Estimation of vehicular emissions by capturing traffic variations
Proceedings of the 85th annual meeting of the transportation research board
Publication Date
Abstract
Over the past two decades, the fast growth in travel has caused serious traffic congestion, which has made vehicular emissions to increase significantly. However, it is difficult to accurately estimate and quantify emissions using the current practice because of its reliance on transportation planning models, which are based on steady state hourly average and thus incapable of capturing the effects of traffic variations in the transportation system. This paper proposes an intermediate model that better estimates the link speed by considering a set of Emission Specific Characteristics (ESC) variables of the link. The improved link speed data will then be used to estimate emissions. The intermediate model is developed using multiple linear regression analysis. It is then calibrated, validated, and evaluated using a microscopic simulation method. The evaluation results show that the proposed emission estimation method performs better than the current practice and is capable of estimating time-dependent emissions if traffic sensor data are available as model input.

EcoFusion: Energy-Aware Adaptive Sensor Fusion for Efficient Autonomous Vehicle Perception
Publication Date
Author(s)
Abstract
Autonomous vehicles use multiple sensors, large deep-learning models, and powerful hardware platforms to perceive the environment and navigate safely. In many contexts, some sensing modalities negatively impact perception while increasing energy consumption. We propose EcoFusion: an energy-aware sensor fusion approach that uses context to adapt the fusion method and reduce energy consumption without affecting perception performance. EcoFusion performs up to 9.5% better at object detection than existing fusion methods with approximately 60% less energy and 58% lower latency on the industry-standard Nvidia Drive PX2 hardware platform. We also propose several context-identification strategies, implement a joint optimization between energy and performance, and present scenario-specific results.

ControlLoc: Physical-World Hijacking Attack on Visual Perception in Autonomous Driving
Publication Date
Author(s)
Abstract
Recent research in adversarial machine learning has focused on visual perception in Autonomous Driving (AD) and has shown that printed adversarial patches can attack object detectors. However, it is important to note that AD visual perception encompasses more than just object detection; it also includes Multiple Object Tracking (MOT). MOT enhances the robustness by compensating for object detection errors and requiring consistent object detection results across multiple frames before influencing tracking results and driving decisions. Thus, MOT makes attacks on object detection alone less effective. To attack such robust AD visual perception, a digital hijacking attack has been proposed to cause dangerous driving scenarios. However, this attack has limited effectiveness. In this paper, we introduce a novel physical-world adversarial patch attack, ControlLoc, designed to exploit hijacking vulnerabilities in entire AD visual perception. ControlLoc utilizes a two-stage process: initially identifying the optimal location for the adversarial patch, and subsequently generating the patch that can modify the perceived location and shape of objects with the optimal location. Extensive evaluations demonstrate the superior performance of ControlLoc, achieving an impressive average attack success rate of around 98.1% across various AD visual perceptions and datasets, which is four times greater effectiveness than the existing hijacking attack. The effectiveness of ControlLoc is further validated in physical-world conditions, including real vehicle tests under different conditions such as outdoor light conditions with an average attack success rate of 77.5%. AD system-level impact assessments are also included, such as vehicle collision, using industry-grade AD systems and production-grade AD simulators with an average vehicle collision rate and unnecessary emergency stop rate of 81.3%.
