Unfortunately the system in most cities in India is broken, and most notably so in Chennai. The government-mandated meter is never switched on, and the passenger has to negotiate the fare upfront before boarding. Residents of the city consider the system to be highly overpriced, and a significant section doesn’t even venture to travel by it. In Bangalore and Mumbai, rickshaws refuse to ply to areas from where they are unlikely to get onward passengers, and in a number of cities, it is rumoured that the number of autos on the road far exceeds the number of licenses issued.Reforming any form of dispersed and piecemeal transportation utilities is a gargantuan task in India.

The source of the disconnect between San Francisco's transit-first heart and its car-centric hand is an arcane engineering measure called "level of service," or LOS. In brief, LOS suggests that whenever the city wants to change some element of a street — say by adding a bike lane or even just painting a crosswalk — it should calculate the effect that change will have on car traffic. If the change produces too much congestion, then a great deal of time, money, and additional analysis must go toward the project's consideration.

IN the future, perhaps our time will be known as the first decade of the Bicycle Wars, with righteous armies fighting over traffic lanes, bike paths and sidewalks, indeed over the very purpose of the streets themselves. Like many wars, it’s a question of territory, and the pedestrian has been losing for years.

The World's Most Failsafe Wireless Bicycle Brake Could Seed a Variety of Super-Safe Technologies
october 2011 by patrix
Saarland University's Holger Hermanns and the Wireless Bike Brake Saarland University
As the world goes increasingly wireless, we've learned to tolerate a certain degree of failure in our wireless systems--like when your computer just won't sync up with the wireless internet at the cafe, or when our phones drop a call. But what about situations when wireless systems simply cannot fail? A failure rate of zero is tough to achieve in any system, but computer scientists at Saarland University in Germany have demonstrated a wireless bicycle brake that works 99.999999999997 percent of the time.
That means in a trillion braking attempts, it fails three times on average. It's not perfect, mathematically speaking, but for practical purposes it's pretty close.
The brake isn't the usual handlebar brake lever customary on most bikes, and because it is wireless it naturally dispenses with the usual brake cable snaking down the frame of the bicycle to the front or rear wheel. To brake with the wireless system, the rider simply squeezes the rubber grip on the handlebar, which is fitted with pressure sensors. The harder the rider grips, the more pressure is applied to the front wheel brake. The signal sender is about the size of a cigarette pack and fixed to the handlebar. The receiver sits at the end of the bicycles fork and turns wireless radio signals from the grip into mechanical pressure on the front wheel.
That all sounds simple enough for a wireless bicycle brake, but the idea is to create a testbed for wireless technologies that absolutely cannot fail, like those envisioned for future train systems or for commercial jetliners. Starting with a simple handbrake, the Saarland team hopes to build the complex technologies necessary to ensure safety in wireless systems.
After all, brake failure on a bicycle is dangerous. But brake failure on a train could be catastrophic. Three failures in a trillion is a pretty good mark to start improving upon.

june 2011 by patrix
Overall we find that bicycling infrastructure creates the most jobs for a given level of spending: For each $1 million, the cycling projects in this study create a total of 11.4 jobs within the state where the project is located. Pedestrian-only projects create an average of about 10 jobs per $1 million and multi-use trails create nearly as many, at 9.6 jobs per $1 million. Infrastructure that combines road construction with pedestrian and bicycle facilities creates slightly fewer jobs for the same amount of spending, and road-only projects create the least, with a total of 7.8 jobs per $1 million.

“The study shows a 20 percent overall reduction in travel time compared to similar intersections that use conventional traffic designs,” says Dr. Joe Hummer, professor of civil, construction and environmental engineering at NC State and one of the researchers who conducted the study. “We also found that superstreet intersections experience an average of 46 percent fewer reported automobile collisions – and 63 percent fewer collisions that result in personal injury.”

Why Misleading Mobility Measures Are Making Things Worse

october 2010 by patrix
A close examination shows that the UMR has a number of major flaws that misstate and exaggerate the effects of congestion, particularly the Travel Time Index (TTI). TTI is the ratio of average peak hour travel times to average free flow travel times. Furthermore, for the 51 metropolitan areas analyzed in Driven Apart, the UMR overstates the cost of congestion by about $49 billion. Because this methodology does not take into account travel distances, it universally rewards cities that are spread out as opposed to compact urban areas.

Residents Who Live Near Public Transportation Live Healthier, Longer Lives
august 2010 by patrix
"A new report, released by the American Public Transportation Association, which surveys current research has found that people who live in communities with high-quality public transportation drive less, exercise more, live longer, and are generally healthier than residents of communities that lack quality public transit."
One of those studies with a 'duh' conclusion. But in this age of skepticism, every such study helps. As the study concludes, "this analysis can help transport and health professionals better coordinate their efforts to create communities where people can live long and prosper…. When all impacts are considered, improving public transit can be one of the most cost effective ways to achieve public health objectives."

“Straddling” bus–a cheaper, greener and faster public transit
august 2010 by patrix
"Proposed by Shenzhen Hashi Future Parking Equipment Co., Ltd, the model looks like a subway or light-rail train bestriding the road. It is 4-4.5 m high with two levels: passengers board on the upper level while other vehicles lower than 2 m can go through under. Powered by electricity and solar energy, the bus can speed up to 60 km/h carrying 1200-1400 passengers at a time without blocking other vehicles’ way."
Definitely an idea worth exploring to reduce congestion. Just don't call it socialized transportation please.

"Skibsted and his partners in the KIBISI design studio have taken a less grounded look at the future of urban mobility when they were asked by Woburn, Massachusetts-based Terrafugia to redesign their flying car. The result, Terrafugia's next-generation Transition Roadable Aircraft, was unveiled on Monday. The Federal Aviation Administration is on board, having granted an addition 110 pounds within the Light Sport Aircraft category so that the Transition can integrate typical safety features found in cars."

Several of these arguments are based on assumptions that guided the U.S. response to the Sept. 11, 2001, attacks -- and unfortunately, they are as unfounded now as they were then. The biggest whopper of all? The paternalistic assertion that the government can keep us all safe without our help.
