Developing adaptive and coordinated traffic control strategy to improve freeway mobility

交通挤塞和车辆废气排放是我们每天面对的两个重要社会问题。据信，减少交通拥堵会减少汽车空转，从而减少二氧化碳排放。提高高速公路交通流动性的目的是缓解交通拥堵，减少行程时间，减少温室气体排放。世界各地高速公路上日益增长的交通流量要求创新的交通控制策略和系统，以最大限度地提高现有交通基础设施的有效性和效率。因此，有一个巨大的需要了解不同的控制方法对高速公路日常运营的影响，并找到具有成本效益的解决方案，以改善现有的交通系统的性能。此外，这项拟议的研究有能力通过改善交通流动性来帮助加拿大的二氧化碳减排战略。一般的高速公路控制方法包括匝道控制、可变限速控制和路径诱导。

Traffic congestion and vehicle emission are two critical social issues we are facing daily. It is believed that reduced traffic congestion leads to reduced car idling which leads to less carbon dioxide emissions. To improve freeway traffic mobility aims to mitigate traffic congestion, decrease journey travel time and reduce Greenhouse Gas emission. Increasing traffic congestions on freeway around the world call for innovative traffic control strategies and systems that can maximize the effectiveness and efficiency of the existing transportation infrastructure. Therefore, there is a tremendous need to understand the effects of different control methods on freeway daily operation, and find the cost-effective solutions to improve the performance of existing transportation system. Further, this proposed research has the ability to help with Canada's CO2 reduction strategy through improving traffic mobility. The general freeway control methods include ramp metering control, variable speed limit control, and route guidance.
