Let’s Make our Supply Chain Cheaper & Safer

By: Carl Wicklund

Does fuel efficient or eco-driving result in safer driving?

It comes as no surprise that the worldwide supply chain of materials and goods (and all our Amazon Prime deliveries) would grind to a halt without the trucking industry. The costs for consumers are directly impacted by the number of stops in the supply chain, and the transportation costs of getting from point A to point B.

Two of the largest expenditures for trucking companies today are fuel consumption along with vehicle maintenance and repairs from wear and tear, and collisions. The good news is that efforts by the trucking industry to control costs can result in financial savings along each stop in the supply chain and, ultimately, for consumers. As such, some companies are encouraging drivers of big rigs to adopt an eco-driving style when traversing the vast and diverse roadways of North America, because it just makes economic sense.

So, what is an eco-driving style?

Also known as fuel-efficient driving, an eco-driving style is aimed at using less fuel and having a smaller environmental impact. Some key principles of an eco-driving style include driving at an appropriate speed, avoiding hard acceleration, braking, or cornering, and choosing a route that has fewer stops and uneven terrain.

Now, many of us have had the experience of gradually pulling away from an intersection when the light turns green only to be left in the dust of a rapidly accelerating vehicle beside or behind us. It’s also usually no surprise to see that same vehicle sitting at the next red light as you gradually pull up. What is perhaps more of a head-scratcher is when the driver repeats the behaviour when the signal turns green, only to again end up sitting at the next red light. You don’t need to be an engineer to know the drag racer consumes more fuel, wears out their brake pads sooner, and puts everyone on or near the roadway at risk.

It isn’t cheap to operate a big rig

Fuel. The price of fuel fluctuates almost daily it seems, but it has remained exceptionally high in the last few years. I’m old enough to remember in the mid-1960s that gasoline in the U.S. cost around $.20/gallon (so, that’s just $.06/litre). The 1950s commercial jingle, See the U.S.A. in your Chevrolet was a relatively inexpensive reality. And unbelievably, diesel fuel was cheaper than gasoline! Those days are long gone, and it can now cost more than $90 (Cdn) to put gasoline in a 50-litre or 14-gallon tank of a mid-size car.

Now imagine the exorbitant cost of filling the tank of a semi-truck with a capacity from 125 to 300 gallons or 470 to 1,100 litres. Most of these big rigs use diesel, the cost of which has actually been higher than gasoline since about 2004, In Canada, diesel fuel being more expensive than gasoline is due in part to limited diesel refineries, high transport costs in regional markets, and diesel refineries being the same as the ones that supply home heating fuel of which consumption is dependent on the seasons and weather temperatures (think the polar vortex).

Maintenance & Repair. While diesel-powered truck engines don’t require servicing as often as gasoline-powered vehicles, the rising costs of big rig maintenance and repairs are significant. These costs can be exacerbated by the more sophisticated technologies of newer trucks such as communication tools and safety features which can drive up repair costs. Older vehicles often have more and larger parts that need repair or replacement and it can be harder to find suitable parts for them. Hard driving involving frequent speeding, braking, and cornering can also lead to more repairs sooner than would otherwise be necessary. The bottom line is that transportation companies can be more cost-competitive when they have strategies in place to reduce fuel consumption, maintenance, and collisions.

What can employers (and really all of us) do today?

Training and incentivizing drivers to modify driving styles or adopt eco-driving is a step in the right direction. For truckers, this means driving at optimal and steady speeds and avoiding speeding which increases fuel consumption. And for the rest of us, let’s think about our gas tank when we feel the urge to hit the gas and get to that red light sooner than the next guy.

This also means operating the vehicle smoothly and avoiding a lot of acceleration or deceleration and using cruise control where possible. In principle, traffic lights at many moderate-volume intersections are timed to enable vehicles to drive the speed limit from one intersection to the next without encountering a red light. Similarly, on a congested highway, try slowing down and keeping more of a steady pace instead of speeding up quickly only to stop quickly, which also prolongs the congestion. Finally, if you are driving a longer trip in the vehicle, plan your route to avoid a lot of intersections, turns and hills, if it’s feasible to do so, since this will help you keep a more consistent speed.

Eco-driving = fewer collisions

According to a recent study by the Traffic Injury Research Foundation, not only can eco-driving reduce fuel consumption and emissions, but it delivers safety benefits that ultimately increase productivity, reduce crashes, and lower insurance premiums. The study funded by Natural Resources Canada’s Greening Freight Program showed that eco-driving increases safety by reducing the odds of both hard braking or stability control events and actual collisions. Reducing hard-braking events also saves on brake wear that requires earlier than anticipated maintenance and helps ensure optimally safe braking.

Key outcomes of the study revealed eco-driving of big rigs can result in:

  • 7% reduction in the odds of a hard braking event
  • 8% reduction in the odds of a hard left-turn event
  • 8% reduction in the odds of a hard right-turn event
  • 4% reduction in the odds of a collision
  • 34% reduction in stability control events by driving in top gear with steady speeds close to 101 km/h
  • 3% reduction in hard braking events with a 1% increase in the amount of time using cruise control

Avoiding hard braking events and using in-vehicle monitoring systems can increase safety while reducing the number of collisions. To achieve greater fuel efficiency and safety, trucking companies should also provide training and education programs that promote eco-driving techniques and provide information to guide driving performance related to load, slope, shape, type of trailer, weather conditions, and rolling and mechanical resistance.

We can all agree that the trucking industry is critical to maintaining a reliable supply chain to keep the economy moving (literally and figuratively). Leadership and initiatives to more consistently adopt fuel-efficient and eco-driving practices not only reduce costs, but also make roads safer for everyone and help the environment.

About the project: The Traffic Injury Research Foundation (TIRF) with funding from Natural Resources Canada provided the information for this article by conducting a 2022 study on trucking fleets to quantify the safety benefits of fuel-efficient driving. Most companies in the study utilized in-vehicle technology to measure driver performance.
