District 13 Operations
The United States Department of Transportation has initiated a Connected Vehicle Pilot Deployment effort. Local transportation agencies, cities, municipalities, and private industry will be invited to submit cooperative pilot proposals for funding and support. These pilot programs will produce operational deployments that will harness the capabilities of connected mobile and wireless technologies to provide mobility, safety, and environmental benefits. The USDOT will seek partnerships among State and local transportation agencies, commercial vehicle operators, private companies, and others to select and deploy appropriate connected vehicle solutions from across all elements of surface transportation (such as transit, freeway, arterial, parking facilities, tollways, or ports) to address local needs and performance goals. The local partners will select from among many beneficial applications to address their most pressing needs. Now I will go through the District 13 Operations sample scenario
District 13 is a three-county district in the northern United States. It is subjected to significant and frequent snowfall, and winter operations focus on anti-icing and snow removal. During the summer season, operations focus on pavement assessment and maintenance. As a consequence, work zones coincide with increased summer travel, causing significant delays.
District 13's stakeholders convene to discuss their key transportation challenges. Frequent snowfall during the winter season increases costs while maintenance budgets continue to shrink. The stakeholders aim to reduce operational cost on both snow plowing operations and pavement maintenance. Summer roadwork and tourism combine to create unpredictable congestions, resulting in delay and safety impacts.
Based on the identified challenges, the local stakeholders discuss performance measures and improvement targets. The stakeholders aim to reduce snow removal time by 10% and lower plowing operations costs by 10%; additionally, they aim at reducing the number of customer calls regarding dangerous pot holes on roads by 25%, and to cut work zone crashes by 80% and delay by 30% during the summer season.
This is the full catalog of USDOT applications designed to address mobility, safety, and environmental concerns. The stakeholders then select applications to achieve these targets. To improve snow removal, the stakeholders select the Enhanced Maintenance Decision Support System (also known as the Enhanced MDSS) road weather application. This application will acquire road-weather data from connected vehicles as well as from other traditional sources of weather data to recommend treatment plans and weather response plans to snow plow operators and to transportation [maintenance?] managers.
To improve pavement maintenance, the stakeholders select the Probe-based Pavement Maintenance application. This application allows vehicles to automatically report potholes or other pavement surface anomalies that affect the quality of the ride.
To improve work zone safety and mobility, the stakeholders select the Work Zone Traveler Information application. This application monitors and aggregates work zone traffic data, allowing transportation officials to make any necessary adjustments and to convey the information to the travelers in near real time.
This slide presents the three applications selected by the stakeholders for deployment in District 13. The next three slides show how these applications are projected to work to improve snow and ice control, pavement maintenance, and work zone management.
This slide illustrates the Enhanced Maintenance Decision Support System. The projected impacts include a 10% reduction in snow removal time, a 10 % reduction in resource utilization (namely labor hours, winter chemicals, and fuel), and a decrease in crashes resulting from improved snow and ice removal operations; all of this while reducing the ecological impacts of winter maintenance operations.
This slide illustrates the Probe-based Pavement Maintenance application that was selected to improve pavement distress situational awareness. The projected impacts include automatic reporting of road maintenance needs, resulting in an optimized repair schedule and a 25% decrease in customer calls. Additionally, a reduction in crashes and tort claims can also be reasonably expected due to the improved pavement conditions and faster repairs.
This slide illustrates the Work Zone Traveler Information application that was selected to improve work zone planning and management. The projected impacts include a 30% increase in travel time reliability and an 80% crash reduction resulting from improved work zone management strategies; improved traveler information regarding the work zone; improved flexibility regarding travel-route alternatives, and improved mobility and worker safety resulting from fewer vehicles traveling through work zones.
In closing, this slide illustrates the fully integrated application deployment concept for District 13 operations. The overall goal of improving the efficiency year-round of road maintenance in District 13 has been achieved. Data from vehicles and infrastructure is sent to the Traffic Management Center (TMC) and used to provide information to both passenger cars and maintenance fleets. State maintenance vehicles also act as probes for road-weather data, congestion data, and pavement data, and TMCs can use the data in a variety of value-added applications.
