Abstract:This study explored the feasibility of using movable and reusable boarding and alighting (B&A) pads at bus stops. ; Potential design alternatives in terms of materials and structural support for these pads were evaluated. The review ; focused on the existing and alternative design materials, especially in applications other than for transit purposes, ; which could potentially replace the existing conventional cast-in-place concrete slab. ; An online national survey of bus transit agencies was conducted to determine how transit agencies are meeting the ; Americans with Disabilities Act (ADA) bus stop accessibility requirements and to get feedback and related ; information on the potential use of movable B&A pads at bus stops. A total of 84 transit agencies from 31 states and ; Puerto Rico responded to the survey. From the responses, none of the transit agencies were found to be using ; movable B&A pads. The potential benefits for using movable B&A pads were identified to be lower installation and ; maintenance cost, ease of installation and use, quicker installation, flexibility, portability, and passenger ; accessibility. Some potential concerns included lower durability, strength, and stability; greater risk of theft; space ; limitations; safety; and aesthetics. ; Six materials (i.e., concrete/asphalt, metal, rubber, thermoplastic, composite, and wood), along with their ; commercially available products, were evaluated based on their structural performance, long-term durability, ; adaptability, life cycle cost, aesthetics, and safety and accessibility of transit riders with mobility devices. Out of the ; six materials, plastic lumber and metal were found to have the highest potential to replace the conventional design. ; The plastic lumber presents the most viable option but the metallic materials, even though more expensive, have ; more potential for quicker installation, which can benefit transit agencies with anticipated frequent route changes. ; Additionally, the designs of each material option were proposed and recommended for further investigation.
