LRT @ Phoenix


source: sreetfilms.org

Everyone knows that Phoenix has a huge sprawl problem. But now transit-oriented development is on the upswing in this Sun Belt metropolis. In December, the Phoenix region opened one of the most ambitious transit projects in recent U.S. history: a 20-mile light rail line with 28 stops serving three cities (Phoenix, Tempe, and Mesa). Future plans include an extension within three years, with several new corridors being studied.

The Valley Metro vehicles are handsome and comfortable, and thus far ridership has far exceeded initial projections -- with as many as 40,000 riders per day, compared to the expected 25,000. Each station features amenities and art installations. In addition, with many folks using the light rail as an intermodal step in their commutes, bicycles are welcome aboard.

Being handsome and comfortable is what differentiates LRT from BRT, and that's also why LRT tends to attracts way more motorists than BRT. In terms of pullution, be it dust, air quality, noise, water runoff, or vibration, LRT's performance is much better. It's possible to make the performance of BRT as close as to LRT, but the biggest advantage of BRT (cheap, cost-effective) will no longer hold. However, that LRT is around 3 times more expensive makes the option not available for a lot of countries or cities in the world.

LRT is fixed, due to its rail-based nature. Therefore, related facilities such as park-and-ride and bicycle carriage service become important to help people complete their trip (point-to-point) more smoothly. BRT is flexible and fast to go into operation, but local people also tend to think that is not as reliable and stable as LRT, which can play a critical role in people's mode choice and location choice.

Nevertheless, comparing two totally different transportation systems is not fair. From my point of view, given a rapidly growing medium-sized city, BRT would be a temporary means by which LRT will be introduced once the level of local economic development and environmental awareness raises over the tipping point.

Research (1): from Supply-side to Demand-side Approach, from Economic Incentive to Social Incentive

Today, we are standing at a point of opportunity where we can really make a difference, or we let it go by. After several decades of focusing solely on economic development and enterprise competition, we've ignored the fundamental of life - the most precious and invaluable resources - the Mother Nature. On the other hand, during just about the same period, technological progress has become unprecedentedly powerful in its nature, and also social in its ability to make each other interconnected.

One of the biggest challenges, global warming, by its nature, is such a comprehensive crisis and risk that people on this planet will need to work out a bunch of solutions collaboratively or they will suffer from the irreversible catastrophe together. However, looking at today's government policies aimed to address this issue in the post Kyoto Protocol era, cooperation has been high on the agenda, but at a level so high that people consider it the government's job. What governments around the world are good at (and they are supposed to be, since basically those are quasi-monopoly businesses), is the supply management of all sorts of public services, transportation, energy, sewer and water and so on. As a result, the progress of emission reduction has been disappointing.

The focus has yet come to the ordinary people whose collective effort once reaches the tipping point could really make a shard difference in the situation. At this micro-level, most of the green innovation and creative programs have been initiated chiefly by private sectors and NGOs.

Regarding transportation, yes, there are a variety of transportation demand management (TDM) measures such as congestion pricing, toll road, and others urging people to change travel mode by means of economic incentive. Although, if well-schemed, it will definitely show positive effect on environment and congestion, this kind of economic-incentive-based measures is not tackling the problem directly, and it's often politically implausible. In other words, people are forced to change to green mode because of economic penalty. Drivers whose mode remains unchanged are subject to the structural change

The thing that is really in need of change is the environmental and social awareness. The former explains the physical capacity of the environment and the latter represents the fact that not only welfare, but also misery of each individual is interconnected.

There comes the idea of mobility management, defined by EPOMM (European Platform on Mobility Management)

Mobility Management (MM) is a concept to promote sustainable transport and manage the demand for car use by changing travellers's attitudes and behaviour. At the core of Mobility Management are soft measures like information and communication, organising services and coordinating activities of different partners. Soft measures most often enhance the effectiveness of hard measures within urban transport (e.g., new tram lines, new roads and new bike lanes). Mobility Management measures (in comparison to hard measures) do not necessarily require large financial investments and may have a high benefit-cost ratio.

In other words, Mobility Management resorts to the real problem of the crisis. As the strategy changed from economic incentive (people don't want to get fined)to moral incentive (people don't want to do something they consider wrong), related policies also started focusing on the building of awareness, such as marketing campaigns, car-pooling, par-and-ride, and so on. Those measures are more encouraging than forcing; that is, drivers whose mode remains unchanged are not affected. Most of the measures and programs involve in some sorts of information exchange and interaction between travelers and service providers.

However, because the choice of social dilemma between public transportation and private vehicles is the fundamental source of emission of transportation sector, I argue that social collaboration is the key to the crisis. At the micro-level, one by one, inch by inch, social collaboration (therefore pro-social behavior) is to be built via the help of technology.

IBM opens Global Rail Innovation Center in Bejing



IBM opened its Global Rail Innovation Center in Beijing which is expected to bring indistry experts, academic researchers, and also officials together to improve and design the 21st century railway system. Here is what it will be doing,
The kinds of things we’ll work on are advanced data analytics for scheduling and predictive maintenance, cell phone enabled passenger service, wireless sensors on bearings and axles, digital video systems that ensure a clear track ahead and automatically respond to danger — to create rail systems that will support economic vitality, improved quality of life through reduced road congestion, and environmental sustainability.

F** This!


I ran into F** This!, a site that allows citizens to report any dissatisfaction about infrastructure in New York. The provider's job is to automatically notified related authorities to see if things will get improved. As this,
In the land of F** This! you are granted many wonderful powers. You can become a guardian of public infrastructure. You can keep your city working smoothly. You can post pictures of busted crap–partially disassembled escalators in subway stations, cavernous potholes, permanently dark street lights–and trade snide and insightful comments with your wonderful new F** This! cyberfriends (why can’t your real life friends be this cool?). At the same time, while you’re busy enjoying yourself, we’ll see to it that the appropriate public officials get notified and the problem you identified gets dealt with. Or, if said officials prove useless in fixing the busted stuff, we’ll see to it that they endure at least some small measure of public humiliation. It’ll be fun!
Using technology (mainly web and GIS) is the area I will be working on during the rest of my research.(or maybe not?)

I hope to share more things latter!
