公交驾驶员心理状况影响因素分析与疾病判别模型

为对公交驾驶员心理疾病实现精准干预，维护乘客生命及公共交通安全，本文通过分析公 交驾驶员心理状况影响因素构建心理疾病类型判别模型。选用由基本信息、身体状况、生活状 态、驾驶行为、组织认同感、人格特征以及职业压力与工作倦怠问卷组成的公交驾驶员心理健康 状况调查问卷，对400名城市公交驾驶员展开问卷调查研究，通过皮尔逊相关性检验分析心理状 况影响因素，利用K-means聚类算法和多元Logistic回归模型判别和分析心理疾病，提出相应干 预措施。结果表明：人格冷怒和驾驶行为、身体状况、生活状态、组织认同感显著正相关，职业压 力与工作倦怠和这4个影响因素显著负相关，相关性均较强，因此，构建心理疾病判别模型时排除 与多个影响因素均呈较强相关性的人格冷怒、职业压力与工作倦怠这两个影响因素；被调查的公 交驾驶员中，心理状态良好型、轻度心理疾病型、严重心理疾病型占比分别为52%、34%、14%；公 交驾驶员心理疾病类型与身体状况、驾驶行为以及生活状态显著正相关，与驾驶行为的相关性最 强，身体状况次之，生活状态最弱。

How does air pollution influence cycling behaviour? Evidence from Beijing

It is widely believed air pollution is an obstacle to cycling as it has negative effects on cyclists’ health outcomes and deteriorates their cycling experiences. However, the empirical studies investigating the impact of air pollution on cycling behaviour remains scarce. The aim of this paper is to fill the gap by looking at Beijing as a case study. The authors conducted a survey of 307 cyclists on the days with different levels of air quality in terms of concentration of PM_2.5 in 2015. The results show that in the polluted weather, those who persist in cycling are more likely to be male, over 30 years old, lower income or those who travel short distances. Specifically, female cyclists have a higher tendency to shift from cycling to public transit than the males and medium and high-income earners are more likely to shift to using a car than low income earners. The residents’ subjective perceptions of safety and comfort have major effects on their cycling behaviour. A higher perception of comfort and safety is related to a higher possibility of continuing cycling when air quality became polluted. Cycling for commuting trips is less likely to be replaced by other modes than cycling for non-commuting trips, such as shopping. Results of this study reveal that improving air quality in a metropolitan area such as Beijing has co-benefits of cycling renaissance. The huge investments into cycling infrastructure should be integrated with policies designed to create an attractive environment for cycling.     

Understanding job-housing relationship and commuting pattern in Chinese cities: Past,present and future

There are debates about whether job-housing balance and short commuting distances could be achieved through government intervention in Western countries. However, few studies have been carried out in developing context. The present study aims to fill in this knowledge vacuum by studying how China’s changing socio-spatial context, particularly the spatial ideas of danwei, influences job-housing relationships and commuting patterns from a historical perspective. The results clearly show that the dominant trend in commuting patterns in Chinese cities has changed from intra-danwei commuting before 1978 to reverse commuting from the city center to the inner suburbs in 1978–1998, to long-distance suburb-to-city commuting since 1998. The findings suggest that government intervention could be helpful in achieving shorter commute in China, and that urban planning and policy that promote mixed land-use and job-housing balance should be considered. Some limitations of government intervention are also discussed.     

南京纬三路过江通道泥水盾构带压开舱开挖面最小支护压力确定

南京纬三路过江通道采用两台直径14．93m的泥水盾构施工。盾构机在长距离穿越粗砂、卵砾石等复合地层时,刀盘刀具会产生较大磨损,因而需要进行停机带压检修。带压作业时,部分隧道开挖面仅由气压进行支护。针对气压支护开挖面在带压开舱时开挖面最小支护压力的设定问题,通过建立有限元三维开挖面稳定分析模型,研究了极限状态下盾构开挖面保持稳定的最小支护压力,并与工程计算和相关模型试验结果进行比较,确定了具有一定安全系数的开舱支护压力。     

Meeting the management challenges of the Decade of Action for Road Safety

In low- and middle-income countries, the high price paid for mobility in terms of human loss and suffering is forecast to rise to unprecedented levels. More than 50 million deaths and 500 million serious injuries on the world's roads can be projected with some certainty over the first 50 years of the 21st century, unless sustained new initiatives are taken. This paper addresses the emergence of road safety as a development priority over the last decade and the management challenges facing the planned global response aimed at bringing road safety outcomes in developing countries under control. It outlines the decade of advocacy that created the UN Decade of Action for Road Safety 2011–2020 and related Global Plan, and highlights the concern that over the coming decade low and middle income countries will face considerable management challenges in successfully implementing related measures and sustaining their delivery. The paper discusses new road safety management tools that have been developed by the World Bank and ISO to provide assistance to countries and organizations within an integrated framework that ensures that measures taken are properly sequenced and adjusted to their absorptive and learning capacities. It concludes that strengthened institutions and the accelerated knowledge creation and transfer central to this, plus scaled-up investment and increased international cooperation and development aid are critical to the successful achievement of the Global Plan's ambitious goal.
