Design Example: Alignment of a Road Line Using GIS

49
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

126
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Social Traps01:41

Social Traps

22.3K
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...

Strategies for Assessing and Addressing Confounding

100
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Framing Effects03:26

Framing Effects

7.4K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Routes of Persuasion02:20

Routes of Persuasion

64.1K
Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Area of Science:

  • Transportation Engineering
  • Road Safety
  • Economic Appraisal

Background:

  • Current road safety appraisal tools often overlook indirect benefits.
  • Economic studies for road safety countermeasures typically focus only on safety benefits, neglecting travel time and environmental impacts.
  • Lack of models to evaluate indirect benefits hinders comprehensive economic appraisal.

Purpose of the Study:

  • To quantify the impact of indirect benefits in the economic appraisal of road safety infrastructure investments.
  • To demonstrate the role of reduced crashes in evaluating indirect benefits.
  • To inform improved business cases for road safety infrastructure.

Main Methods:

  • Utilized data from 9 European countries.
  • Analyzed a 20-year infrastructure improvement program in the Netherlands.

road safety
  • Conducted a quantitative study to assess indirect benefits.

    • Main Results:

    • Indirect benefits increased the total value of benefits by 7%.
    • Enhanced cost-effectiveness led to an increase in selected countermeasures.
    • Travel time benefits accounted for the largest share (6%) of indirect benefits.

    Conclusions:

    • Indirect benefits significantly impact benefit computation and countermeasure selection.
    • Incorporating indirect benefits, especially travel time, is crucial for robust economic appraisals.
    • Further research on travel time benefits from countermeasure implementation is recommended.
