加拿大萨省共有17万公里各级道路,其中包括2.6万公里省管公路。与其他省(一些省将道路养护工作承包给公司,还有一些省把其中一部分承包出去,另一部分自己来做)不同,萨省的冬季道路养护全部由省交通部门的人员和设备来做。服务水平分级,是萨省关于冬季道路养护的一个非常关键的政策。冰雪消除情况、道路积雪的控制、其他附属工作等,都要遵循服务等级政策。
Saskatchewan Canada has a total of 170,000 kilometers of roads at all levels, including 26,000 kilometers of provincial highway. Unlike other provinces (where some provinces contracted road maintenance work to the company and some contracted out some of them and others did it themselves), winter road maintenance in Saskatchewan was all done by personnel and equipment from the provincial transportation department. The grading of service levels is a crucial part of Saskatchewan’s winter road maintenance. Ice and snow removal, road snow control, other ancillary work, etc., must follow the service level policy.
