 NEXCO東日本新潟支社(新潟市中央区)では、11月28日(火)に新潟県内などの高速道路4カ所のサービスエリア(SA)・パーキングエリア(PA)で今冬期3回目の冬用タイヤ装着率調査を実施し、その結果、冬用タイヤ非装着率は全体で12%でした。
 この調査は冬用タイヤの早期交換を喚起し、冬道の安全運転を啓発することを目的として実施しています。まだ、冬用タイヤを装着されていない場合は、早めの冬用タイヤへの交換とチェーン携行をお願いいします。また、高速道路をご利用の際には安全な運転をお願いします。

1. 1. Outline of winter tire installation rate survey

Survey method

  • Surveyor visually confirms the tire type of the vehicle parked in the SA / PA surveyed
  • Investigate about 50 units at one location
  • Large vehicles are oversized vehicles, large vehicles, medium-sized vehicles, and small vehicles are regular vehicles and light vehicles classified by charge type.

Survey place

E17 Kan-Etsu Expressway Tanigawadake PA,
E8 Hokuriku Expressway Kurosaki PA, Hokuriku Expressway Yoneyama SA,
E18 Joshinetsu Expressway Myoko SA

  • All carried out on the Out-bound

3. Three points for driving safely Expressway in winter

  1. Early winter equipment (installation of winter tires, carrying chains)
    • Winter is almost here. Please change to winter tires as soon as possible.
    • Make sure that the tread depth of your winter tires is no more than 50% worn down when new.
    • During heavy snowfall, chains may be required even on winter tires. Please be sure to carry a chain.
  2. Drive safely and reduce your speed (especially in early winter!)
    • Do not perform operations with the word ``sudden'' such as ``sudden steering,'' ``sudden acceleration,'' or ``sudden braking.''
      Please drive slowly and safely, keeping a sufficient distance between vehicles.
    • In particular, at the beginning of winter, drivers tend to be more prone to accidents as their sense of driving on snowy roads has not yet recovered.
  3. Frequently gathering information before and during your outing
    • The weather on Expressway in winter can change rapidly, and even if it's sunny at your departure point, it may be snowing at your destination or passing point.
      Please check road and weather information frequently before going out or while taking a break in the service area.
    • "Drive Traffic (DraTra)" provides real-time traffic information and information on Expressway road conditions (snowy road live camera).

Four. About stacking during snowfall

  • Stuck is more likely to occur during snowfall.
  • NEXCO EAST official YouTube channel introduces the mechanism by which stacks occur and how to prevent them from occurring. Please take a look at it as a reference for safe driving.

NEXCO EAST, in order to use the winter Expressway safely, securely, comfortably and conveniently, safety awareness activities and traffic safety campaigns at SA / PA / toll offices, and national Expressway / SA information site "DraPla" , "Dr. Mammoshi's Winter Expressway Course" is actively disseminating information on snowy roads.

The NEXCO EAST Group has positioned the period from 2021 to 2025 as "a period to contribute to the achievement of the SDGs and transform toward a new future society", and is carrying out various initiatives.
We believe that the implementation of this winter tire installation rate survey will contribute to SDG Goal 3 as a business activity that will lead to the reduction of casualties due to traffic accidents.
