Urban Growth and Decline: The Role of Population Density at the City Core
December 21, 2011|Economic Commentary, Federal Reserve Bank of Cleveland
More Resources:
In recent decades, some cities have seen their urban centers lose population density, as residents spread farther out to suburbs and exurbs. Others have kept populous downtowns even as their environs have grown. Population density in general has economic advantages, so one might wonder whether a loss of density, which may be a symptom of negative economic shocks, could amplify those shocks. This paper looks at four decades of census data and show that growing cities have maintained dense urban centers, while shrinking cities have not. There are reasons to think that loss of population density at the core of the city could be particularly damaging to productivity. If this is the case, there could be productivity gains from policies aimed at reversing that trend.
Mobility Planning and Barrier-Free Access for People with Disabilities in Dresden
November 29, 2011|City Planing Office Dresden
More Resources:
The topic of barrier-free access is of great importance in Dresden. Dresden has a population of over 508,000 inhabitants, more than 60,000 of whom have a disability. Demographic changes and an increase in the number of older people mean the number of people with disabilities continues to increase.
10 Strategies For Attracting Investment Near Transit

Background
Over the next 25 years, the San Francisco Bay Area is projected to grow by an estimated 22 percent—adding around 1.6 million new residents. Land use and development professionals are engaged in a dialogue around how the region can accommodate this growth in a way that maintains the extraordinary quality-of-life that attracts people to live and work in the region. With an eye toward demographic shifts like an aging population and an increasing number of smaller and non-family households, planners and developers recognize the growing demand for homes and jobs in walkable, urban environments.
High land and housing costs in the core areas of the region, however, create continued development pressure in the outskirts of the region, leading to commute-times and household transportation costs that are among the highest in the nation. The high cost of housing and transportation is particularly felt by the region’s moderate- and lower-income families, who in some cities spend as…
Model Design Manual for Living Streets
October 11, 2011|Los Angeles County

Context
A growing number of communities are discovering the value of their streets as important public spaces for many aspects of daily life. People want streets that are safe to cross or walk along, offer places to meet people, link healthy neighborhoods, and have a vibrant mix of retail. More people are enjoying the value of farmers’ markets, street festivals, and gathering places. And more people want to be able to walk and ride bicycles in their neighborhoods.
People from a wide variety of backgrounds are forming partnerships with schools, health agencies, neighborhood associations, environmental organizations, and other groups in asking their city councils to create streets and neighborhoods that fit this vision.
As a result, an increasing number of cities are looking to modify the way they design their streets. They are often stifled by standards and guidelines that prevent them from making the changes they seek. Some want to modify their standards and manuals, but don’t…
The Impact of Carsharing on Household Vehicle Ownership
July 8, 2011
More Resources:
Carsharing in North America is changing the transportation landscape of metropolitan regions across the continent. Carsharing systems give members access to an automobile for short-term use. The shared cars are distributed across a network of locations within a metropolitan area. Members can access the vehicles at any time with a reservation and are charged by time or by mile. Carsharing thus provides some of the benefits of personal automobility without the costs of owning a private vehicle.
Land Use Impacts on Transport

More Resources:
This paper examines how various land use factors such as density, regional accessibility, mix and roadway connectivity affect travel behavior, including per capita vehicle travel, mode split and nonmotorized travel. This information is useful for evaluating the ability of land use policies such as Smart Growth, New Urbanism and Access Management to help achieve transport planning

An Assessment of Urban Form and Pedestrian and Transit Improvements as an Integrated GHG Reduction Strategy
April 1, 2011|Washington Department of Transportation
More Resources:
This study is one of the first to test the effect of sidewalks on travel patterns and the first we know of to relate sidewalk availability with VMT (Vehicle Miles Traveled) and GHG (Greenhouse Gas) emissions. Recently, several large jurisdictions in King County have developed local sidewalk data layers, creating a new opportunity to look at pedestrian infrastructure alongside other investment and policy strategies associated with reduced VMT and CO2 (carbon dioxide). The study used travel outcome data from the 2006 PSRC (Puget Sound Regional Council) Household Activity Survey. The household-level analysis was restricted to households in King County cities where sidewalk data was already available, and modeled the association of urban form, pedestrian infrastructure, transit service and travel costs on VMT and CO2, while controlling for household characteristics known to influence travel.
The results provide early evidence in the potential effectiveness of …

This Recommended Practice introduces guidelines for designing and operating sustainable transit that both reduces a community’s environmental footprint from transportation and enhances its quality of life by making travel more enjoyable, affordable and timely.
Frameworks of Sustainable Transit Communities
February 1, 2011|Office of the Mayor, City of Los Angeles
More Resources:
This report describes the key principles for creating successful STCs. These principles will be incorporated into future planning efforts. Many of these principles can be implemented by the City through public improvements. Others will require cooperation from private developers as they construct new buildings and rehabilitate Los Angeles’ existing stock of buildings. In some cases, public/private partnerships may be the most effective way to translate these principles into successful, thriving STCs.
No More Freeways: Urban Land Use Transportation Dynamics Without Freeway Capacity Expansion
January 1, 2011|Oregon Transportation Research and Education Consortium
More Resources:
Observations of the various limitations of freeway capacity expansion have led to a provocative planning and policy question – What if we completely stop building additional freeway capacity. From a theoretical perspective, as a freeway transportation network matures, there exists a saturation point beyond which any additional freeway capacity would only be counterproductive from a welfare point of view, and worsen the existing urban transportation problems. Traditional benefit/cost analysis of individual freeway capacity expansion projects often ignores long-term induced demand and land use changes and does not represent a systems approach to this important theoretical issue. From a practical perspective, a no-more-freeway policy can relieve transportation funds for other potentially more effective usages, such as improving urban arterial street system, improving transit level of service and coverage, implementing demand management and pricing strategies, and facilitating more…
