City of Klamath Falls, OR - Pavement and Asset Management System

Description:

The DTS team conducted a mobile data collection project for the City of Klamath Falls, OR that included data collection for Pavement Condition, Signs and Curb & Gutter. The DTS mobile data collection vehicle was used to collect the City’s road network using mobile video and LiDAR. This data was controlled using GPS, Inertial Navigation, and ground survey.

The mobile video was processed to create a geospatially accurate pictures that are used to extract asset information. First, signs were extracted automatically by using the intensity measurements from the mobile LiDAR scanner. Once the signs were identified, the DTS team assigned a MUTCD code from the existing sign library. Sign condition, dimensions and post types were also extracted from the pictures.

The pavement condition index (PCI) was collected in the field using engineers from Resource International, Inc (Rii). The pavement distress type, severity and extent were measured using the ASTM D6433 modified PCI approach. All segments were rated using this methodology to develop a rating from 0 (Failed) – 100 (Newly Constructed). All of this information was then used to develop a Capital Improvement Plan (CIP) focused on the highest priority roads needing maintenance performed on them.
