A Novel Methodology for Measuring Individual-level Travel Regularity: A Joint Time-space-frequency Perspective

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： Xinwei Ma Xiaolin Tian hongjun cui Minqing Zhu Xia Li School of Civil and Transportation Engineering， Hebei University of Technology School of Architecture and Art Design， Hebei University of Technology

Individual travel behaviors demonstrate a degree of regularity， particularly concerning time， space， and frequency repetition. Measuring the regularity of individual travel behavior contributes to understanding variations among individuals and provides opportunities for personalized transportation services. However， previous measurement methods have not comprehensively addressed these three aspects simultaneously or sufficiently captured the repetition of "basic travel behaviors"， while also relying on diverse data types without a comprehensive methodology covering multiple datasets. To address these research gaps， this paper presents an innovative method for measuring the regularity of individual users， which considers the repetition of basic travel behaviors along with temporal， spatial， and frequency dimensions. Applying this method to historical trip data from bike-sharing and subway systems has illustrated the effectiveness and applicability of the approach proposed in this paper. The findings suggest the broad applicability of this method across various data types， provided that the data allows for the extraction of information regarding users' travel origins and destinations. Moreover， this method effectively produces a regularity value to assess and compare the overall regularity of users， surpassing previous limitations that solely relied on using frequency as an initial filter or distinguishing users as regular or irregular based solely on frequency thresholds.

A review of key technologies for integration of electric vehicle-charging station-transportation network-grid based on bibliometric analysis

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： hongjun cui Xiushi Dong Yue Su Minqing Zhu Weimin Li Xinchang Zhang School of Civil and Transportation Engineering， Hebei University of Technology School of Architecture and Art Design， Hebei University of Technology Hebei Expressway Group Limited School of International Business， Tianjin Foreign Studies University

Electric vehicles (EVs) are instrumental in balancing the operation of the transportation networks and grids for the dual attribute of power and traffic load. Current research community has gained significant efforts on key technologies for the integration of electric vehicle-charging station-transportation network-grid (VSNGI). Therefore， a synthetic review on this domain is needed. In this context， the VSNGI research included in the Web of Science (WOS) was synthetically analyzed using bibliometric methods， the software VOSviewer and CiteSpace. The results show that the internationally interested VSNGI research is in a period of rapid development in terms of publication volume， national， institutional， and journal performance. The cited literature provided work accumulation in five aspects: “the impact and control of EVs on the grid”， “design of EV charging stations”， “integration of charging stations and grids”， “integration of charging stations and transportation networks” and “coupling of the transportation network and grid”. Then， the latest progress was summarized in four aspects: “characterization methods of spatiotemporal features of road network demand and grid load”， “SNG collaborative layout technology”， “VSN orderly guidance technology”， and “VNG interactive response technology”. Lastly， the problems and prospects in the VSNGI research were discussed. The joint efforts of researchers from multiple disciplines are required by the development of the VSNGI field. The VSNGI research will be of crucial significance in the transformation of the transportation field.

An Optimization Method for Seismic Reliability of Regional Road Networks

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： Fei Wang Minqing Zhu hongjun cui Qihang Zhou Xinyu Sun Di Zhou Xinwei Ma School of Architecture and Art Design， Hebei University of Technology School of Civil and Transportation Engineering， Hebei University of Technology Tianjin Sino-German University of Applied Sciences Hebei Expressway Group Limited， Shi Huang Branch

To enhance the efficacy of seismic reliability assessments within regional road networks， this study introduces the constructs of Forbidden Edge Sets and Iterable Edge Sets within the framework of the Quick Fixed-node Unconnected Subgraph Algorithm (QFUS). Through optimization of the subgraph iteration process， the Quick Subgraph Algorithm (QSA) has been developed， exhibiting a diminished temporal complexity. Examining the topological architecture of road network systems， this research proposes the notion of road unit criticality. The corresponding equations have been formulated and empirically validated. Addressing the seismic optimization challenge of road networks， an optimization model has been constructed， and the Additive Edge Method has been introduced， aiming to minimize the requisite investment for enhancements. The algorithms QSA and the Additive Edge Method were applied to the road network in the vicinity of Zhangjiakou for empirical analysis. The results indicate that the QSA algorithm enhances the computational efficiency of network reliability by 33.04% in comparison to the QFUS algorithm. The metric of road unit criticality effectively quantifies the influence of various road unit reinforcement strategies on the seismic reliability enhancement of road network systems. The Additive Edge Method proposed herein is shown to minimize the analytical scope required for road units within the network and achieves cost minimization for seismic optimization of the road network. The scientific validity and logical soundness of the Additive Edge Method have been corroborated through the application of the control variable technique.

随着信号交叉口的非机动车流量激增,非机动车通过交叉口时的膨胀特性也进一步凸显。针对该现象所带来的冲突问题,在分析非机动车膨胀特性的基础上,提出信号交叉口直行非机动车冲突风险实时评估方法。选取天津市4个典型城市交叉口,通过视频分析软件,获取非机动车的行驶行为数据,分析膨胀特性下直行非机动车行驶行为特征。在此基础上,通过K-means聚类分析将直行非机动车的行驶区域划分为释放区、膨胀区和汇入区这3个区域。构建以直行非机动车不同行驶区域为一级指标,不同区域内的行驶行为特征为二级指标的信号交叉口直行非机动车冲突风险评价体系,提出基于改进熵权法的非机动车冲突风险熵计算方法。以天津市围堤道交叉口为例进行风险评估,结果表明,其冲突风险主要集中于车辆超车与并行行为频发的地带,风险点变化和分布与车辆膨胀过程中风险变化趋势一致,可以为信号交叉口非机动车冲突风险研究提供一定的参考。

为研究个体异质性对于大型活动参与意向选择的影响,构建了基于潜在类别选择模型的大型活动参与意向选择模型。使用D-optimal设计法生成了大型活动参与意向调查中的选择情景,并假设以天津市奥体中心为大型活动举办地,对天津市居民开展了大型活动参与意向调查。根据调查获取的数据,使用EM算法对模型进行了参数估计。模型结果表明:天气、活动时间、票价、活动类型、政策复杂度等是影响大型活动参与意向选择的主要因素。模型将潜在的大型活动参与者划分为天气敏感型群体、活动时间敏感型群体、票价敏感型群体3类,分别占样本总体的30%、15%、55%,区分度为0.81,其中类别1对天气类型最为敏感,对活动举办时间和票价不敏感;类别2对活动举办时间最为敏感,对天气的敏感程度较低;类别3对票价最为敏感,对活动时间和政策复杂度不敏感。

轨道交通客流量影响因素是轨道交通方面研究的一个关注点,不同站点客流量的时空非平稳性被认为与站域建成环境有关。通过构建时空地理加权(geographically and temporally weighted regression,GTWR)模型,揭示了土地多样性、密度、站点属性3个方面因素在时间和空间维度上对天津市轨道交通客流量的影响。结果表明:相较于传统的地理加权(geographically weighted regression,GWR)模型和最小二乘法(ordinary least squares,OLS)模型,GTWR具有更好的拟合优度;公交站点密度对轨道交通客流产生促进作用,尤其在工作日的早晚高峰时段和中心城区位置;市中心的商业设施在工作日晚高峰吸引更多的地铁乘客,而在近郊区它们在早高峰吸引更多的地铁乘客;人口密度促进轨道交通的客流量;充足的停车场设施数量可以吸引更多的轨道交通乘客。
