tactile and acoustic signal, aler
