CHINA BUILDS A 20-ROAD INTERCHANGE FROM HELL

https://www.wired.com/story/photo-of...nge-from-hell/

Quote:
.....

- The Huangjuewan opened last month on the outskirts of Chongqing, a sprawling city in southwest China. The highest of the interchange's five levels soars 12 stories overhead, and the 20 lanes send cars this way and that. Getting the best view required standing on the roof of a building perched on a nearby hill.

An airline tried to get a musician to check her 17th-century violin. A ‘wrestling match’ ensued.
By Cleve R. Wootson Jr. June 6

. . . when a Houston-based gate agent at United Airlines told Yennifer Correia that she would have to check her 17th-century violin, which costs more than her car, the first words out of her mouth were: “What are my other options?”

. . . Correia, a classical violinist on her way to play in the summer season at the Missouri Symphony Orchestra, asked for an airport supervisor. But the supervisor said there were no other options. The violin had to be checked.

Her attorney, Phil MacNaughton, recounted what happened from there. Correia told the supervisor, “I can’t not take my violin on board. I’ll pay the money. I’ll take another flight. Just tell me what I can do” . . . .

“Without provocation, the supervisor for the Chicago-based carrier then lunged for Ms. Correia’s case and, incredibly, tried to wrestle it away from the musician,” said a statement written by MacNaughton.

“I start screaming, ‘Help, help, help, can somebody record what’s happening because this lady’s trying to take my personal suitcase from me,’” Correia told Houston NBC-affiliate KPRC.

The supervisor said she was going to call security, and Correia apparently responded, “Please do.” Then the supervisor dashed off. That was the last Correia saw of her.

During the scuffle, MacNaughton said, Correia’s hand was injured. She doesn’t believe there is permanent damage, but she went to see a hand specialist “because the stakes are high” . . . .

Federal law requires airports to accommodate musicians who want to carry their instruments with them in the airplane’s cabin. MacNaughton said he’s not certain whether United officials violated that law.

City planners float idea of subway tunnel through downtown Portland

Read More: http://www.oregonlive.com/commuting/...nnel_thro.html

Quote:
.....

Portland-area transportation planners are looking underground for a potential big-ticket project: a subway that runs beneath the downtown core and across the Willamette River. City transportation officials floated the idea Tuesday in a presentation before the Portland Planning and Sustainability Commission.

- The concept, represented on a map by a meandering line with no clear endpoints, is clearly far from reality. Though much of the presentation outlined smaller transportation projects over a 20-year timeline, Portland Bureau of Transportation spokesman Dylan Rivera said any subway project would be at least 30 to 40 years away. But the presentation does indicate the subway is on a track to be included on an update to the Regional Transportation Plan next year, a requirement if the project is to receive future federal funding.

China's 'straddling bus' hits its final roadblock

http://www.bbc.com/news/world-asia-china-40365161

Quote:
.....

- It seemed like a glimpse into the city of tomorrow - but China's "straddling bus" was riddled by doubts early on and now is headed for the scrap yard. The futuristic idea was a bus that would drive above traffic, allowing other commuter cars to pass underneath. The project was announced last summer to much acclaim but soon ran into feasibility and investment problems.

- Many of China's cities suffer from chronic traffic congestion so there's a strong hunger for ingenious solutions. The project faced strong headwinds from the very beginning and according to Chinese media, the test site is now being demolished entirely. Reports are saying that workers have already begun dismantling and removing the test track in Qinhuangdao.

Cooling the tube – Engineering heat out of the Underground

Read More: https://www.ianvisits.co.uk/blog/201...e-underground/

Quote:
.....

The “tube” can be split into two types of service — the tube proper which runs through tube tunnels, and the older sub-surface lines which are just below street level. The older sub-surface tunnels were built for steam trains, so had loads of big holes in the ground included in the design to deal with removing smoke, and they are also much larger than tube tunnels. This has allowed the London Underground to fit air-conditioning units to its new fleet of sub-surface trains.

- However, it’s the deep level tube tunnels that cause the biggest problems for both passengers suffering the heat, and London Underground in getting rid of it. The deep level tunnels suffer a number of problems which are individually a nuisance, but collectively add up to show why there is such a huge problem cooling the Underground. One of the biggest problems is a side-effect of what made it possible to dig the deep level tunnels in the first place — namely the very solid and nice to tunnel through London Clay which sits under the city.

- In fact, when the early tube tunnels were dug, they were so cool down there that the cool tube was seen as a respite from the summer heat on the surface. Why suffer on a bus in the heat when there’s a cool tube to take instead, said the marketing men. So why is the Bakerloo line, once the coolest place to be, now a mobile sauna? While that heavy thick clay is lovely to tunnel through, it is also a heat insulator. Over the years, the heat from the trains soaked into the clay to the point where it can no longer absorb any more heat.

- About 21% of the heat in the tunnels comes from the movement of the trains themselves, from aerodynamic drag and other frictional losses. The motor engines account for 15%, the electrical and auxiliary systems are the remaining 12%. About half the heat in the tunnels though comes from just one source –from the trains slowing down — the conversion of movement into heat by applying the brakes. So it can be seen that cutting the heat from applying the brakes is where the biggest win would be, and indeed, the use of regenerative braking now converts about half the heat loss back into electricity.

- However, that can only work where trains are accelerating and braking at the same time, on the same electricity sub-station loop. Experiments have been underway to improve that by use of an inverting substation, supplied by Alstom, which can send unused power from braking trains back into the national grid. --- By the time the Victoria line came along, the engineers were very well aware of the problem and it was built with considerably more ventilation shafts than older tunnels would have been supplied with. Although it varies depending on location, in general cooler air is sucked down through the stations, and then ventilation shafts in the tube tunnels sucks out the hot air.

Commentary: Lyft Shuttle eliminates those pesky poor people
By ANN FRIEDMAN
PUBLISHED: June 27, 2017 at 7:05 am | UPDATED: June 27, 2017 at 9:15 am

The ride-hailing company Lyft rolled out its new shuttle service this month, allowing users in San Francisco and Chicago to “ride for a low fixed fare along convenient routes, with no surprise stops.” Some were quick to identify this supposed innovation as a bus . . . . whatever we call it, Lyft Shuttle is just another way that wealthier Americans are paying for reliable and convenient services rather than demanding improvements to existing public goods.

Services like Lyft are also giving customers the ability to live insulated from those who have less money. That’s a time-honored tradition . . . .

Are those blades for wind turbines next to the test tracks? Those things are HUGE! That's more impressive than the "train," I think.

Niagara to Toronto via hovercraft? Ontario man's proposal inches forward

http://nationalpost.com/news/canada/...3-9da9fff9212b

Quote:
.....

- Ideas for a cross-lake commuter service have been floated for years, but none has ever found success. A fast-ferry service from Toronto to Rochester, N.Y., ran briefly in 2004, but eventually failed due to financial troubles. But St. Catharines Coun. Carlos Garcia says that using a hovercraft instead of a traditional boat changes the situation. --- "The hovercraft is much more flexible because it can crawl up on land and doesn’t need docking facilities as other vessels do,” said Garcia. The hovercraft is also able to traverse ice during the winter, and doesn’t create a large wake in the water like larger ferries.

- PortsToronto said it has no current plans to proceed with the hovercraft service due to noise concerns. However, Caciagli says that the hovercraft would only create as much noise as an idling semi truck. Caciagli says he’ll continue to push forward with the plan despite the roadblock with PortsToronto. He says he’d also consider nearby alternate ports, if need be. --- Toronto Coun. Michael Thompson, on the city’s economic development committee, says he’d consider that level of noise “reasonable.” Hovercraft or not, he says that getting transport on Lake Ontario is the right idea to relieve congestion and save travel time.

An All-Too-Rare Idea to Improve Transit: Put People Who Ride Transit in Charge

http://usa.streetsblog.org/2017/06/3...sit-in-charge/

Quote:
.....

- The Dallas City Council’s house-cleaning of DART representatives this week signals a wise pivot to what matters most: Ensuring that the regional transit agency lures new customers and does right by those who rely on its service, yet too often are let down. --- The newcomers named on Wednesday are formidable choices, based on their credentials and interviews earlier this month. All of them are frequent Dallas Area Rapid Transit users, and each showed an understanding of the agency as well as the shortcomings that consistently bedevil Dallas residents who must depend 24-7 on the system. The appointees’ answers reflect fresh, practical ideas for improvements, while long-time board members voiced a relatively hands-off approach to DART accountability.

Arrests over China 'straddling bus' project

http://www.bbc.com/news/world-asia-china-40492697

Quote:
.....

- Police in Beijing have arrested 32 people for illegal fundraising linked to a scrapped project to create a "straddling bus" to beat traffic jams. The futuristic idea to lift commuters above congestion quickly attracted international attention when it was launched last year - but was finally scrapped last month. There had been growing speculation that it was no more than an investment scam. In a statement, police said they were working to recover investors' assets.

Trainy McTrainface: Swedish rail firm approves name following online poll

https://www.theguardian.com/world/20...r-of-its-fleet

Quote:
.....

- A Swedish rail operator has vowed to name one of its trains Trainy McTrainface after a public vote, saying it would bring joy to people disappointed when Britain rejected the name Boaty McBoatface for a polar research ship following a similar poll. Trainy McTrainface won 49% of the votes in the naming competition, conducted online by train operator MTR Express and Swedish newspaper Metro, beating choices such as Hakan, Miriam and Poseidon. --- “[This is] news that will be received with joy by many, not just in Sweden,” MTR wrote in a statement. The train will run between the Swedish capital Stockholm and Gothenburg, the country’s second-biggest city.

Best part of that pic isn't the train (tho I love the color scheme), it's the building next to the train. Because it will be torn down and replaced (along with the roof on the left) as part of a coming re-development and over-decking plan made possible by the commuter trains moving down to a new underground station below the subways.

CAN FORD FIX NEW YORK CITY’S TRANSPORTATION CRISIS WITH A CROWDSOURCED SHUTTLE BUS?

https://www.theverge.com/2017/7/27/1...it-shuttle-bus

Quote:
.....

- Starting soon, Ford is launching its on-demand shuttle bus service Chariot in New York City. The self-described microtransit service will start out in preplanned service areas in Manhattan and Brooklyn, eventually adding routes in additional neighborhoods based on customer crowdsourcing. It’s not a new idea — Via, an app-based communal bus service, has been operating in the city since 2015 — but Chariot has high hopes that its approach to ride-sharing will catch on.

- Chariot may have found an audience in tech-friendly cities like San Francisco, Seattle, and Austin, but New York City is a different beast altogether. The subway is one of the oldest (113 years old) and largest (daily ridership of 6 million people) in the world. It’s also broke as hell: it rains sewage, derails constantly, traps passengers in sweltering prisons, and all New Yorkers can do is shake our fist at the sky, tweet impotently, and then saddle up for another ride the next day.
