OpenStreetMap (OSM) data is a valuable open-source resource for various transportation, traffic, and planning applications. However, OSM network data lack operating traffic speed information, which is critical for transport planning and operations. Addressing this shortcoming, this study leverages commercial vendor data (to serve as ground truth) with exogenous, open-source variables characterizing local transport infrastructure, land use, and demographic information to predict average congested traffic speeds on OSM networks. Three machine-learning models were tested and estimated for OSM links with and without speed limit information in the Denver metropolitan region. Among these, XGBoost performed best, with mean absolute errors of 3.27 and 3.62 mph for links with and without speed limits, respectively. The developed models accurately predicted traffic speeds for different hours and days of the week compared to ground truth data. Using these predicted speeds, drive accessibility scores were computed for the Denver region for different time periods using the Mobility Energy Productivity (MEP) metric to understand the impact of congestion on energy-efficient accessibility. Results show that congestion-adjusted drive accessibility can be significantly lower compared to accessibility calculated using free flow speeds. Specifically, weekday evening hours saw a 42 % drop in accessibility due to reduced speeds, particularly around downtown Denver. Across the Denver metro region, approximately half as many opportunities and jobs are accessible in under 20 min by car during the evening peak period relative to free flow conditions. These findings underscore the importance of using congestion-adjusted operating speeds rather than speed limits in accessibility calculations, as reliance on speed limits can substantially overestimate energy-efficient drive accessibility in large, car-centric cities susceptible to significant congestion. The methodology presented here could further enrich OSM network data, making them useful for an even broader range of transportation applications.
OpenStreetMap (OSM)数据是各种交通、交通和规划应用程序的宝贵开源资源。然而,OSM网络数据缺乏运行交通速度信息,这对交通规划和运营至关重要。为了解决这一缺点,本研究利用商业供应商数据(作为基础事实)和外生的、开源的变量来表征当地交通基础设施、土地使用和人口统计信息,以预测OSM网络上的平均拥堵交通速度。在丹佛大都会地区,对有和没有限速信息的OSM链路进行了三种机器学习模型的测试和估计。其中,XGBoost表现最好,在有限速和没有限速的情况下,平均绝对误差分别为3.27和3.62英里/小时。与地面真实数据相比,开发的模型准确地预测了一周中不同时间和天数的交通速度。利用这些预测速度,利用交通能源生产率(MEP)指标计算丹佛地区不同时间段的可达性得分,以了解拥堵对节能可达性的影响。结果表明,与使用自由流速度计算的可达性相比,拥堵调整后的可达性显著降低。具体来说,由于速度降低,工作日晚上的可达性下降了42%,特别是在丹佛市中心附近。在整个丹佛都会区,与自由交通条件相比,在晚高峰时段,开车不到20分钟就可以获得大约一半的机会和工作机会。这些发现强调了在可达性计算中使用拥堵调整运行速度而不是限速的重要性,因为在容易出现严重拥堵的以汽车为中心的大型城市,依赖限速可能会大大高估节能驾驶的可达性。本文提出的方法可以进一步丰富OSM网络数据,使其对更广泛的运输应用有用。

Studies concerning the location choices of enterprises are predominantly focus on manufacturing enterprises, with limited attention given to service enterprises. This paper examines Beijing, whose services account for more than 80 % of GDP, to ascertain whether enhanced accessibility through the expansion of subway network facilitates new service enterprises to capitalize on agglomeration economies, ultimately contributing to the transformation of the urban landscape. Using a matched dataset comprising 16,571 gird cells, each measuring 1 × 1 km in size, and information on newly registered service enterprises in Beijing from 2007 to 2018, we employ a mult-period difference-in-difference (DID) estimation methodology, leveraging exogenous shocks from the opening of new subway lines, to examine the causal relationship between subway openings and the location decision of service enterprises. Our findings indicate that the subway network positively influences the establishment of service enterprises, with a 53.8 % increase in newly registered service enterprises following the opening of a new subway line. Furthermore, the agglomeration effects of subway network are more salient for newly registered producer service enterprises, which tend to cluster in central areas, whereas consumer service enterprises demonstrate a preference for agglomeration in the city's periphery, thereby contributing to the reconfiguration of the city's urban structure.
关于企业区位选择的研究主要集中在制造业企业,对服务业企业的研究较少。本文以服务业占GDP的80%以上的北京为研究对象,探讨通过地铁网络的扩张提高可达性是否有助于新的服务业企业利用集聚经济,最终促进城市景观的转变。本文利用16571个网格单元(每个网格单元的尺寸为1 × 1 km)和2007 - 2018年北京新注册服务企业的信息,采用多期差分估计方法,利用新地铁线路开通带来的外生冲击,检验地铁开通与服务企业选址决策之间的因果关系。研究发现,地铁网络对服务业企业的设立有正向影响,新开通地铁后,新注册的服务业企业增加53.8%。此外,地铁网络的集聚效应对新注册的生产性服务业企业更为显著,这些企业倾向于向中心区域集聚,而消费服务业企业则倾向于向城市外围集聚,从而促进了城市结构的重构。

Establishing a scientific mechanism for allocating carbon allowances in the transportation sector is vital for achieving net-zero emissions targets, especially considering China's significant regional disparities. Nonetheless, the current methods are inadequate. By exploring the causal mechanism of transportation CO2 emissions (TCE), this study addresses the aforementioned gap by developing a carbon allowance allocation method utilizing innovative econometric tools. The method calculates the cost of carbon emission reductions in each province using the non-radial directional distance function (NDDF). We constructed a three-dimensional spatial (SEE) transportation carbon quota allocation model grounded in Stability, Equity, and Efficiency, aimed at facilitating scenario analysis up to 2030. Results highlighted: (1) There is a positive correlation between transportation carbon quotas and the economic scale of each province, with Guangdong Province reaching the highest at about 76 million tons (low-carbon scenarios), further demonstrating that China's transportation carbon emissions have not yet decoupled from economic growth; (2) the marginal carbon abatement costs across provinces vary significantly, exhibiting a pattern of higher costs in the west and lower in the east, with a price range of RMB 40–690 per ton; (3) provinces focused on green transportation, such as Beijing, and those driven by economic driven, like Hebei, can achieve Pareto improvement and balance economic development with carbon emission reductions through reasonable trading. The study provides a methodological basis for China's transportation carbon quota allocation system and offers guidance on selecting development models for different regions.

Our transportation systems have encountered male bias in their design and evaluation for many years due to a lack of data from female users. Despite being a relatively new mode of transportation, e-micromobility has had greater uptake by male users from its inception. Yet, the gendered analysis and reporting of e-micromobility has not been analysed in detail on a large scale. This review identified 292 papers across 37 different countries that have conducted participant-based research into e-micromobility, to understand how gender was reported and analysed in the samples used in the studies. This identified that half of all papers reviewed had a male majority sample, while only 15 % had an equal split of male and female participants. 45 % of the studies (n = 133) reported gender differences, suggesting that gender does impact on e-micromobility use, with considerably more data on male users compared to female users. There was also a lack of reporting on non-binary gender data. With the application of gender factors that have been previously established in the transport domain, this review paper also identifies gender data gaps in areas such as care related journeys, encumbered travel and ergonomic design. The importance in accounting for the role of gender in the development of policy targeting e-micromobility is also presented from the findings of the review. The paper calls for more careful consideration of gender in the design and reporting of e-micromobility studies and presents recommendation that are applicable to a broad range of stakeholders in the e-micromobility domain.

Bicycle infrastructure has been found to increase nearby residential property values. However, most evidence for this economic impact is limited to a single city. This study investigates the pre- and post-treatment effects of different types of bicycle facilities on the values of single-family and multifamily homes in 11 cities in the United States from 2000 to 2019. We utilize a quasi-experimental approach with matching techniques and hedonic models to track down the changes in the sales price of residential properties over time within an 800-m buffer of bicycle facilities. We found a mixed impact of property value appreciation, depreciation, and no change in the sales price by different types of bicycle infrastructure including on-street and off-street facilities on single-family and multifamily residential properties across the 11 cities. Single-family and multifamily properties near off-street-only facilities experienced appreciation in Los Angeles, Minneapolis, and Cleveland. Meanwhile, single-family homes near on-street-only facilities tended to decrease their values in Columbus, Eugene, Philadelphia, and Tucson, and increase only in Minneapolis. All properties within 800 m of both on-street and off-street facilities saw their values increase in Columbus and Minneapolis. However, we did not find a statistically significant effect of bicycle infrastructure on housing values in Portland, San Francisco, and Seattle. Findings from our study will inform decision-making and planning for bicycle infrastructure while ensuring the equitable distribution of these facilities and affordable housing for disadvantaged populations.

This paper presents an insightful journey into understanding how travellers in the Northeast England perceive and interact with both conventional and emerging automated bus services. Employing a comprehensive methodology, our research scrutinizes data collected from 417 regional respondents via online questionnaires, integrating a blend of quantitative, qualitative, and spatial data points. This approach not only uncovers nuanced attitudes towards public transportation but also sheds light on the potential implications and acceptance of automated bus (AB) services, a fundamental element in shaping the future of urban mobility. The narrative aimed at (i) identifying present socio-demographic clusters and their travel behaviour, (ii) analysing perceptions regarding public transport with an emphasis on bus services, (iii) discovering attitudes towards AB systems and (iv) establishing the likelihood of a travel shift towards ABs.
The quantitative analysis applied Multiple Correspondence Analysis, unveiling five distinct socio-demographic clusters: (1) full-time employed, car-dependent individuals; (2) flexibly working individuals with mixed travel modes; (3) retired, car-dependent persons; (4) unemployed individuals primarily relying on walking and bus services; and (5) employed students utilizing various public transport and active travel modes. Furthermore, Categorical Principal Component Analysis revealed four key attitudinal components influencing bus service perceptions: (a) safety, quality, and comfort; (b) accessibility and availability; (c) cost and reliability; and (d) punctuality and preferences for alternatives. The qualitative dimension covered content and sentiment analysis on responses to open-ended questions about automated buses. This analysis highlighted mixed sentiments, with 56 % positive and 44 % negative mentions. Key connotations with automated buses included expectations of reduced accidents and safer roads, enhanced reliability and frequency of services, potential job losses, diminished social interaction, and concerns over personal security. The study culminates in a spatial analysis, synthesizing the socio-demographic clusters, attitudinal components, and a comparative assessment of traditional versus automated bus services.

Borrowed size and borrowed administrative power: Effects of high-speed rail network on industrial upgrading and variegated externalities in the Yangtze River Delta, China 借来的规模与借来的行政权力:高铁网络对长三角地区产业升级与多元外部性的影响

While the externalities of urban size on regional transportation infrastructure effects have been extensively discussed, the role of urban administrative power has received comparatively less scholarly attention. This study delves into the impact of high-speed rail (HSR) development on urban industrial upgrading and regional development, focusing on both economic and administrative externalities. By applying the concepts of ‘borrowed size’ and ‘agglomeration shadow,’ we analyze the effects of HSR on industrial upgrading in the Yangtze River Delta (YRD) region using panel data from 199 county-level units between 2000 and 2017. Employing multi-stage difference-in-differences (DID) and difference-in-difference-in-differences (DDD) models, our findings reveal that HSR significantly catalyzes industrial upgrading in the YRD, with a notable reduction in the output value of the secondary sector by 4.4 % and an expansion of the tertiary sector by 7.4 %. Additionally, this study indicates a positive correlation between urban size and manufacturing sector exit, while administrative power enhances the service sector's concentration in HSR-connected regions.

虽然城市规模对区域交通基础设施效应的外部性已经被广泛讨论,但城市行政权力的作用却受到相对较少的学术关注。本文从经济外部性和行政外部性两个方面探讨了高铁发展对城市产业升级和区域发展的影响。本文运用“借用规模”和“集聚阴影”的概念,利用2000 - 2017年199个县域单位的面板数据,分析了高铁对长三角地区产业升级的影响。采用多阶段差异中差异(DID)和差异中差异(DDD)模型,我们的研究结果表明,高铁显著促进了长三角地区的产业升级,第二产业产值显著下降4.4%,第三产业产值显著增长7.4%。此外,研究还发现城市规模与制造业出口呈正相关,而行政权力增强了高铁连接地区服务业的集中度。这些发现不仅有助于现有的关于高铁在产业升级中的作用的学术研究,而且还提出了一种新的方法方法,通过交通基础设施作为中介机制的视角,将交通地理学和城市政治经济学联系起来。

The local structure has a decisive impact on the structural resilience of the Global Crude Oil Maritime Transportation Network (GCOMTN). However, existing studies ignore the significant local characteristics of ports that arise from the unique transport patterns of crude oil tankers. In this study, we construct the GCOMTN using AIS data of crude oil tankers from 2020 and develop a framework for assessing structural resilience at a finer granularity. Specifically, we introduced motif structures to characterize local structural features and proposed a sub-network perspective to evaluate the structural resilience of ports. We then explore the structural resilience of both network-wide and port-level under three intentional attack scenarios. The results indicate that closed motifs are the most vulnerable, disappearing rapidly under intentional attacks. The GCOMTN structure is particularly sensitive to failures at strategically located ports. Conversely, individual ports demonstrate greater resilience in such scenario, even though their local structures tend to be inherently unstable. This study offers valuable insights for the International Maritime Organization (IMO) to collaborate effectively with port authorities, ensuring alignment in the goal of maintaining stable crude oil transportation.
局部结构对全球原油海上运输网络(GCOMTN)的结构弹性具有决定性影响。然而,现有的研究忽略了原油油轮独特的运输方式所产生的港口显著的地方特征。在本研究中,我们使用2020年以来的原油油轮AIS数据构建了gcomn,并开发了一个更细粒度的结构弹性评估框架。具体而言,我们引入motif结构来表征局部结构特征,并提出了子网络视角来评估港口的结构弹性。然后,我们在三种故意攻击场景下探讨了网络范围和端口级别的结构弹性。结果表明,封闭基序是最脆弱的,在故意攻击下迅速消失。gcomn结构对战略位置港口的故障尤其敏感。相反,个别港口在这种情况下表现出更大的弹性,尽管它们的本地结构往往本身就不稳定。这项研究为国际海事组织(IMO)与港口当局有效合作提供了有价值的见解,确保保持稳定原油运输的目标一致。

COVID-19 has a great impact on the volume and frequency of air transportation. To minimise the transmission risk, civil aviation authorities imposed travel restrictions and led to changes of the global and regional air traffic network (ATN). Considering the potential for future similar propagable events that may challenge the operation of the ATN again, it is crucial to develop more efficient air route adjustment schemes (ARAS) to better respond to propagable outbreaks. This study first examines the development patterns of propagable events and constructs a spatial temporal evolution model under the coupling of event development and traffic flow. Based on the dynamic process of the spatial temporal evolution model, the study explores the resilience assessment method of the ATN throughout the entire cycle of events. This study proposes a methodological framework to intervene in the air route reduction and recovery of any two connected airport pairs based on the prioritised network centrality (PNC) during all rising and descending phases of propagatable outbreaks to achieve overall ATN network resilience enhancement, and the model is validated by the case under COVID-19 background. The numerical study shows that the adjustment of air route capacity has a significant impact on the control of the introduction of cases in the initial phase. However, there is no significant impact on controlling the risk of propagation if the destined regions face widespread local propagation. This explains that travel restriction and quarantine of the ATN do not contribute to controlling the local propagation of regions but can ameliorate the severity of the overall outbreak at the network level by affecting the spreading sequence across the network. To improve the network resilience in response to propagable outbreaks, The air route adjustment scheme considering prioritised network centrality (ARAS-PNC) approach can capitalise on the impact of network performance and outbreak progression and respond better at the network level with greater network efficiency and lower network-wide effective case rate.
新冠肺炎疫情对航空运输量和频率产生重大影响。为了尽量减少传播风险,民航当局实施了旅行限制,并导致全球和区域空中交通网络(ATN)的变化。考虑到未来可能发生的类似可传播事件可能再次挑战空中交通网络的运作,制定更有效的航线调整计划(ARAS)以更好地应对可传播的疫情至关重要。本研究首先考察了可传播事件的发展模式,构建了事件发展与交通流耦合下的时空演化模型。基于时空演化模型的动态过程,探索了整个事件周期的ATN恢复力评价方法。本研究提出了一种方法框架,在可传播性疫情的所有上升和下降阶段,基于优先网络中心性(PNC)干预任意两个连接机场对的航线减少和恢复,以实现整体ATN网络弹性增强,并通过COVID-19背景下的案例验证了该模型。数值研究表明,航路容量的调整对初始阶段引入病例的控制有重要影响。然而,如果目标区域面临广泛的局部传播,则对控制传播风险没有显著影响。这说明,对ATN的旅行限制和隔离并不能控制区域的局部传播,但可以通过影响网络上的传播顺序,在网络层面上减轻整体疫情的严重程度。考虑到优先网络中心(ARAS-PNC)方法的航线调整方案可以利用网络性能和爆发进程的影响,在网络层面上做出更好的响应,提高网络效率,降低网络范围内的有效病例率。

The predominant mode of public transport in South Africa originates from the informal sector, specifically “paratransit”. Vehicles carry up to 23 passengers and are still propelled by internal combustion engines. We investigate the feasibility of using electric vehicles without negating the loss of opportunities by drivers and owners. We propose that scheduling of the electric vehicles is one important cornerstone towards electrification. We developed a fast-executing heuristic scheduling algorithm that allows for multiple vehicle depots in the transport network; simultaneous electric and internal combustion engine vehicle deployment; determining the number of charging stations; partial charging; and scheduled charging with intermittent electricity supply. The scheduling algorithm achieves the minimum number of vehicles to execute the passenger demand in shorter total distances, outperforming current approaches. The algorithm demonstrated multi-objective optimisation by minimising the vehicles, the number of charging stations, and the average trip delays of a schedule.
南非的主要公共交通方式来自非正规部门,特别是 "准公共交通"。这些车辆最多可搭载 23 名乘客,仍由内燃机驱动。我们研究了使用电动汽车的可行性,同时不否认驾驶员和车主的机会损失。我们提出,电动车辆的调度是实现电气化的一个重要基石。我们开发了一种快速执行的启发式调度算法,允许在运输网络中设置多个车辆仓库;同时部署电动汽车和内燃机汽车;确定充电站的数量;部分充电;以及在间歇性供电的情况下进行计划充电。该调度算法能在更短的总距离内实现最少的车辆数量以满足乘客需求,优于目前的方法。该算法通过最小化车辆、充电站数量和计划的平均行程延迟,实现了多目标优化。
