Car-dependent suburbs are becoming less competitive as both young adults and a growing senior population are looking to drive less. Yet the effectiveness of fixed-route transit such as rail and bus will always be limited in areas that are sparsely developed. Technology now provides an answer to this dilemma, making it possible to link bus and rail service with options ranging from biking and walking to car-sharing and van services. With proper government oversight, private on-demand car services, electric vehicles, and shared autonomous vehicles can provide better service at a lower cost. Where destinations are closer together, fixed-route bus lines may continue to be the best option. The public sector will need to manage this change with a focus on equity to make sure new technology-enabled services are affordable and accessible for all.
Suburbs were designed and built for automobile travel. When residential densities are too low and destinations too scattered, operating a comprehensive public transportation network isn’t viable. Although some corridors can support adequate bus service, residents mostly rely on cars for most, or even all, their daily trips. Traffic is choking many parts of the region; for low-income residents, needing a car to get to work can be cost-prohibitive; and for many others—including the disabled—getting around can be a real challenge.
An established commuter rail network helps anchor the region, providing many suburban residents access to New York City’s enormous and rapidly growing job base. But not all suburbs currently have good rail options, as commuter rail fares are out of reach for many moderate- and lower-income families, while access to many commuter rail stations is limited due to insufficient parking or poor local transit connections. As a result, many families—especially those with low to moderate incomes—rely on bus service for their commuting needs.
With proactive planning and innovative policies, on-demand services and autonomous technologies should drive the costs of mobility down in suburban areas while significantly improving access for lower-income riders or riders with disabilities. These services would improve safety for the elderly, women, and young people during late nights and weekends. Over time, they would also free up parking spaces for repurposing as new public spaces, affordable housing, bike lanes, or freight pickup and drop-off zones. The goal is to create an integrated mobility system that gives users multiple options for fixed-route transit or on-demand mobility.
The cost of improved service would be partially covered by the efficiency gains of on-demand transportation and eventually the labor savings through autonomous operation. However, local subsidies would likely be required to provide greater frequencies in less dense places. These subsidies could eventually be paid for through value-recapture as parking lots are redeveloped for other higher-value uses over time.
