NEW! NCHRP Research Report 875: Guidance for Evaluating the Safety Impacts of Intersection Sight Distance is a resource for practitioners involved in the planning, design, operations, and traffic safety management of stop-controlled intersections. It provides information on how to estimate the effect of intersection sight distance (ISD) on crash frequency at intersections and describes data collection methods and analysis steps for making safety informed decisions about ISD.
TRB's newest publications on access management draw on national and state research to respond to the need for a more coordinated approach to transportation and community design that preserves the safe and efficient movement of peoples and goods, provides supporting networks in developed areas, and reinforces desired urban form.
TRB sponsored the 5th International Conference on Roundabouts which took place on May 8-10, 2017, in Green Bay, Wisconsin. The conference focused on research, design, operation, safety, evaluation, and practical experience with the increasingly used roundabout form of an intersection. Visit the proceedings website to view the presentations, final program.
TRB's Access Management Application Guidelines (AMAG) focuses on the applications of access management concepts and provides research-based guidelines on access management treatments and procedures for their applications. The AMAG is a how-to tool for continuing the evolution of access management applications in the United States.

APPLYING DESIGN FLEXIBILITY & REDUCING CONFLICTS
FHWA-HEP-16-055 Aug 2016
This resource provides practical real-world planning and design information to help communities achieve connected pedestrian and bicycle networks. These networks help people of all ages and abilities get where they need to go, including to and from jobs, school, grocery stores, health care, recreation, and transit. Complete multimodal networks enhance access to opportunity for everyone and help reconnect communities.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 488: Roundabout Practices summarizes roundabout policies, guidance, and practices within state departments of transportation (DOTs) as of 2015. The synthesis may be used as a reference for state agencies that are creating or updating their roundabout and intersection control policies.

Operational Effects of Geometrics and Access Management, 2015
TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2486, explores 10 papers related to operational effects of geometrics and access management in the transportation sector, including:
TRB’s Access Management Manual, second edition, provides guidance on a coordinated approach to transportation and community design that is designed to help enhance mobility, provide greater mode choice, and improve environmental quality. The content is interdisciplinary, with guidance pertinent to various levels of government as well as to pedestrians, bicyclists, and motorized vehicles, including trucks and buses. Access management is addressed comprehensively, as a critical part of network and land use planning. Key updates include
Experimental Analysis of a Direct Access Driveway at a Roundabout: Performance with one or more slip lanes

Roundabouts and Access Management
Classification and Design of Highway At-Grade Intersections
TRBs National Cooperative Highway Research Program (NCHRP) Report 650: Median Intersection Design for Rural High-Speed Divided Highways explores common safety issues at median intersections on rural divided highways, and examines innovative geometric and operational treatments for addressing those issues. The report includes ten case studies that illustrate how various treatments have been applied in the field.
