McMahon was retained by the Massachusetts Bay Transportation Authority (MBTA) to enhance passenger accessibility, reduce travel times, and improve operations along its key bus routes, as part of a $10 million ARRA funded grant program. These routes travel along densely populated corridors throughout the Greater Boston area with high rates of transit usage, but many are plagued by service delays due to bus bunching and passenger crowding. Passenger amenities and bus access improvements were needed along these routes. McMahon’s tasks included developing a stop consolidation plan for 15 bus routes that reduced travel times, improved operations, and provided opportunities for rider amenities at proposed locations. These recommendations were made in the context of minimizing impacts to on-street parking and level of service for general traffic. We also developed plans for signal improvements, including transit signal priority and queue jump lanes, to reduce overall delays for bus service. Additional improvements, that were designed by McMahon included passenger amenities such as shelters, benches, and improved signage, curb extensions and bus access improvements. Other responsibilities included determining preliminary cost estimates and providing significant public involvement and municipal coordination.
