American journal of epidemiology
|June 8, 2023
概括
交通镇静措施 (TCM) 显示,其减少道路碰撞的证据很弱. 然而,当地道路上的TCM与较少的严重事故有关,这突显了需要有效的动脉道路战略的需要.
科学领域:
- 城市规划是城市规划.
- 运输工程 运输工程 运输工程
- 公共卫生 公共卫生
背景情况:
- 交通缓和措施 (TCM) 旨在通过物理修改来提高道路安全.
- 以前关于TCM有效性的研究经常使用前/后设计,引发了对有效性的担忧.
- 需要一个纵向设计,以更好地评估TCM的影响.
研究的目的:
- 用纵向设计来评估TCM的有效性.
- 评估TCM对加拿大蒙特利尔致命或严重碰撞的影响.
- 根据道路类型来确定TCM有效性的潜在差异.
主要方法:
- 一项纵向研究从2012年到2019年评估了8个TCM (例如,路边延伸,速度).
- 在蒙特利尔 (北克省) 的十字路口和人口普查区层面分析了数据.
- 贝叶斯条件波桑回归与随机效应被用于模拟碰撞数据.
主要成果:
- 主要在地方道路上实施了TCM,大多数碰撞都没有发生.
- 总体而言,微弱的证据表明,TCM与减少碰撞无关.
- 小组分析表明,在当地道路交叉点上的TCM可能会降低碰撞率 (IRR:0.31).
结论:
- 在大多数碰撞发生的动脉道路上,TCM的有效性有限.
- 当地道路交叉点的TCM显示,碰撞率的潜在降低.
- 需要进一步的研究来确定动脉道路的有效TCM,以提高整体道路安全.

Manipulation and Analysis
47
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Social Traps
22.4K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Design Example: Alignment of a Road Line Using GIS
73
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...
