Multi-vehicle mobile operations on two-lane two-way roadways present unique challenges to highway agencies, not the least of which is the highly variable conditions encountered in the field. These conditions include the number of vehicles in the work convoy, travel speed of the work convoy, posted speeds, roadway geometry, time of day, weather, and average daily traffic on the roadway. Highway agencies are therefore challenged with developing temporary traffic control (TTC) procedures that ensure safe and effective operations under these highly variable conditions.
Highway workers face many hazards during mobile operations on two-lane roadways. From 2003 through 2015, 1,571 workers lost their lives at road construction sites (Centers for Disease Control and Prevention, 2017). Many of these hazards are a direct result of motorists driving behaviors when encountering a work convoy. Examples of this behavior includes erratic driving, speeding, entering the convoy, failure to follow signage (which may be due to misunderstanding traffic control devices), impatience with the delay caused by the slower speed of the mobile operation, and distracted driving. Temporary traffic control for most mobile operations has been limited to arrow panels and static warning signs mounted on the back of work vehicles, which may be misunderstood by motorists. Research is needed to enhance the safety of mobile operations by reducing opportunities for poor driver decisions through the use of safer and more effective temporary traffic control procedures.
The objective of this research is to develop guidance to enhance safety and effectiveness of mobile operations on two-lane, two-way roadways under variable conditions. The guidance should address all aspects of mobile operations from planning (when to use mobile operations vs. other methods for lane closures) through implementation, and be useable by any entity involved in mobile operations.
The research should address a broad range of issues related to enhancing safety and effectiveness of mobile operations on two-lane, two-way roads, such as, but not limited to the following:
- Definition and classification of mobile operations by their context (e.g., type of work, extent of the work, time of day, posted speed and speed of convoy, terrain, roadway geometry, traffic volume);
- Summaries of the state-of-practice, both nationally and internationally, for safe and effective mobile operations on two-lane two-way roadways;
- Descriptions of the challenges encountered when implementing safe and effective mobile operations on two-lane two-way roadways;
- Recommendations for improving traffic control signage and communication consistency;
- Methods for adapting to differing site conditions during a single mobile operation (e.g., intersections, rail grade crossings, pedestrian and bicycle facilities, on-street parking);
- Techniques for reducing the potential of work zone intrusions and end of queue crashes by motor vehicle operators; and
- Methods used to validate the safety and effectiveness of the guidelines.
The NCHRP is seeking the insights of proposers on how best to achieve the research objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective.
A kick-off teleconference of the research team and NCHRP shall be scheduled within 1 month of the contract’s execution. The work plan proposed must be divided into tasks, with each task described in detail. There must be an interim report and a face-to-face meeting scheduled with NCHRP to discuss the interim report and a peer exchange webinar to review the draft final guidelines. The project schedule shall include 1 month for NCHRP review and approval of the interim report.
The final deliverables will include: (1) guidance to enhance the safety and effectiveness of mobile operations on two-lane two-way roadways under variable conditions; (2) a final report documenting the entire project, incorporating all other specified deliverable products of the research; (3) an electronic presentation of the research, highlighting the guidance; (4) recommendations, needs, and priorities for additional related research; and (5) a stand-alone technical memorandum titled “Implementation of Research Findings and Products” (see Special Note B for additional information).
Note: Following receipt of the draft final deliverables, the remaining 3 months shall be for NCHRP review and comment and for research agency preparation of the final deliverables.
A. Proposals should include a task-by-task breakdown of labor hours for each staff member as shown in Figure 4 in the brochure, "Information and Instructions for Preparing Proposals" (http://onlinepubs.trb.org/onlinepubs/crp/docs/ProposalPrep.pdf). Proposals also should include a breakdown of all costs (e.g., wages, indirect costs, travel, materials, and total) for each task using Figures 5 and 6 in the brochure. Please note that TRB Cooperative Research Program subawards (selected proposers are considered subawards to the National Academy of Sciences, the parent organization of TRB) must comply with 2 CFR 200 – Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards. These requirements include a provision that proposers without a "federally" Negotiated Indirect Costs Rate Agreement (NICRA) shall be subject to a maximum allowable indirect rate of 10% of Modified Total Direct Costs. Modified Total Direct Costs include all salaries and wages, applicable fringe benefits, materials and supplies, services, travel, and up to the first $25,000 of each lower-tier subaward and subcontract. Modified Total Direct Costs exclude equipment, capital expenditures, charges for patient care, rental costs, tuition remission, scholarships and fellowships, participant support costs and the portion of each lower-tier subaward and subcontract in excess of $25,000.
B. The NCHRP is a practical, applied research program that produces implementable products addressing problems faced by transportation practitioners and managers. The benefits of NCHRP research are realized only when the results are implemented in state DOTs and other agencies. Implementation of the research product must be considered throughout the process, from problem statement development to research contract and beyond completion of the research. Item 4(c), "Anticipated Research Results," must include the following: (a) the "product" expected from the research, (b) the audience or "market" for this product, (c) a realistic assessment of impediments to successful implementation, and (d) the institutions and individuals who might take leadership in deploying the research product. The project panel will develop and maintain an implementation plan throughout the life of the project. The research team will be expected to provide input to an implementation team consisting of panel members, AASHTO committee members, the NCHRP Implementation Coordinator, and others in order to meet the goals of NCHRP Active Implementation: Moving Research into Practice, available at http://onlinepubs.trb.org/onlinepubs/nchrp/docs/NCHRP_ActiveImplementation.pdf.
C. Item 5 in the proposal, "Qualifications of the Research Team," must include a section labeled "Disclosure." Information relevant to the NCHRP's need to ensure objectivity and to be aware of possible sources of significant financial or organizational conflict of interest in conducting the research must be presented in this section of the proposal. For example, under certain conditions, ownership of the proposing agency, other organizational relationships, or proprietary rights and interests could be perceived as jeopardizing an objective approach to the research effort, and proposers are asked to disclose any such circumstances and to explain how they will be accounted for in this study. If there are no issues related to objectivity, this should be stated.
D. Proposals are evaluated by the NCHRP staff and project panels consisting of individuals collectively very knowledgeable in the problem area. Selection of an agency is made by the project panel considering the following factors: (1) the proposer's demonstrated understanding of the problem; (2) the merit of the proposed research approach and experiment design; (3) the experience, qualifications, and objectivity of the research team in the same or closely related problem area; (4) the plan for ensuring application of results; (5) the proposer's plan for participation by Disadvantaged Business Enterprises--small firms owned and controlled by minorities or women; and (6) the adequacy of the facilities.
Note: The proposer's plan for participation by Disadvantaged Business Enterprises should be incorporated in Item 12 of the proposal.
