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.

基于交通信号的速度诱导系统在不同应用阶段对交通的影响

基于交通信号的速度诱导系统（TSSGS）在实现可持续城市道路交通系统中发挥着至关重要的作用。本研究旨在揭示 TSSGS 在不同应用阶段对能耗和交通效率的影响机制。研究收集了三种 TSSGS 方案的实时车辆运行数据：(1）Non-TSSGS（TSSGS 部署前）；（2）Prim-TSSGS（TSSGS 早期部署）；（3）Prof-TSSGS（TSSGS 成熟部署）。研究结果表明，Prim-TSSGS 会导致激进驾驶行为增加、出行舒适度降低，以及车辆能耗增加 23.8%、道路能耗增加 30.0%，这归因于驾驶员缺乏使用 TSSGS 的经验。当驾驶员对 TSSGS 有了很好的了解后，Prof-TSSGS 可显著降低车辆能耗 29.5%，降低道路能耗 23.1%。这项研究强调了提高驾驶员对主动式 TSSGS 的熟练程度对改善道路运输可持续性的重要性。

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.
