With a quick search online, 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 Research Report 947: Implementing Information Findability Improvements in State Transportatio...

Management of traffic signal systems is a critical function for every transportation agency.  Thanks to advancements in technology, it is now possible to collect large amounts of data at signalized intersections, leading to the development of dozens of performance measures. The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 954: Performance-Based Management of Traffic Signals provides information to help agencies invest in signal performance measu...

State transportation agencies will always fulfill a role in the emergency-management effort - for all incidents, from the routine traffic incident through major emergencies to catastrophic events. State agency plans and procedures are expected (indeed required if the agency seeks federal compensation) to be related to state and regional emergency structures and plans. This involves multi-agency, multi‐jurisdictional cooperation in emergency planning and operations. The TRB National Cooperative Highway Re...

Since 2009, when NCHRP's last Security 101 report was released, there have been significant advances in transportation security approaches, including new strategies, programs, and ways of doing business that have increased the security of transportation systems as well as ensured their resiliency. Hazards and threats to the system have also continued to evolve since 2009. While the incidence of large-scale terrorist attacks has remained small, transportation agencies are at increasingly greater risk...

Integrated Corridor Management (ICM) is a relatively new congestion management approach that has been gaining interest for its potential to mitigate congestion with few changes to the existing transportation infrastructure. The TRB National Cooperative Highway Research Program's NCHRP Research Report 899: Broadening Integrated Corridor Management Stakeholders addresses a broad range of operational and efficiency issues that are critical to bringing non-traditional (freight, transit, incident response, an...

The past decade has been characterized by the pressing need to rapidly renew the nation’s deteriorating infrastructure, which has driven the increased use of alternative contracting methods for transportation and other infrastructure projects. The TRB National Cooperative Highway Research Program's NCHRP Research Report 937: Guidebook for Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods is designed to help guide alternative technical concepts (ATCs) in the stat...

The U.S. Department of Transportation has essential requirements for researchers and research institutions requesting and receiving transportation-related federal research funds. The U.S. DOT strives to make it easier to publish and communicate scientific knowledge. It is a long-range vision which goes beyond the requirements of the U.S. DOT’s Public Access Plan. The TRB National Cooperative Highway Research Program's NCHRP Research Report 936: Guide to Ensuring Access to the Publications and Data of Fed...

Extreme weather events and a changing climate increasingly boost costs to transportation agencies and to the traveling public. While Departments of Transportation (DOTs) are taking into account changing climate and extreme weather when making infrastructure decisions, they typically are not using a formal set of tools or cost-benefit analyses (CBAs) to address climate resilience because they may be too time-consuming and expensive to conduct routinely. The TRB National Cooperative Highway Research Progra...

With increased connectivity between vehicles, sensors, systems, shared-use transportation, and mobile devices, unexpected and unparalleled amounts of data are being added to the transportation domain at a rapid rate, and these data are too large, too varied in nature, and will change too quickly to be handled by the traditional database management systems of most transportation agencies. The TRB National Cooperative Highway Research Program's NCHRP Research Report 952: Guidebook for Managing Data from Em...

The findings of this survey report show that providing light beyond the limits of the roadway travel lanes benefits drivers’ visual performance and that the spectral content of light-emitting diode (LED) sources should be a design consideration. The study also found that, at present, there are no health impacts from properly designed roadway lighting. The TRB National Cooperative Highway Research Program's  NCHRP Research Report 940: Solid-State Roadway Lighting Design Guide: Volume 2: Research Over...
