| Functional Object | Description | User Defined |
|---|
| MCM Automated Treatment System Control | 'MCM Automated Treatment System Control' remotely monitors and controls automated road treatment systems that disperse anti–icing chemicals or otherwise treat a road segment. The automated treatment system may be remotely activated by this object or it may include environmental sensors that activate the system automatically based on sensed environmental conditions. This object monitors treatment system operation, sets operating parameters, and directly controls system activation if necessary. | False |
|---|
| MCM Environmental Information Collection | 'MCM Environmental Information Collection' collects current road and weather conditions using data collected from environmental sensors deployed on and about the roadway. In addition to fixed sensor stations at the roadside, this functional object also collects environmental information from sensor systems located on Maintenance and Construction Vehicles. It also collects current and forecast environmental conditions information that is made available by other systems. The functional object aggregates the sensor system data and provides it, along with data attributes to other applications. | False |
|---|
| MCM Environmental Information Processing | 'MCM Environmental Information Processing' processes current and forecast weather data, road condition information, local environmental data, and uses internal models to develop specialized detailed forecasts of local weather and surface conditions. The processed environmental information products are presented to center personnel and disseminated to other centers. | False |
|---|
| MCM Field Asset Tracking | 'MCM Field Asset Tracking' maintains a database of field assets and their locations. It shares this asset tracking data with other maintenance and construction applications that monitor and use the assets. It also identifies assets in travel lanes that may pose a safety hazard and shares this information for use in mitigating the safety risk through local vehicle warnings and maintenance crew notification. | False |
|---|
| MCM Field Equipment Maintenance | 'MCM Field Equipment Maintenance' provides overall management and support for maintenance of field equipment on a roadway system, right–of–way, parking area, transit stop, or other areas where field equipment exists. Services include repair and maintenance of ITS field equipment in these areas (e.g., detectors and other sensors, cameras, dynamic message signs, electronic toll collection equipment, electronic clearance equipment, weigh–in–motion sensors, etc.). | False |
|---|
| MCM Infrastructure Monitoring | 'MCM Infrastructure Monitoring' monitors the condition of pavement, bridges, tunnels, associated hardware, and other transportation–related infrastructure (e.g., culverts). It monitors the infrastructure, collecting data from both fixed and vehicle–based sensors. In addition to specialized infrastructure monitoring sensors, it also monitors the broader population of equipped vehicles for vertical acceleration data and other situation data that may be used to determine current pavement condition. | False |
|---|
| MCM Maintenance Decision Support | 'MCM Maintenance Decision Support' recommends maintenance courses of action based on current and forecast environmental and road conditions and additional application specific information. Decisions are supported through understandable presentation of filtered and fused environmental and road condition information for specific time horizons as well as specific maintenance recommendations that are generated by the system based on this integrated information. The recommended courses of action are supported by information on the anticipated consequences of action or inaction, when available. | False |
|---|
| MCM Reduced Speed Zone Warning | 'MCM Reduced Speed Zone Warning' supports remote control and monitoring of reduced speed zone warning roadside equipment. It provides posted speed limits and associated schedules and information about associated road configuration changes including lane merges and shifts. It monitors field equipment operation and reports current status to the operator. | False |
|---|
| MCM Remote Vehicle Control | 'MCM Remote Vehicle Control' provides the capability for center personnel to control unmanned surface and aerial vehicles that support surface transportation operations and maintenance. The remote control capability includes the capability to control the vehicles location, trajectory, and velocity and additional application–specific controls that control the operations and maintenance capabilities provided by the remote controlled vehicle. Note that center–based control relies on sophisticated automated control capabilities on–board the vehicle with a sufficient operational design domain so the vehicle can operate safely without second–by–second control in most environments and scenarios. | False |
|---|
| MCM Roadway Maintenance | 'MCM Roadway Maintenance' provides overall management and support for routine maintenance on a roadway system or right–of–way. Services managed include landscape maintenance, hazard removal (roadway debris, dead animals), routine maintenance activities (roadway cleaning, grass cutting), and repair and maintenance of non–ITS equipment on the roadway (e.g., signs, gantries, cabinets, guard rails, etc.). Environmental conditions information is also received from various weather sources to aid in scheduling routine maintenance activities. See also MCM Field Equipment Maintenance for maintenance of ITS field equipment. | False |
|---|
| MCM Traffic Information Dissemination | 'MCM Traffic Information Dissemination' uses dynamic message signs to disseminate traffic and road conditions, closure and detour information, incident information, driver advisories, and other maintenance–related data. It monitors and controls driver information system field equipment including dynamic message signs, managing dissemination of driver information through these systems. | False |
|---|
| MCM Vehicle Maintenance Management | 'MCM Vehicle Maintenance Management' monitors vehicle and equipment condition, tracks maintenance history, and schedules routine and corrective maintenance based on vehicle/equipment utilization and availability schedules. | False |
|---|
| MCM Vehicle Tracking | 'MCM Vehicle Tracking' tracks the location of maintenance and construction vehicles and other equipment. Vehicle/equipment location and associated information is presented to the operator. | False |
|---|
| MCM Winter Maintenance Management | 'MCM Winter Maintenance Management' manages winter road maintenance, tracking and controlling snow plow operations, roadway treatment (e.g., salt spraying and other material applications), and other snow and ice control operations. It monitors environmental conditions and weather forecasts and uses the information to schedule winter maintenance activities, determine the appropriate snow and ice control response, and track and manage response operations. | False |
|---|
| MCM Work Activity Coordination | 'MCM Work Activity Coordination' disseminates work activity schedules and current asset restrictions to other agencies. Work schedules are coordinated with operating agencies, factoring in the needs and activities of other agencies and adjacent jurisdictions. Work schedules are also distributed to Transportation Information Centers for dissemination to the traveling public. | False |
|---|
| MCM Work Zone Management | 'MCM Work Zone Management' remotely monitors and supports work zone activities, controlling traffic through dynamic message signs (DMS), Highway Advisory Radio (HAR), gates and barriers, and informing other groups of activity (e.g., traveler information, traffic management, other maintenance and construction centers) for better coordination management. Work zone speeds, and delays, and closures are provided to the motorist prior to the work zones. This application provides control of field equipment in all maintenance areas, including fixed and portable field equipment supporting both stationary and mobile work zones. | False |
|---|
| MCM Work Zone Safety Management | 'MCM Work Zone Safety Management' remotely monitors work zone safety systems that detect vehicle intrusions in work zones and warns crew workers and drivers of imminent encroachment. Crew movements are also monitored so that the crew can be warned of movement beyond the designated safe zone. | False |
