New technologies have allowed the Ministry of Transportation and Infrastructure to improve safety and efficiency for travellers. To help you visualize some of the ways we’re utilizing technology, we collected some photos of our gizmos and gadgets.
Seasonal load restrictions for commercial vehicles are enforced in the spring, when temperatures rise, ice thaws and roads weaken. The ministry monitors road strength by using a handy piece of equipment called the Benkelman Beam. “Beaming” is done by placing a load on the road and measuring the rebound. This shows when the road has dried enough to regain its strength, allowing commercial drivers to resume carrying full loads without damaging the road.
National Science and Technology Week runs Oct 12-21, 2012.
