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.
Documents of type: all
This digest summarizes findings of National Cooperative Highway Research Program (NCHRP) Project 3-52A, "Impacts of Access-Management Techniques." NCHRP Report 420, "Impacts of Access Management Techniques" (1999), presents relationships between access density and accident rates. This digest uses additional data from Minnesota to confirm these relationships. The digest is organized as follows: Introduction; Problem Statement; Objective and Approach; Background; Results; Comparisons; and Accident Rate Indices.
TRB's NCHRP Synthesis 348: Improving the Safety of Older Road Users examines programs and policies in place across the country to improve the safety and mobility of older road users. The report documents a range of strategies and related programs under way in roadway engineering, driver licensing, public information and education, and enforcement and adjudication.
Access Management Performance Measures for Virginia: A Practical Approach for Public Accountability
In order to develop performance measures to communicate the effect of Virginias access management program, five tasks were performed:
ICF Consulting. Congestion Management Systems: Innovative Practices, Prepared for the New York State Association of MPOs, (August 2005)
The Maricopa Association of Governments (MAG) conducted a survey of Metropolitan Planning Organizations (MPOs) to assess the implementation of access management at the regional level. The intent of the survey was to determine if access management was being implemented at the regional level; what had been implemented; and how implementation was achieved. Survey responses were divided into three categories: all respondents, respondents serving a population of one million or more (population subset), and respondents serving 25 or more member agencies (agency subset).
