JR Central Publishes Height Restriction Information to Prevent Vehicle Collisions at Railway-Road Intersections
To prevent vehicle collisions with railway bridges, JR Central will start providing height restriction information for 1547 locations across its entire area to a digital map jointly operated by JR West and Mapple, effective May 22, 2026.

Central Japan Railway Company (President and Representative Director: Shunsuke Niwa; hereafter JR Central) will provide height restriction information for railway-road intersections along its lines to a digital map jointly created and published by West Japan Railway Company's Kinki Area Headquarters (Executive Officer, General Manager: Naoki Tomimoto; hereafter JR West) and Mapple Inc. (President and Representative Director: Yuki Obinata; hereafter Mapple), as a countermeasure against vehicle collisions with railway bridges. This will further expand the scope for drivers, especially of large vehicles or those carrying cargo, to confirm passable heights in advance.
■ Background
- In fiscal year 2025, 138 vehicle collisions with railway bridges (including bridge protection facilities) occurred at railway-road intersections along JR Central lines. Some cases involved major damage to bridge protection facilities or the dropping of cargo due to collisions, and have also led to train delays for safety checks of railway facilities.
- To suppress such accidents, JR Central has implemented measures such as improving the visibility of bridge protection facilities, installing height restriction signs, and distributing posters to raise awareness about preventing railway bridge collisions.
■ Overview of the Digital Map
- This map was jointly created by JR West and Mapple in 2022 and contains height restriction information for railway-road intersections.
- The information is published on the 'MAPPLE Route Search' screen of 'Mapple Lab,' where Mapple showcases services in new areas and focus fields.
- In the Keihanshin area, where JR West introduced this ahead of others in September 2022, transport disruptions* due to collisions with railway bridges have decreased from 16 cases in fiscal year 2018 to 5 cases in fiscal year 2025, partly due to the effects of PR activities for the digital map.
* Incidents involving passenger train delays of 30 minutes or more.
■ Implementation Details
- Starting Friday, May 22, 2026, height restriction information for bridges (1547 locations) at railway-road intersections in all JR Central areas will be added to the digital map. This is expected to further enrich the information posted on the digital map and lead to a reduction in vehicle collisions with railway bridges.

FAQ
JR東海が今回発表した対策の内容は？
JR東海沿線の鉄道・道路交差部における橋梁の高さ制限情報（1547地点）を、JR西日本と株式会社マップルが運営するデジタルマップへ提供し、公開します。
このデジタルマップは何のためにあるのですか？
主に大型車両や積載物を運搬する車両のドライバーが、通行可能な高さを事前に確認できるようにし、鉄道橋梁への自動車衝突事故を抑制することを目的としています。
導入の背景にある事故の現状は？
2025年度、JR東海沿線では鉄道橋梁への自動車衝突事故が138件発生しており、橋梁防護施設の損傷や積載物の落下、列車遅延の原因となっています。
デジタルマップはどこで確認できますか？
マップルが運営する「マップルラボ」の「ＭＡＰＰＬＥのルート探索」画面上にて公開されています。
この取り組みによる期待効果は？
事前に高さ制限を確認可能にすることで、鉄道橋梁への自動車衝突事故の抑制が期待されます。先行導入のJR西日本京阪神地区では、輸送障害が大幅に減少する実績があります。
