[E4-05] Effect of Speed Control for Travel Time and Emission Reduction in Connected Vehicle Environment
Keywords:Connected vehicles, Vehicle queue estimation, Speed guidance, Vehicle-to-X communication
An increasing number of speed control methods at signalized intersections have been developed integrating geographic information with vehicle speed guidance technology. However, efforts to reduce travel delay time and emissions of vehicles traveling through multiple intersections are limited. To address this gap, this article aims to develop a new speed control model considering multiple intersections and evaluate the effect of the speed control scenarios on travel time and emission reduction. For this purpose, first, we develop the speed control model considering multiple intersections based on Vissim, by utilizing the traffic signal timing information and vehicle platoon data. Second, we varied the number and range of intersections that were simultaneously controlled and compared the performance of the speed control in different scenarios. Third, the performance of the speed control is also evaluated by travel time and emission reduction considering traffic volume and the proportion of connected vehicle. The results of this study will provide valuable insights for traffic engineers aiming to construct effective intelligent traffic system.
