Prior to this research project, state highway agencies did not have tools for reflecting safety in their decisions concerning freeway and interchange projects. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 306: Safety Prediction Methodology and Analysis Tool for Freeways and Interchanges documents a safety prediction...

A primary requirement of the transport system is for efficient evacuation routes and associated facilities such as signage that will enable people to move safely and quickly away from hazards and major impacts. Thus there is a need to be able to design, assess and be confident in the efficacy of proposed evacuation routes.  Through this research, an...

Pavement preservation is broadly acknowledged to provide network-wide benefits such as extending pavement life, enhancing system performance, reducing operation and maintenance costs, and improving safety. However, the performance of each pavement preservation project hinges on many factors. The TRB National Cooperative Highway Research Program's NCHRP...

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 302: Development of a Comprehensive Approach for Serious Traffic Crash Injury Measurement and Reporting Systems presents a roadmap for states to develop comprehensive crash-related data linkage systems, with special attention to measuring serious injuries in crashes. The full...

Traffic-associated fatigue damage is one of the major distresses in which flexible pavements fail. This type of distress is the result of many thousands—or even millions of wheel loads passing over a pavement. The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 982: Relationships Between the Fatigue...

This report highlights findings from Phase I of a project designed to evaluate the ruggedness of the standards for cyclic fatigue testing using an Asphalt Mixture Performance Tester (AMPT). These standards include AASHTO TP 107-18 and 133-19, which are applicable to 100-mm diameter and 38-mm diameter test specimens, respectively. The ruggedness evaluation...

Every year MDOT invests millions of dollars into testing geomaterials, digitizing historic records and capturing inventory and condition data. Massive amounts of tabular data, documentation and imagery, which are relevant for planning and engineering purposes, continue to be accumulated. The engineering characteristics of pavement or other materials can be...

This resource is intended to inform discussions about on-street parking and bikeway selection. It is a supplementary resource to the FHWA Bikeway Selection Guide. It begins with a discussion of on-street parking and bikeway types, with associated dimensional requirements and trade-off considerations. It then presents several strategies involving choices...

This guide is intended to support agencies that are interested in conducting pedestrian-  and bicycle-focused RSAs and includes information on safety risks for both modes, the RSA process, necessary data, and the roles and responsibilities of the RSA Team. Also included are updated prompt lists for pedestrians and bicyclists to use in the field. This guide...

The roughness experienced at bridge approaches and departures, generally termed the bump at the end of the bridge (BEB), has been identified as one of the most prominent issues in the transportation industry. The BEB is usually detected qualitatively based on road user feedback, with maintenance strategies subsequently implemented to improve ride quality. The...

Several controlled laboratory studies have shown that air voids (AV) can have a large effect on the performance of asphalt pavements. AVs that are either too high or too low can cause a reduction in pavement life. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 299: Investigating the Relationship of As-Constructed Asphalt...

The ability to accurately predict vehicle trajectories is essential in infrastructure-based safety systems that aim to identify critical events such as near-crash situations and traffic violations. In a connected environment, important information about these critical events can be communicated to road users or the infrastructure to avoid or mitigate potential...
