Transportation management plans (TMPs) are a set of coordinated strategies designed to help agencies achieve work zone project goals related to traffic mobility, efficient system operation, motorist and worker safety, and other operational targets. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 276: Evaluating Strategies for Work Zone Transportation Management Plans focuses on the field evaluations that are part of NCHRP Research Report 945: Strategies for Work Zone Trans...

New definitions will help pavement cracking survey providers and pavement engineers at state highway administrations conduct objective cracking measurements and encourage continuing technological innovations by researchers and vendors. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 288: Standard Definitions for Common Types of Pavement Cracking helps develop standard, discrete definitions for common cracking types for asphalt and concrete pavements. The standard definitio...

Integrated Corridor Management (ICM) is an operational concept that seeks to reduce congestion and improve performance by maximizing the use of available multimodal capacity across a corridor, including highways, arterial roads, and transit systems. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 287: Planning and Implementing Multimodal, Integrated Corridor Management: Guidebook provides an overview of current recommended practices and outlines critical components for the...

Few resources provide information related to selecting the most appropriate traffic signal phasing for the various geometric and operational situations encountered in the field. This is especially true for left-turn signal phasing decisions with respect to the level of control for the left-turn movement and whether left turns should precede or follow the main through movement. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 284: Decision-Making Guide for Traffic Signal Pha...

With a quick online search, you can discover the answers to all kinds of questions. Findability within large volumes of information and data has become almost as important as the answers themselves. Without being able to search various types of media ranging from print reports to video, efforts are duplicated and productivity and effectiveness suffer. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 279: Information Findability Implementation Pilots at State Transportation ...

Transportation plays a critical role in emergency management. After all, state transportation agencies have large and distributed workforces, easy access to heavy equipment, and a robust communications infrastructure capable of sustained mobilization. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 267: Developing a Guide to Emergency Management at State Transportation Agencies is a supplemental report to NCHRP Research Report 931: A Guide to Emergency Management at State ...

Small events pose threats of great consequences since the impact of any incident is magnified when a transportation network is operating at or past its capacity—as is the case in portions of many states as travel demand on their transportation networks grows. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 266: Developing a Physical and Cyber Security Primer for Transportation Agencies is a supplemental document to NCHRP Research Report 930: Update of Security 101: A Physi...

There is an emerging view in the construction industry that better performance or better value for money can be achieved by integrating teamwork for planning, design, and construction of projects. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 277: Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods seeks to assist integrated construction projects to include the construction contractor in the design process in some meaningful manne...

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 270: Developing a Guide to Ensuring Access to the Publications and Data of Federally Funded Transportation Research  provides guidance for state departments of transportation (DOTs) to help them meet the requirements of the U.S. DOT Public Access Plan requiring preservation of the products of all federally funded transportation research. The document is released in parallel with  NCHRP Research Report 936: Guide to ...

Cost-benefit analysis (CBA) is useful for climate change response and adaptation, and if used properly, it has great potential for long-range planning. CBA should help agencies navigate the spectrum of decisions from mitigation and greenhouse gas reduction to adaptation: where does investing public funds generate the most public good? The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 271: Guidelines to Incorporate the Costs and Benefits of Adaptation Measures in Preparation ...
