TRB released a straight-to-recording series in April that presents highlights and findings of the NCHRP Domestic Scan 16-02 on Landscape Design Practices for Roadside Water Management . This scan investigated how transportation agencies are applying principles and practices of green infrastructure (GI) for roadside water management to mitigate adverse impacts of flooding, drought, and temperature extremes affecting their infrastructure. The videos are available on-demand at no charge. Presenters: Garrett...

Public-use airports, metropolitan planning organizations (MPOs), and local land-use/ transportation planning agencies all have independent yet interrelated planning processes bound by legal and policy requirements to ensure compatibility. This means that they should work cooperatively to solve joint transportation challenges in the most effective and efficient manner. The TRB Airport Cooperative Research Program's ACRP Research Report 216: Guidebook for Assessing Collaborative Planning Efforts Among Airp...

Now available to order from the TRB Bookstore, the Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis (HCM) provides methods for quantifying highway capacity. In its current form, it serves as a fundamental reference on concepts, performance measures, and analysis techniques for evaluating the multimodal operation of streets, highways, freeways, and off-street pathways. The Sixth Edition incorporates the latest research on highway capacity, quality of service, Active Traffic...

Many airports undertake stormwater projects to accommodate facility expansion, address obsolescence, and respond to evolving regulatory requirements. Often, stormwater infrastructure is installed or upgraded on a project-by-project and piecemeal basis, resulting in mismatches of sizes, material types, ages, and conditions. When airports are considering expanding or improving their stormwater facilities, the immediate need for stormwater infrastructure modification may not be clear, and a benefit–cost ana...

Incompatible land uses can threaten the safe utility of airports and expose people living and working nearby to potentially unacceptable levels of noise or safety risk. At the state level, all 50 states have enacted some form of airport zoning legislation since the 1950s. The majority of states (90 percent) have enacted laws mandating or enabling local governments to adopt, administer, and enforce airport zoning regulations. The TRB Airport Cooperative Research Program's ACRP Research Report 206: Guidebo...

TRB's Transit Cooperative Research Program (TCRP) has issued a request for proposals to develop a guide for public transportation agencies and concerned stakeholders on effective approaches and best practices that are responsive to people who are experiencing homelessness. This project is intended to help public transportation agencies preserve the quality of their services and facilities, while respecting the rights and mobility needs of people experiencing homelessness, including the need for safe plac...

In the Columbus City Schools, Ohio's largest school district, 62% of students have the required technology to learn online. The district is not alone. Schools around the state are on the hunt for online resources to close the gap -- and turning to corporate America and the public for help.

TRB's Transit Cooperative Research Program (TCRP) has issued a request for proposals to develop a comprehensive, evidenced-based guide for bus operator workforce management from pre-employment through retirement. The guide should present both best practices and innovative practices that enhance and sustain public transit and support bus operators who provide fixed-route, flexible-route, and on-demand services. Proposals are due August 11, 2020 at 5:00 PM Eastern.

Airports are using tools that help them identify risks within their environment. Most airports are providing a means to report risk. Smaller airports use low-cost options such as email, a 24/7 phone number, or a suggestion box. Larger airports have embraced safety management or enterprise risk management programs that include more expensive reporting and tracking systems. The TRB Airport Cooperative Research Program's ACRP Synthesis 106: Airport Risk Identification and Prioritization Practices provides i...

How do transportation agencies apply principles of green infrastructure (GI) to roadside water management? TRB is hosting a webinar on Monday, May 18, 2020 from 2:00 to 3:30 PM Eastern that aims to answer this question. Presenters will identify how GI may be used to mitigate impacts of flooding, drought, and temperature extremes that affect infrastructure. This webinar draws on research from the National Cooperative Highway Research Program (NCHRP) Domestic Scan Program 16-02: Leading Landscape Design Pr...

TRB's Airport Cooperative Research Program (ACRP) Research Report 155: Guidebook for Advanced Computerized Maintenance Management System Integration at Airports explores the use of a Computerized Maintenance Management System (CMMS) to manage a variety of assets across a number of different airport systems. This report develops guidance on the steps necessary to implement a CMMS, factors for consideration in prioritizing which systems should be included in the CMMS using a phased approach, and the steps ...

“Pavement condition data” are essential inputs to the process of managing airport pavements and ensuring safe operations. The technology available today to collect pavement condition data is considerably different from that available even 20 years ago, and new technologies are being developed and introduced into practice at a rapid pace. ACRP Research Report 203: Guidelines for Collecting, Applying, and Maintaining Pavement Condition Data at Airports provides guidance on the collection, use, maintenance,...

Airports worldwide are setting aggressive zero- or low-emissions targets. To meet these targets, airports are deploying new strategies, adopting innovative financing mechanisms, and harnessing the collective influence of voluntary emissions and reporting programs. In tandem, new and affordable zero- or low-emissions technologies are rapidly becoming available at airports. The TRB Airport Cooperative Research Program's pre-publicaton draft of ACRP Research Report 220: Guidebook for Developing a Zero- or L...

The first edition of this report, in 2009, provided a comprehensive industry reference for the management of airport deicing runoff. The second edition has been wholly updated to reflect the latest industry practices. The TRB Airport Cooperative Research Program's ACRP Research Report 14: Deicing Planning Guidelines and Practices for Stormwater Management Systems, second edition , explores a wide array of practices designed to provide for the practical, cost-effective control of runoff from aircraft and ...

TRB’s Airport Cooperative Research Program (ACRP) Research Report 16: Guidebook for Managing Small Airports. Second Edition is designed to help airport practitioners, owners, operators, managers, and policymakers of small airports, who may have varying degrees of experience and backgrounds, to fulfill their responsibilities in such areas as financial management, oversight of contracts and leases, safety and security, noise impacts, community relations, compliance with federal and state obligations, facil...
