Introduction and Background on Access Management 6
Section Outline Introduction Background 7
Introduction What is access management? Managing each point of access (driveways and intersections) Goal: to limit roadway conflict 8
Introduction Driver benefits related to access management: Smoother traffic flow Improved travel times Decreased delays at traffic signals Less stressful drive 9
Introduction Access Management: the coordinated planning, regulation, and design of access between roadways and land development. It encompasses a range of methods that promote the efficient and safe movement of people and goods by reducing conflicts on the roadway system and at its interface with other modes of travel These methods include improvements to benefit transit, pedestrians, and bicyclists, as well as different treatments for urban, suburban, and rural settings (Access Management Manual, 2 nd Edition, TRB 2014) 10
Introduction Key Principles of Access Management: Limit the number of conflict points for all modes Separate conflict points for all modes Provide reasonable access to each property 11
Introduction MOBILITY Arterial High Mobility Low Access Longer Trips Collector Some Access Some Mobility ACCESS Local High Access Low Mobility Shorter Trips 12
Background In its simplest form, Access Management is Conflict Management: If you reduce the rate and severity of conflicts the motorist encounters, you will reduce the crash rate, the injury rate, and improve the flow of traffic 13
Background Safety is a big component of access management Roadways are the most dangerous public facilities on the earth: About 650 people are killed each week Over 6,000 injuries each day Traffic crashes are the leading cause of death of a child, age 3 to 14 and the #1 killer of youth in the USA 14
Background The majority of crashes occur at intersections: Access related crashes at driveways and intersections represent over 55% of all traffic crashes in the US 65% to 75% in urban areas 15
Background There is no such thing as a safe access: As the number of access points per mile increase, so does the rate and frequency of total crashes NCHRP 420 16
Background Every access point is a fundamental safety problem: Allowing an access point is a decision to diminish public safety and roadway function 17
Background When access principles are applied to a specific corridor: Crashes reduced up to 50% Capacity increased 23% to 45% Travel time and delay reduced 40% to 60% 18
Background This is why access management is important and why we will discuss access management principles, design, and resources during this Conference 19

Section Outline Committee objectives Outreach subcommittee Research subcommittee Conferences subcommittee 21
Committee Objectives Access Management Committee objectives include: Increase agency and Public Awareness and Use of Access Management, nationally and internationally, including its benefits and relationship to livability and sustainability Identify unmet Access Management Research needs and promote needed research Maintain and update the Access Management Website (www.accessmanagement.info) as the primary portal for access management information and guidance, and increase its utility as an outreach tool Maintain and update the Access Management Manual and developing supporting national guidelines 22
Outreach Subcommittee Subcommittee scope: It is the mission of the Outreach subcommittee to facilitate ever-increasing awareness and implementation of access management 23
Outreach Subcommittee Subcommittee roles/responsibilities: Identify gaps in resources available to practitioners that limits the implementation of access management principles Assist in the development of tools and resources to support the implementation of access management principles Develop and maintain the accessmanagement.info website as the go-to tool in the marketing of access management 24
Outreach Subcommittee Subcommittee roles/responsibilities: Monitor and catalog the outreach activities of members and friends Drive continued outreach activities in the international community Actively support and market the national and international access management conferences Monitor and encourage liaisons with related TRB Committees and support opportunities for collaboration 25
Research Subcommittee Subcommittee scope: The access management Research Subcommittee will continually strive to advance the state-of-thepractice and state-of-knowledge related to access management through the completion and dissemination of access management planning, policy, and design research 26
Research Subcommittee Subcommittee roles/responsibilities: Peer-review access management research papers and nominate practice ready papers Coordinate sessions at the Transportation Research Board (TRB) Annual Meeting Assist in the development of Research Needs Statements (RNS) for National Cooperative Highway Research Program (NCHRP) solicitations 27
Research Subcommittee Subcommittee roles/responsibilities: Assist in the development of general research problem statements Help in the identification of gaps in access management research Share knowledge and research related to access management from local areas Act as an advocate for access management research 28
Conferences Subcommittee Subcommittee scope: The access management Conference Subcommittee will successfully coordinate, plan, organize and produce the mid-year meetings, international conferences, and national conferences Through the cooperative effort of the subcommittee members, a relevant forum to exchange ideas will be developed, as well as allowing the exploration and adaptation of techniques which will promote quality and best practices for implementation 29
Committee Involvement What can you do to be involved? Actively participate: peer-review access management research papers and nominate practice ready papers Understand the practice: read the Access Management Manual Identify research needs: help in the identification of gaps in access management research Share: share knowledge and research related to access management from your local area Champion: act as an advocate for access management in your local area 30
