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.

FHWA/Safety/Intersection/Intersection Safety

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.

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

up
Click here if you liked this information

The Missouri Department of Transportation (MoDOT) is conducting a group of studies to determine how to improve 200 miles of Interstate 70 between St. Louis and Kansas City. Addressing access within the functional boundary of interchanges is a key element of the project. The paper first briefly reviews I-70 decision making studies and MoDOT's access management guidelines. Attention is then focused on access management and the National Environmental Policy Act (NEPA).

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.
