Big Rigs Go High Tech 288
pottercw writes "Trucking may not seem like a high-tech industry to the casual observer, but major carriers are starting to adopt an array of emerging technologies to combat rising fuel costs, tighter regulation and fierce competition. The technologies include systems that monitor and communicate vehicle conditions and performance, enhanced GPSs that keep tabs on tractors and trailers, and safety systems which issue warnings or even take action to help drivers avoid an accident — all working in real time. Computerworld has a cool mouseover diagram highlighting some of the gadgets we're beginning to see on high-tech trucks."

If you look at the emissions associated with the delivery of a new TV, most of it is in the last leg from the store to the buyer's home. Trucking 500 TVs across the state using a big rig produces less emissions per TV than that last ride home.

My beef with the EPA and the government is how they handled the enforcement of the 2007 emissions law. In Europe they have the Euro emissions standard for diesel engines and they are currently at Euro 5. But that does not mean that truck makers must only offer Euro 5 engines to its customers. See the EU was smart and rather then force everyone to switch they said you can still buy Euro 4 and 3 engines but you pay higher registration fees and I believe even higher road usage taxes (can anyone clarify?) for the Euro 3 and 4 engines.
In the USA the EPA forced all the engine makers and truck makers to only offer 2007 emissions rated engines in all trucks made after October 2007. Now the 2007 rated engines add another six to eight thousand dollars to a truck so guess what happened? Thats right, in 2006 trucking companies scrambled to purchase pre-2007 trucks not only because they were cheaper but the reliability of 2007 engines was unknown and untrusted. So now you have plenty of 2006 sales but sales were dead in 2007 threatening truck makers here in the states. If the EPA did what the EU did they would have eased the pain in transitioning and we would have more cleaner trucks on the road.
Now just wait till EPA 2010 when we will most likely combine the 2007 DPF and EGR systems with a selective catalytic reduction (SCR) system. Also Europe will combine a DPF system with their Euro 5 SCR/EGR system for Euro 6 emissions. At that point diesel engines will be cleaner than gasoline engines.

But that requires very precise dispatching and monitoring, so only the biggest companies with the best inventory systems can handle. Hopefully with technology getting cheaper more companies will do this and more geeks will get jobs in the freight industry running those systems.

It'd be so easy to make a few small aerodynamic changes to the trailers. That's seriously low hanging fruit, and it's been almost entirely ignored.
Aero Trailers are not always feasible in the eyes of the trucking industry for one simple reason: weight. Most tractors today have proper wind deflectors on top to allow to the air to deflect around the trailer reducing drag. Side skirts have been tried since the 70's but did not yield enough of an increase in fuel savings to warrant their cost or added weight.
We'd also see lighter trailers with more aluminum and composite carbon fiber in them
Trailers are already as light as possible and are full of composite materials and aluminum, you just haven't bothered to look. Aluminum is popular in flatbed trailers that can be upward of 100% aluminum and many trailers are of a mixed construction of both aluminum and steel. Aluminum frames used to be popular in trucks of the 70's. But after a few years of running on roads that are salted in the winter, everyone learned real fast that aluminum was a poor material for frames. Carbon fiber isn't a material your going to find on a truck as it has no desirable properties other then low weight.
more efficient engines
Diesel engines have for years been very efficient. The average today is about 6-6.5 MPG for tractor trailers. Older diesels that were mechanical could also yield similar numbers but were very dirty (but fun and simple to maintain and work on). EPA 2007 and the looming EPA 2010 has created a whole new school of diesel design and many companies are about to or are going to release some real seriously high tech engines. Compacted graphite iron, turbo compounding, ingenious heat management, acoustic tuning, over head cams and integrated engine brakes is whats in the mix. International's MaXXForce, Detroit Diesel's DD15, and Paccar's MX engine are some of the most technologically advanced engines out there. They are ready to be deployed soon here in the USA and will meet EPA 2010 emissions which will make gasoline engine look filthy.
and better tires.
Ever hear of super singles? They are wide base tires that replace the dual tires found on both drive and trailer axles. They have less friction than a set of dual tires and can bring about a noticeable and beneficial savings in fuel economy. They are also lighter which allows the truck to carry more fright which increases efficiency. Adoption has been pretty good but safety is a bit of a concern as with duals if one tire blows the other can support the weight of the axle so the truck can be safely stopped. Cost is also an issue and they aren't useful outside of LTL, long haul and bulk haul. Vocational work still demands dual tires for the high weights and abuse involved.

Regrooved tires are dangerous in general, and there's no benefit to using them. It costs a lot more to have a tire truck come out than to just buy a retread (not regroove) tire and have it done at a shop. You can't use retreads on the steering axle, and many trucking companies don't use them on the drive axles. Trailers are a different thing - you can go cheap on trailer tires because if one blows out, you can still go down the road for a bit. The other seven are adequate for getting you to the nearest tire shop.
Now as far as the "dirty and unsafe" part - that doesn't describe the modern trucking industry. Most trucks on the road are less than five years old, with hardly any older than ten. Emissions have been lowered dramatically compared to the old days, and the new fuels are almost sulphur-free. The black stuff you see coming from the stacks? That's soot - unburned carbon. It's not particularly dangerous, although it can contribute to smog. You only see that when the engine is doing something dramatic, like changing gears or taking off. Most of the time a truck is in motion, the engine is working as efficiently as possible and minimizing unburned fuels.
Most trucks are moving towards having small "lawnmower" engines called APUs (axillary power units) that power the heat/AC system and provide electricity when the truck would normally be idling. I don't have one, but hopefully I will when the lease runs out on my truck. (You have to idle or have one of these APUs in inclement weather - a trucker needs to be fully rested to drive, and that's hard when you're in a truck in the middle of the desert during the summer with no A/C. Not that California cares.)
Drivers have strict rules they have to follow regarding hours of service and inspections, and while every driver breaks the rules from time to time, you develop a sense of when you need to get off the road. A wreck can destroy your career, and equipment failure can delay your load (and your paycheck). DOT inspects trucks randomly, and they're pretty thorough. Safety is a huge concern for truckers as well as trucking companies, since accidents translate to lost money. It's not worth pushing your drivers past the rules, since DOT can audit you at any time and any accident can turn into a million dollar lawsuit.
Bear in mind this article is talking about the port of Los Angeles, which just recently banned owner-operators and trucks more than a few years old. California is a very truck-unfriendly state in general and I wouldn't be surprised if this article you pointed out was just propaganda pointing out the worst case.

Most trucking companies with their own trucks have regulators in them with limit the speed to California highway spec for semis(I think 55). Swift is the biggest one I can think of that does this. These companies generally charge per-hour or trip, and not per hour, which also minimizes speed. They also have pretty good safety enforcement, and trip monitoring. The ones to worry about are the independent contractors. They are paid per mile, or make money based on the speed of their delivery, thus have an incentive to speed, and be reckless. They also have far less safety and maintenance requirements than corporate drivers.
The margins in modern trucking are pretty damn slim, so sometimes people cut corners.
If you want to be afraid, just wait until the foreign trucking provisions of NAFTA come through, and we're flooded with Mexican truckers, driving Mexican trucks, completely immune to American safety, and EPA standards, much less CDL standards.
Most of my "bad trucker" experiences were due to morons in cars acting recklessly. People don't realize that trucks have a MASSIVE stopping distance, miles of blindspots, and the empty trailers REALLY suck. I see so many people change lanes 10ft in front of trucks going 75mph, thinking it is safe. Sometimes I hope that something terrible happens, just so I can feel good about Darwin.

My city is 550 square miles, not counting the suburbs (around 9000 square miles, including the full metropolitan area), and has around 2000 people per square mile. Compare to New York city, with 300 or so square miles, with TWICE the population (27,282 per square mile, more and an order of magnitude larger).
Most cities in the west are huge sprawling behemoths. Even with public transportation, it still would add around an hour to the average commute, or more. Sadly, Phoenix doesn't even really have that. Our bus service is spotty, infrequent, and unreliable, and barely covers most of the central part of the city, much less the outskirts.
We also have the same problems as other cities, the closer to the city center (thus jobs) you are, you either have to cope with high prices, or nasty ghetto. The only middle-class compromise is to move further and further out, thus increasing trip times, and eliminated public transit as a viable, and timely option. Statistically, only 3% of people in Pheonix use public transit to commute, while 72% drive their own cars to work.
