The manual establishes clear and consistent guidelines for municipalities and contractors to achieve an acceptable level of safety balanced with cost and environmental impacts of chlorides and abrasives on Maine’s land and water resources by promoting the understanding of the tools, best practices, and limitations for snow and ice control. The manual will also help snow and ice control professionals increase their understanding of when to use and when not to use these tools and practices. In addition, it encourages progressive changes in snow and ice control practices that will help reduce salt/sand use and environmental impacts while meeting the safety and mobility needs of roadway users. By adopting and following the standards, snow and ice control professionals can show due diligence in their snow removal The Triple Bottom Line: practices. The underlying issues in snow and ice control are public health and safety, This manual provides options for consideration and presents

But CN Doors is no ordinary small town garage door installation and service company. Based out of Yellowknife in the Northwest Territories (NWT) of Canada and servicing neighboring Nunavut, CN Doors services a geographical area of 1.3 million square miles – equal in size to ½ the contiguous 48 US States. Launched in 2004, the company is, according to Colin Cleveland, Operations Manager and co-owner of CN Doors, a specialist in servicing the arctic market. “Our tech guys routinely fly in with the Ice Pilots of Buffalo Air and drive the same ice roads as the Ice Road Truckers,” notes Cleveland. The market north of the 60th parallel lives and dies by the seasons.

  • Road Weather Condition Estimation Using Fixed and Mobile Based Cameras
    Road Weather Condition Estimation Using Fixed and Mobile Based Cameras Koray Ozcan1(&), Anuj Sharma1(&), Skylar Knickerbocker2(&), Jennifer Merickel3(&), Neal Hawkins2(&), and Matthew Rizzo3(&) 1 Institute for Transportation, Iowa State University, Ames, IA, USA {koray6,anujs}@iastate.edu 2 Center for Transportation Research and Education, Ames, IA, USA {sknick,hawkins}@iastate.edu 3 University of Nebraska Medical Center, Omaha, NE, USA {jennifer.merickel,matthew.rizzo}@unmc.edu Abstract. Automated interpretation and understanding of the driving environment using image processing is a challenging task, as most current vision-based systems are not designed to work in dynamically-changing and naturalistic real-world settings. For instance, road weather condition classifica- tion using a camera is a challenge due to high variance in weather, road layout, and illumination conditions. Most transportation agencies, within the U.S., have deployed some cameras for operational awareness. Given that weather related crashes constitute 22% of all vehicle crashes and 16% of crash fatalities, this study proposes using these same cameras as a source for estimating roadway surface condition. The developed model is focused on three road surface con- ditions resulting from weather including: Clear (clear/dry), Rainy-Wet (rainy/slushy/wet), and Snow (snow-covered/partially snow-covered). The camera sources evaluated are both fixed Closed-circuit Television (CCTV) and mobile (snow plow dash-cam). The results are promising; with an achieved 98.57% and 77.32% road weather classification accuracy for CCTV and mobile cameras, respectively. Proposed classification method is suitable for autono- mous selection of snow plow routes and verification of extreme road conditions on roadways.

IRivers in the Montreal area burst their banks and submerged communities. In one community, a local pedestrian pier was completely submerged under 3 feet of water for 2 weeks. After the flood waters subsided, there was visible damage to the pier. There were several areas on the pier where the interlocking brick walkways had collapsed, indicating the presence of voids. Inspection of the vertical walls of the pier revealed cracks, further increasing concern that additional structural substrate had washed away. Local municipal officials were concerned that the pier may have more voids that could collapse, causing injury to pedestrians. The municipality contracted a Quebec-based Surface of pier showing concrete and interlocking brick surface materials and a void. geophysical service-provider to scan the pier and report The LMX200 ® was used to collect 12,500 feet of data on a pier that had suffered damage after extensive flooding. any problem areas. SUBSURFACE VIEWS OCTOBER 2017 2 The contractor had initially considered using electromagnetic induction to look for the voids; however, there were many metallic obstacles on the pier, including garbage cans and benches, that would interfere with the results. Instead, they decided to use GPR since the results would not be impacted by these metallic objects.

  • Managing the Safety of Ice Covers Used for Transportation in An
    MANAGING THE SAFETY OF ICE COVERS USED FOR TRANSPORTATION IN AN ENVIRONMENT OF CLIMATE WARMING Don Hayley, EBA Engineering Consultants Ltd., Kelowna, BC, [email protected] Sam Proskin, EBA Engineering Consultants Ltd., Edmonton, AB, [email protected] RÉSUMÉ Cet article propose une revue des risques inhérents à la gestion sécuritaire des routes de transport sur couvert de glace. La plus longue et la plus sollicitée des routes de glace du Canada dessert l'industrie minière de diamant dans la partie centrale des Territoires du Nord-Ouest et s’étend jusqu’à la région de Kitikmeot au Nunavut. La tendance climatique au réchauffement que vit le Canada a pour effet de raccourcir la saison d’opération de ce type de route à un moment où la demande du trafic est proche de la limite opérationnelle et tend encore à s’accroître. L’article décrit les améliorations apportées à l'efficacité des routes de glace par le développement de technologies pour améliorer la capacité structurale et par une gestion rigoureuse des risques. Ces améliorations permettent de gérer efficacement une plus grande incertitude sur les conditions d’exploitation tout en maintenant la priorité sur la sécurité des usagers. ABSTRACT This paper reviews some of the unique geohazards inherent in developing safe operating procedures for infrastructure reliant on ice covers. Canada’s longest and most heavily used ice road services the diamond mining industry in central Northwest Territories extending into the Kitikmeot region of Nunavut. A climatic trend to a diminished operating season is evident at a time when traffic demand is near the operational limit and future traffic growth is predicted.
