http://www.trb.org/Main/Public/Home.aspx This website has a lot of information throughout it. If we use it we're going to have to really search through all of their documents and books for info that we can easily get through pdf's and such. I've found a few so far but I'm thinking if we look enough mayeb we can find some good overviews of alternative modes of transportation as a whole. It's got all different kinds of categories and links, but a lot of the sources are books that we can't read over the web. Throughout all of their source links, if you look long enough, there are plenty of pdf's and journal articles to skim too. I'm sure we could find something good here. http://www.trb.org/PublicTransportation/Blurbs/Rails_to_Real_Estate_Development_Patterns_Along_Th_165077.aspx For example this pdf is pretty interesting to skim through. It's about three different railways and the studies

Contrasting Visions of Urban Transport
http://www.vtpi.org/cont_vis.pdf This document isn't one that covers alternative modes of transportation in am overall sense. I just found it interesting. From what I've picked up from the intro and conclusion it seems to be mostly about keeping public modes of transportation, for example buses, public or privitizing them. It discusses which seems to be more efficient from the stand point of one article saying that privitizing would be better and

This is just going to be a short post. I found this website as I was scanning through alternate transport links for some good overall studies. It's not a study but I think the website has some good links throughout it and good information about alternative transportation. If you want to scan through some of it or look at some of the links and info it could be helpful later on or maybe even finding ways to look up good studies to use for the project.
Transportation Sector
http://www.eia.doe.gov/emeu/efficiency/ee_ch5.htm
The introduction:
Energy use in the transportation sector is primarily for passenger travel and freight movements. Passenger travel vehicles consist of light-duty vehicles (automobiles, motorcycles, and light trucks) and high-duty vehicles (buses, airplanes, boats, and trains). The freight modes of transport include truck, air, rail, pipeline, and marine (domestic barge and cargo). Energy is also used for military operations and off-highway vehicles used for construction and farming.
Petroleum supplies the vehicles in the transportation sector in the forms of gasoline, diesel fuel, liquefied
2010 International Energy Outlook: Transportation Sector Energy Consumption!
Link: http://www.eia.doe.gov/oiaf/ieo/transportation.html
Notes:
"Almost 20 percent of the world's total delivered energy is used in the transportation sector, where liquid fuels are the dominant source. Transportation alone accounts for more than 50 percent of world consumption of liquid fuels, and its share increases over the projection period...From 2007 to 2035, growth in transportation energy use accounts for 87 percent of the total increase in world liquids consumption."
Historic high oil prices - 2008
"Transportation infrastructure and driving patterns in OECD countries are generally well established. Roads and highways connect most population centers. Motorization levels (vehicles per 1,000 people), which already are high (for example, there were 765 vehicles per thousand people in the United States in 2009), are likely to reach saturation by 2035. In addition, as OECD economies have become more service-oriented, the link between income and the transportation of goods has weakened."
"In France, for example, the sales tax levied on motor gasoline accounts for 70 percent of the cost of a gallon of fuel, so that French drivers pay about 120 percent more for their fuel than do U.S. consumers."
ALT TRANSPORT!!! : "In June 2005, Mexico City's Bus Rapid Transit (BRT), Metrobus, began operating along a 12-mile length of the Avenida de los Insurgentes—often cited as the longest urban avenue in the world [4]. Today, Metrobus consists of two lines with a total length of nearly 30 miles, and there are plans to extend the system with two additional lines that will nearly double the current length of the system [5]. Metrobus is the longest operating BRT in Latin America, transporting an average of 265,000 passengers each day, and it has been credited with dramatically improving the city's air quality [6]. Its success demonstrates how important mass transit may be in shaping transportation consumption trends, particularly in fast-growing urban areas with underdeveloped transportation infrastructures."
Conclusion: Developing/emerging economies like India, China, Brazil, etc. have the most potential for alternative transportations to become primary modes, whereas USA's established infrastructure for private vehicles hinders progressive development of alternative transport.
Personal concern: Even in NYC, the recent rapid growth of bike lanes has faced much limitation and opposition from those who already own and operate private cars; also, the continued price and inconvenience increases in the MTA subway/bus system are turning many away from dependence on mass transportation.

Historic high oil prices - 2008
- Non-OECD --> continued increase in transportation energy use (subsidies in oil-rich countries)
- OECD --> decrease from 2008-2009; increase projected for mid-2010; return to 2007 levels after 2020 (slow econ recovery & fuel conservation policies
