快速公交（BRT）线路布设优化算法研究

快速公交（BBT）在我国方兴未艾，而目前缺乏实用的快速公交线网布局优化方法。针对传统直达客流方法应用于快速公交线网布局优化的不足，根据快速公交的特点和功能定位，提出了以直达客流运输密度最大和直达客流绕行系数最小为目标的快速公交线网布局双层非线性优化模型，对模型合理性进行了论证，并提出了简单容易操作的实用求解算法。     

A study of carpooling behaviour using a stated preference web survey in selected cities of India

This paper analyses how people perceive the idea of carpooling and evaluate preferences while making a decision to join a carpool. Analysing data from a web-based stated preference survey in India reveals that cognitive attitudes play a significant role in evaluating the perceived advantages and disadvantages of carpooling whereas intentions to carpool are associated with perceived negative evaluations. A factor analysis identifies two latent attitudinal factors: a ‘time–convenience’ factor that discourages carpooling and a ‘private–public cost’ factor that encourages carpooling. The study analyses the influential attributes – extra travel time, walking time to reach meeting point, waiting time at pickup point and cost savings – as explanatory variables for the utility of carpooling. Cost savings prove to be the most significant attribute when combined with other attributes, followed by extra travel time. The study provides the implications to policy-makers of designing promotional tools to improve the propensity of carpooling among single occupant vehicle drivers.

三轴磁传感器性能标定方法研究

三轴磁传感器被广泛应用于空间磁场测量。利用高精度磁环驱动器、16位A/D、D/A数据卡和格拉斯磁环构建了三轴磁传感器的灵敏度和分辨率标定系统。依据当地地磁场垂直分量为35uT的特性得出了传感器3.52V/Gass的灵敏度。建立闭环测试系统的基础上,通过对采集到信号进行滤波去噪和功率谱分析,对比分析得到传感器的分辨率是6nT。     

Comparing operator and users costs of light rail, heavy rail and bus rapid transit over a radial public transport network

A model to compare three alternative forms of public transport - light rail, heavy rail and bus rapid transit - is developed for an urban network with radial lines emanating from the borders to the city centre. The theoretical framework assumes an operation aimed at minimising the total cost associated with public transport service provision, which encompasses both operator and users costs. The decision variables are the number of lines (network density) and the frequency per period for each mode. This approach has no prejudices a priori in respect of whether a specified delivery scenario is aligned with existing modal reputation. Rather, we establish the conditions under which a specific transit mode should be preferred to another in terms of the operator (supply) and user (demand) side offerings. The model is applied using data from Australian cities, suggesting that in most of the scenarios analysed a high standard bus service is the most cost-effective mode, because it provides lower operator costs (infrastructure, rolling stock and operating cost), access time costs (due to a larger number of lines) and waiting time cost (due to larger frequencies of operation). A rail mode, such as light rail or heavy rail, may have a lower total cost only if it is able to run faster than bus rapid transit, and the difference in speed is enough to outweigh the bus advantage on operator cost and access and waiting times.
