Access Management to Reduce Wrong-Way (WWD) Driving on Alabama Divided Highways

Beijia Zhang

A divided highway is considered as a highway with physical separation, and the side streets are its access points in this study.

WWD crashes are more possible than other kinds crashes to result in fatal or incapacitating injuries. The majority of previous studies are focused on freeways instead of divided highways.

112 WWD crashes were identified in Alabama divided highways from 2009 to 2013.

 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.

This is a one-page guide to strategies to improve safety at unsignalized intersections, including:

Imagine a multilane urban/suburban roadway where traffic is heavy, yet moves well; accommodates drivers, pedestrians, and bicyclists; allows easy entry to and exit from businesses and other destinations; and has fewer crashes and other conflicts. Chances are this road is benefitting from corridor access management, a strategy that seeks an appropriate balance between the safety and mobility of a roadway facility with the access needs of adjacent land uses.

APPLYING DESIGN FLEXIBILITY & REDUCING CONFLICTS

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.

The Intersections Joint Subcommittee has an online manual that provides state of the art guidance on unsignalized intersections.

The purpose of the Alabama Department of Transportation (ALDOT) Access Management Manual is to set out standards for managing access to and from state roads and highways.

Goals of access management include:

• protecting the health, safety and welfare of the public
• maintaining the highway rights-of-way
• preserving the functional level of state roads and highways while meeting the needs of the motoring public

Alabama Department of Transportation Access Design and Management Manual

1 Introduction

The Missouri Department of Transportation has utilized several microsimulation software packages to analyze the impacts of proposed designs, such as interchange footprint and outer road spacing. Traditionally, one of the most difficult aspects of a project has been providing a clear understanding of the final product to the public. This paper discusses the use of visual simulation models to convey access management techniques to the general public.

Sixth National Conference on Access Management, August 29-September 1, 2004, Kansas City, Missouri

This report classifies access management techniques and presents methods for estimating the safety and operational effects of the different techniques. For some techniques, quantitative assessment was not practical and case studies are presented to demonstrate good and poor practice. This report will be very useful to those developing access guidelines and policy and those analyzing specific access situations.
