AUTONOMOUS VEHICLES, FLYING TAXIS AND...BUSES? BALANCING PRESENT AND FUTURE NEEDS

https://ui.uncc.edu/story/autonomous...d-future-needs

Quote:

.....

- How do you plan for the future and dream big while attending to the pressing needs of the day? It’s a question that came up pointedly during Charlotte City Council’s annual planning retreat this week. With 385,000 people projected to move to Charlotte over the next couple decades, the city is grappling with increasing congestion and questions about how we’ll move around the community without spending hours a day in traffic.

- To cope, council members are considering whether to put a 1-cent sales tax increase on the ballot this November. Mecklenburg County voters would get the final say on the tax, which would provide enough revenue over the next 30 years to fund the city’s portion of an $8 billion to $12 billion transit and transportation network. Such a referendum would face hurdles, however: The state legislature and county commissioners must agree to put it on the ballot, and the mayors of Davidson, Huntersville and Cornelius have already expressed their reservations because transit has lagged in the northern part of the county.

- The priciest item on the city’s transit wishlist would undoubtedly be the 26-mile, east-west Silver Line light rail. But at the retreat, some council members asked another question altogether: Should we be focusing on autonomous vehicles, air taxis and other futuristic solutions instead? — “We can only go all in on one of these bets,” said council member Tariq Bokhari. He wants the city to focus on building the infrastructure (such as 5G service and electrical grid updates) to support self-driving cars, autonomous cargo vehicles and other technologies that are tantalizingly close but still over the horizon.

• Video Link

Thanks for video and I totally agree that regional rail is the answer for most NA cities. It's premise is basic...............make the most use of the infrastructure you already have. As you live in Toronto, I think the large Eglinton LRT project will be just a footnote compared to the monumental transformation that will COULD result from RER.

That said, I think you missed a couple major points:

First, fare integration. Suburban/RER services MUST be priced at the same level as the buses/LRT/Metros etc and be part of the standard transferable transit fare in order to make them financially viable for most of the population. Most people who ride transit are price sensitive being more working class, students, disabled, unemployed, and seniors. A doubling of fares by taking a RER is simply not optional for many.

Second, electrification. Electrification does provide cheaper operational costs than standard diesel but that depends on the context. Canada has some of the cheapest hydro rates in the Western world and are cheaper than in the US and conversely diesel/gas is cheaper in the US so the cost benefit is less. Even so, electric trains offers environmental benefits, faster de/acceleration, and are much quieter. The problem is the initial cost, construction, and time needed to build all those thousands of km of catenary is prohibitive. You should present viable options that are not just catenary but also battery and hydrogen. There is no such thing as a 'one size fits all' transit technology. If a city has 300 km of commuter rail, that does not mean they have to string 300 km of wires.

Energy-Efficient V-Shaped Ride-in-the-Wings Jetliner Successfully Took Off

https://interestingengineering.com/t...fully-took-off

Quote:

.....

- This summer, a scale model of TU Delft's Flying V jetliner took flight. The new aircraft carries passengers in its wings and reports being 20% more fuel-efficient. Project leader Dr. Roelof Vos and his team took the 22.5 kg and 3-meter wide-scale model to an airbase in Germany. There they worked together with a team from Airbus to get the aircraft to take-off, fly a number of test maneuvers until the batteries were nearly empty and landed. “One of our worries was that the aircraft might have some difficulty lifting-off since previous calculations had shown that ‘rotation’ could be an issue. The team optimized the scaled flight model to prevent the issue, but the proof of the pudding is in the eating. You need to fly to know for sure," said in a statement Vos.

- The trial was deemed a successful one as rotation on take-off was performed easily at the speed of 50 mph (80 km/h). However, as it was just an experimental model, how the real jetliner would perform in an actual flight is still uncertain. From this scale model trial, the researchers already concluded that they had to change the center of gravity of the aircraft and fix the antenna to improve telemetry. The next steps for the team are to use the data acquired during the flight to build an aerodynamic software model of the aircraft. This will mean they can test the jetliner in a flight simulator and use the outcomes for research and development. The Flying-V has been created to be a highly energy-efficient long-distance airplane. The passenger cabin, the cargo hold, and the fuel tanks have all been placed in the wings, introducing the V-shape that the plane is named after.

Aircraft Could Cut a Big Chunk of Their Emissions Just by Riding The Winds

https://www.sciencealert.com/aircraf...ding-the-winds

Quote:

.....

- Modern-day aircraft already make use of jet streams to save time and fuel, but a new study shows that by being a bit smarter about how they ride these winds, transatlantic flights could be using up to 16 percent less fuel – and pumping out much less CO2 as a result. The key is flexibility, the researchers say: allowing planes to vary their flight paths more often and to a greater extent depending on how the jet stream is moving on any particular day. Upcoming advances in satellite and tracking technology mean this can be done without adding any more risk to journeys. --- If airlines are prepared to put saving fuel above cutting costs when it comes to riding the jet stream, the low Earth orbit satellite technology needed to make this idea a reality is already in the testing phase. Up until now, the large volume of transatlantic air traffic and spotty radar coverage in the middle of the ocean has constrained what planes can do in terms of varying their routes – but that excuse isn't going to be valid for much longer.

Fixing US Transit Requires Service, Not Just Infrastructure

https://humantransit.org/2021/01/fix...structure.html

Quote:

.....

- If you want to transform public transit for the better in the US, there’s useful infrastructure you could build, but the quickest and most effective thing you could do is just run a lot more buses. Remember, US activists: Don’t just envy Europe; start by envying Canada. The average Canadian city has higher ridership than the most comparable US city, not because they have nicer infrastructure or vastly better land use, but because they just run more transit. Increasing bus service by 40% (an aspirational number that still wouldn’t match many Canadian peers) would massively expand where people could go, and thus what they could do. --- With a 40% increase in service someone in this location can reach ten times the number of jobs in 45 minutes. (These analyses use jobs because we have the data, but this means a comparable growth in the opportunities for all kinds of other trips: shopping, errand, social, and so on. ) I would argue that someone at this location would be 10 times as free, because they would have 10 times more options to do anything that requires leaving home.

.....

Here’s how 40% more service would expand where someone could get to from a particular point in metro Atlanta. (The concentric colors mean where you could reach in 10, 20, 30, or 45 minutes, counting the walk, the wait, and the ride.)

"Archer Aviation Inc. said Wednesday that United Airlines Holdings Inc. placed a $1 billion order for its all-electric vertical take-off and landing aircraft (eVTOL), on the same day the company announced a deal that will allow the public to invest in the urban air mobility (UAM) company in the coming months.

The Palo Alto, Calif.-based company said before the open that it entered into a merger agreement with special purpose acquisition company (SPAC) Atlas Crest Investment Corp. ACIC, +21.71%, which in effect will take Archer public. The company said the deal has an equity value of about $3.8 billion.

Once the deal closes, which is expected to occur in the second quarter of 2021, the combined company will be named Archer and the stock will be listed on the New York Stock Exchange under the ticker symbol “ACHR.”

New Washington transportation plan includes taxes on gas and bikes, fees on transit

https://www.seattletimes.com/seattle...es-on-transit/

Quote:

.....

- Washington drivers would pay 3 cents a gallon more at the pump to help fund road improvements and cover revenue losses caused by the coronavirus pandemic under a proposal released Friday by Republican state Sen. Curtis King. In addition, sales taxes on bicycles and bike parts would rise 2 cents on the dollar, transit riders would pay a 20-cents-per-trip surcharge and ferry passengers would pay an extra 25 cents per crossing. People taking Uber and Lyft would pay an additional 50 cents per ride. “It’s time we made everybody contribute and pay for what they use,” said King, of Yakima, the ranking Republican on the state Senate Transportation Committee who represents the 14th Legislative District.

World’s First All-Hemp Plane is 10 Times Stronger than Steel and Fueled by Hemp

https://returntonow.net/2021/02/24/w...MgWCEWYeGV6tFg

.....

- Canadian cannabis firm Hempearth has designed a plane made from and fueled by hemp oil. The body and wings of the plane are made from composite hemp fibers that are 10 times stronger than steel, according to the company. Even the interior walls, seats and pillows are made from hemp! And best of all, it’s even designed to run on 100% hemp oil, which it won’t need much of since its so lightweight! The hemp composite material used to make the body of the plane could “replace all fiberglass in aviation and many other industries,” Hempearth’s CEO Derek Kesek says. It would be lighter weight, stronger, more durable and with more flexibility/plasticity.
