Cash-strapped Alberta rethinks approach to highways

BANFF, AB - A cash-strapped Alberta government is rethinking the way priorities are set for the province's highway network and related maintenance - both for the short term and decades into the future. Every proposed infrastructure project must now contribute to a "triple bottom line" that considers social, economic and environmental impacts, Alberta Transportation Assistant Deputy Minister Shaun Hammond said in a briefing during the Alberta Motor Transport Association's annual convention. Decisions to twin a highway will be based on more than traffic counts alone. And "you will see more and more (environmental issues) in the next few months." The department is already reaching out to the association in the search for ways to reduce emissions around Red Deer, where particulates from diesel engines have played a role in creating the worst air quality in Canada. And Alberta Transportation and Infrastructure Minister Brian Mason pledged earlier in the day to begin research into fuel-saving wide-base single tires "as soon as possible".

Mason highlights transportation projects in AMTA address

BANFF, AB - Alberta Transportation and Infrastructure Minister Brian Mason spoke to the Alberta Motor Transport Association's annual conference this afternoon, emphasizing investments being made in the province's road networks. "The global collapse in oil prices, our most vital commodity, is causing tremendous economic pain and anxiety," he said, adding that the province's infrastructure investments are designed to help spur economic growth. "Transportation is vital to building the Alberta economy."

Mack boosts fuel economy under Earth Day backdrop

AUSTIN, TX - Mack Trucks' choice of the setting and day to unveil a series of powertrain upgrades was no coincidence. Austin, Texas is known for its music and barbecue, but is also recognized as one of the Top 10 greenest cities in the U.S. And April 22 marks Earth Day. Collectively, they offered a fitting backdrop for changes made in the name of fuel economy. The 2017 Mack MP engine lineup will see fuel economy jump between 2.1 and 8.8% compared to today's models, while a new Predictive Cruise will effectively memorize terrain and enhance shifts when routes are repeated. Engine upgrades include a common rail fuel system, and turbo compounding that tranforms waste heat into torque on the camshaft. Fuel-saving enhancements have certainly put the engines on a diet. The common rail fuel system, widely used in Europe, allows for an assembled camshaft that is 27 pounds lighter than its single-piece predecessor. The MP8's cylinder block is also 44 pounds lighter than today's models. Even when turbo compounding is introduced on the MP8, the engine is still 33 pounds lighter than existing models.
