Sustainable mobility policy for long-distance transportation services should consider emerging automobiles and aircraft as well as infrastructure and supply chain life-cycle effects in the assessment of new high-speed rail systems. Using the California corridor, future automobiles, high-speed rail and aircraft long-distance travel are evaluated, considering emerging fuel-efficient vehicles, new train designs and the possibility that the region will meet renewable electricity goals. An attributional per passenger-kilometer-traveled life-cycle inventory is first developed including vehicle, infrastructure and energy production components. A consequential life-cycle impact assessment is then established to evaluate existing infrastructure expansion against the construction of a new high-speed rail system. The results show that when using the life-cycle assessment framework, greenhouse gas footprints increase significantly and human health and environmental damage potentials may be dominated by indirect and supply chain components. The environmental payback is most sensitive to the number of automobile trips shifted to high-speed rail, and for greenhouse gases is likely to occur in 20–30 years. A high-speed rail system that is deployed with state-of-the-art trains, electricity that has met renewable goals, and in a configuration that endorses high ridership will provide significant environmental benefits over existing modes. Opportunities exist for reducing the long-distance transportation footprint by incentivizing large automobile trip shifts, meeting clean electricity goals and reducing material production effects.

The 4,280 pedestrian fatalities in 2010 were an increase of 4 percent from 2009, but
a decrease of 13 percent from 2001. In 2010, pedestrian deaths accounted for 13
percent of all traffic fatalities, and made up 3 percent of all the people injured in
"When Distracted Road Users Cross Paths" examines the relationship between distracted drives and distracted pedestrians. The authors conclude, " Ultimately, a safe roadway environment depends on all road users paying attention to where they are going and being aware of other users who might be sharing the road."
Construction is done in the library. We now have a new wall, some new paint, and new offices. We also have some new hours - we'll be open to the public Monday through Friday from 1:00 PM to 5:00 PM. Thank you for your patience.
UPDATE: The ITS Library will be closed from now until August 3rd, while we move offices and the construction in the library is finished. We will reopen with some fresh paint, another white board, and a couch on August 7th. If you want to return materials, you may do so in the drop box outside O'Brien hall or to other libraries on campus. If you need asistance or have questions, please email us at firstname.lastname@example.org
Construction is beginning today on the new wall in the library. Most of the work will be done on the weekend, so we don't anticipate any closures during the initial phase of construction, but there will probably be some noise. We'll let you know if any service disruptions occur. Thanks for your patience.
The Javelin service has been presented as a key part of the capital's transport plans since London won the right to host the games in 2005. Although the Olympic Delivery Authority insists it has "robust plans for a smooth operation", it seems that some hoping for a fast ride on the trains – which have been named after Olympians, including Tanni Grey-Thompson and Sebastian Coe – may have to travel by bus or tube.
Network Rail, which operates St Pancras station under contract to High Speed One, the station and track owners, is building queueing zones stretching into the immigration area for the Eurostar international services, in effect moving the administrative border with France to accommodate the crowds.
But Robin Gisby, director of operations for Network Rail, told the Commons transport select committee this week that the queues may be such that they will advise passengers to take alternative routes. These routes take, according to Transport for London's calculations, five or six times longer even without factoring in Olympic queues.
To help with the transport issues, Get Ahead of the Games was launched earlier this year to help keep Olympic travellers informed of the the transport sitation.
