E-examination TN-Twin Tracker 路面性状計測システム
NEXCO East Japan Engineering Co., Ltd.Product Summary
Road surface condition measurement system
Joint development: Toyo Corporation
車両のルーフ上に取り付け可能。 時速 80km で走行しながら 2 車線幅の路面プロファイルを簡便に測定可能。
Features/Specifications
- Obtain road surface height data for two lanes (7.5m width: sensor installed 2m above ground)
Even if another vehicle enters the laser's range, road surface data can be obtained from areas other than that location. -
エンジン連動Auto Start/Stop機能
車のエンジンのon/offに連動してシステムを起動・停止できます。また、車速（ 時速20km以上など、任意に設定可能）に連動して測定の開始・停止が行われます。 -
路面状況の可視化
路面性状を色分け表示することで、ポットホールや段差等をビジュアル的に把握することが可能。 - Output of CSV files for IRI (International Roughness Index) and rutting depth calculation software
Point cloud data can be converted into a CSV file that is easy to handle and output to software for calculating road surface characteristics such as IRI and rutting. At that time, the position of the reference white line is determined by detecting it using reflection intensity mapping.
