As part of the City's Pavement Management and Right-of-Way (ROW) Asset Inventory Project, over the next several days, Transmap Corporation will be working within the City inventorying images of Shoreline's road network.

To do this, Transmap's On-Sight HD Mobile Mapping Vehicle (van) will drive around the city collecting digital imagery and GPS information of roadways. Information collected helps complete a citywide pavement condition assessment and collect and incorporate ROW asset data into the City's asset management system.

Transmap uses a high definition mobile mapping system to capture photogrammetric images of the pavement every 300 feet. The mobile mapping system collects data at normal driving speeds so special traffic control devices are not required during data collection.

The Pavement Management and ROW Asset Inventory Project addresses two important issues for City infrastructure maintenance.

  1. First, the project will complete a pavement condition assessment for 165 centerline miles of City roads. The condition assessment includes calculating a pavement condition rating, which will be used to define and guide pavement maintenance priorities in the future. Pavement condition information will be stored in the City asset management system (Cityworks) and a specific pavement management software (MicroPaver) so asset condition can be tracked through time.
  2. Second, the project will complete an inventory of ROW assets (e.g. sidewalks, ADA Ramps, traffic signs and signals, pavement markings, etc.) and deliver the data into the Cityworks and GIS systems. Having a detailed ROW asset inventory will allow staff to track asset condition and develop systematic and prioritized work plans for improvement and maintenance projects.

The Project supports the City’s commitment to appropriately and proactively manage its assets.
