The amount of data surrounding the application of emerging technologies is expanding, producing “big data” at magnitudes not previously seen. While a few agencies have found some success with individual projects, most are uncertain on how to handle this level of big data at an organizational level. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 282: Framework for Managing Data from Emerging Transportation Technologies to Support Decision-Making is designed to walk an agen...

The procedures detailed in the 6th Edition of the Highway Capacity Manual (HCM) estimate capacity and several operational measures, including those determining Level of Service, for freeway facilities as well as surface streets. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 290: Highway Capacity Manual Methodologies for Corridors Involving Freeways and Surface Streets introduces materials to help modify the freeway analysis methods and the urban street methods so that th...

State Departments of Transportation (DOTs) and other government agencies recognize the value of connected vehicle (CV) technologies in helping achieve the strategic objectives of saving lives and relieving congestion. Several agencies are currently planning and preparing for a future where CV technologies could become a part of their routine business operations. A core consideration in any such planning effort is an assessment of the need for and the nature of public CV infrastructure investments to supp...

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...

While not all right-sizing projects involve a change in jurisdictional responsibility and ownership, jurisdictional transfer can be a key tool for implementing right-sizing plans and agreements. As a supplemental document to NCHRP Research Report 917: Right-Sizing Transportation Investments:A Guidebook for Planning and Programming , the TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 263: White Papers for Right-Sizing Transportation Investments offers practical examples of the...

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 ...
