The North Carolina Department of Transportation (NCDOT) proposes to evaluate, demonstrate, and promote advanced technology for collaboration among the Statewide Transportation Operations Center (STOC), Traffic Management Centers (TMCs), Incident Management Assistance Patrol (IMAP) Responders, and other partner agencies. These innovations are intended to improve situational awareness as well as incident response and clearance times. By performing a best-use study, the NCDOT can better understand the capabilities of these technologies and how they can improve the NCDOT’s capabilities. Results of the evaluation will be used in the demonstration and promotion of these innovative collaboration technologies. STIC funds will be used to assess, pilot, and investigate the capabilities, requirement, and limitations of the collaboration technologies. Ultimately, a recommendation will be made on how the NCDOT should implement and use the technologies.
In 2016, 72% of nationwide pedestrian fatalities occurred away from intersections (e.g. mid-block locations) and 26% at intersections. Several cost-effective countermeasures can be systematically applied to reduce crashes and save lives by using temporary materials. Temporary materials are valuable in broadening exposure to specific solutions and developing state data of their effectiveness in improving pedestrian safety.
This program would launch the creation of a tactical materials library and deployment selection tool for temporary bicycle and pedestrian countermeasures related to FHWA's Safe Transportation for Every Pedestrian (STEP) program.
The deployment selection tool will aid communities in identifying the appropriate countermeasure that addresses the specific location and safety concern. The selection tool will form the foundation for a deployment request of library materials, which will include a site-specific analysis to measure safety impact and evaluate the need and benefit of permanent improvements.
The NCDOT Hydraulics Unit proposes to review, update and transform business-critical information into "living documents" compatible with the latest information technologies and innovative practices. Major goals inlcude, but are not limited:
-Holding peer exchanges with other state DOT's to identify innovative practices, such as two-dimensional hydralic modeling, resilient design techniques, flood inundation visualization, etc for implementation to improve both hydraulic design quality and efficient project delivery
-Developing context-sensitive guidance to facilitate the end user's efficiency in applying risk-informed, performance-based approaches to hydraulic design
-Updating the format of how guidcance is provided to reflect the state-of-the-practice, leveraging new web-based and digital technologies where they can be more effective than conventional printed media.
The North Carolina Department of Transportation (NCDOT) is requesting STIC Incentive funding to study, demonstrate, and promote a tow and recovery project related to the Business 40 Improvement Project. This innovation is intended to improve incident response and clearance times on the roadway network that is impacted by this major construction project. Performance measures and incentives are expected to help clear the roadway of incidents faster than the current practice of using the local rotational tow contracts. Analysis results of the towing contract performance will be used in the demonstration and promotion of this innovative traffic management tool. STIC funds will be used to collect and analyze data and produce a final report including recommendations for future similar programs.
NCDOT will let a special tow contract for the Business 40 Improvements Project, expected to begin November 2018. Current analysis of tow arrival times (preconstruction) shows approximately 35-40 minutes on average. The tow contract will include a benchmark arrival time based on the severity of the crash/incident. NCDOT needs an evaluation method to determine how effective this special tow contract is in order to consider similar contracts on future large construction projects.
The Transportation Planning Division and Bicycle and Pedestrian Transportation Division are introducing new, innovative practices to NCDOT’s long range transportation planning process to support a linkage between project identification in the long range transportation process to project prioritization specifically focused on multi-modal projects that support better integration of bicycle and pedestrian facilities with highway improvements multi-modal projects that support better integration of bicycle and pedestrian facilities with highway improvements through a peer-to-peer exchange.
This project will benefit NCDOT, MPOs, RPOs and local government partners across the state by identifying innovative methods in long range planning that can be replicated to improve the way bicycle and pedestrian mode considerations are integrated into long range transportation plans and provide strategies for identifying projects that address the needs of all roadway users in long range transportation plans, corridor plans and mode-specific plans. The divisions are seeking planning innovations that support the delivery of a suite of transportation projects that enhance overall mobility.
The NC Strategic Highway Safety Plan includes bicycle and pedestrian travel as an emphasis area and NC is considered a FHWA pedestrian and bicycle focus state. Therefore, the NCDOT is developing and implementing course modules for a new training, tentatively titled: A Collaborative Approach to Advance Complete Streets, in response to the EDC STEP, Safe Transportation for Every Pedestrian initiative. This course will be delivered in six 1-day training events and target key strategies for complete streets initiatives with regards to pedestrian safety. The request will focus on the training and understanding of complete streets as well as the pedestrian and bicyclist countermeasures as they relate to Complete Streets, visibility and awareness of the user, traffic law enforcement, and encouraging statewide participation in safety campaigns and planning proposals while evaluating and improving the project outcomes.
Automated Traffic Signal Performance Measures (ATSPM) using High Resolution Data provides for the continuous collection and monitoring of signal timing performance and improvements in the process of signal timing based on actual performance data. Since signal system timing is a manual process in NC, use of high resolution data to automate traffic signal performance measures could potentially increase the efficiency and effectiveness of signal timing. Investigation of ATSPM is part of a larger project to explore continuous traffic data options to support a data-driven approach to selection of corridors for retiming that maximizes the return on investment of the dedicated signal system optimization funding. STIC funds will be used to develop an implementation plan and produce a final report including recommendations for performance measures and system process changes.
The NCDOT Ferry Division fleet is paramount to ensuring connectivity for the coastal areas where the routes serve as an extension of the highway system. The fleet includes twenty-one (21) ferries traversing seven (7) routes along the coast. In addition, the Ferry Division’s marine maintenance fleet maintains the routes and landing areas to ensure safe operating condition. The ferries are procured in part under NCDOT’s Strategic Transportation Investment (STI) Program. A part of the Ferry Division’s operational charge is to maintain these assets to an exceptional high level of service while doing so in the most responsible and fiscally responsible manner. In order to best make these determinations, we are constantly trying to refine and improve our asset management practices in order to make the best and most fiscally responsible decisions possible.
The Ferry Division’s asset management plan continues to evolve and improve as we move forward in using asset management practices to make the best decisions in regards vessel maintenance, repair, and replacement. As the age of our ferry assets increases, the Ferry Division Shipyard no longer has the manpower necessary to keep up with the repair and maintenance needs on our assets across the fleet. Consequently, we are beginning to contract to private shipyards some of the work to improve the condition of our assets that has traditionally been performed in house.
In order to move forward with applying asset management to our fleet and maximizing the benefit of this step, the Ferry Division proposes a project to develop updated maintenance standards and specifications for all classes and types of floating equipment within the NCDOT Ferry System. The standards and specifications will include protocols for preventive maintenance, as applies to USCG mandated credited dry docks, as well as repair work. By having these innovative standards and specifications, we will be able to accurately and directly compare the cost and time of contracted work against our own in house costs. The development and implementation of the standards and specifications will allow us to make accurate business and economic analyses in regards to contracting procedures and workload management. This in turn improves our asset management practices and allows us to put in place a process improvement that will improve the level of service for the fleet and help us get the best benefit out of our limited funding.
The bump at the beginning or end of a bridge is a serious safety issue and a common problem on North Carolina Department of Transportation (NCDOT) bridges. Several years ago there was even a traffic fatality in eastern North Carolina attributed to a settling bridge approach slab. This STIC project involved deep compaction grouting to stabilize settling bridge approach embankments and slabs and restore the grade of the approach slabs for the dual bridges on Cary Parkway over the Norfolk Southern Railroad in Cary, NC. The bridges were constructed in 2001 and the failing bridge approach slabs continued to settle creating maintenance issues and citizen complaints.

The Local Programs Management Office (“LPMO”) within the North Carolina Department of Transportation was interested in exploring development of a certification program that would allow Local Public Agencies (LPAs) to assume some of the responsibilities for locally administered projects currently assigned to the Department. The certification program would help the Department and LPAs determine if the LPAs meet requirements to administer federal-aid projects and ensure they have the expertise and process necessary to meet these requirements. The Department would benefit from the reduced oversight of LPAs that would be certified to administer projects.
