TCRP Research Report 265: Addressing Travel Needs of Women and Families on Public Transportation | Guide/Manual, Research Report
Accessibility, Organizational Management, System PerformanceMany women’s travel experiences relate directly to their disproportionate share of caregiving responsibilities. Travelers supervising dependents are more likely to need access to multiple destinations and may have more belongings in tow. Because dependents are unlikely to be commuting adults, travel during off-peak hours is more common, and paying multiple fares can increase the financial burden. Additionally, safety is a greater concern for women, both when they are traveling alone and when they are traveling with dependents, especially children.
TCRP Research Report 265: Addressing Travel Needs of Women and Families on Public Transportation, produced by TRB’s Transit Cooperative Research Program, presents a set of practical tools to help transit agencies better understand their riders, use existing data more effectively, assess how well they are serving women and families, build internal support for these efforts, and identify service planning, vehicle, and station design strategies that benefit women and families. The eight tools are organized into three stages: Understand Your Riders, Build Internal Capacity, and Deploy Your Tactics.
NCHRP Research Report 1180: Depicting Utility Facilities in Design Plans: A Guide | Guide/Manual
Asset ManagementSubsurface utilities, buried from inches to many feet below roadways and rights-of way, pose significant challenges because they are not visible and cannot be assessed through visual inspection. Their location, condition, ownership, and impact on cost and schedule must instead be determined through specialized investigation methods and stakeholder coordination. Utility data depiction is the primary means of communication, yet it is often inconsistent, with varying stakeholder expectations.
NCHRP Research Report 1180: Depicting Utility Facilities in Design Plans: A Guide, produced by TRB’s National Cooperative Highway Research Program, provides a set of guidelines for transportation agencies on depicting utility data from various sources. These guidelines support design decision-making, utility conflict identification and resolution, and consistent depiction practices. The scope includes both existing and proposed utility facilities. The guide is intended to support both 2-D and 3-D formats, recognizing that agencies vary in their access to and proficiency with different software tools.
The same project that developed NCHRP Research Report 1180 also produced NCHRP Web-Only Document 449: Developing a Guide to Depicting Utility Facilities in Design Plans. This companion document summarizes the research conducted to develop the guide.
NCHRP Research Report 1179: Overcoming Barriers to Implementing Research Outcomes | Research Report
Organizational ManagementA myriad of common barriers can hinder research projects from achieving implementation. Within transportation agencies, many of these barriers are associated with organizational challenges, disconnected research outcomes, and workforce constraints. Organizational challenges arise from structures and processes that may not support effective research implementation. Disconnected research outcomes can lead end users to be unwilling to adopt those outcomes in their daily practice. Workforce constraints related to research implementation may involve staff capacity, skill sets, and levels of interest within both the agency’s research department and among the intended beneficiaries of the research outcomes.
NCHRP Research Report 1179: Overcoming Barriers to Implementing Research Outcomes, produced by TRB’s National Cooperative Highway Research Program, provides a toolkit of strategies to improve the implementation of research outcomes and maximize their impact. The toolkit introduces a common language for describing research and its implementation and presents a series of frameworks that demonstrate alternative approaches to implementation planning. It also outlines strategies for overcoming the most commonly cited barriers to implementing research outcomes.
TCRP Synthesis 188: Red-Tinted Bus Lane Experience | Research Report
Asset Management, Pavement, System PerformanceRed-tinted bus lanes are defined as lanes featuring red-colored pavement intended to enhance the visibility of locations, station stops, or travel lanes reserved exclusively for public transit vehicles or multimodal facilities where public transit is the primary mode. Although red-tinted bus lanes have been implemented in several cities, there is relatively limited documentation on their impacts, operational challenges, and other information valuable to agencies interested in implementing them.
TCRP Synthesis 188: Red-Tinted Bus Lane Experience, produced by TRB’s Transit Cooperative Research Program, documents the current state of practice for the implementation and performance of red-tinted bus lanes in North America. The report addresses topics such as planning, design, and implementation; materials; operations and enforcement; and system impacts. It also provides guidance and lessons learned from agencies that have implemented and operate red-tinted bus lanes.
Transit Capacity and Quality of Service Manual, 4th edition | Document
Throughout its more than 25-year history, the Transit Capacity and Quality of Service Manual (TCQSM) has compiled the state of the practice based on peer-reviewed research published by the Transportation Research Board and others. The TCQSM provides transportation practitioners of varying levels of experience and responsibility information, techniques, and resources to support the planning, design, and operation of transit services, facilities, and systems. While the TCQSM’s methods represent the best available knowledge at the time of publication, they do not establish policies regarding desirable or appropriate levels of quality of service or capacity for transit services, facilities, or systems.
TCRP Research Report 262: Transit Capacity and Quality of Service Manual, 4th edition, includes updated statistics, transit agency application examples, and photographs. The manual incorporates emerging mobility options such as microtransit and low-speed automated vehicles, with expanded coverage of widely adopted technologies such as bus and ferry electrification. This edition updates key concepts related to modes and services, operations, and quality of service. Additional updates address topics including quality of service measures and applications, bus transit, demand-responsive transit, rail transit, ferry transit, and transit stops and stations.

Making CAV Deployments Compatible with Complete Streets Objectives for Safe and Efficient Operation Phase II | Research Report
Accessibility, Equity, Safety, System PerformanceThis research presents a quantitative framework to help agencies evaluate trade-offs between safety, efficiency, and equity when redesigning urban streets for multimodal operations and connected/automated vehicle (CAV) integration. The study introduces two complementary tools: a Network Fundamental Diagram (NFD)-based optimization model for system-level performance planning and a multi-agent simulation platform that evaluates real-world interactions among vehicles, pedestrians, cyclists, micromobility, and emerging modes.
Practitioners will gain insight into how to move beyond qualitative Complete Streets guidance by applying measurable objectives—including accessibility gaps, sufficiency thresholds, and maximin equity principles—to corridor and network design. The framework also incorporates advanced safety metrics (e.g., Time-to-Collision and impact severity) to evaluate both conflict likelihood and consequence. Case studies demonstrate how agencies can transparently compare design alternatives and make evidence-based decisions when trade-offs are unavoidable.

PIARC: Impact of the Development of Active Transport Modes in Road Tunnels – Current Situation Report and Case Studies | Research Report
Accessibility, Equity, Mobility, Safety, System PerformancePIARC: Impact of the Development of Active Transport Modes in Road Tunnels – Current Situation Report and Case Studies examines the growing integration of active transportation modes—such as pedestrians, cyclists, and other vulnerable road users—within road tunnel environments. As cities seek to improve mobility, accessibility, and emissions outcomes, tunnel owners and operators face new safety, design, and operational challenges when authorizing active modes in these confined facilities. This international report compiles and evaluates case studies from around the world, highlighting how tunnels are being constructed or retrofitted to safely accommodate active users through infrastructure adaptations, equipment upgrades, and revised operational procedures.
The document categorizes examples into four approaches: tunnels with safety galleries usable by active modes, tunnels with protected spaces for active users, tunnels with specific geometric or operational adaptations, and tunnels dedicated entirely to active mobility. Drawing on global expert contributions, the report outlines the state of practice and identifies key considerations for safety, risk management, and coordination with emergency services. It provides a foundation for future recommendations to guide decision-making by tunnel owners, designers, safety professionals, and transportation agencies considering active mode integration.
Analysis and Recommendations for Calculating Reimbursement Eligibility Levels for Utility Relocations | Research Report
Asset ManagementThe Texas Department of Transportation (TxDOT) spends hundreds of millions of dollars on utility relocations every year. Of the various situations in which a utility relocation is eligible for reimbursement, one of the most complex situations is when parts of the existing utility facility involve a property interest because the utility owner either has an easement or owns the property in fee simple. A wide range of practices exist for what constitutes eligibility for reimbursement.
The purpose of this research was to review and provide recommendations on the methodologies TxDOT uses to determine reimbursement eligibility and calculate utility reimbursement amounts. The research team conducted a review of national practices that included an analysis of relevant laws, regulations, and manuals, as well as interviews with state department of transportation officials. The research team conducted an analysis of a sample of utility agreements at TxDOT, including a review of reimbursement costs and reimbursement eligibility calculation methodologies, and prepared recommendations for implementation. The recommendations include strategies to consider for the calculation of eligibility ratios as well as strategies to improve the quality of utility agreements to make the review and approval process more consistent, accurate, and reliable.
