For cyclists, being overtaken represents a safety risk of possibly being side-swiped or cut in by overtaking drivers. For drivers, such maneuvers are challenging–not only do they need to decide when to initiate the maneuver, but they also need to time their return well to complete the maneuver. In the presence of oncoming traffic, the problem of completing an overtaking maneuver extends to balancing head-on with side-swipe collision risks. Active safety systems such as blind-spot or forward-collision warning systems, or, more recently, automated driving features, may assist drivers in avoiding such collisions and completing the maneuver successfully. However, such systems must interact carefully with the driver and prevent false-positive alerts that reduce the driver’s trust in the system. In this study, we developed a driver-behavior model of the drivers’ return onset in cyclist-overtaking maneuvers that could improve such a safety system. To provide cumulative evidence about driver behavior, we used data from two different sources: test track and naturalistic driving. We developed Bayesian survival models for the two datasets that can predict the probability of a driver returning, given time-varying inputs about the current situation. We evaluated the models in an in-sample and out-of-sample evaluation. Both models showed that drivers use the displacement of the cyclist to time their return decision, which is accelerated if an oncoming vehicle is present and close. We discuss how the models could be integrated into an active-safety system to improve driver acceptance.
对于骑自行车的人来说,被超车意味着安全风险,可能会被超车的司机侧滑或剐蹭。对于驾驶员来说,这种超车动作极具挑战性,他们不仅需要决定何时启动超车动作,还需要把握好返回的时间以完成超车动作。在迎面来车的情况下,完成超车动作的问题还包括平衡正面与侧面碰撞的风险。主动安全系统,如盲点或前撞预警系统,或最近出现的自动驾驶功能,可以帮助驾驶员避免此类碰撞并成功完成超车动作。然而,此类系统必须谨慎地与驾驶员互动,防止出现错误警报,从而降低驾驶员对系统的信任度。在本研究中,我们开发了一个驾驶员行为模型,用于分析驾驶员在骑车超越行人时的回车起始点,从而改进此类安全系统。为了提供有关驾驶员行为的累积证据,我们使用了两个不同来源的数据:测试轨道和自然驾驶。我们为这两个数据集开发了贝叶斯生存模型,该模型可在当前情况的输入随时间变化的情况下预测驾驶员返回的概率。我们对模型进行了样本内和样本外评估。两个模型都表明,驾驶员会利用骑车人的位移来确定其返回决策的时间,如果迎面而来的车辆出现且距离较近,则会加速其返回决策。我们讨论了如何将模型集成到主动安全系统中,以提高驾驶员的接受度。

With the rise of intelligent transportation, various mobile value-added services can be provided by the service provider (SP) in the Internet of Vehicles (IoV). To guarantee the dependability of services, it is essential to implement a mutual authentication protocol between the vehicles and the SP. Existing mutual authentication protocols to secure the communication between the SP and the vehicle raise challenges such as providing fine-grained forward security for the SP and achieving backward security for the vehicle. To handle these challenges, this paper proposes a conditional privacy-preserving mutual authentication protocol featured with fine-grained forward security and backward security for IoV, which can be implemented via two building blocks we have constructed. Specifically, we present a new puncturable signature (PS) scheme without false-positive probability and the update of the public key as well as the first proxy re-signature scheme with parallel key-insulation (PKI-PRS). What’s more, both the proposed PKI-PRS and PS still have interest beyond this protocol. Then, an anonymous mutual authentication protocol with resistance to key leakage is constructed by incorporating the above signature schemes. The proposed protocol not only provides fine-grained forward security for the SP, but also ensures forward security as well as backward security for the vehicles. Besides, the approach to achieving anonymous authentication can efficiently provide conditional privacy-preserving for the vehicles. With the support of the random oracle model and experimental simulations, the formal security proof and the superiority of the proposed protocol is explicitly given.
随着智能交通的兴起,服务提供商(SP)可以在车联网(IoV)中提供各种移动增值服务。为了保证服务的可靠性,必须在车辆和 SP 之间实施相互验证协议。现有的相互认证协议在确保 SP 和车辆之间的通信安全方面存在一些挑战,例如既要为 SP 提供细粒度的前向安全性,又要实现车辆的后向安全性。为了应对这些挑战,本文提出了一种有条件的隐私保护相互认证协议,它具有细粒度的前向安全性和面向物联网的后向安全性,可以通过我们构建的两个构件来实现。具体来说,我们提出了一种新的无假阳性概率和无公钥更新的可标点签名(PS)方案,以及第一种具有并行密钥隔离(PKI-PRS)的代理重签名方案。此外,所提出的 PKI-PRS 和 PS 在本协议之外仍有其他意义。然后,结合上述签名方案,构建了一个具有抗密钥泄漏能力的匿名相互认证协议。所提出的协议不仅为 SP 提供了细粒度的前向安全性,还确保了车辆的前向安全性和后向安全性。此外,实现匿名认证的方法还能有效地为车辆提供条件隐私保护。在随机甲骨文模型和实验模拟的支持下,明确给出了所提协议的形式安全性证明和优越性。

In most studies on modeling driving behavior at uncontrolled intersections, multi-vehicle interaction scenarios are usually categorized and modeled separately as moving-across behavior and merging behavior. However, it is inappropriate to use a single-behavior model to accurately represent general driving behavior in uncontrolled intersections. In this case, we constructed a general driving behavior model for multi-vehicle interaction at uncontrolled intersections. Initially, the IMM model is employed to anticipate the movement of the vehicle within the driver’s visual field. The risk field theory is applied to assess potential hazards that the vehicle might confront, drawing from the risk homeostasis theory and preview-follower theory, which aids in determining a trajectory that aligns with the drivers’ real-life actions while also meeting the risk constraints. Drivers’ heterogeneity is reflected by risk threshold. This model can simulate driver behavior in traffic congestion at uncontrolled intersections by adjusting risk thresholds when the vehicles are caught in a deadlock situation. Results show that our model can accurately reproduce the priority and trajectory of vehicles crossing the intersection and resolve multi-vehicle conflicts within a reasonable time. This model can be used for traffic simulation at uncontrolled intersections and to provide test validation for automated driving systems.
在大多数关于非受控交叉口驾驶行为建模的研究中,多车交互场景通常被分为移动交叉行为和并线行为,并分别进行建模。然而,使用单一行为模型来准确表示不受控制交叉路口的一般驾驶行为是不合适的。在这种情况下,我们构建了在不受控制的交叉路口多车交互的一般驾驶行为模型。最初,我们采用 IMM 模型来预测驾驶员视野内车辆的移动。借鉴风险平衡理论和预览-跟随者理论,运用风险场理论评估车辆可能面临的潜在危险,从而帮助确定与驾驶员实际行动相一致的轨迹,同时满足风险约束条件。驾驶员的异质性通过风险阈值反映出来。当车辆陷入僵局时,该模型可以通过调整风险阈值来模拟驾驶员在不受控制的交叉路口交通拥堵中的行为。结果表明,我们的模型可以准确再现车辆通过交叉口时的优先级和轨迹,并在合理的时间内解决多车冲突。该模型可用于非受控交叉口的交通模拟,并为自动驾驶系统提供测试验证。

Perceiving the environment is one of the most fundamental keys to enabling Cooperative Driving Automation, which is regarded as the revolutionary solution to addressing the safety, mobility, and sustainability issues of contemporary transportation systems. Although an unprecedented evolution is now happening in the area of computer vision for object perception, state-of-the-art perception methods are still struggling with sophisticated real-world traffic environments due to the inevitable physical occlusion and limited receptive field of single-vehicle systems. Based on multiple spatially separated perception nodes, Cooperative Perception (CP) is born to unlock the bottleneck of perception for driving automation. In this paper, we comprehensively review and analyze the research progress on CP, and we propose a unified CP framework. The architectures and taxonomy of CP systems based on different types of sensors are reviewed to show a high-level description of the workflow and different structures for CP systems. The node structure, sensing modality, and fusion schemes are reviewed and analyzed with detailed explanations for CP. A Hierarchical Cooperative Perception (HCP) framework is proposed, followed by a review of existing open-source tools that support CP development. The discussion highlights the current opportunities, open challenges, and anticipated future trends.
感知环境是实现自动协同驾驶的最根本关键之一,而自动协同驾驶被认为是解决当代交通系统的安全性、机动性和可持续性问题的革命性解决方案。尽管目前计算机视觉在物体感知领域取得了前所未有的发展,但由于单车系统不可避免的物理遮挡和有限的感受野,最先进的感知方法在复杂的现实世界交通环境中仍然举步维艰。基于多个空间上分离的感知节点,合作感知(CP)应运而生,以解开自动驾驶的感知瓶颈。本文全面回顾和分析了 CP 的研究进展,并提出了统一的 CP 框架。本文综述了基于不同类型传感器的 CP 系统架构和分类方法,对 CP 系统的工作流程和不同结构进行了高层次的描述。我们回顾并分析了节点结构、传感模式和融合方案,并对 CP 进行了详细解释。提出了分层合作感知(HCP)框架,随后回顾了支持 CP 开发的现有开源工具。讨论强调了当前的机遇、公开挑战和预期的未来趋势。

Effective beam alignment is essential for vehicle-to-infrastructure (V2I) millimeter wave (mmWave) communication systems, particularly in high-mobility vehicle scenarios. This paper explores a three-dimensional (3D) vehicle environment and introduces a novel deep learning (DL)-based beam search method that incorporates an image-based coding (IBC) technique. The mmWave beam search is approached as an image processing problem based on situational awareness. We propose IBC to leverage the locations, sizes, and information of vehicles, and utilize convolutional neural network (CNN) to train the image dataset. Consequently, the optimal beam pair index(BPI)can be determined. Simulation results demonstrate that the proposed beam search method achieves satisfactory performance in terms of accuracy and robustness compared to conventional methods.

Interpretable Traffic Accident Prediction: Attention Spatial–Temporal Multi-Graph Traffic Stream Learning Approach 可解释的交通事故预测:关注时空多图交通流学习方法

Traffic accident prediction plays a vital role in Intelligent Transportation Systems (ITS), where a large number of traffic streaming data are generated on a daily basis for spatiotemporal big data analysis. The rarity of accidents and the absent interconnection information make it hard for spatiotemporal modeling. Moreover, the inherent characteristic of the black box predictive model makes it difficult to interpret the reliability and effectiveness of the deep learning model. To address these issues, a novel self-explanatory spatial-temporal deep learning model–Attention Spatial-Temporal Multi-Graph Convolutional Network (ASTMGCN) is proposed for traffic accident prediction. The original recorded rare accident data is formulated as a multivariate irregularly interval-aligned dataset, and the temporal discretization method is used to transfer into regularly sampled time series. Multiple graphs are defined to construct edge features and represent spatial relationships when node-related information is missing. Multi-graph convolutional operators and attention mechanisms are integrated into a Sequence-to-Sequence (Seq2Seq) framework to effectively capture dynamic spatial and temporal features and correlations in multi-step prediction. Comparative experiments and interpretability analysis are conducted on a real-world data set, and results indicate that our model can not only yield superior prediction performance but also has the advantage of interpretability.
交通事故预测在智能交通系统(ITS)中发挥着重要作用,每天都会产生大量的交通流数据,用于时空大数据分析。事故的罕见性和互联信息的缺失使得时空建模变得困难。此外,黑箱预测模型的固有特征使得深度学习模型的可靠性和有效性难以解释。针对这些问题,本文提出了一种新型的自解释时空深度学习模型--注意力时空多图卷积网络(Attention Spatial-Temporal Multi-Graph Convolutional Network,ASTMGCN),用于交通事故预测。将原始记录的罕见事故数据表述为多变量不规则区间对齐数据集,并采用时间离散化方法将其转换为规则采样的时间序列。当节点相关信息缺失时,定义多图来构建边缘特征和表示空间关系。多图卷积算子和注意力机制被集成到序列到序列(Sequence-to-Sequence,Seq2Seq)框架中,以有效捕捉多步预测中的动态时空特征和相关性。我们在真实世界的数据集上进行了对比实验和可解释性分析,结果表明我们的模型不仅能产生卓越的预测性能,而且具有可解释性优势。

Multiple graphs are defined to construct edge features and represent spatial relationships when node-related information is missing. Multi-graph convolutional operators and attention mechanisms are integrated into a Sequence-to-Sequence (Seq2Seq) framework to effectively capture dynamic spatial and temporal features and correlations in multi-step prediction. Comparative experiments and interpretability analysis are conducted on a real-world data set, and results indicate that our model can not only yield superior prediction performance but also has the advantage of interpretability.","PeriodicalId":13416,"journal":{"name":"IEEE Transactions on Intelligent Transportation Systems","volume":"25 11","pages":"15574-15586"},"PeriodicalIF":7.9,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motion planning for autonomous vehicles is commonly implemented via graph-search methods, which pose limitations to the model accuracy and environmental complexity that can be handled under real-time constraints. In contrast, reinforcement learning, specifically the deep Q-learning (DQL) algorithm, provides an interesting alternative for real-time solutions. Some approaches, such as the deep Q-network (DQN), model the RL-action space by quantizing the continuous control inputs. Here, we propose to use motion primitives, which encode continuous-time nonlinear system behavior as the action space. The novel methodology of motion primitives-DQL planning is evaluated in a numerical example using a single-track vehicle model and different planning scenarios. We show that our approach outperforms a state-of-the-art graph-search method in computation time and probability of reaching the goal.
自动驾驶车辆的运动规划通常通过图搜索方法来实现,这种方法对模型精度和环境复杂性造成了限制,无法在实时约束条件下进行处理。相比之下,强化学习,特别是深度 Q 学习(DQL)算法,为实时解决方案提供了一个有趣的替代方案。一些方法,如深度 Q 网络(DQN),通过量化连续控制输入来模拟 RL 动作空间。在此,我们建议使用运动基元,将连续时间非线性系统行为编码为动作空间。在一个数值示例中,我们使用单轨车辆模型和不同的规划场景对运动基元-DQL 规划的新方法进行了评估。结果表明,我们的方法在计算时间和到达目标的概率上都优于最先进的图搜索方法。
