The Need for Seamlessness
Geoff Wardle is Director of Advanced Mobility Research at Art Center College of Design in Pasadena, California. Educated first as a vehicle engineer and then as an automotive designer at the Royal College of Art in London, Geoff has had extensive experience as a professional vehicle designer across four continents and remains a passionate car enthusiast. However, because of his career in the automotive industry, Geoff became increasingly concerned about the future sustainability of this industry, personal mobility and transportation in general. With more than a decade of full-time involvement with Art Center’s Transportation Design department, in California and in Europe, Wardle has been a continual advocate for transportation designers becoming far more concerned and involved with the many other disciplines that make up mobility in its entirety, particularly in the urban environment.
Question: How do we rid ourselves of the “car or nothing” mindset?
Geoff Wardle: If you’re going to ask people to use an alternative to the car, or maybe the car is only part of their journey and they use other means of transportation as well, it has to be as seamless as possible. So people need to know that if they use their car for the first mile of the journey to the railroad station, or the transit station that they can just drive straight there, find somewhere to park, and then they can step pretty much straight onto the next transportation system. They need to know in advance whether there are likely to be any hiccups in the service. Passengers need to know that they are in control of the journey. The physical environment has to be safe. The physical environment has to be comfortable, and these are quite large tasks.
But multi-model transport works a lot in established cities already. If you go to the east coast, New York or some of the European or Asian cities; London, Paris, Tokyo, people do have a lot of options in multi-model transit. In those cities, there are a lot of people who choose not to own a vehicle because they know they have an array of buses or subways, other forms of transit, which they can hop, on and off and it all connects well. It surprises a lot of people to know how much public transit there is, for instance, in Los Angeles. And I have to say that there are huge efforts going on in Los Angeles to make it work better. There’s a way to go yet. But the issues in the past have been that each part of the system, whether it’s the surface buses, or the light rail system, they operate as autonomous systems and they don’t speak to each other. So, we’ve got the multi-model transit, but what we haven’t got is the seamlessness of being able to go from one to the other and knowing very easily how to get from point A to B in the city even if you’re not particularly familiar with the city.
Question: What do you see as the future for hybrids and electric plug-ins?
Geoff Wardle: Well, I think there’s an inevitability that we’re going to see a lot more hybrid vehicles of various categories and plug-in electrics. There are people who have significant doubts about them and then there are other people who think they are the holy grail of automobiles at the moment. The plug-in electric vehicle, plug-in hybrid, makes total sense when the source energy that creates the electricity to charge them up is clean and totally renewable and when the batteries which store the electricity for the duration of the journey, also have life cycle analysis that are totally ecologically clean. And we’re a ways away from that right now.
The vehicle companies that are investing a lot of money into R&D in hybrids and plug-in hybrids are doing the right thing because they are discovering a lot of aspects of these technologies that will be a great help later on. I run a hybrid myself and have done for a long time. I figured I’d better put my money where my mouth was and see what it means. If I were to do a complete life cycle analysis of the hybrid vehicle, it’s a little touch and go as to whether it’s better than a regular car. But I feel that in some ways that as a consumer, I’m contributing to the knowledge curve of building these. There are a number of advantages, of course, of battery electric vehicles or hybrids. The point of the vehicle itself has much lower emissions, they’re much quieter, which actually is causing a little bit of a debate now because they are too quiet. But in the long run, I think there is a great future. But as I said, it’s really dependent on the future of our source energy generation and the ability to develop batteries, which are clean and completely recyclable. My gut feeling is I have some optimism that we will see a lot more of these.
And the other thing that we have to remember is that whilst the car industry has done a fantastic job, admittedly under some protest in the beginning, to clean internal combustion engines up, the fact is that we are arguably at or beyond peak oil and quite soon the cost of oil-based products is going to start going up and up and up; at least going through a state of volatility as well. And so we really do have to figure out how to eek out the oil that we’ve got left much more efficiently than we have up to now. We’ve kind of been spoiled because a liter or a gallon of gasoline or diesel oil contains so much energy compared to it’s equivalent weight of a battery that its hands down the winner in terms of energy efficiency. The problem is, we’ve squandered it and we have used it in applications where we’ve assumed that we have finite supplies of it. That isn’t the case any longer.
So I think we’re going to see forms of hybrids which inevitably going to use internal combustion engines for a while, but in ways that greatly reduce the amount of gas consumption of those engines while they are in use.
Question: What modes of transportation have we been ignoring that we should focus on collectively?
Geoff Wardle: Well, I would say all of them really because there is not one answer that fits all. As I say, we have some cities that function quite nicely with alternative transportation systems now. If you visit a lot of those cities you’ll find that those systems are quite old. They’ve been so successful that they are pretty tired because of the economic and political climate that we live in, in say Europe and particularly in the United States, there hasn’t been so much political or economic will to invest public money in keeping those systems up to scratch. So we’ve been ignoring those in some ways.
I think we’ve been definitely ignoring in the U.S.A. the role that trains can play in the total landscape. Trains are not necessarily the most energy efficient way of getting people around under certain conditions compared to other forms of ground transportation, but on the other hand, they have the opportunity to being quite convenient, safe, and clean where I think they do have an opportunity is against air traffic particularly for cities that are only 200 or 300 miles apart using a high speed train between two cities becomes quite compelling compared to using aircraft.
Buses, I would say, offer significant opportunities, particularly in somewhere like Southern California which the predominant infrastructure are roads and highways, where it is very difficult to retrofit light rail or subways for a variety of reasons. We need to make much better bus systems. Unfortunately, compared to Europe or Asia or perhaps even on the East Coast where people are more comfortable using buses, in Southern California people would rather do penal servitude in Venezuela than actually ride on a bus. And yet, there are huge, huge advantages from a systems point of view of introducing bus fleet. And one must take their hat off to MTA in Los Angeles; they’ve been doing a fantastic job of building better bus systems and bus routes for us all to use. We need to keep on doing that.
We need to make it easier for people to make those journeys which really, they shouldn’t be using an automobile, not particularly convenient to use a bus, and certainly doesn’t make sense to use a subway. We need to consider those. And lots of people have been working with the question of the first and last mile of journey; so, helping people use bicycles, or electric bicycles, or Segways, or other very personal systems to help make those journeys. And of course we shouldn’t forget that actually the best way of getting around from a health – an ecological point of view is to walk. And we need to get better as we redevelop cities and as we build new cities to make it much more compelling for people to walk.
Of course, you can look at some cities that have done this very well, if you look at cities like Montreal, or Toronto in Canada where, of course, they have very severe winters, it’s still possible to walk around downtown, underground. It’s important. We need to make sure that people feel not only able to, but quite interested in the idea of walking. And again, I’m sure our listeners are familiar with certain cities or town in their life where it’s fun to walk places, or it’s fun to cycle somewhere. And then there are other places where it either feels threatening, or it feels dangerous, or there’s no facility to be able to walk.
Question: What are the major challenges in the realm of goods transportation?
Geoff Wardle: Well, probably the biggest challenge is, as the global economy proceeds, the cost of energy is going to, as I said earlier, is inevitably arise and it will start to make, in some ways, less and less economic sense to ship goods that are being made in one continent halfway around the world to the other. It’s already part of the daily conversations about the wisdom of drinking water that has been bottled in Fiji when you live in California or Paris, or somewhere like that. But it could also apply to a lot of other things.
So, I think with transportation, we may see a reduction in a few decades of a lot of long-distance transportation of goods as we get better and better at producing goods and food much closer to where we live. So, I think the cost of energy is going to be one of the challenges. And we see it already. Most people who complain that the cost of food in the supermarkets is going up think it’s all a conspiracy against them. It’s probably because the costs of actually transporting the goods let alone the raw materials, which have to be transported as well, are increasing quite dramatically.

Can consumers rid themselves of the "car or nothing" mentality?
The controversial herbicide is everywhere, apparently.
- U.S. PIRG tested 20 beers and wines, including organics, and found Roundup's active ingredient in almost all of them.
- A jury on August 2018 awarded a non-Hodgkin's lymphoma victim $289 million in Roundup damages.
- Bayer/Monsanto says Roundup is totally safe. Others disagree.
Can dirt help us fight off stress? Groundbreaking new research shows how.
- New research identifies a bacterium that helps block anxiety.
- Scientists say this can lead to drugs for first responders and soldiers, preventing PTSD and other mental issues.
- The finding builds on the hygiene hypothesis, first proposed in 1989.
Are modern societies trying too hard to be clean, at the detriment to public health? Scientists discovered that a microorganism living in dirt can actually be good for us, potentially helping the body to fight off stress. Harnessing its powers can lead to a "stress vaccine".
Researchers at the University of Colorado Boulder found that the fatty 10(Z)-hexadecenoic acid from the soil-residing bacterium Mycobacterium vaccae aids immune cells in blocking pathways that increase inflammation and the ability to combat stress.
The study's senior author and Integrative Physiology Professor Christopher Lowry described this fat as "one of the main ingredients" in the "special sauce" that causes the beneficial effects of the bacterium.
The finding goes hand in hand with the "hygiene hypothesis," initially proposed in 1989 by the British scientist David Strachan. He maintained that our generally sterile modern world prevents children from being exposed to certain microorganisms, resulting in compromised immune systems and greater incidences of asthma and allergies.
Contemporary research fine-tuned the hypothesis, finding that not interacting with so-called "old friends" or helpful microbes in the soil and the environment, rather than the ones that cause illnesses, is what's detrimental. In particular, our mental health could be at stake.
"The idea is that as humans have moved away from farms and an agricultural or hunter-gatherer existence into cities, we have lost contact with organisms that served to regulate our immune system and suppress inappropriate inflammation," explained Lowry. "That has put us at higher risk for inflammatory disease and stress-related psychiatric disorders."
University of Colorado Boulder
This is not the first study on the subject from Lowry, who published previous work showing the connection between being exposed to healthy bacteria and mental health. He found that being raised with animals and dust in a rural environment helps children develop more stress-proof immune systems. Such kids were also likely to be less at risk for mental illnesses than people living in the city without pets.
Lowry's other work also pointed out that the soil-based bacterium Mycobacterium vaccae acts like an antidepressant when injected into rodents. It alters their behavior and has lasting anti-inflammatory effects on the brain, according to the press release from the University of Colorado Boulder. Prolonged inflammation can lead to such stress-related disorders as PTSD.
The new study from Lowry and his team identified why that worked by pinpointing the specific fatty acid responsible. They showed that when the 10(Z)-hexadecenoic acid gets into cells, it works like a lock, attaching itself to the peroxisome proliferator-activated receptor (PPAR). This allows it to block a number of key pathways responsible for inflammation. Pre-treating the cells with the acid (or lipid) made them withstand inflammation better.
Lowry thinks this understanding can lead to creating a "stress vaccine" that can be given to people in high-stress jobs, like first responders or soldiers. The vaccine can prevent the psychological effects of stress.
What's more, this friendly bacterium is not the only potentially helpful organism we can find in soil.
"This is just one strain of one species of one type of bacterium that is found in the soil but there are millions of other strains in soils," said Lowry. "We are just beginning to see the tip of the iceberg in terms of identifying the mechanisms through which they have evolved to keep us healthy. It should inspire awe in all of us."
