Smarter Work Zone: Advancing Situation Management for Work Zone Safety and Mobility

工作区是危险的环境，会影响工人、司机和其他道路使用者的安全，并导致交通拥堵和延误。智能工作区是采用创新策略的建筑区域，以最大限度地减少对安全和流动性的负面影响。这些负面影响已经通过一系列战略、最近的实践和研究得到了广泛的研究和解决。然而，仍然需要一个集成系统来提供建筑和交通系统两个世界之间的无缝连接。这种集成系统需要实现道路（即物理系统）、信息和通信系统（即网络系统）以及人的认知、智能和社会行为（即社会系统）的工人、设备、车辆和其他用户之间的动态交互。在这样一个由人、机器和信息相互作用的复杂、多样和动态的系统中，个体或集体系统的行为取决于对情况的认识和控制（即情况管理）。

Work zones are hazardous environments that can affect the safety of workers, motorists, and other users of roadways and cause traffic congestion and delays. Smart Work Zones are construction zones with innovative strategies to minimize the negative safety and mobility impacts. Such negative impacts have been extensively studied and addressed through a number of strategies, recent practices, and research studies. However, there still is a significant need for an integrated system that provides seamless interconnections between the two worlds of Construction and Transportation Systems. Such an integrated system needs to realize the dynamic interactions between workers, equipment, vehicles, and other users of the roadways (i.e. physical systems), the information and communication systems (i.e. cyber systems), as well as the human cognition, intelligence, and social behavior (i.e. social system). In such a complex, diverse, and dynamic system of interacting humans, machines, and information the individual or collective system behavior depends on the awareness and control of situations (i.e. situation management). To advance the situation management models in construction, this program proposes to use models that simulate the mental ability of human cognition, such as consciousness (awareness), reasoning, memory, beliefs, adaptation, and learning. Thus, the proposed program utilizes cognitive situation management through a Cyber-Physical-Social system approach in the dynamic system of the work zone. This study will advance the state-of-the-art methods, tools, techniques, and strategies used in construction operation and management as well as the ones used in work zone traffic management. The proposed study meets the interests of governmental organizations, policymakers, and industry practitioners along with discovering fundamental knowledge in construction management. Success in this research program will result in notable economic, social, and environmental benefits for Canada through a reduction in injurious and fatal accidents, decreased traffic congestion, and reduced costly delays for construction as well as for the movement of goods and people. This program will have a targeted focus on the construction and transportation sectors with transferable outcomes to the mining, manufacturing, and agriculture industries.
