Factors influencing travel mode choice among families with young children (aged 0–4): a review of the literature

Life events, such as the birth of a child, disrupt habitual travel behaviour and provide a valuable opportunity to influence the adoption of sustainable transport practices. However, in order for sustainable travel practices to be adopted, an understanding is required of the factors that influence travel mode choice among families with young children. Research in this field is particularly timely given many in the millennial generation, a comparably large cohort, are approaching this life stage. This comprehensive literature review develops a framework of factors influencing travel mode choice among families with young children. The findings reveal a multitude of factors influence decisions about mode choice, and, in particular, encourage travel by car, when travelling with young children. The paper concludes with an agenda for future research about travel among families with young children, a largely overlooked group of transport users.     

基于历史保护的老城区公共交通改善研究

受历史保护等诸多因素制约,我国许多城市的老城路网条件较差,交通拥堵严重,公共交通发展水平滞后。如何改善老城交通环境,构建宜居、活力、创新的老城,是社会各界共同关注的焦点。文中以佛山老城为例,提出基于历史保护的老城公共交通改善策略。对公交线网、公交场站、公交资源整合、配套管理等方面进行了研究。     

公路网规划环境影响评价中的不确定性分析

公路网规划环境影响评价中的不确定主要来自公路网规划方案的不确定和环境信息的不确定。具有普遍性、传递性、累积性和可降低性,对决策者存在着较大的干扰,但是可以通过使用基于情景分析的预测方法、广泛开展公众参与以及通过多方协作的方式开展环境影响评价工作等方法来降低。     

浅谈城市公共交通存在的问题及建议——以兰州市为例

目前,城市公共交通中存在很多问题,单纯依靠道路建设和交通管理来扩大路网供应能力不能解决交通拥挤问题,交通需求总是趋于超过道路供给。如果没有有效的措施来抑制个体交通的拥有和使用,将导致城市交通的全面恶化。因此,在完善道路网络的同时,必须尽快建立有竞争力的公共交通体系,支持城市的可持续发展。     

Locating rental stations and bikeways in a public bike system

To determine the spatial distribution of rental stations and bikeways in a public bike system, this paper proposes a facility location and network design model. The model is developed as a multi-objective programing problem that considers four objectives (minimizing cyclist risk, maximizing cyclist comfort, minimizing adverse impacts on traffic and maximizing service coverage) and multiple constraints (monetary budget, network connectivity, station spacing, bikeway types, station number and value ranges of decision variables). The ε-constraint method solves the programing problem for the public bike system in Daan District, Taipei City, Taiwan. The nine non-dominated alternatives generated are all markedly better than existing locations of rental stations and bikeways. Scenario analysis results indicate that increasing the construction budget for bikeways significantly improves cyclist safety and comfort whilst increasing the adverse impact on traffic. Planners can use this model to develop public bike systems that spatially integrate rental stations and bikeway networks.     

Initial public offerings in the port industry: exploring the determinants of underpricing

The capital-intensive nature of the port industry and the long payback period of port investments traditionally determine high financial needs for operating the business. Due to the growing financial requirements for developing greenfield mega-projects and feeding international terminal operators’ overseas expansion, equity markets are expected to extend their role in promoting the industry. In this perspective, the underpricing phenomenon, which represents a direct cost for the issuer during initial public offering (IPO) and discourages companies from going public, is neglected by port literature. The paper explores the antecedents of IPO underpricing in ports. Building upon extant finance and port literature, firm characteristics, transaction features, and country-specific variables are tested as determinants of IPOs’ initial returns. For the aim of this study, 58 port-related IPOs taking place on international stock exchanges are examined, and ordinary least squares regression analysis is performed. The study offers unprecedented understandings of the phenomenon and supports port managers in facing financial challenges. Before launching the IPO, financial executives are invited to carefully identify time-window opportunities, and to monitor underwriters’ reputation when selecting financial partners. Findings bring insights for policymakers, as the public listing of port companies emerges a viable option for implementing port reform.     

How Do Governments Support the Development of Public Private Partnerships? Measuring and Comparing PPP Governmental Support in 20 European Countries

Abstract

Taking an institutional perspective, in this article we develop an index of the governmental support for public private partnership (PPP) — a ‘PPP Governmental Support Index’ (GSI) — which aims to measure the extent to which national governments provide an institutional framework that is either conducive or preventive for the introduction and diffusion of PPPs within transport infrastructure and other sectors. First, based on a substantive review of the literature, we define the elements of the PPP GSI, including the policy and political commitment regarding PPPs, the legal and regulatory framework, and the presence/absence of dedicated PPP-supporting arrangements. Second, we calculate the PPP GSI for 20 European countries, cluster them and compare similarities and differences in national governmental support of infrastructure PPPs. Third, we explore the potential link between national institutional index scores and infrastructure PPP activity in the 20 countries. Lastly, we discuss the potential and usefulness of the presented PPP GSI, as well as methodological limitations, and elaborate on how this index might be utilised to strengthen future comparative research on PPP in transport and other sectors.     

The planning and analysis of a new group rapid transit system: the SkyCabs monobeam system in Auckland

This paper examines a case study of the SkyCabs system as a way to alleviate some of the traffic problems of Auckland, New Zealand. SkyCabs is an elevated two-way monobeam carrying light eight-seater cabs on tracks on each side of the beam, available on demand, providing fast, pollution-free, unimpeded travel above the footpath with panoramic views of the city. The aim of this study is to investigate the attractiveness of implementing the SkyCabs system to and from Auckland central business district (CBD) and Auckland international airport by examining four variables: different routes, different number of stops/stations, different passenger demand levels, and different number of cabs in the system. The analysis utilizes geographical information system and simulation tools for the various scenarios considered. The results show that it is possible to assess the cost–benefit of alternative routes in terms of those four variables and rate of return on investment.
