iNFRA Develops HD Map System for M7-M9 Motorway Inspection

iNFRA Presents Pavement Condition Survey Results for M7 and M9 Using HD Map Technology

On 25 May 2026, iNFRA Plus Co., Ltd. conducted a technical presentation summarizing pavement condition survey results and data verification approaches under the road inspection, condition analysis, and High-Definition Mapping (HD Map) development project for Motorway No. 7 and Motorway No. 9.

The session was attended by Mr. Suwich Rodpai, Director of the Intercity Motorway District, together with Mr. Worapong Khwakong, Deputy Director of the Engineering Division, and related government officials at the 3rd Floor Meeting Room of the Intercity Motorway District Office.

The presentation covered key pavement condition indicators, including IRI (International Roughness Index), MPD (Mean Profile Depth), and RUT measurements, which are used to evaluate road surface quality, driving smoothness, and the operational performance of motorway pavement structures.

In addition, iNFRA introduced methodologies for verifying data accuracy and completeness to support efficient transportation infrastructure management, long-term pavement maintenance planning, and data-driven motorway development strategies.

This project reflects iNFRA’s commitment to applying advanced survey technologies and engineering data analytics to enhance roadway safety standards and support sustainable transportation infrastructure management in Thailand.
