综合交通信息对小汽车通勤出行链的影响研究

为了量化综合交通信息对小汽车通勤者的诱导效果,实施网络调查获取出行行为数据,分析了调查数据的统计特性,并对比有无综合交通信息时通勤出行链的时间、空间和结构特征,然后,基于SP数据建立通勤者在综合交通信息条件下出行选择行为的网络广义极值模型(NGEV模型),并利用BIOGEME软件包进行求解.通过分析参数标定结果,得到如下结论:综合交通信息下通勤者进行复杂出行链选择公共交通的概率更低,小汽车通勤出行链(私人交通模式)在泊位数充足的情况下转向其他交通模式的倾向性较明显.

山地城市建成环境对居民小汽车拥有影响研究——以贵阳市为例

为分析山地城市建成环境对居民小汽车拥有的影响，探究不同坡度下居民地形感知对小汽车拥有影响的差异，采用贵阳市中心城区不同坡度下的小区居民调研数据，引入3个观测变量来评价居民的地形感知，将结构方程模型（SEM）计算出的潜变量适配值融入Logit模型中，构建包含潜变量和显变量的SEM-Logit模型来研究主客观建成环境与小汽车拥有的关系。结果表明:坡度对小汽车拥有产生积极影响，但不同坡度下的地形感知对小汽车拥有的影响有所不同。在地形条件相对较好的环境中，当小区坡度小于8%，居民对地形感知并不强烈，并认为从小区步行到公共交通站点的距离和时间花费在其承受范围内。因此，地形感知并未对小汽车拥有造成显著影响；在小区坡度为8%~15%时，地形感知对小汽车拥有产生显著负效应。生活在该小区类型的居民，尤其是收入相对偏低的居民，更喜欢选择电动自行车出行，削弱了小汽车拥有量；当小区坡度大于15%时，小区坡度与小汽车拥有量具有正相关性。该小区类型的道路坡度大，居民出行过程中通常会经历频繁的上下坡，造成出行时间花费长，继而形成强烈的地形感知。这严重降低了居民出行选择步行或骑行的可能性，转而提升了小汽车拥有的概率。同时，在SEM-Logit模型中也证明了除地形因素外，家庭年收入、到地铁站最近距离、土地利用混合度、目的地可达性、出行态度对小汽车拥有具有较大影响。      

A nationwide study of factors associated with household car ownership in China

Car ownership is growing very rapidly in China; whilst this is a reflection of sustained economic growth, it presents a major challenge to Chinese transport policymakers. The consequences of China's motorization also extend beyond the national borders, however, via mechanisms such as increased demand for new automobiles produced in North America and Europe and the global atmospheric concentration of greenhouse gases. Chinese cities are also experimenting with innovative transport policies to manage increasing car ownership, which in a number of cases go beyond the menu of policy options that have traditionally been considered in the West. Despite policy interest for these reasons, China's motorization process is poorly understood, in part due to a scarcity of relevant data.This paper contributes to the body of literature regarding this phenomenon by drawing on a unique data resource: the 2011 wave of the China Household Finance Survey (n = 8438 households). This is a disaggregate national-scale survey dataset developed to monitor economic conditions in China, though to the authors' knowledge the CHFS has not previously been employed to study patterns of car ownership.We report a set of three analyses, to identify factors associated with: 1) whether a household owns at least one car, 2) multiple car ownership, and 3) whether a household owns a new car. Amongst other empirical results, we find that living in a rural area is negatively associated with car ownership, net of confounding effects, and that within towns/cities poor accessibility (i.e. long travel time) to the town/city centre is also negatively associated with car ownership. These findings regarding spatial effects are contrary to typical findings in the West, where car ownership is generally lowest in urban centres.An earlier version of this study was presented at the 2017 Transportation Research Board conference.     

Analyzing Hong Kong's inbound tourism: The impact of the COVID-19 pandemic

This study empirically investigates the determinants and drivers of Hong Kong's inbound tourism using data from January 2019 to December 2020. Five of Hong Kong's major regional tourism source markets are selected: Japan, Malaysia, the Philippines, Singapore, and South Korea. Our empirical results suggest that the COVID-19 pandemic has had significant negative impacts on the tourism and aviation sectors in Hong Kong that are asymmetric in the source and destination countries. In addition, international travel control imposed by the Hong Kong government is often defined according to the pandemic situation in the tourism source countries, Hong Kong's inbound visitor volume is also significantly affected by the Hong Kong government's response to COVID-19 infection cases in the tourism origin markets. Our empirical results also suggest that the flying distance to Hong Kong and high tourism costs in Hong Kong reduced visitor arrival demand, whereas increased aviation services and tourism market potential contributed to tourism growth. These results suggest that the tourism industry and government agencies should cooperate to recover when the pandemic is under good control, so that Hong Kong will be regarded as a preferred and safe destination for travelers and visitors. Our study emphasizes the complementarity between pandemic control and tourism recovery. Pandemic control involves extra tests and quarantine requirements on passengers, more vigorous border control. These operational and associated financial requirements call for government support to the tourism and aviation sectors in the early stage of recovery to create a positive feedback loop.

论香港地下空间开发的规划、立法与发展经验

 海滨城市香港山多平地少,土地是极为稀少的资源,但山岭地貌和坚硬晶质火成岩岩体很适合开发地下洞室和隧道。20世纪70年代、80年代起,就开始考虑发展地下空间,以满足都市发展的需求。为此,政府开始有计划地进行工程可行性研究,并进行相关的立法工作,为规范地下空间的开发,建立了一套完整的地下空间开发体系。结合工程实例,就香港地下空间开发的研究、规划、开发、管理和立法作简要介绍。     

The shape of MaaS: The potential for MaaS Lite

Mobility as a Service (MaaS) is about improving mobility for people. Since Gothenburg piloted the first multi-modal Mobility as a Service (MaaS) scheme from 2012, there have been many further attempts at introducing connected and bundled services globally, invariably provided as a mobile app and a single, simple ticketing interface. As in any emerging paradigm, the varying flavour, or ‘shapes’ of MaaS that are piloted reflect the search for a sustainable business model and connectivity between transport operators at varying levels that includes risk reallocation and data sharing. The varying levels of success of MaaS and Mobility on Demand (MOD) lead the authors to propose MaaS Lite, which reflects an incremental approach to MaaS based on a simpler organisational arrangement that does not depend upon the introduction of a Mobility Operator as a new player. MaaS Lite also recognises that most trips are not complex at all, often based on one or two connected mechanised modes that meets highly local needs, including FMLM service connectivity.Overall, MaaS is not a ‘one size fits all’ solution for all regions but the benefits of the highly targeted MaaS Lite could realise early public benefits as a first step in the development of a multi-phased ‘services road map’ that evolves towards the implementation of multi-modal, region-wide operationally integrated MaaS. Case studies in Hong Kong and Brisbane demonstrate the merits of MaaS Lite in these two contrasting environments having different regulatory regimes, population densities and levels of private car ownership.     

Is vehicle ownership in urban india influenced by the availability of high quality dedicated public transit systems?

As India's economy grows, so too does the number of people who can afford to own vehicles. A downside of this rapid increase in private vehicle ownership is a corresponding increase in traffic congestion, air pollution, and carbon emissions. Although affordability may be one reason for the shift toward commuting via private vehicles, another contributing factor could be the quality of public transportation. The objective of this paper is to determine whether private vehicle ownership in large urban areas in India is influenced by the presence of high quality dedicated public transit systems. Consumer expenditure survey data acquired from the National Sample Survey Office (NSSO) for the year 2009–2010 were used to develop a vehicle ownership model for 26 Indian cities with a population of at least one million. The results show that the availability of public transportation has a negative correlation to motorcycle/moped ownership but has no strong effect on car ownership. These results should encourage governments in developing economies to invest in high-quality dedicated public transit systems.
