NDDOT District Offices - Maintenance and Construction Management Functionality
Subsystem Description
The Maintenance and Construction Management Subsystem monitors and manages roadway infrastructure construction and maintenance activities. Representing both public agencies and private contractors that provide these functions, this subsystem manages fleets of maintenance, construction, or special service vehicles (e.g., snow and ice control equipment). The subsystem receives a wide range of status information from these vehicles and performs vehicle dispatch, routing, and resource management for the vehicle fleets and associated equipment. The subsystem participates in incident response by deploying maintenance and construction resources to an incident scene, in coordination with other center subsystems. The subsystem manages equipment at the roadside, including environmental sensors and automated systems that monitor and mitigate adverse road and surface weather conditions. The subsystem manages the repair and maintenance of both non-ITS and ITS equipment including the traffic controllers, detectors, dynamic message signs, signals, and other equipment associated with the roadway infrastructure. Additional interfaces to weather information providers (the weather service and surface transportation weather service providers) provide current and forecast weather information that can be fused with other data sources and used to support advanced decision support systems that increase the efficiency and effectiveness of maintenance and construction operations.
The subsystem remotely monitors and manages ITS capabilities in work zones, gathering, storing, and disseminating work zone information to other systems. It manages traffic in the vicinity of the work zone and advises drivers of work zone status (either directly at the roadside or through an interface with the Information Service Provider or Traffic Management subsystems.) It schedules and manages the location and usage of maintenance assets (such as portable dynamic message signs).
Construction and maintenance activities are tracked and coordinated with other systems, improving the quality and accuracy of information available regarding closures and other roadway construction and maintenance activities.
Functional Area: MCM Automated Treatment System Control
Remotely controls automated roadway treatment systems (to disperse anti-icing chemicals, etc.) directly, or via control of the environmental sensors that activate the treatment systems automatically in the field.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall remotely control automated roadway treatment systems. Treatments can be in the form of fog dispersion, anti-icing chemicals, etc. | Existing |
| 2 | The center shall remotely control the environmental sensors that upon detecting changes in environmental or atmospheric conditions, automatically activate roadway treatment systems. | Existing |
| 3 | The center shall collect automated roadway treatment system and associated environmental sensor operational status. | Existing |
| 4 | The center shall collect automated roadway treatment system and associated environmental sensor fault data and request repair. | Existing |
| 5 | The center shall accept requests for automated roadway treatment system activation from center personnel. | Existing |
Functional Area: MCM Vehicle Tracking
Remotely tracks the location of maintenance and construction vehicles and other equipment; presented to the center personnel.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall monitor the locations of all maintenance and construction vehicles and other equipment under its jurisdiction. | Existing |
| 2 | The center shall present location data to center personnel for the fleet of maintenance and construction vehicles and other equipment. | Existing |
Functional Area: MCM Winter Maintenance Management
Manages winter road maintenance, tracking and controlling snow plow operations, roadway treatment (e.g., salt spraying and other material applications) based on weather information.
| ID | Requirement | Status |
|---|---|---|
| 1 | The center shall respond to requests from emergency management and traffic management centers for hazard removal, field equipment repair, and other winter roadway maintenance. | Existing |
| 7 | The center shall dispatch and route winter maintenance vehicle drivers and support them with route- specific environmental, incident, advisory, threat, alert, and traffic congestion information. | Existing |
| 8 | The center shall determine the need for roadway treatment based on current and forecasted weather information, current usage of treatments and materials, available resources, requests for action from other agencies, and recommendations from the Maintenance Decision Support system, specifically under winter conditions. This supports winter maintenance such as plowing, treating, anti-icing, etc. | Existing |
| 9 | The center shall provide dispatch instructions for vehicle operators based on input parameters from center personnel, specifically for winter conditions. This could include a treatment route, treatment application rates, start and end times, and other treatment instructions. | Existing |
