　東日本高速道路株式会社（以下、NEXCO東日本）と株式会社NTTドコモ（以下、ドコモ）は、ドコモが開発した「AI渋滞予知」^※1の技術を応用し、NEXCO東日本が提供する新サービス「AIルートジャッジ～アクアvs京葉・館山～」（以下、AIルートジャッジ）の実証実験を2025年11月19日（水）から開始します。本実証実験では、木更津JCTから特定のエリア（京葉JCT、箱崎JCT、板橋JCT）までの当日午後の予測所要時間について、CA東京湾アクアライン（以下、アクアライン）を経由するアクアラインルートとE14館山自動車道（以下、館山道）・E14京葉道路を経由する京葉・館山ルートの所要時間を予測し、その比較結果を配信いたします。
　木更津JCTから埼玉方面や東京方面へ向かう際のルート選択にご活用いただけます。

Background to the start of the demonstration experiment

There are two main routes for driving from the Boso Peninsula towards central Tokyo: the Aqua-Line route and the Keiyo-Tateyama route. The "AI Traffic Jam Prediction" currently offered for the CA Aqua-Line, E14 Keiyo Road, and E14 Tateyama Expressway has been well-received by many customers on each route, but there were many requests to know which of the multiple routes would get you there faster, which led to the start of a demonstration experiment. Going forward, we plan to proceed with consideration for full-scale implementation, based on the effectiveness verification of the demonstration experiment and customer feedback.
This service aims to alleviate congestion by dispersing traffic by avoiding traffic jams when heading from the Boso Peninsula towards central Tokyo.

Sections for which estimated travel times are provided

To allow customers heading from Boso towards central Tokyo via roads within the jurisdiction of the Shuto Expressway to choose the best route, the following three routes have been selected as destinations frequently used by many customers from the Aqua-Line Route and the Keiyo/Tateyama Route.

①木更津JCT～外環道　京葉JCTまで（E6常磐道方面）
②木更津JCT～首都高速道路　箱崎JCTまで（都心方面）
③木更津JCT～首都高速道路　板橋JCTまで（E17関越道方面）

How the AI Route Judge works

Docomo's "AI Congestion Prediction" technology, which has previously enabled "AI Congestion Prediction" on the CA Aqua Line and E14 Keiyo Road, has been combined with NEXCO EAST 's traffic engineering knowledge and know-how to produce prediction results. This will be combined with "Tracking Time Sum* ²" data for each time period on each route, based on traffic statistics data from Metropolitan Expressway Co., Ltd., to predict the required travel time for each route and distribute the comparison results.

　NEXCO東日本とドコモは今後も、「AI渋滞予知」のさらなる活用を検討し、交通課題の解決に取り組んでまいります。

2. The sum of tracking times is the total travel time for a vehicle departing from a specific point at a specific time, based on the travel time for each time and each section, taking into account the impact of the movement.
