CVO10: Road Weather Information for Freight Carriers

The service package is a special case of the Road Weather Advisories and Warnings for Motorists service package that focuses on Freight Carrier users. It provides the capability to collect road weather data from connected vehicles and using that data to develop short term warnings or advisories that can be provided to individual commercial vehicles or to commercial vehicle dispatchers. The information may come from either vehicles operated by the general public and commercial entities (including passenger cars and trucks) or specialty vehicles and public fleet vehicles (such as snowplows, maintenance trucks, and other agency pool vehicles). The raw data will be processed in a controlling center to generate road segment-based data outputs. The processing will also include a road weather commercial vehicle alerts algorithm to generate short time horizon alerts that will be pushed to user systems and available to commercial vehicle dispatchers. In addition the information collected can be combined with observations and forecasts from other sources to provide medium (next 2-12 hours) or long term (more than 12 hours) advisories through a variety of interfaces including web based and connected vehicle based interfaces.

Includes Physical Objects:

Physical Object Class Description
Basic Commercial Vehicle Vehicle The 'Basic Commercial Vehicle' represents the commercial vehicle that hosts the on-board equipment that provides ITS capabilities. It includes the heavy vehicle databus and all other interface points between on-board systems and the rest of the commercial vehicle. This vehicle is used to transport goods, is operated by a professional driver and typically administered as part of a larger fleet. Commercial Vehicle classification applies to all goods transport vehicles ranging from small panel vans used in local pick-up and delivery services to large, multi-axle tractor-trailer rigs operating on long haul routes.
Commercial Vehicle Driver Vehicle The 'Commercial Vehicle Driver' represents the people that operate vehicles transporting goods, including both long haul trucks and local pick-up and delivery vans. This physical object is complementary to the Driver physical object in that it represents those interactions which are unique to Commercial Vehicle Operations. Information flowing from the Commercial Vehicle Driver includes those system inputs specific to Commercial Vehicle Operations.
Commercial Vehicle OBE Vehicle The Commercial Vehicle On-Board Equipment (OBE) resides in a commercial vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient commercial vehicle operations. It provides two-way communications between the commercial vehicle drivers, their fleet managers, attached freight equipment, and roadside officials. A separate 'Vehicle OBE' physical object supports vehicle safety and driver information capabilities that apply to all vehicles, including commercial vehicles. The Commercial Vehicle OBE supplements these general ITS capabilities with capabilities that are specific to commercial vehicles.
Connected Vehicle Roadside Equipment Field 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.
Fleet and Freight Management Center Center The 'Fleet and Freight Management Center' provides the capability for commercial drivers and fleet-freight managers to receive real-time routing information and access databases containing vehicle and/or freight equipment locations as well as carrier, vehicle, freight equipment and driver information. The 'Fleet and Freight Management Center' also provides the capability for fleet managers to monitor the safety and security of their commercial vehicle drivers and fleet.
Fleet-Freight Manager Center The 'Fleet-Freight Manager' represents the people that are responsible for the dispatching and management of Commercial Vehicle fleets (e.g. traditional Fleet Managers) and Freight Equipment assets. It may be many people in a large tracking organization or a single person (owner driver) in the case of single vehicle fleets. The Fleet-Freight Manager provides instructions and coordination for Commercial Vehicles and Freight Equipment and receives the status of the vehicles and freight equipment in the fleet that they manage.
ITS Roadway Equipment Field 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway. This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.
Surface Transportation Weather Service Center The 'Surface Transportation Weather Service' represents the providers of value-added sector-specific meteorological services. These providers utilize National Weather Service data and predictions, road condition information and local environmental data provided by traffic management or maintenance organizations, and their own models to provide surface transportation related weather observations and forecasts including pavement temperature and conditions.
Traffic Management Center Center The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.
Transportation Information Center Center The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.
Vehicle OBE Vehicle The Vehicle On-Board Equipment (OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The Vehicle OBE includes general capabilities that apply to passenger cars, trucks, and motorcycles. Many of these capabilities (e.g., see the Vehicle Safety service packages) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Route guidance capabilities assist in formulation of an optimal route and step by step guidance along the travel route. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.
Weather Service System Center The 'Weather Service System' provides weather, hydrologic, and climate information and warnings of hazardous weather including thunderstorms, flooding, hurricanes, tornadoes, winter weather, tsunamis, and climate events. It provides atmospheric weather observations and forecasts that are collected and derived by the National Weather Service, private sector providers, and various research organizations. The interface provides formatted weather data products suitable for on-line processing and integration with other ITS data products as well as Doppler radar images, satellite images, severe storm warnings, and other products that are formatted for presentation to various ITS users.

While accuracy of this data is important for decision making purposes, applications should be able to corroborate the data in many instances. Thus MODERATE generally. WYO internally thinks Low or Moderate, depending on the application
Traffic Management Center ITS Roadway Equipment environmental sensors control Moderate Moderate Low
Control flows, even for seemingly innocent devices, should be kept confidential to minimize attack vectors. While an individual installation may not be particularly impacted by a cyberattack of its sensor network, another installation might be severely impacted, and different installations are likely to use similar methods, so compromising one leads to compromising all. DISC: THEA, WYO believe this to be LOW: encrypted, authenticated, proprietary; but should not cause severe damage if seen Should be accurate and not be tampered with; could enable outside control of traffic sensors but should not cause severe harm, but could cause issues with environmental sensor data received and be detrimental to operations; DISC: WYO believes this may be HIGH for some applications Control flow availability is related to the criticality of being able to remotely control the device. For most devices, this is MODERATE. For purely passive devices with no incident relationship, this will be LOW. All devices should have default modes that enable them to operate without backhaul connectivity, so no device warrants a HIGH. From THEAwant updates but delayed information will not be severe; should be able to operate from a previous/default control/config; DISC: WYO believes this to be MODERATE
Transportation Information Center Fleet and Freight Management Center road network environmental situation data Low Moderate Moderate
Aggregated data, but indicates the types of systems and status of those systems on vehicles. Should be LOW, but if identifiers are preserved could be MODERATE. Weather Service providers will have many sources of data, and depend on consistent, quality data inputs, so this data needs to meet similar standards at least in terms of transmission quality. MODERATE or HIGH depending on the context; if critical to some operation then HIGH, if not critical then MODERATE. Weather Service providers will have many sources of data, and depend on consistent, quality data inputs, so this data needs to meet similar standards at least in terms of transmission quality.
Transportation Information Center Fleet and Freight Management Center road weather advisories Low High Moderate
Typically intended for public distribution. Road weather advisory information may be used as part of routing decisions; any corruption of or delay in acquiring this information may lead to suboptimal routing or related decisions, which have a direct impact on safety. HIGH for areas with severe weather consequence. May lower to MODERATE for areas with less severe weather. WYO internally thinks Low or Moderate, depending on the application

Vehicle OBE Connected Vehicle Roadside Equipment vehicle environmental data Low Moderate Low
Little abusive potential for capturing the information in this flow as designed. Could be moderate if this contains PII related information, but considered for now to not include any PII; DISC: WYO believes Vehicle to Center versions of this flow to be MODERATE as center penetrations could more easily garner aggregate user data that might be used for mischief. Some minimal guarantee of data integrity is necessary for all C-ITS flows. DISC THEA believes this to be LOW: Data should be accurate and not tampered with but should be able to cope with some bad data in traffic/environmental condition monitoring; aggregate data; can also receive data from ITS RE; DISC: WYO believes this to be MODERATE data should be timely and readily available, but limited adverse effect; aggregate data; can also receive data from ITS RE; DISC: WYO believes this to be MODERATE

Little abusive potential for capturing the information in this flow as designed. Could be moderate if this contains PII related information, but considered for now to not include any PII; DISC: WYO believes Vehicle to Center versions of this flow to be MODERATE as center penetrations could more easily garner aggregate user data that might be used for mischief. This could be used for safety applications, and in areas of severe weather a corrupted field could have significant consequences; however, any vehicle will use other inputs before triggering automatic safety facilities, so MODERATE should be sufficient. DISC: WYO believes this to be HIGH. This data is required for the system to operate properly. If this data is not available, the system cannot give accurate warning information.
Weather Service System Transportation Information Center weather information Low Moderate Moderate
WYO believes this should be LOW or MODERATE depending on the application. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. There should be other sources of this data. It does need to be reliable however; weather can change quickly, and depending on the destination and its operational strategies, timely response may be important.
