Mobility Perspectives

Four Ways Shared Autonomous Vehicles Will Reshape Our Cities

Ashley Z. Hand | July 11, 2017

Transportation technology is evolving at an exponential rate and, for the first time since the advent of the automobile itself, we have a unique opportunity to completely rethink our cities as they are shaped by transportation networks. With the advent of autonomous vehicle (AV) technologies, and the proliferation of shared mobility, there has never been a moment as critical as now to envision the city of the future.

With more than two-thirds of American adults having access to smartphones and the ubiquitous connectivity of Wi-Fi and broadband services, new transportation service delivery models and mobility marketplaces have emerged, challenging the status quo while offering new alternatives to consumers.

Shared mobility — which enables users to gain short-term access to transportation modes as-needed — has introduced new transportation choices into the market. Transportation network companies such as Uber and Lyft are merely two of the many such platforms that challenge the status quo while services like carshare, bikeshare and scooter sharing are being introduced in market.

AVs have the potential to transform mobility in cities by providing new populations previously unable to drive themselves with access to vehicles; eliminating human error in traffic crashes; and creating more efficiency through connected vehicle and infrastructure technology. It is estimated that AVs will reduce crashes by 90 percent and save the United States economy $190 billion annually1.

This potential goes beyond just the vehicles and the services: this is a chance to rethink the public realm and strike a new balance between people and city.

Here is how the advent of this broad mobility shift presents four major opportunities to redesign how our cities are developed and citizens move.

1. We can create better quality streets designed to move people, not just vehicles

Since the advent of the automobile, urban streets have traditionally been designed to move as many vehicles as efficiently as possible through and around our cities and measured by Level of Service (LOS). In Los Angeles, more than 15 percent of the total land is dedicated to streets — the largest road network in the United States — and most effectively supports the single occupancy vehicle. With a growing population, it is becoming more important to design streets to accommodate other mode choices — whether active transportation (walking and biking), shared mobility or public transit.

With recent efforts to address public safety and eliminate crashes, cities are rethinking the design of these roadways and are acknowledging through public policy, design guidelines and smart traffic management solutions that there is a need for greater balance in our public right-of-way. As a result, cities are adopting protected bike infrastructure, bus priority lanes, street trees, safer pedestrian intersections and other roadway design strategies to reshape how our city streets are used. Studies show that more walkable neighborhoods are more desirable to consumers and increasingly consumers are choosing walkability and access to services over front lawns when deciding where to live2.

2. We can rethink our streetscape and design for better access for all

Many buildings and developments have increasingly turned their back on the public right-of-way to face and serve tenants and visitors who are entering from a parking garage or parking lot. Large setbacks behind surface lots make these developments unapproachable and even unsafe for pedestrians and transit riders accessing main entrances on foot from the street by requiring them to cross large spans of parking. Even in areas with little to no setback, commercial properties have often closed building entrances facing the sidewalk in favor of controlled access from a more parking-centric entrance.

Cities must require through zoning and/or other design guidelines that our buildings and streetscapes serve to activate the public realm with people, including the growing population of shared mobility users who are being dropped off. Developers must prioritize and designers must advocate for buildings that serve active transportation access and other alternatives to the single occupancy vehicle, especially when considering an autonomous future.

3. We can eliminate parking lots for better uses

Here are three troubling statistics for consideration: the County of Los Angeles has an estimated 200 square miles of parking3 there are roughly six parking spots per vehicle in the United States; and the average vehicle is parked approximately 95 percent of the time4. Through a combination of AV, car sharing and right-sizing car ownership, it is estimated that up to 85 percent of automobiles in cities can be eliminated with a significant impact on congestion and creating a sea change for the auto industry5.

By creating a culture of shared mobility today and working efficiently to adapt our digital and physical infrastructure to support AV in the future, cities can redefine the use of its public right-of-way and alleviate pressures on the built environment that currently support single occupancy vehicles and their onerous parking requirements. We can reclaim this land given to the automobile for public open space, public safety, programming and higher density development.

Rules for parking are generally based on building use and square footage with little consideration for location or proximity to public transit. This approach is outdated and fails to address additional variables that impact personal choices and behavior. Cities must also rethink the entitlement process, and train its staff in urban design best practices that focus on people, not storing cars.

While some have advocated for the complete cessation on the construction of any new parking in the United States, a phased approach to implementing these changes could start with commercial developers who voluntarily accommodate multiple modes in exchange for reduced parking requirements or identifying overlays in transit-rich parts of the city. If located near existing transportation hubs, developers should be encouraged to create a travel demand management program to understand impacts and define a comprehensive approach to balancing all of the different ways people may access their building — whether on foot, bicycle, bus or shared vehicle.

Reforming parking policies to enable more shared use of parking is another interim consideration. Decoupling parking from the sale or lease of housing units would give property owners more flexibility to sublease or share parking with other users during non peak periods. In San Francisco, California, a building developer offered potential tenants $100 in ride-hailing service credits to incentivize going car-free, thus eliminating the parking demand on the property. Creating more flexibility in the market can help incentivize alternative methodologies to supporting transportation to and from a building without being limited to just supporting the single occupancy vehicle.

As new technologies emerge and transportation behaviors change, cities need the flexibility to support new modes and access options. Developers should advocate for the elimination of parking requirements and push financial institutions to create new financing formulas to free up finance for projects seeking alternatives to constructing new parking. Cities should adopt codes that allow for parking structures to be constructed with more flexibility to be adapted for other uses as mobility services continue to evolve. In Denver, developers are already testing these alternatives in anticipation of the future of urban mobility6.

4. We can optimize the accessibility of our communities through better land use

Affordable transit-oriented development can improve communities by making it easier for people to choose transportation options near where they live and work. First and foremost, development should strive to reduce the burden of transportation on household budgets — the second highest monthly expense.

Transportation and land use are inseparable and current methods for evaluating transportation services do not account for the productivity of land use or overall market productivity — rather they rely on delay-based metrics. Integrating these considerations can help cities deliver better planning and services.

Furthermore, today’s technologies help meet people’s demand in real-time, reducing the impact of mobility on our environment and society through greater efficiency. Urban design can amplify benefits and increase options for people. Density and diversity of such development should strive to connect with mobility options. Cities must embrace the potential of this evolving marketplace while maintaining focus on providing equitable access to safe services.

Shared mobility can also encourage greater use of transit by providing much-needed connections for the first-last mile of trips. It is important, however, to consider these services as part of a system or marketplace of solutions. Riders are going to choose the mode that best meets their needs and priorities whether it is schedule, proximity to service, cost of the trip, environmental impact or even health benefits. Providing flexibility to choose the right mode requires supportive public policy and collaboration.

AV and shared mobility are introducing exciting possibilities for cities and can revolutionize how we use the public realm. As cities grow, however, more of the same dependency on the single occupancy vehicle will bring traffic to a standstill. The public and private sector must work together today to shape a future of urban mobility that contributes to goals for livability, sustainability and access to economic opportunity.
