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.
Access Management (Driveways)
FHWA 4 page brochure
This compliation of documents are provided to FDOT staff to help them implement access management in Florida.
Effective local access management requires planning as well as regulatory solutions. Communities should establish a policy framework that supports access management in the local comprehensive plan, prepare corridor or access management plans for specific problem areas, and encourage good site planning techniques. Land development and subdivision regulations should be amended accordingly and communities may also consider a separate access management ordinance.
The Florida Department of Transportation (FDOT) Complete Streets Handbook and new FDOT Design Manual will help us provide more context-sensitive roads by putting "the right street in the right place." This draft document is under review until July 31, 2017
FDOT Complete Streets Policy Adopted September 17, 2014
This Handbook was prepared by FDOT District 1
The Handbook is designed to generally follow the chronological order of process needed through the pre-application, application review, permit approval, and driveway construction processes.
CH2 Pre-Application Procedures
CH3 Permit Submittal Requirements
CH4 Completeness & Technical Reviews
CH5 Notice of Intent
CH6 Permit Approval and Issuance
CH7 Construction Requirements
These standards and guidelines have been developed to establish uniformity for encroachments upon roads in the South Carolina State Highway System so as to provide for the safe and efficient movement of traffic while allowing reasonable access to abutting property. This document does provide a majority of the information needed for encroachments onto the State Highway System.
Recent changes include:
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 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

This report presents a study on the influences of select cross-sectional-related design elements (specifically median configurations and bicycle
lanes) and their impact on crash severity and type, as well as the associated driver gap acceptance for turning maneuvers at midblock driveway
locations on urban arterials. The primary goal of this proposed research is to better understand how the median and bicycle lane configurations
can influence safety and operations at driveway locations.

This document became the first national guide focused specifically on driveway design since the publication of AASHTOs An Informational Guide for Preparing Private Driveway Regulations for Major Highways in 1959. Since 1959, the transportation system and its needs have changed drastically, and this report addresses the need for a comprehensive driveway design guide that accounts for vehicles, pedestrians, and bicyclists. The report identifies more than 90 design elements that directly or indirectly affect the geometric design of a driveway or access point.
