Abstract
Traffic-signal-based speed guidance system (TSSGS) play a crucial role in the realization of sustainable urban road transportation systems. This study aims to uncover the underlying mechanisms of the TSSGS on energy consumption and traffic efficiency across different application stages. Real-time vehicle operational data were collected for three TSSGS scenarios: (1) Non-TSSGS (pre-deployment of TSSGS), (2) Prim-TSSGS (early deployment of TSSGS), and (3) Prof-TSSGS (mature deployment of TSSGS). The results revealed that Prim-TSSGS leads to increased aggressive driving behavior, decreased travel comfort, and a rise in energy consumption by 23.8% for vehicles and 30.0% for roads, attributed the lack of driver experience with the TSSGS. When drivers have a good understanding of the TSSGS, Prof-TSSGS significantly reduces the energy consumption by 29.5% for vehicles and by 23.1% for roads. This study highlights the importance of improving driver proficiency in active TSSGS to improve the sustainability of road transportation.
期刊介绍:
Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution.
We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
