A transportation system that provides full accessibility results in a high quality system for all users. Accessible infrastructure has been linked to increased business opportunities, social development health benefits, and increased independence among community members.
Accessible design practices incorporate the needs of people with disabilities into the design and development of public infrastructure, allowing facilities to be accessed independently by people with disabilities.
The Americans with Disabilities Act requires pedestrian infrastructure be accessible and usable by people of all abilities. Some elements of an accessible pedestrian route include:
ADA requirements are integrated into all Oregon Department of Transportation standard drawings, details, specifications and design manuals. In addition, ODOT prepares guidance and element designs to maximize accessibility in new construction and existing facilities. Technical guidance documents clarify when, where, and how to provide access in the many unique situations found along the state highway system.
For each project element, technical requirements are provided to guide the design of accessible public facilities. Project requirements for ADA can be found in the ADA Curb Ramp Process document.
When curb ramps are included in a project, ODOT requires several processes to ensure the constructed curb ramp will comply with accessibility requirements. The processes are summarized in the ODOT ADA Curb Ramp Process document.
The ADA requires that curb ramps be addressed when street pavement is altered with resurfacing. Curb ramps must be placed where they are needed or replaced if they are not compliant.
The following documents explain overarching project requirements, clarify ADA obligations for paving or resurfacing projects, and detail requirements for ongoing maintenance.
An accessibility evaluation of bridge sidewalks is required when:
Required ADA upgrades may be triggered by bridge rehabilitation and maintenance projects. See BDM Chapter 1, Section 16 for additional information.
The following documents explain requirements related to bridge sidewalk and curb ramp elements.
Per Oregon statute, every intersection is a pedestrian crossing unless the crossing is closed by official action.
The location of pedestrian signal equipment should be determined in conjunction with the curb ramp and crosswalk layout.
You must evaluate the pedestrian push buttons for accessibility triggers as well as the surrounding area for reach, range and landing requirements, when a project includes any of the following elements:
Accessible pushbuttons are required when traffic signal work is considered to be an alteration.
Technical guidance documents TR16-01(B) and TR16-02(B) have been incorporated into the Signal Design Manual. These documents discussed requirements for pedestrian signal equipment and audible pedestrian signals.
The following document explains maintenance work requirements.
Accessible parking spaces must be addressed when a project alters a parking lot or on-street parking that is metered or marked.
If sidewalks and pavement are altered, the parking access aisle must also be addressed.
A Temporary Pedestrian Accessible Route is a required component of every Traffic Control Plan.
The TPAR details how pedestrians will be directed through or around a work zone. The level of detail required for the TPAR depends on the complexity of the project and the volume of pedestrian traffic.
ODOT ensures that ADA processes are followed on federal-aid local projects, including for those certified local public agencies that do not have ADA certification from FHWA and ODOT.
ODOT maintains an inventory of curb ramps on state highways. The inventory data is collected from on-site visual inspections conducted statewide by certified inspectors.
ODOT provides training for ADA curb ramp inspectors. The training presentation provides information on the equipment, measurements and procedures required to conduct inspections.
