According to Reuters, Kystverket, the Norwegian Coastal Administration has approved plans for the world's first shipping tunnel. Likely to cost around $310 million, the tunnel would span 1,700 metres (5,577 feet) across the base of the Stad peninsula. The tunnel is to be located well inland where the openings would be sheltered from the raging storms of the North Sea.
Last year, according to Heather Robinson, a U.P.S. spokeswoman, the software helped the company shave 28.5 million miles off its delivery routes, which has resulted in savings of roughly three million gallons of gas and has reduced CO2 emissions by 31,000 metric tons. So what can Brown do for you? We can’t speak to how good or bad they are in the parcel-delivery world, but they won’t be clogging up the left-hand lane while they do their business.
SF City Planner, Billy Charleton, is interviewed on KQED Radio as he describes using SF Champ 3.0, an unusually sophisicated traffic modelling program which contains census data on 750,000 SF residents. In each scenario he runs, the simulation shows that traffic congestion is reduced with the introduction of congestion pricing. Critics of congestion pricing, however, point to London which charges about $16 to enter downtown during business hours. There, retail sales have declined since congestion pricing started.
- Take a cab or limo to the airport -- At the cost to park of $20 a day, if you are going more than four days, its probably cheaper to take a cab, both ways.
- Have a friend drop them off or pick them up.
- Reserve a space on line -- virtually all airports are represented at a number of sites -- Key in "Parking" on Google and see what pops up.
- Simply drive to the airport and park in an available space. My spies tell me that at virtually all airports there is parking available. It may not be the most convenient, but its there. Off airport parking is available, too. But its probably important to plan ahead and be sure you can find those little lots around the corner and down the block.
- Airport hotels are offering park/sleep/fly packages that let you come a day early, leave your car, stay overnight, and be well rested for your flight.
Of course most won't take this advice, and most main stream media won't print it. All those "one flight a decade" folks will jam the airport at the last minute, have far too much luggage, complain about just about everything, and actually be the cause of most late flights.
Cynic? Nope, just experienced.
The best solution - have Thanksgiving at your house and let the family come there.
The Toronto Star reports police in that city last monday kicked off their week-long "Smart Ped - Be Bright At Night" program in order to boost pedestrian and automobile safety. Similar safety campaigns held every November in Toronto are scheduled to coincide with the end of daylight savings time when police report a significant rise in the number of pedestrian/automobile collisions. Sgt. Allan Finlay explains that pedestrians and drivers haven't adjusted to the dark commute home.
To believe [risk compensation concerning safety restraints in automobiles] you'd have to believe that people have a certain tolerance for risk and that their levels of risk are regulated by a homeostatic mechanism so that, if forced to "consume" more safety than they voluntarily would choose, people will balance the safety increase by taking more risk. It's a stretch, isn't it? (p 6)
"the evidence with respect to seat belts suggests that the law had no effect on total fatalities but was associated with a redistribution of danger from car occupants to pedestrians and cyclists. (p 89)
Various theories have been proposed to describe vehicular traffic movement in cities on an aggregate level. They fall short to create a macroscopic model with variable inputs and outputs that could describe a rush hour dynamically. My dissertation work shows that a Macroscopic Fundamental Diagram (MFD) relating production (the product of average flow and network length) and accumulation (the product of average density and network length) exists for neighborhoods of cities in the order of 5-10km2. It also demonstrates that conditional on accumulation large networks behave predictably and independently of their Origin-Destination tables. These results are based on analysis using simulation of large scale city networks and real data from urban metropolitan areas. The real experiment uses a combination of fixed detectors and floating vehicle probes as sensors. The analysis also reveals a fixed relation between the space-mean flows on the whole network and the trip completion rates, which dynamically measure accessibility. This work also demonstrates that the dynamics of the rush hour can be predicted quite accurately without the knowledge of disaggregated data. This MFD is applied to develop perimeter control strategies based on neighborhood accumulation and speeds and improve accessibility without the uncertainty inherent in today’s forecast-based approaches. The looking-for-parking phenomenon that extends the average trip length is also integrated in the dynamics of the rush hour
A System-Wide Adaptive Ramp Metering (SWARM) system is being implemented in the Portland metropolitan area, replacing the previous pre-timed ramp-metering system. SWARM has been deployed on six major corridors and operates during the morning and afternoon peak hours. This study entails a “before” and “after” evaluation of the benefit of the new SWARM system as compared to the pre-timed system using the existing data, surveillance and communications infrastructure. In particular, the objective of this study is to quantify the system-wide benefits in terms of savings in delay, emissions and fuel consumption, and safety improvements on and off the freeway due to the implementation of the SWARM system. A pilot study was conducted for two weeks on a 7-mile freeway corridor in an attempt to develop a strategic design for the future regional-level study. This paper discusses the selection process of the study corridor, experimental design, and the results that were obtained from the pilot study.
Northwestern University's Library has announced today the launch of a Web site of 381 airline menus from the 1950s to the present, at http://digital.library.northwestern.edu/tranmenus, reproduced in their entirety in high resolution. The "Clug Calypso" menu pictured at right is from a 1968 Air Canada flight to the Bahamas.
In 1966, a passenger flying BOAC economy class from London to Tel Aviv enjoyed a lunch of foie gras, fresh Scotch salmon, salad, cheese, fruit and coffee, followed by afternoon tea. And one had only to ask for a complimentary Martini -- sweet or dry -- and free in-flight cigarettes in plain or filter tip.
TWA travelers flying first class from London to Chicago that year chose their cocktails, whiskies, highballs or champagne from a menu in the form of a scroll that doubled as a souvenir. Their dinner of curried squab chicken or Maine lobster Newburg began with fresh Malossol caviar, and was capped off with assorted French cheeses, pastries or ice creams. Diners with less rarified tastes could substitute a hot dog and malted milk.
Rising demand for parking at suburban transit stations, such as the Bay Area Rapid Transit (BART) District in California, necessitates strategies to manage traveler demand. To better manage parking supply, researchers implemented a smart parking field test at the Rockridge BART station from 2004 to 2006 to evaluate the effects of smart parking technologies (changeable message signs (CMSs), Internet reservations and billing, mobile phone and personal digital assistant communications, and a wireless parking lot counting system) on transit ridership and response to service pricing. Researchers employed expert interviews, Internet surveys, focus groups, and parking reservation data to conduct this analysis. This presentation provides an overview of the project, behavioral effects of the field test, and lessons learned.
After moving out of an old townhouse in Boston when her first child was born in 2000, Reyes started looking into the effects of lead poisoning. She learned that even low levels of lead can cause brain damage that makes children less intelligent and, in some cases, more impulsive and aggressive. She also discovered that the main source of lead in the air and water had not been paint but rather leaded gasoline — until it was phased out in the 1970s and ’80s by the Clean Air Act, which took blood levels of lead for all Americans down to a fraction of what they had been. “Putting the two together,” she says, “it seemed that this big change in people’s exposure to lead might have led to some big changes in behavior.
At Chicago O'Hare International Airport, screeners missed about 60% of hidden bomb materials that were packed in everyday carry-ons — including toiletry kits, briefcases and CD players. San Francisco International Airport screeners, who work for a private company instead of the TSA, missed about 20% of the bombs, the report shows. The TSA ran about 70 tests at Los Angeles, 75 at Chicago and 145 at San Francisco.
This seminar is to discuss the representability of discrete logit-type models including multinomial logit and nested logit model from a mathematical approach instead of a statistical approach by Prof. D. McFadden. It is shown that the logit-type models can be reconstructed from mathematical approximation theory with sigmoidal functions widely used in Neural Network modeling without the basic assumptions such as IIA and iid, and the distribution (or density) function of the unobserved portion of utility. This explains mathematically why logit-type models can approximate the choice probability function to some accuracy. It is hoped that this may suggest the way to improve the accuracy in model specification for logit type models.
Earlier this year, Boeing warned that a worldwide shortage of fasteners that hold the plane’s fuselage, wing and tail sections together was slowing down assembly of the first test aircraft. Last month, the company said that in addition to the fastener shortage, Boeing and its production partners had run into unanticipated snags involving the availability of certain specialized parts for the plane as well as the programming of its flight-control software. Mike Bair, general manager of the 787 program, conceded at the time that these problems had added “increased risk” that there would be delivery delays.
The lanes are billed as the salvation of the suffering commuter. Solo drivers will be able to buy their way around congestion, while carpoolers will ride free. But the lanes' success hinges on finding a way to differentiate between paying and nonpaying customers without stopping every vehicle to count heads.The system automagically detects the number of passengers in passing vehicles by bouncing infrared waves off of their skin. This marks a departure from computer vision-based approaches for detection in similar circumstances (for example, automated pedestrian detection).
Tired of driving the same old way? Want a new form of mobility that bridges the gap between an automobile and public transportation? Can you envision yourself in a cybercar? See what the Europeans are doing ... and will it ever catch on in the U.S.?
The Cell Transmission Model of a freeway with multiple origins and destinations is used to compare four schemes to reduce freeway congestion: (R) ramp control only; (T) one lane is tolled and ramps are uncontrolled; (B) bottlenecks are tolled and ramps are uncontrolled; (RB) ramps are controlled and bottlenecks are tolled. In the base case no ramps are metered and there are no tolls. It is found that (T) is inefficient and likely to leave all travelers worse off than in the base case; (R), (B) and (RB) can achieve efficient freeway utilization; (B) can eliminate queues, but has adverse spatial and equity side effects; (RB) minimizes these side effects. (RB) is likely to be much less costly to implement and maintain than (T) or (B).
One of the selling points of the new 787 is lower maintenance costs. Because the composite airframe won't corrode or rust, Boeing says the maintenance costs will be cut by thirty percent. They also say that detailed visual inspections on a periodic basis should be sufficient to detect serious damage to the composite material.
While there is a lot of weight behind the argument that composite materials are not as well-studied as aircraft aluminum, the reasoning behind the flurry of recent articles may be faulty. First off, if a plane crashes, the composite frame will definitely not be the only source of toxic fumes. Second, high performance composites have been used in fighter aircraft and for years. Sports cars, race cars, and train cars made from composite materials have endured fantastic crashes. Claims that the impact toughness of carbon fiber is inadequate may be premature.
LA Times columnist Dan Neil devotes special attention to each and every one of his fifty selections for the worst automobiles ever built in his article for Time.com.
This week's Transportation Seminar features ITS Berkeley alum, Dr. Jacob Tsao, who now teaches at Department of Industrial & Systems Engineering . He'll discuss current research in automated trailer steering. Triple trailer trucks, such as the one shown above, now operate in 20 states in the U.S. Problems with safety and inefficiency due to improper tracking can be reduced or eliminated with automated trailer steering. Improving Safety of Large-Truck Operations with Automated Trailer Steering For Fuel Efficiency,Emission Reduction and Productivity examines the fuel efficiency and sustainability of truck automation.
Energy and environmental concerns have led to much attention on fuel efficiency and sustainable development. A class of large trucks called “longer combination vehicles” (LCVs) currently operates on designated highways in 20 states of the US. Although they provide high fuel efficiency and productivity, they also pose safety and infrastructure hazards. A major source of such hazards is off-tracking – the phenomenon that the rear wheels of a truck do not follow the track of the front wheels. A major category of LCVs is the Triple, consisting of a tractor and three 28-foot trailers, and some Triples also suffer from continuous sideway sway while cruising on the highway. We propose the concept of automated trailer steering to overcome these problems. Vehicle-dynamics models and steering algorithms have been developed. Computer simulation suggests that off-tracking can be virtually eliminated; it also provides a clue for the reason of the continuous sway of some Triples. Systems issues about expanding current LCV operations will be discussed as well as a new mode of freight transportation enabled by automated trailer steering – Short Trailer Combination Vehicles (STCVs).
The Transportation Seminar will be in 240 Bechtel from 4:00-5:00 PM. Cookie Hour precedes the seminar in the ITS Library, 412 McLaughlin Hall, from 3:30-4:00 PM.
The Daily Cal reports that ITS Berkeley a grant from NASA to improve the nation's air traffic control system. From the article:The campus Institute of Transportation Studies will receive $502,000 for each of two years to evaluate possible methods of relieving the nation’s overburdened aviation system.
Mark Hansen, professor of civil and environmental engineering, will be the principal investigator for the project, along with researchers at the Massachusetts Institute of Technology and University of Maryland, College Park.
Hansen said that currently air traffic controllers are often unable to predict exact arrival times of aircraft, leading to delays and causing aircraft to circle above airports because of traffic backup on the ground.
“We are studying a new case in which each airplane arrives at the airport at a specific time,” Hansen said.
There have been many criticisms of the current air traffic control system: It's out dated because they still use strips of paper (ACM, registration required). It's overburdened. Some also say the current system can be unsafe.
In response, the FAA has announced the launch of a GPS based air traffic control system. A GPS based system is certainly safer than a Buddhist based system.
