Parking & Urban Form

Many studies have noted that denser and more accessible environments with higher level-of-service (LOS) tend to encourage higher levels of walking and bicycling activity. As streets are increasingly designed to facilitate safe cycling through built environment interventions, little has been done to evaluate perceptions of safety on different typologies, particularly one vs. two-way corridors. Theory would suggest that many individuals frame their commutes based in-part on the perceived safety of the environment, yet little research looks at varying street design and this perception. This study uses a moving camera approach to evaluate the perceived cycling comfort for drivers and cyclists on different roadway designs (multi-lane, one way; two-way, bidirectional street; single-lane, one-way).

Urbanism Next Center Director and Professor Nico Larco testified during the congressional hearing, "The Road Ahead for Automated Vehicles." Professor Larco highlighted the work of Urbanism Next and the potential cascading impacts of autonomous vehicles.

This report is an examination of parking, curb zones, and government service changes in the context of AVs. Given that there are very few actual AVs on the road, the analysis in this report is an attempt to project what we might see, using the current phenomenon as starting points. The report uses a mix of econometric modeling, cost accounting, and case studies to illustrate these projections.

Ride-hailing companies like Uber and Lyft are reducing the need for parking, which negatively affects parking companies but is otherwise beneficial for cities.

Various cities across England and Germany have completely abolished parking minimums.

In this book, Donald Shoup reports on the progress cities have made on the principles outlined in book The High Cost of Parking. Remove off-street parking requirements, charge the right prices for on-street parking and use that revenue towards improving public services.

In Seattle, a suburban shopping center’s parking lot is being transformed into a new walkable neighborhood.

“This research examines office parking at a series of case study sites in suburban Southern California, identifying its impact on travel behavior, development density, development cost, and urban design.”

“Donald Shoup argues that free parking has contributed to auto dependence, rapid urban sprawl, extravagant energy use, and a host of other problems.”

This is an organization that advocates to end parking minimums in cities and towns. Included is an interactive map showing progress being made to remove parking minimums.

“Parking is expensive. We can break these costs down into two categories. One is the explicit fiscal costs of parking, to the provider and to the public. The other is the implicit opportunity cost of parking, which occupies land that could have been put to another beneficial use, and/or is often built at the expense of another beneficial activity.”

Guidelines for cities to implement sustainable and environmental mobility strategies for people and goods.

This chapter estimates how minimum parking requirements increase the cost of constructing housing, office buildings, and shopping centers. It also explains proposed legislation to limit how much parking cities can require in transit-rich districts.

Although recent studies of Shared Autonomous Vehicles (SAVs) have explored the economic costs and environmental impacts of this technology, little is known about how SAVs can change urban forms, especially by reducing the demand for parking. This study estimates the potential impact of SAV system on urban parking demand under different system operation scenarios with the help of an agent-based simulation model. The simulation results indicate that we may be able to eliminate up to 90% of parking demand for clients who adopt the system, at a low market penetration rate of 2%. The results also suggest that different SAV operation strategies and client's preferences may lead to different spatial distribution of urban parking demand.

As we build new developments, are we still short on parking? Parking minimums have created endless hot, asphalt deserts in our developments and now cities are working to reverse these laws.

Seattle City Council passes in a 7 to 1 vote a plan for large parking reforms including separating parking costs from rent and increasing bike parking requirements.

The main objective of this research project is to provide FDOT with information and guidance on how best to begin to prepare for a future in which AV technology first takes root and then takes over the market. The FSU Research Team is investigating the potential impacts of widespread adoption of AV technology on the transportation network and urban form for four key land use and transportation nodes that are vital to the welfare of the State of Florida: Downtown, Office/Medical/University Center, Urban Arterial, and Transit Neighborhood. To accomplish this, the FSU Research Team engaged one-hundred planners, engineers, industry professionals, and public officials in a facilitated visioning session at the 2015 Florida Automated Vehicle Summit (FAV Summit). During this session the research team gathered input on how AVs will impact our communities and how the built environment will need to adapt to accommodate AVs in the coming decades.

"In this paper we propose a new method to study how replacing privately owned conventional vehicles with automated ones affects traffic delays and parking demand in a city. The model solves what we designate as the User Optimum Privately Owned Automated Vehicles Assignment Problem (UO-POAVAP), which dynamically assigns family trips in their automated vehicles in an urban road network from a user equilibrium perspective where, in equilibrium, households with similar trips should have similar transport costs.

The continued use of minimum parking requirements is likely to encourage automobile use at a time when metropolitan areas are actively seeking to manage congestion and increase transit use, biking, and walking. Widely discussed ways to reform parking policies may be less than effective if planners do not consider the remaining incentives to auto use created by the existing parking infrastructure. Planners should encourage the conversion of existing parking facilities to alternative uses.

This info-graph and write-up display the costs that parking spaces incur and how they are bundled into our lives.

The Global Street Design Guide is supporting practitioners to redefine the role of streets in cities around the world.

With its 1950s aesthetic intact, Knightley’s Garage is more than a kitschy throwback to the past. Wichita’s repurposed parking facility may actually be an indication of things to come. As personal auto ownership declines in urban downtowns, car-related urban infrastructure is increasingly underused. Some garages, like Knightley’s, are ripe for adaptive reuse. Others are being constructed from scratch in ways that will allow them to be repurposed down the road.

CurbFlow is a new startup that is working to map who uses the curb and when. It is using this data to create a system where delivery companies can pay to reserve a parking space.

As more people make the shift to sustainable mobility options like e-scooters, cities are evolving their transportation infrastructure to combat car dominance and to allow human-scaled modes to thrive. In addition to creating dedicated spaces for people to ride shared micro-mobility devices, this transition also includes creating space for them to park when not in use. To explore how cities should think about parking and micro-mobility, Bird sat down for a conversation with parking expert Donald Shoup.
