PAS 2161 conformity in RoadAI

In PAS 2161 RCM technology type classification, RoadAI is classified as RCM technology type M.

Type M: Dedicated mobile technologies Individual, mobile, portable data collection devices, typically installed in a vehicle on a temporary or permanent basis specifically for the collection of RCM data. This typically involves small-scale image collection, such as mobile phone or dash-cam technologies supported by a global navigation satellite system (GNSS), running bespoke applications. Collection is managed or controlled by data collector operatives, or operatives trained in the use of the system.

RoadAI’s PAS 2161 data production is based on specific versions of the RoadAI computer vision-based distress detector, automated video quality control, and PAS 2161 category classification models. The process for producing the data is as follows:

  1. The distress detector model produces the road condition raw data.
  2. The PAS 2161 video quality control model is used for qualifying video footage for PAS 2161 use.
    • Video sections not suitable for data production, for example, due to poor weather or lighting conditions, are disqualified in accordance with PAS 2161 requirements.
  3. The RoadAI PAS 2161 road condition classifier model converts distress detections into PAS 2161 road condition categories.
RoadAI produces, displays, and reports PAS 2161 road condition data at the required 10–meter resolution.
