Issues
Bicycling
 
As the price of gasoline has risen, so has interest in more affordable transportation options.  Although biking trips account for less than one percent of all trips in America, they represent between five and 10 percent of trips taken in such cities as Eugene and Corvallis, Oregon; Palo Alto, California; and Boulder, Colorado.  In Davis, California, more than 20 percent of trips are made by bicycle.  Information on ways to make communities more bike-friendly can be found through the links below:

Connectivity
 
A balanced transportation system provides for good connections between local destinations.  Ideally, such connections include pedestrian and bicycle paths as well as streets.   Conversely, the cumulative effect of not connecting local streets between development parcels is traffic congestion on surrounding collectors and arterials.   Ideas for enhancing the "connectivity" of local communities can be found in the resources listed below.

Density and Design Issues
 
High-density development, especially when coupled with mixed land uses, is regarded as critical to the success of public transportation and walkable neighborhoods.  Such development not only provides the ridership needed to make public transportation financially viable, but it also offers a market for small local businesses located within walking distance of residential neighborhoods.  When high-density development is poorly designed, however, it often generates strong opposition.  When it is well-designed and respects the character of surrounding neighborhoods, high-density development is more likely to win community acceptance.  While high-density development is sometimes equated with offputting high rises found in big cities, it comes in quite different forms.  Some of Oregon's most popular communities -- e.g., Main Streets in Joseph, Hood River, and Ashland; downtown Baker City; and Cannon Beach -- are high-density areas.  Outside Oregon, such popular places as Carmel, Santa Barbara, and historic Santa Fe are high density.  The resources noted below discuss how communities in Oregon and around the country have addressed the design and other issues that can arise when high-density development is proposed.

Form Based Codes
 
In recent years cities have become interested in the concept of "form based codes" as a way to improve the mobility as well as the appearance of communities.  In short, form based codes emphasize building types, dimensions, parking locations and facade features over land uses.  These codes also favor mixed-use development, which brings local destinations into closer proximity to each other.  Traditional zoning codes, on the other hand, emphasize land uses over a building's physical form.  By rigidly separating land uses, zoning codes have often increased the auto dependency of communities while reducing their pedestrian friendliness.  The Model Development Code for Small Cities of the Oregon Transportation and Growth Management Program is considered a hybrid code that incorporates certain features of a form-based code.  Below are some web sites that provide more information on form based codes:

Global Warming & Transport
Oregon Strategy for Greenhouse Gas Reductions
 
Transportation is one of Oregon's largest contributors to greenhouse gas emissions.  Such emissions, in turn, fuel global warming, which is seen as a serious threat to the state's businesses and industries.  So says Governor Ted Kulongoski's Advisory Group on Global Warming in a December 2004 report, Oregon Strategy for Greenhouse Gas Reductions.  The Advisory Group notes that 84% of Oregon's greenhouse gas pollution comes from CO2 emissions and that 38% of those emissions come from transportation (mostly from cars and trucks).  Among the report's recommendations for reducing greenhouse gases in Oregon: 
  • integrate land use and transportation decisions with greenhouse gas consequences
  • incorporate greenhouse gas emission impacts into transportation planning decisions
  • expand "Transportation Choices Programs"
  • improve mass transit and inter-city transit links

Other State Strategies for Reducing Transportation-Related Greenhouse Gas Emissions
 
In early 2006, members of the New England Climate Coalition released reports on the relationships between transportation, global warming, and greenhouse gas emissions in three states:  MassachusettsConnecticut, and New Hampshire.  Recommendations offered in these reports for reducing transportation-related emissions include:  more mixed-use development, extension of transit services, and more efficient land-use patterns. 

Infill and Redevelopment
 
Many older communities offer the kinds of transportation choices that are increasingly being sought in new developments.  Historic Main Streets, downtowns, and older neighborhoods are frequently well-served by public transportation or are designed in such a way as to enable people to take many short trips by foot.  To enhance the viability of older communities while taking advantage of the transportation assets they offer, many local governments are implementing "infill" and redevelopment strategies.  The benefits of doing this -- and ways to do it -- are discussed in the resources listed below.
 
Infill and Redevelopment Handbook:  A 135-page publication, produced by the Oregon Transportation & Growth Management (TGM) Program, describing strategies for filling in, or redeveloping, underused or deteriorated sections of existing communities in a way that expands transportation options. 
 

Land Use & Transportation
 
Land use and transportation are flip sides of the same coin.  Land use decisions can either open up or foreclose transportation options, while transportation investments can (and usually do) influence land-use patterns.  Insights into, and research on, the relationships between land use and transportation are discussed in the following reports and papers:
 

Model Code & User's Guide
Many local zoning codes discourage the creation or preservation of traditional neighborhoods and Main Streets in which people have meaningful transportation choices.  Zoning-based parking, building setback, lot size and other requirements, for example, can deaden the pedestrian-friendliness of a community.  To help small communities in Oregon promote development that enables people to get around more easily, the Transportation and Growth Management (TGM) Program created a new publication in June 2005:  Model Development Code and User's Guide for Small Cities (2nd edition).  The model code integrates transportation and land use planning with a view to expanding transportation options for Oregonians.  
 

Parking
 
The creation and management of parking for motor vehicles is an important, but challenging, transportation issue.  Strategies for managing parking in ways that acommodate downtown revitalization, preservation of neighborhood livability, and adequate storage for cars are discussed in the resources listed below:

Pedestrian-Friendliness
 
Enhancing the "walkability" of a community provides many benefits.  It helps to reduce traffic congestion.  It enables people to integrate simple physical exercise -- walking -- into their daily routine.  And it avoids the worsening of environmental problems, such as air pollution, water pollution, and the emission of greenhouse gases.  For these and other reasons, many communities would like to make their residential and commercial areas more walkable.  Resources for improving the pedestrian friendliness of cities and towns are discussed in the publications noted below:

Public Health & Transportation
Recent conferences and studies have explored the relationships between urban form, transportation, and the physical fitness of Americans.  There is a growing recognition that the way communities are designed and laid out can increase -- or rule out -- opportunities to integrate such simple physical exercise as walking or biking into one's daily routine.  Articles and reports that explore this topic are noted below.

Traffic Calming
Citizens are often concerned about cars traveling too fast on residential streets.  A variety of tools -- e.g., speed humps, narrower lanes, curb extensions, etc. -- are being used by cities to "calm traffic" so that pedestrians (and especially children) can get around more safely.  Resources on this topic:  

Transport Costs of Housing
 
Transportation costs rival the home mortgage in their impact on the American household budget.  In 2003, transportation expenses accounted for 19.1% of the typical household budget.  Although housing is considered affordable if it accounts for no more than 30% of a household's monthly budget, transportation costs related to housing locations are often ignored.  A growing body of research has shown a strong relationship between mixed land uses, increased density, transit access, and pedestrian friendliness, on the one hand, and reduced automobile expenses, on the other.  With the rising cost of fuel, the transportation savings achieved by living in walkable or transit-friendly communities can be considerable.  Listed below are several resources that address this topic.
