Mohawk Valley Regional ITS Architecture

Interfaces:

Vehicle Environmental Probe Support

• The vehicle shall collect and process environmental sensor data, including air temperature and rain sensors.
• The vehicle shall monitor the status of vehicle convenience and safety systems (wiper status, headlight status, traction control system status) that can be used to measure environmental conditions and record snapshots of significant events in these systems.
• The vehicle shall transmit environmental probe data to the center along with location and timestamp information.
• The vehicle shall transmit environmental probe data to field equipment located along the roadway using short range communications.

MCV Environmental Monitoring

• The maintenance and construction vehicle shall collect environmental data from on-board sensors, including air temperature, wind speed, surface temperature, traction conditions, etc.
• The maintenance and construction vehicle shall transmit environmental sensor data to the center. The sensor data includes location and timestamp information.
• The maintenance and construction vehicle shall provide environmental sensor equipment operational status to the center.
• The maintenance and construction vehicle shall provide environmental sensor equipment fault indication to the center for repair.
• The maintenance and construction vehicle shall collect environmental data from sensors located at the roadway but are monitored on-board a maintenance and construction vehicle.
• The maintenance and construction vehicle shall be capable of accepting sensor control data from the center.
• The maintenance and construction vehicle shall provide control signals to environmental sensors located at the roadway.
• The maintenance and construction vehicle shall transmit environmental sensor data to roadside equipment. The sensor data includes location and timestamp information.

MCV Roadway Maintenance and Construction

• The maintenance and construction vehicle shall track the location and status of safety systems on-board the vehicle.
• The maintenance and construction vehicle shall respond to control information from the center to allow remote operation of the on-board vehicle systems. These systems include routine maintenance equipment for cutting, repairs, hazard removal, etc.
• The maintenance and construction vehicle shall monitor materials information including remaining quantity and current application rate of materials on the vehicle.
• The maintenance and construction vehicle shall respond to dispatch information from the center, presented to the vehicle operator for acknowledgement and returning status.
• The maintenance and construction vehicle shall send operational data to the center including the operational state of the maintenance equipment (e.g., blade up/down, spreader pattern), types and quantities of materials used for construction and maintenance activities, and a record of the actual work performed.

MCV Vehicle Location Tracking

• The maintenance and construction vehicle shall track its current location.
• The maintenance and construction vehicle shall send the time stamped vehicle location to the controlling center.

MCV Vehicle Safety Monitoring

• The maintenance and construction vehicle shall detect that a vehicle has intruded upon the boundary of a work zone. The boundary of the work zone represents an area around the maintenance and construction vehicle, which may be stationary or moving.
• The maintenance and construction vehicle shall receive work zone warnings from the field equipment at the roadside, other maintenance and construction vehicles.
• The maintenance and construction vehicle shall present work zone warnings to the field personnel using direct warning signals or in-vehicle signage functions.
• The maintenance and construction vehicle shall monitor the crew movements to identify when a crew member is crossing the boundary between a work zone and vehicle traffic and issue an alert to the crew member.
• The maintenance and construction vehicle shall provide status of the work zone warning systems to the center.

MCV Vehicle System Monitoring and Diagnostics

• The maintenance and construction vehicle shall collect vehicle diagnostics and operating status data from the maintenance vehicle platform including engine temperature, mileage, tire wear, brake wear, belt wear, and other operational status measures as well as the status of maintenance and construction-specific systems on the vehicle.
• The maintenance and construction vehicle shall use the diagnostic and status information to support scheduling vehicle maintenance, monitoring safety status, and informing the vehicle operator of the conditions.
• The maintenance and construction vehicle shall send the vehicle diagnostic and safety information to an equipment repair facility.
• The maintenance and construction vehicle shall send the vehicle diagnostic and safety information to the controlling maintenance center.

MCV Winter Maintenance

• The maintenance and construction vehicle shall track the location and status of safety systems on-board the vehicle.
• The maintenance and construction vehicle shall respond to control information from the center to allow remote operation of the on-board vehicle systems. These systems include winter maintenance equipment for plowing, treating, and anti-icing.
• The maintenance and construction vehicle shall monitor materials information including remaining quantity and current application rate of materials on the vehicle.
• The maintenance and construction vehicle shall respond to dispatch information from the center, presented to the vehicle operator for acknowledgement and returning status.
• The maintenance and construction vehicle shall send operational data to the center including the operational state of the maintenance equipment (e.g., blade up/down, spreader pattern), types and quantities of materials used for construction and maintenance activities, and a record of the actual work performed.
• The maintenance and construction vehicle shall exchange operational and environmental data with other maintenance and construction vehicles. Operational data includes operational state of the maintenance equipment (e.g., blade up/down, spreader pattern, equipment configuration) and a record of the actual work performed while the environmental data includes environmental sensor data collected on-board a maintenance and construction vehicle, either raw or processed data.

MCV Work Zone Support

• The maintenance and construction vehicle shall monitor, operate, and control work zone devices located at or alongside the roadway. The devices operated on board the vehicle include driver information devices (e.g. dynamic message signs) and work zone intrusion detection and alert devices.
• The maintenance and construction vehicle shall provide an interface for field personnel to input status of their work zone activities.
• The maintenance and construction vehicle shall collect inputs from field personnel and from work zone devices on-board the maintenance and construction vehicle and send them to the controlling center.
