NCDOT School Impact Calculator http://www.ncdot.org/doh/preconstruct/traffic/congestion/CM/MSTA/schools.html
NCDOT developed a school impact calculator to help new schools and their consultants determine traffic impacts and how to handle potential traffic on site. The Department also provides technical assistance to schools to ensure appropriate access and circulation design for autos, bicycles and pedestrians.

Frank Broen serves on three TRB national committees to communicate critical transportation needs that enable our multimodal transportation system provide the mobility to live in safe, productive, sustainable and attractive communities. He has worked with FDOT for over 20 years to communicate transportation planning issues, creating innovative products that help both experienced professionals and interested newcomers understand and apply transportation planning concepts.
The use of raised medians in urban areas has increased in recent years. Raised medians restrict access to businesses along a corridor by limiting turning movements to select mid-block locations. Therefore, a very common remark at public hearings related to the construction of raised medians is that there will be detrimental economic impacts on adjacent businesses. However, the restricted access allows more efficient signalization and traffic flow along the corridor, potentially providing more customers for the businesses.
The Missouri Department of Transportation (MODOT) is responsible
for one of the largest state-jurisdiction road systems in the United
States. Missouri has recently decided to embark on an access
management program and has focused on utilizing access management
mainly to meet safety, traffic operations, and economic development
goals. The Missouri Access Management program development process
involves a number of key steps. These include:
This report represents Kentuckys continued efforts to institute a state-wide access management policy, as set forth in the 2004-2008 Kentucky Transportation Cabinet (KYTC) Joint Strategic Plan. The suggestions made herein build upon the initial recommendations laid out in Access Management for Kentucky (which had also included an access management implementation plan).
This paper provides an overview of current access management programs in various states, and is one of few uncovered that focus on lessons learned during the development and implementation of the programs. Although few specific details are provided, it does include general suggestions that may be useful for the chapter on state program development. Examples of the lessons learned include hiring a large enough staff dedicated to the program, creating a separate bureau/ department/division for access management, and including a process to handle waivers.

Traffic conflict points at intersections are the points at which traffic movements intersect (including crossing, merge, and diverge). Numbers and distribution of conflict points have been used to evaluate intersection access management designs and safety performance. Traditionally, determination of numbers of conflict points for different traffic movements has been based on manual methods, which causes the difficulty for computerized procedures to evaluate safety performance of different access management designs.

The objectives of this ongoing research are to:
1. Develop evaluation models to assess the safety impact of access management policies and treatments relevant to urban, urbanizing, and suburban arterials.
2. Propose an access management evaluation framework that can be adopted by state and local agencies to evaluate compliance of access management policies, and the impacts of viable access treatment techniques.
