信息资源在汽车维修业中的应用研究

信息资源是我国社会发展中的重要战略资源,将其应用到汽车维修业的发展中,可以帮助企业作出更加正确的决策,使企业能够在激烈的市场竞争中立于不败之地。但是就当前情况来看,汽车维修业存在较严重的人才匮乏情况,且传统的信息交换无法适应汽车维修业的不断发展,这就需要加强对信息技术的应用,为汽车维修业提供更加丰富的信息资源。鉴于此,本文就从多个方面对信息资源在汽车维修业中的应用进行探究,希望能为相关从业人员提供一些有效参考依据。     

快速测量法在隧道施工中的应用

测量工作伴随隧道开挖的整个过程,因洞内条件的限制,洞内开挖断面的测量放样工作占用的时间不少,直接影响着隧道的施工安全、进度。文中通过对待测断面坐标系中的坐标与隧道三维坐标的关系,编制简易的程序,利用简易普及的全站仪进行数据输入、分析,能快速地给出待测断面的坐标,通过几尾隧道的施工放样实践,收到了较好的效果。

A multiobjective land development optimization model: the case of New Castle County,Delaware

This paper develops a multiobjective optimization model to consider transportation impacts of the future development of land. The output of the model is the best location and type of land use that has minimal negative transportation effects and uses the maximum available public transportation infrastructure. It provides tools for both planners and transportation engineers and enables them to consider different scenarios of possible policies and land development. Since multiple objectives and their nonlinear structures are considered, the model is solved using mixed integer nonlinear programming. The final results are shown in both tabular and graphical format. The effectiveness of the model is applied to the northern part of New Castle County, Delaware. The results show that the model successfully finds the best locations for both residential and commercial land uses in order to meet several criteria discussed in the paper.

Strava Metro data for bicycle monitoring: a literature review

ABSTRACT

Monitoring bicycle trips is no longer limited to traditional sources, such as travel surveys and counts. Strava, a popular fitness tracker, continuously collects human movement trajectories, and its commercial data service, Strava Metro, has enriched bicycle research opportunities over the last five years. Accrued knowledge from colleagues who have already utilised Strava Metro data can be valuable for those seeking expanded monitoring options. To convey such knowledge, this paper synthesises a data overview, extensive literature review on how the data have been applied to deal with drivers’ bicycle-related issues, and implications for future work. The review results indicate that Strava Metro data have the potential—although finite—to be used to identify various travel patterns, estimate travel demand, analyse route choice, control for exposure in crash models, and assess air pollution exposure. However, several challenges, such as the under-representativeness of the general population, bias towards and away from certain groups, and lack of demographic and trip details at the individual level, prevent researchers from depending entirely on the new data source. Cross-use with other sources and validation of reliability with official data could enhance the potentiality.
