MC12-Infrastructure Monitoring (Service Package*)

Description

This service package monitors the condition of pavement, bridges, tunnels, associated hardware, and other transportation-related infrastructure (e.g., culverts) using both fixed and vehicle-based infrastructure monitoring sensors. Fixed sensors monitor vibration, stress, temperature, continuity, and other parameters and mobile sensors and data logging devices collect information on current infrastructure condition. This service package also monitors vehicle probes for vertical acceleration data and other probe data that may be used to determine current pavement condition.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. To support the collection of infrastructure conditions data, Vehicle Subsystem equipment using Field-Vehicle Communications can transmit environmental probe data to equipment located at the Roadway Subsystem (RS) including weather and environmental readings but also conditions of the pavement surface that may indicate areas needing repair. The RS then passes this collected environmental probe data on to the Maintenance and Construction Management Subsystem (MCMS) for analysis.

  2. An additional maintenance activity that can be carried on by the MCMS is control (infrastructure monitoring sensor control) and monitoring (infrastructure monitoring sensor data) of roadway infrastructure sensors which are used to assist in identifying infrastructure repair needs.

  3. The MCMS can send maint and constr vehicle system control commands to the Maintenance and Construction Vehicle Subsystem to manage the control and monitoring of the infrastructure via the vehicle fleet. MCVS, in this scenario, is controlling (infrastructure monitoring sensor control) and monitoring (infrastructure monitoring sensor data) of infrastructure sensors located at the Roadway Subsystem. The infrastructure data is passed along to the MCMS (infrastructure conditions data).

  4. Finally, Asset Management sends recommended strategies and schedules for maintenance of the transportation infrastructure (maintenance and repair needs). The MCMS provides back to Asset Management changes to the status of pavement, bridges, signs and other assets resulting from infrastructure maintenance and repair activities (asset status update). This same flow can also contain results of infrastructure monitoring carried out by the maintenance organization.
