Abstract
This article reviewed the impacts of vehicle emissions in urban transportation network, the existing strategies to reduce such transportation emissions, the complexity of urban transportation environment network, and the development of vehicle emission models. The vanguard research needs are also proposed in developing emission and air quality models and simulation, and emission-oriented transportation management strategies. This requires multidisciplinary research for the expectant counter-measures for urban transportation environmental network systems. Three essential tasks are proposed including: (1) improving urban air quality monitoring networks, (2) refining field-oriented emission models to better addressing real-time transportation activities, and (3) developing efficient and smart traffic control strategies to mitigate emission and improve air quality. These tasks would address the emerging issues associated with the sustainability and reliability of urban transportation environmental network, through interdisciplinary efforts represented by Science, Technology, Engineering, and Mathematics (STEM) disciplines, which would involve the knowledge of transportation, environment, mathematics, chemistry, physics, engineering technology, and computer science.
