Heterogeneity in route choice during peak hours: Implications on travel demand management 高峰时段路线选择的异质性:对出行需求管理的影响
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-12 DOI: 10.1016/j.tbs.2024.100922
Traffic congestion has imposed considerable economic expenses and environmental challenges on metropolitan areas. Consequently, cities have implemented Travel Demand Management (TDM) strategies to mitigate this issue during peak hours. Although studies have investigated how individuals make decisions during commuting in response to TDM incentives, there is limited research on differences in route choices between trips to and from work, making the policies less effective. This study aims to fill this gap by using trajectory data from over 3,000 vehicles and examines the impacts of time-varying features, route characteristics, and built environment factors on route variability. Results indicate that factors such as expressway proportion, travel cost, and road density at the origin and destination locations have similar effects on route variability during morning and evening commuting. However, departure time, travel distance, and the number of traffic lights significantly differ in impacting route variability between the two scenarios. This study provides a foundation for optimizing route choices and alleviating traffic emissions during peak hours through advanced TDM measures. With more detailed and deliberate policies, citizens can enjoy urban mobility within a well-organized road network in a more sustainable and efficient way.
交通拥堵给大都市地区带来了巨大的经济损失和环境挑战。因此,城市纷纷实施出行需求管理(TDM)策略,以缓解高峰时段的交通拥堵问题。虽然已有研究调查了个人在通勤期间如何根据 TDM 激励措施做出决策,但对上下班出行路线选择差异的研究却很有限,这使得政策的效果大打折扣。本研究旨在利用 3,000 多辆汽车的轨迹数据填补这一空白,研究时变特征、路线特征和建筑环境因素对路线变化的影响。结果表明,快速路比例、出行成本、出发地和目的地的道路密度等因素对早晚通勤路线变化的影响相似。然而,出发时间、旅行距离和红绿灯数量对两种情景下路线变异性的影响却大不相同。这项研究为优化路线选择和通过先进的 "行车需求管理 "措施缓解高峰时段的交通排放奠定了基础。有了更详细、更周密的政策,市民就能以更可持续、更高效的方式,在井然有序的道路网络中享受城市交通。

Inferring in-home/out-of-home situations unreported in time-use surveys using supervised machine learning 利用监督机器学习推断时间使用调查中未报告的家庭内外情况
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-11 DOI: 10.1016/j.tbs.2024.100928
Time-use surveys provide useful data for travel analyses. However, the survey on time use and leisure activities (TULA) Questionnaire A, a representative time-use survey in Japan, does not include questions related to the locations of activities, thus making it difficult to use for travel analyses. This study proposes machine-learning methods to determine the in-home/out-of-home situations of TULA Questionnaire A using TULA Questionnaire B with activity locations as the training data. Random forest performs better than logistic regression and decision trees in the inference. The activity was the most important factor in determining the in-home/out-of-home situations, followed by the accompanying person and time of day. The inferred outputs in the TULA Questionnaire A included the individual-based out-of-home rate profiles and the proportions of mobile persons from 1996 to 2016. Using these outputs, we analyzed trip misreporting in household travel surveys. Comparisons with nationwide and Tokyo person trip (PT) surveys implied soft refusals and trip misreporting in travel surveys. The comparison with the nationwide PT surveys suggested higher soft refusals on weekends than on weekdays. The comparison with the 1998, 2008, and 2018 Tokyo PT surveys implied the increased soft refusal in PT surveys, particularly among the male group aged between 20 and 39 and the female group aged between 35 and 49 during 1998–2018. These results suggest that careful handling of recent household travel survey data may be required. In addition, the proposed machine-learning-based method enables us to utilize the rich sample of Questionnaire A for activity-based travel analysis in future studies.
时间利用调查为旅行分析提供了有用的数据。然而,作为日本具有代表性的时间利用调查,时间利用和休闲活动调查(TULA)问卷 A 并不包括与活动地点相关的问题,因此难以用于旅行分析。本研究提出了机器学习方法,使用带有活动地点作为训练数据的 TULA 问卷 B 来确定 TULA 问卷 A 的在家/外出情况。在推理中,随机森林的表现优于逻辑回归和决策树。活动是决定在家/不在家情况的最重要因素,其次是陪同人员和时间。TULA 问卷 A 的推断输出包括 1996 年至 2016 年基于个人的外出率概况和流动人员比例。利用这些输出结果,我们分析了家庭旅行调查中的旅行误报情况。与全国和东京个人旅行(PT)调查的比较意味着旅行调查中的软拒绝和旅行误报。与全国范围的 PT 调查相比,周末的软拒绝率高于工作日。与 1998 年、2008 年和 2018 年东京公共交通调查的比较表明,在 1998 年至 2018 年期间,公共交通调查中的软拒绝现象有所增加,尤其是在 20 岁至 39 岁的男性群体和 35 岁至 49 岁的女性群体中。这些结果表明,可能需要谨慎处理近期的家庭旅行调查数据。此外,建议的基于机器学习的方法使我们能够在未来的研究中利用问卷 A 的丰富样本进行基于活动的旅行分析。

Free interchange for better transit? Assessing the multi-dimensional impacts on metro to bus interchange behavior − insights from an explainable machine learning method 免费换乘带来更好的交通?评估地铁与公交换乘行为的多维影响--来自可解释机器学习方法的启示
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-11 DOI: 10.1016/j.tbs.2024.100923
This study investigates the impact of a newly implemented public transport interchange discount policy in Suzhou, China, focusing on its effects on metro-to-bus interchange behaviors across various spatial and temporal dimensions. Utilizing two distinct datasets spanning periods before and after the policy’s implementation, a comprehensive spatial–temporal analysis was conducted, covering weekdays, weekends, and holidays. A novel, real-time, distance-weighted methodology was developed to more accurately identify metro-to-bus interchange catchments, thereby refining the modeling scope. The study examines the interplay between land use, socio-demographic factors, and bus-related attributes—including a newly proposed operation-opportunity combined bus accessibility metric—using an explainable machine learning approach. Results indicate that the interchange discount policy has had an overall positive, though varied, impact on interchange behaviors, with the most pronounced effects observed during weekdays in central urban areas and at metro line bends. Specifically, 76.1 % of metro stations saw an increase in metro-to-bus interchange ratios on weekdays following the policy’s implementation, with increases observed at 66.4 % and 67.3 % of stations during weekends and holidays, respectively. Overall, the interchange ratio increased by 12.49 %, with a 17.45 % increase on weekdays. The analysis also reveals that factors such as bus accessibility, bus-to-bus interchange, and population density exhibit different effects depending on the time of week, with non-linear patterns emerging. The policy’s introduction shifted the impact thresholds for certain factors, initially triggering competition between bus and metro services but eventually leading to a synergistic rise in metro-to-bus transfers as bus-to-bus interchange ratios increased. Additionally, the policy altered the significance of population density, enhancing the attractiveness of multimodal interchange for users who previously favored other modes of transport.
本研究调查了中国苏州新实施的公共交通换乘折扣政策的影响,重点关注该政策在不同时空维度上对地铁与公交换乘行为的影响。利用政策实施前后的两个不同数据集,进行了全面的时空分析,涵盖了工作日、周末和节假日。研究还开发了一种新颖的实时距离加权方法,以更准确地确定地铁到公交换乘站的覆盖范围,从而完善建模范围。研究采用可解释的机器学习方法,检验了土地利用、社会人口因素和公交车相关属性之间的相互作用,包括新提出的运营-机会相结合的公交车可达性指标。结果表明,换乘折扣政策总体上对换乘行为产生了积极影响,但影响程度不一,其中在工作日的中心城区和地铁线路拐弯处观察到的影响最为明显。具体而言,在政策实施后,76.1% 的地铁站在工作日的地铁与公交换乘率有所上升,在周末和节假日,分别有 66.4% 和 67.3% 的地铁站的换乘率有所上升。总体而言,换乘率增加了 12.49%,其中工作日增加了 17.45%。分析还显示,公交可达性、公交换乘和人口密度等因素在不同的时间段会产生不同的影响,出现非线性模式。该政策的出台改变了某些因素的影响阈值,最初引发了公共汽车和地铁服务之间的竞争,但随着公共汽车与公共汽车换乘率的增加,最终导致了地铁与公共汽车换乘率的协同上升。此外,该政策还改变了人口密度的重要性,增强了多式联运换乘对以前偏爱其他交通方式的用户的吸引力。

Assessment of weather-driven travel behavior on a small-scale docked bike-sharing system usage 小规模停靠式共享单车系统使用情况下受天气影响的出行行为评估
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-11 DOI: 10.1016/j.tbs.2024.100927
Bike-sharing systems play a crucial role in encouraging sustainable transportation, and understanding their usage characteristics is essential for enhancing their contribution to urban mobility. This research seeks to investigate how weather conditions impact the utilization of a small-scale docked bike-sharing system. The study employed Generalized Linear Mixed Effects (GLME) models to analyze interactive events, using categorized weather parameters to represent various weather conditions. Several models were developed to comprehensively understand distinct travel behaviors and identify significant weather variables affecting the frequency of bike trips for transportation and leisure purposes. The findings reveal that rain had a significant deterrent effect on leisure cycling, particularly on weekdays. Cold and hot weather conditions exhibited a more pronounced impact on weekday bike trips, while weekend bike trips appeared to be less influenced by weather variables. The fall season was found to be the least favorable for leisure trips, while winter was determined to be the most unfavorable for transportation trips. Furthermore, hot days in the summer season negatively impacted bike usage only on weekdays. These insights have important implications for the development of a more resilient bike-sharing system, particularly in small-scale contexts. They provide valuable recommendations for tailored strategies to mitigate the impact of adverse weather conditions, thereby fostering an increase in usage of bike-sharing systems for both leisure and transportation purposes.
共享单车系统在鼓励可持续交通方面发挥着至关重要的作用,了解其使用特点对于提高其对城市交通的贡献至关重要。本研究旨在探讨天气条件如何影响小型有桩共享单车系统的使用。研究采用广义线性混合效应(GLME)模型来分析互动事件,使用分类天气参数来代表各种天气条件。研究建立了多个模型,以全面了解不同的出行行为,并确定影响交通和休闲自行车出行频率的重要天气变量。研究结果表明,下雨对休闲骑车出行有明显的阻碍作用,尤其是在工作日。寒冷和炎热的天气条件对工作日自行车出行的影响更为明显,而周末自行车出行受天气变量的影响似乎较小。秋季被认为是最不利于休闲出行的季节,而冬季则被认为是最不利于交通出行的季节。此外,夏季的炎热天气只对工作日的自行车使用产生负面影响。这些见解对发展更具弹性的共享单车系统具有重要意义,尤其是在小规模环境中。它们为制定有针对性的战略以减轻不利天气条件的影响提供了宝贵的建议,从而促进了共享单车系统在休闲和交通方面的使用率的提高。

Collecting population-representative bike-riding GPS data to understand bike-riding activity and patterns using smartphones and Bluetooth beacons 利用智能手机和蓝牙信标收集具有人口代表性的自行车骑行 GPS 数据,以了解自行车骑行活动和模式
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-11 DOI: 10.1016/j.tbs.2024.100919
Bike-riding GPS data offers detailed insights and individual-level mobility information which are critical for understanding bike-riding travel behaviour, enhancing transportation safety and equity, and developing models to estimate bike route choice and volumes at high spatio-temporal resolution. Yet, large-scale bicycling-specific GPS data collection studies are infrequent, with many existing studies lacking robust spatial and/or temporal coverage, or have been influenced by sampling biases leading to these data lacking representativeness. Additionally, accurately detecting bike-riding trips from continuously collected raw GPS data without human intervention remains a challenge. This study presents a novel GPS data collection approach by leveraging the combination of a smartphone application with a Bluetooth beacon attached to a participant’s bike. Aided by minimal heuristic post-processing, our method limits data collection to trips taken by bike without the need for participant intervention, carefully optimising between survey participation, privacy challenges, participant workload, and robust bike-riding trip detection. Our method is applied to collect 19,782 bike trips from 673 adults spanning eight months and three seasons in Greater Melbourne, Australia. The collected dataset is shown to represent the underlying adult bike-riding population in terms of demographics (sex, occupation and employment type), temporal and spatial patterns. The average trip length (median = 4.8 km), duration (median = 20.9 min), and frequency of bicycling trips (median = 2.7 trips/week) were greater among men, middle-aged and older adults. The ‘Interested but Concerned’ riders (classified using Geller typology) rode more frequently, while the ‘Strong and Fearless’ and ‘Enthused and Confident’ groups rode greater distances and for longer. Participants rode on roads/streets without bike infrastructure for more than half of their trips by distance, while spending 24% and 17% on off-road paths and bike lanes respectively. This population-representative dataset will be key in the context of urban planning and policymaking.
自行车骑行 GPS 数据提供了详细的洞察力和个人层面的流动性信息,这对于了解自行车骑行出行行为、提高交通安全和公平性以及开发高时空分辨率的自行车路线选择和交通量估算模型至关重要。然而,针对自行车的大规模 GPS 数据收集研究并不常见,许多现有研究缺乏强大的空间和/或时间覆盖范围,或受到取样偏差的影响,导致这些数据缺乏代表性。此外,在没有人工干预的情况下,从连续采集的 GPS 原始数据中准确检测自行车骑行次数仍是一项挑战。本研究提出了一种新颖的 GPS 数据收集方法,将智能手机应用程序与连接到参与者自行车上的蓝牙信标相结合。在最小启发式后处理的辅助下,我们的方法将数据收集限制在无需参与者干预的骑车行程上,在调查参与度、隐私挑战、参与者工作量和稳健的骑车行程检测之间进行了精心优化。我们的方法应用于收集澳大利亚大墨尔本地区 673 名成年人的 19,782 次自行车出行,时间跨度为八个月和三个季节。从人口统计学(性别、职业和就业类型)、时间和空间模式来看,所收集的数据集代表了潜在的成人自行车骑行人群。男性、中年人和老年人的平均出行长度(中位数 = 4.8 公里)、持续时间(中位数 = 20.9 分钟)和骑车出行频率(中位数 = 2.7 次/周)都更高。有兴趣但担心 "的骑行者(根据盖勒类型学进行分类)骑行频率更高,而 "坚强无畏 "和 "充满活力和自信 "的群体骑行距离更远、时间更长。按骑行距离计算,一半以上的参与者在没有自行车基础设施的公路/街道上骑行,而24% 和17% 的参与者在非公路道路和自行车道上骑行。这一具有人口代表性的数据集将成为城市规划和政策制定的关键。

The emergency accessibility analysis based on traffic big data and flood scenario simulation in the context of Shanghai hotel industry 基于交通大数据和洪水场景模拟的上海酒店业应急可达性分析
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-09 DOI: 10.1016/j.tbs.2024.100900
This paper presents a novel methodology for assessing emergency response capabilities in coastal cities in China amidst the challenges posed by global warming, rapid tourism industry growth, and increasing flood occurrences. Our approach integrates flood simulation, traffic big data, and web-based path navigation to evaluate the emergency response of the Fire & Rescue Service (FRS) to tourist hotels in Shanghai. The empirical study highlights the significant impact of transportation conditions, hotel locations, flood inundation intensity, and urban FRS distribution on emergency response effectiveness. It further demonstrates that existing traffic conditions heavily influence flood-induced emergency accessibility, with severe congestion adversely affecting spatial accessibility. The study also reveals that flooding events and real-time traffic can cause delays in emergency responses by altering optimal routes. Consequently, selecting the most efficient routes becomes crucial for enhancing a city’s emergency response capabilities. The results validate the efficacy of our proposed approach, which holds significant promise for improving emergency response capabilities in urban tourism settings when faced with disasters.
在全球变暖、旅游业快速发展和洪水日益增多的挑战下,本文提出了一种评估中国沿海城市应急响应能力的新方法。我们的方法整合了洪水模拟、交通大数据和基于网络的路径导航,以评估上海消防救援队(FRS)对旅游酒店的应急响应。实证研究强调了交通条件、酒店位置、洪水淹没强度和城市消防救援队分布对应急响应效果的重要影响。研究进一步表明,现有的交通状况严重影响了洪水引发的应急可达性,严重的交通拥堵对空间可达性产生了不利影响。研究还显示,洪水事件和实时交通会改变最佳路线,从而导致应急响应延迟。因此,选择最有效的路线对于提高城市的应急响应能力至关重要。研究结果验证了我们提出的方法的有效性,该方法有望在城市旅游环境面临灾害时提高应急响应能力。

The planning ethos of providing proximity-based services to all inhabitants has been prevailing recently, and underlines the importance of knowing areal differences in collective activity space (AS) of populations. Mobile phone signaling data (MSD) has great potentials for this end, especially in mega-cities with fast changing and spatially varying demographic composition. However, two problems need to be addressed when applying MSD-based AS measurement for planning practices, including the identification of regularly visited locations and the selection of measure indices. This paper proposes a three-step workflow to apply the MSD to measure local collective AS with considering addressing the problems. This three-step workflow aims to illustrate the procedure of using MSD to measure collective AS for supporting planning practice in urban China, with clarifying some key concerns when doing so. We apply the workflow to examine the spatial heterogeneity of the collective AS in Shenzhen City and discuss the transferability of the workflow in different social and institutional contexts.
为所有居民提供就近服务的规划理念近来十分盛行,这也凸显了了解人口集体活动空间(AS)的区域差异的重要性。移动电话信令数据(MSD)在这方面具有巨大的潜力,尤其是在人口构成快速变化、空间差异较大的特大城市。然而,在规划实践中应用基于 MSD 的活动空间测量时,需要解决两个问题,包括识别经常访问的地点和选择测量指数。本文在考虑解决这些问题的基础上,提出了应用 MSD 测量地方集体 AS 的三步工作流程。该三步工作流程旨在说明使用 MSD 测量集体自适应状态以支持中国城市规划实践的程序,并澄清测量过程中的一些关键问题。我们运用该工作流程考察了深圳市集体自治的空间异质性,并讨论了该工作流程在不同社会和制度背景下的可移植性。

Moderating effects of policy measures on intention to adopt autonomous vehicles: Evidence from China 政策措施对采用自动驾驶汽车意向的调节作用:来自中国的证据
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-08 DOI: 10.1016/j.tbs.2024.100921
Autonomous vehicles (AVs) can potentially revolutionize the transportation system, but the extent of their impact may depend on users’ attitude and AV-related policies. This paper seeks to provide a holistic view of the impacts of policy, attitudinal, and sociodemographic factors on AV adoption intention. An extension to the original Technology Acceptance Model is proposed by incorporating perceived enjoyment (i.e., how enjoyable respondents think using an AV will be) and policy factors. Four policy factors include the availability of financial incentives, awareness campaigns, traffic policies, and legislative measures. Using 1,831 survey responses in China, multiple linear regression models were estimated to quantify the direct impacts of the proposed policy and attitudinal factors on AV adoption intention. They also illustrate the moderating effects of these policies on the relationships between attitudinal factors and AV adoption intention. The study findings may be used to design future policy measures to facilitate a smooth transition to an era of AVs.
自动驾驶汽车(AV)有可能彻底改变交通系统,但其影响程度可能取决于用户的态度和与自动驾驶汽车相关的政策。本文试图从整体上探讨政策、态度和社会人口因素对自动驾驶汽车采用意向的影响。本文对原有的 "技术接受模型 "进行了扩展,加入了 "感知乐趣"(即受访者认为使用视听产品的乐趣)和 "政策因素"。四个政策因素包括经济激励措施、宣传活动、交通政策和立法措施。通过对中国 1 831 份调查问卷进行估计,建立了多元线性回归模型,以量化建议的政策和态度因素对采用自动驾驶汽车意向的直接影响。研究还说明了这些政策对态度因素和采用意向之间关系的调节作用。研究结果可用于设计未来的政策措施,以促进向电动汽车时代的平稳过渡。

Examining senior citizens in public transport: The role of digitalization, environmental concern, and traveler satisfaction 研究公共交通中的老年人:数字化、环境问题和乘客满意度的作用
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-07 DOI: 10.1016/j.tbs.2024.100924
Increasing the share of travelers using public transport is one way to address environmental problems such as carbon dioxide emissions. Senior citizens represent an increasingly important group in this transition, as they are increasingly mobile and make up a large share of the population. In this paper, we investigate senior citizen’s mobility decision-making, focusing on public transport. Through a survey of 5,000 people in three metropolitan areas in Sweden, we find that while senior citizens desire to live in harmony with nature, they are less likely to see car traffic as a cause of environmental problems. They also struggle with the development of digital service delivery options of public transport. For instance, they use apps less, and like using timetables on paper and signs at bus stops more than younger public transport users. Even so, they are more satisfied with public transport than younger travelers, indicating that many seniors like using public transport, despite lacking the environmental motivations to do so.
增加使用公共交通出行的比例是解决二氧化碳排放等环境问题的一个途径。在这一转变过程中,老年人是一个日益重要的群体,因为他们的流动性越来越强,在人口中所占比例也越来越大。在本文中,我们以公共交通为重点,对老年人的出行决策进行了调查。通过对瑞典三个大都市地区的 5000 人进行调查,我们发现,虽然老年人渴望与自然和谐相处,但他们不太可能将汽车交通视为环境问题的根源。同时,他们也对公共交通数字化服务的发展感到纠结。例如,与年轻的公共交通用户相比,他们较少使用应用程序,更喜欢使用纸质时刻表和公交站牌。即便如此,他们对公共交通的满意度仍高于年轻乘客,这表明许多老年人喜欢使用公共交通,尽管他们缺乏使用公共交通的环保动机。

Impact of attitude, behaviour and opinion of e-scooter and e-bike riders on collision risk in Singapore 新加坡电动摩托车和电动自行车骑手的态度、行为和观点对碰撞风险的影响
IF 5.1 2区 工程技术 Q1 TRANSPORTATION Pub Date : 2024-10-04 DOI: 10.1016/j.tbs.2024.100918
Active Mobility Devices (AMDs) such as electric scooters (e-scooters) and electric bikes (e-bikes) are increasingly used on shared paths and Park Connector Networks (PCNs) in Singapore, leading to frequent interactions between AMD riders, pedestrians, and cyclists. To ensure safety, it is crucial to understand the factors associated with collision risk related to these AMDs. To gain insights into the riders’ perspectives on the risk-taking behaviours and attitudes towards safety and sharing paths, a survey was conducted with 369 e-bike and 133 e-scooter riders across Singapore. The collected data was analysed to identify critical features of behaviour, attitudes, and opinions of e-scooters/e-bikes riders and their impact on perceived collision risk. Logistic Regression was used to select the most important behavioural features linked to collision risk, and significance of each was quantified by using the odds ratios in the chosen model. The results reveal that e-bike riders who regularly brake hard to avoid obstacles and highly value capacity of e-bike to carry goods face an increase in collision risk by 49.1% and 43.48% respectively. Those preferring quieter AMDs face 33.31% lower collision risk. Additionally, e-bike riders advocating for more traffic enforcement or the importance of slowing down when overtaking pedestrians face 20.69% and 38.84% lower collision risk respectively. E-scooter riders who manoeuvre quickly to dodge collisions or prioritize passenger-carrying capacity encounter a 142.25% and 67.43% higher collision risk, respectively. Furthermore, e-scooter riders willing to bend rules when not causing inconvenience to others face an increase in collision risk by 123.00%. These outcomes offer significant insights for the design and regulation of active mobility to safeguard all road users in a multi-modal transport environment.
在新加坡,电动滑板车(e-scooters)和电动自行车(e-bikes)等主动式移动设备(AMDs)越来越多地在共享道路和公园连接网络(PCNs)上使用,导致AMDs骑行者、行人和骑自行车者之间的频繁互动。为确保安全,了解与 AMD 相关的碰撞风险因素至关重要。为了深入了解骑行者对冒险行为的看法以及对安全和共用道路的态度,我们在新加坡对 369 名电动自行车骑行者和 133 名电动滑板车骑行者进行了调查。对收集到的数据进行了分析,以确定电动摩托车/电动自行车骑行者的行为、态度和观点的关键特征及其对感知碰撞风险的影响。采用逻辑回归法选出与碰撞风险相关的最重要的行为特征,并利用所选模型中的几率比对每个特征的重要性进行量化。结果显示,经常急刹车以避开障碍物的电动自行车骑行者和非常重视电动自行车载货能力的骑行者面临的碰撞风险分别增加了 49.1%和 43.48%。而喜欢较安静的 AMD 的骑行者的碰撞风险则降低了 33.31%。此外,主张加强交通执法或在超越行人时减速的电动自行车骑行者的碰撞风险分别降低了 20.69% 和 38.84%。为躲避碰撞而快速操纵电动摩托车或优先考虑载客量的电动摩托车骑行者的碰撞风险分别高出 142.25% 和 67.43%。此外,在不给他人造成不便的情况下,愿意遵守规则的电动滑板车骑行者面临的碰撞风险增加了 123.00%。这些结果为主动交通的设计和监管提供了重要启示,以保障多模式交通环境中所有道路使用者的安全。
