济南经十路SMA混合料的质量控制

SMA属于间断级配沥青混合料,它依靠大量粗集料形成嵌挤并通过沥青玛蹄脂填充而形成高性能沥青路面,其设计与验证依然沿用马歇尔试验方法,另附加了其他试验方法以弥补马歇尔法的不足。SMA设计必须对其混合料是否形成嵌挤进行验证。

Non-commuters: the people who walk to work or work at home

The paper focuses on the socioeconomic characteristics of workers at home and those who walk to work and these are compared with commuters (those who travel to work by motorized transportation). Understanding of such characteristics of these people is useful for purposes of designing policies that encourage these forms of "travel" to work, if it is believed desirable for planning or environmental purposes. For example, subsidizing public transportation may also have an impact on the proclivity to work at home or walk to work. Using a large census data set for Israel, separate subsamples are analyzed for heads of household and for their spouses. Metropolitan areas as well as peripheral urbanized areas are analyzed separately. Logit analysis is used to identify those variables that affect the likelihood of different groups of people to walk to work or to work at home.It is shown that walkers to work tend to be lower-income, less-educated people with lower asset ownership rates. Females are overrepresented amongst them, while "high-status" professionals are underrepresented. Workers at home appear to be a more complex group. They tend to have higher levels of education and wealth than commuters, but earn less on average. They include proportionately more females. The likelihood of working at home increases with home size and with ownership of some durable goods. The workers at home may in fact be comprised of two or more differing groups with contrasting characteristics, one higher-income and higher-educated, the other with lower socio-economic indicators. Because they may be a heterogeneous group, development of planning policies to encourage non-vehicle commuting may require different policy tools for the different subgroups.

基于Matlab的公路养护作业区长度优化方法研究

公路养护工作是维持道路正常运行的基本保证,设置养护作业区往往需要封闭部分车道,这常会给道路上的交通流带来不利影响,对养护作业长度进行优化设计可以减少这些负面影响。在考虑道路交通流量的时间变化特性基础上建立了养护作业费用模型,利用Matlab工具初步实现了在道路交通流随时间变化情况下的作业区长度优化计算,并给出了具体算例。
